    Introduction


    This thread serves as a roadmap for those who wish to attach an external Graphics Processing Unit (eGPU) to a notebook/laptop computer. Connection may be achieved through an ExpressCard, mPCIe slot, or Thunderbolt port.

    Note: For those running Windows 7, you can install the eGPU without rebooting your system. Simply and the turn the system to standby system and attach the PE4L. Your system will return to its desktop presets once it detects the PE4L. You will immediately see a significant upgrade in the performance.

    Pros and Cons

    Pros

    • eGPUs are quite inexpensive: PE4L with HD5770+120W, GTS450+120W, GTX460-1GB+430W, GT430+72W, HD5670+72W. A x2 capable kit using a PE4H must also be acquired.
    • As long as your system has an expresscard OR a mPCIe slot, you can perform the conversion.
    • You can expect an increase in video performance as much as 10x.
    • Provides additional HDMI video+audio, s-video and VGA out
    • Provides dual-link DVI connection for 2560x1600 LCDs
    • Can be attached to a Windows 7 system without requiring a reboot
    • The attachment is not permanent. The eGPU can be used on a different computer or be attached to 2 or more computers at once.
    • Those with an expresscard 2.0 system, or who have performed a x2 1.0 setup can expect to see an additional 30-60% increase in performance.
    • eGPUs provide an additional USB port when connected to an expresscard slot
    • Time-share your desktop video card b/w your desktop and notebook system.
    • Perform CUDA/OpenCL processing for applications that support it.
    • Can use physX/ hybrid physX & game detaill

    Cons

    • A 12V PSU is necessary drive the desktop eGPU
    • An external LCD/CRT/TV is necessary to connect to display at highest FPS
    • It may be necessary to boot the eGPU Setup 1.x from a disk image or USB stick to overcome error 12 issues
    • Possible bandwidth is restricted: a x1/x2/x4 link represents 1/16, 1/8 or 1/4 the bandwidth of a x16 slot.
    Pre-purchase FAQ
    1. How does a DIY eGPU differ from a Villagetronic ViDock3/4?
    The Villagetronic ViDock 3/4 is a PE4L packaged together with a PSU. The flexibility offered by eGPUs make them better solution than a ViDock ¾ for the following reasons:
    • eGPUs are a heck of a lot cheaper than the ViDock ¾: US$92-delivered PE4L versus US$215-delivered for the ViDock3. A GTX460-768MB eGPU setup this is a savings of some US$230.
    • If you are unsatisfied with the performance of your eGPU, you can resell it with minimal losses. Villagetronic has a very strict return policy means higher ebay reselling losses.
    • Has DIY eGPU Setup 1.x software to overcome error 12: cannot allocate resources issues.
    • Developed the x1E tweak and custom NVIDIA Optimus drivers to deliver highest possible performance. DNA drivers for ATI cards are available too.
    • mPCIe AND expresscard systems are supported. Villagetronic can only use expresscard systems.
    • PCI reset delay circuit to boot past problematic bios with unit switched on (PE4L 1.5+/PE4H 2.4+).
    • x2 capable on some systems: x2 1.0 provides ~60% better performance than x1 1.0.
    • A PSU can be added to match the video card.
    • Can be enclosed inexpensively.
    • Since it does not come with a chassis, it can be configured with unrestricted video card sizes and cooling apparatus.
    • PE4H allows desktop video card to be hosted externally and shared b/w notebook and desktop (@x4 1.0 speed via HP4A.
    • Uses a very inexpensive mini HDMI interconnect.
    2. How to check if your laptop is eGPU compatible?
    If the system has a dGPU then ensure its switchable with the Intel 4500MHD/HD/HD3000/HD4000 providing primary video if you want to do a higher performance Optimus x1.Opt setup with allows accelerated graphics to the internal LCD as well as an external LCD.
    Any notebook run with 2GB of RAM can be eGPU compatible. A very high percentage at 3GB will also allow such configuration. If your system runs at 4GB you’ll need to check your free PCIe configuration space to host it, as detailed below:
    (Update 3-14-2012)
    A DSDT override extending the root bridge into 36-bit can allow ALL systems with a 64-bit CPU and chipset, if you are using Windows 7 and the latest drivers with up to 48GB of RAM installed can be made eGPU compatible. The solution for such a DSDT override solution is detailed below.
    • if the system has a switchable iGPU+ATI/AMD dGPU or switchable iGPU+NVIDIA Optimus dGPU configuration then can use Setup 1.x you’ll need to connect the eGPU to use the PCIe space. This requires the disabling of the dGPU. While it is known that all Intel chipset systems with NVIDIA or ATI/AMD switchable graphics can function this way, the Series-6 AMD switchable graphics has not be tested fully.

    If the system has only a dGPU or an iGPU, which is not switchable, then check the system's TOLUD+Large Memory for an issues related to running 4GB+. Check in Device Manager. Set View to "Resources by connection" & expand the Memory tree like shown.
    If you have large memory memory entry, then the eGPU can be hosted in 36-bit PCIe space. If not, then you’ll need a TOLUD being 3.25GB or less to host the eGPU 3at 2-bit PCIe space. Yu can verify the situation by using a 8 digit memory address to analyze the first PCI bus and then cross reference with the table below:
    First PCI bus with 8 digits memory addressTOLUD
    E00000003.5GB
    D00000003.25GB
    C00000003GB
    B00000002.75GB
    A00000002.50GB

    As long as TOLUD is equal or lower than 0xD0000000 (3.25GB) your notebook will have enough 32-bit PCI space for a eGPU to work with 4GB or more of system RAM. See details. Some examples:

    To be absolutely sure an eGPU can be accommodated requires booting Setup 1.x and performing an 32-bit PCI "All" compaction. Once complete, you should see 256MB free shown in the Status window. If not, then you only have 128MB of contiguous free space. At this point, you’ll have to consider another method, such as a NVidia Fermi card use a fragmented 128MB+64MB+32MB PCI BAR so might still be able to be allocated where ATiAMD cards that require a straight 256MB contiguous block cannot.
    This likely comes across as a confusing process. In essence, simply boot Setup 1.x, run Save Diags->compact_fails, then Save Diags->Windows_fails following the prompts. Boot back to Windows, mount the Setup 1.x image, archive the v:\diag folder with Winrar/WinZIP, upload to mediafire.com to review your diagnostic output.

    3. I don't have an ExpressCard slot. Can I still do use a eGPU?
    Yes, if have an accessible mini PCIe (mPCIe) slot via the underside covers that works with your wifi card, as show here, then could use a PE4L-PM3N or PE4H-PM3N mPCIe setup. The example Dell XPS15 L502, Acer 1810TZ, HP 2510P and Lenovo X61T below all use a PM3N mPCIe-based eGPU.
    NOTE: WWAN mPCIe slots with only USB pins connected (pin 36+38) rather than PCIe pins (23, 25, 33, 35) cannot do a eGPU.
    USB-to-ExpressCard adapters cannot be used since they uses just the 480Mbps USB pins on an ExpressCard slot.
    mini PCI slots can't be used. Can see the difference between mini PCI and mini PCIe here.

    4. Can I make this work using just my notebook's LCD display?
    The desktop video card outputs to it's HDMI/VGA/DVI connector. The notebook's LCD display uses a LVDS input on your systemboard with no external jack to connect to it. Meaning then they cannot be physically connected together unless adapt a US$30 ebay kits allowing external input to the internal LCD as discussed, which only quite an advanced user would ever attempt.
    Another more elegant solution would use a HDMI input expresscard as described at Play PS3/X360 on laptop screen using new HDMI Input Express Card. . Though current costs of $170 for the item makes it unattractive AND you'd need to then do a mPCIe eGPU implementation.
    There are however these less drastic ways of getting your accelerated graphics card to render to the internal LCD, all of which will have lower performance than when running using an external LCD:
    • NVIDIA Optimus driver provides a transparent internal LCD cloning mode for systems with a 4500MHD/HD/HD3000/HD4000 iGPU primary video when using a NVIDIA GTS4xx/GTX4xx card.
    • Use Lucidlogix virtu drivers to provide transparent output using the internal LCD if you have a Sandy Bridge cpu. (timohour)
    • Ultramon/Chung Gun method can clone from the desktop eGPU's window to the internal LCD for windowed games/apps.
    • USB 3.0 framegrabbers have sufficient bandwidth to capture the image from the desktop eGPU and pipe it back to your notebook's display.

    It is not feasible to use USB 2.0 framegrabbers. The desktop video card outputs HDMI/S-Video. To try to clone the output from the desktop video card via a USB frame grabber can be done, but consider say 1280x800x32-bit = 4MB per image. If gaming at 30FPS that's 120MB/s bandwidth required. USB 2.0 is 480Mbps (60MB/s in *best case* scenario.. more like 30MB/s in real-life).

    5. (Performance) What affects the performance of a eGPU?
    The x1 1.0 PCIe link restricts performance from normal desktop levels. PCIe Scaling Analysis shows x16, x2 and x1 performance. Compared to x16 2.0 we can summarize that there is 50% performance loss at x1 1.0 and 20% performance loss at x2 1.0 link speeds. Or x2 1.0 is 60% faster than x1 1.0.ViDock and BPlus PE4L are using the same x1 ExpressCard/mPCIe pins so we will get exactly the same performance using either solution. Only ways either solution will see improved performance is by:
    RE5 Config Resolution FPS
    U7600-1.2@1.6
    HD4670-1GB x1 1.0 W7/DX9
    1280x800 34.7
    1280x102432.5
    1680x105027.6
    1920x108025.3
    Performance Scaling with resolution
    • Purchase an expressCard 2.0-equipped Sandy Bridge notebook, with it's x1 2.0 providing ~60% faster performance than x1 1.0.
    • Petition ATI/AMD to get full duplex performance on Intel chipsets without needing the x1E tweak.
    • Petition NVIDIA to unlock the Optimus performance tweak with x2/x4 links and with systems that do not have an iGPU for their primary bootup video as requested.
    • Try 3rd-party tweaked drivers. Realistically only giving < 10% better performance.
    • Link two x1 ExpressCard and/or mPCIe ports to get a x2 link, like BPlus' PE4H does.
    • If system supports it, overclock the PCIe bus using setfsb. Eg: 100->105 yields a 3.3% RE5 FPS increase.
    • Minimize PCIe traffic by disabling hypermemory/turbomemory and video card's HDMI soundcard.
    • Further minimize PCIe traffic by reducing color depth from 32-bit to 16-bit giving up to 72% performance improvement. See details.
    • Reduce all possible PCI bus communications shown to improve performance.
    • Get rid of NVidia x1.Opt microstuttering by setting a FPS limit with 300.x drivers here (Khenglish)
    • Apply game-specific tweaks like the SCII one here from apac.

    6. (Performance) Can my system do a PE4H x2 or x4 link as shown in PCIe Scaling Analysis?
    BPlus' PE4H has made provision to allow compatible 2xmPCIe ports, or mPCIe+expresscard ports to be combined to form a x2 port. To identify what is possible, find your Intel I/O chipset below to identify what ports can be combined to create a x2 or x4 width link

    *=switches [port1+2] into x2 mode. ^switches [port5+6] into x2 as well. An Intel limitation. NA=feature locked into BIOS flash descriptor
    Other combinations to get x2/x4 ports such as p1+3, p2+4 do not work! In example above, the 2510P can't do a x2 link since it has only the 1 physical mPCIe slot. You'll notice on the 2510P port1 is enabled - it's a root port that must be enabled for *any* port to work. 2510P's port1 is not physically connected. The DV2000 has ExpressCard=port1, mPCIe=port3, mPCIe=port4. So the DV2000 can do a x2 link using the 2 mPCIe slots as port3+4.
    The best way to identify your port layout is to insert a ExpressCard e-sata card and see what port it reports as being on, then checking too the wifi card. If have multiple mPCIe slots, worth swapping the wifi aiming for a [port1+2], [port3+4], [port5+6] or [port7+8] setup.
    NOTE: port1 is the root port and must be enabled for any of the ports to work. On quite a few systems this is just a phantom port with no electrical connections to a mPCIe or expresscard slot.
    Where can I find schematics of my systemboard to find port layout? Try laptopdesktopschematic, lqv77, GSM-extreme, and/or notebookschematic. Searching on the web may also yield more information.
    Related: How do I enable port1-port6 if bios has disabled them? Use eGPU Setup's 'iport on'. Related: How do I setup a x2 1.0 link? Use eGPU Setup's 'iport x2 [port]'.

    7. (Performance) What recommended candidate notebooks should I buy for best performance?
    Quick answer - choose any from this list: Example ExpressCard equipped SB systems suitable to attach an eGPU.
    Performance will be determined by PCIe bandwidth available, which is ranked from highest->lowest below and and if the notebook has Intel 4500MHD, HD, HD3000, HD4000 iGPU primary graphics so is NVIDIA Optimus capable.
    1. PCIe 2.0 series-6 chipsets providing equivalent to x2 1.0 bandwidth. Current ATI cards appears to be running crippled half-duplex links on Intel PCIe ports. Compare HD5750@x2 and HD5770@x2E and techpowerup's HD5870 x1 2.0 results. Series-6 chipsets might deliver x1 2.0 *full duplex* with ATI cards, or 4 times more bandwidth than what ATI cards appear to be getting on series-5 or older chipsets. 2. a Intel-chipset system that allows a x2 link by ganging [port1+2], [port3+4], [port5+6], [port7+8] using mPCIe+expresscard or mPCIe+mPCIe slots. Note: using a x2 port3 affects port1/port2 operation since it sets port1 into x2 mode. 3. series-4 or older Intel-chipset system that allows a x1E link off an odd numbered port for ATI cards OR an AMD/NVIDIA chipset that provides full x1 1.0 performance using an ATI card
    Intel 4500MHD, HD, HD3000 or HD4000 iGPU allows NVIDIA Optimus superior performance with latest Fermi NVIDIA cards.

    8. (Performance) Can I do a SLI/Crossfire implementation combining mPCIe+mPCIe or EC+mPCIe ports?
    timohour found this is not possible here.

    9. (Performance) How could manufacturers make eGPU x2 2.0 notebooks?
    UPDATE 2-24-2011 The Apple+Intel Thunderbolt port is a x4 2.0 external PCIe port, though looks like will be uprated to x4 3.0. Perfect for high performance eGPU purposes.
    As it appears there is no desire to make an external graphics port standard it can do be done effectively another way. All that is required are 12-18.4" notebooks with:
    • 2x34mm Intel ExpressCard 2.0 ports electrically configured as either [port1+2] or [port5+6]. Doable with series-6 chipsets.
    • switchable HDMI input back into the internal LCD to route the external GPU output to like the Clevo X8100 provides.
    In addition provide a bios that
    • can set [port1+2] or [port5+6] as x2 width.
    • performs correct PCI allocation when attach a desktop eGPU to it.
    Such a notebook will be perfect for eGPU purposes, offering the equivalent of x4 1.0 in bandwidth. Performance then would be ~95% of when using a desktop eGPU with full x16 2.0 bandwidth.
    Only dilemma for manufacturers being such notebooks would become a serious competitor to bulky expensive gaming notebooks that have poor battery life.
    10. My system has switchable graphics. Can I still do install a DIY eGPU?
    Yes you can. Setup 1.x's (Video card->Hybrid Graphics.dedicated=off) allows the dedicated graphics component to be completely disabled on Series-5 or older chipsets, freeing up 32-bit resources to host the desktop eGPU. If your primary video card is a Intel 4500MHD, HD, HD3000 or HD4000 then can even do a x1.Opt NVIDIA setup.

    11. My Villagetronic ViDock product isn't working. Can you help?
    Consider then opening a support ticket on Villagetronic's support page or asking for help on the Villagetronic community Facebook page. If Villagetronic can't provide a working solution then consider obtaining a refund from them.

    12. Can I solder my own adapter to host an eGPU instead of buying one from HIT, BPlus, Redtrontech, Villagetronic?
    Yes you can, especially if you have more time for soldering than money for a pre-manufacturered adapter. See examples how to make one by ']acyd (Russian)&, sonny_mv, blackett &.

    13. What do I need to run the fastest x1.2Opt link shown in the implementations?
    The following ingredients are required for a x1.2Opt link:
    1. A Series-6 system (Sandy Bridge) or Series-7 (Ivy Bridge) notebook with an expresscard slot^.
    2. A PCIe 2.0 compliant PE4L-EC060A 2.1b
    3. A NVIDIA Fermi or Kepler class video card. A s/h GTX460-1GB OC edition with 336 cores being great bang-per-buck.
    4. A power supply to drive your video card. A 203W Xbox 360 power supply a good to mod for < 198W video cards and providing portability. Or any ATX PSU with sufficient power on the 12V rail if don't need portability.
    5. Latest NVIDIA desktop video drivers. They provide the ability to drive the internal LCD upon detecting a Intel 4500MHD, HD, HD3000 or HD4000 iGPU. When the iGPU and x1 link is found, PCIe compression engages gaining anywhere from 20-333% better performance over a x1 2.0 link without compression.
    ^ a PE4L-PM3N 2.1 will be released so could use a less convenient mPCIe slot instead of the ExpressCard slot. Useful for systems like a Sony Z2 which don't have an expresscard slot

    1. What parts do I need and where can I buy them?
    [​IMG] [​IMG] [​IMG] [​IMG] [​IMG] Above: Fujitsu S710 eGPU implementation - US$85 PE4H-EC2C(comes with SWEX and PCIEMM-030) plus a HD5770+ATX PSU
    1. The ExpressCard or mPCIe to PCIe adapter. See related 2. Can my system use PE4H's x2 1.0.. in FAQ. You'll need the US$92-shipped PE4L 2.1 if you want the faster PCIe 2.0 performance on Sandy/Ivy Bridge Series-6/7 notebooks. The linked units below are PCIe 1.1 which is the maximum speed available on Series-5 (1st gen i-cores) or older chipsets.

US customers can purchase from HIT as highlighted. 1 buying the PE4H means you can acquire parts later to do a x2 link Recommend: an extra US$6-shipped DX mini hdmi cable. 2 users requiring a replacement part for the setup to work.
    Which one? PE4L or PE4H?
    PE4H has a sturdier base, can allow a 15-19V DC jack input and up to x4 connectivity. PE4L is not as sturdy but is smaller and lighter. It can allow a 12V DC jack input and x1-only connectivty.
    Amfeltec has a cheaper x1 1.0 mPCIe kit starting at US$29 here.
    2. A video card of your choice
    Review next item 2. Which video card do you recommend for best performance on my system? to determine if an ATI or NVIDIA solution will perform better on your setup.
    3. A suitable power supply to drive your video card
    Can determine how much power you require by counting the number of 6 or 8-pin PCIe connectors on your video card. The total power required to drive it will then be:
    75W for the slot1 + 75W for each 6-pin PCIe connector + 150W for each 8-pin PCIe connector
    1: Can be supplied using either the DC or the floppy molex jack. The DC jack differs on the PE4L and PE4H: PE4L takes 12V input, PE4H takes 15-20V (regulated) > 84W. The AC adapter must have a 2.5mm/5.5mm or 2.5mm/5mm barrel end to use the DC jack. The floppy molex input is used with an ATX PSU..
    Power can be supplied by using either an ATX PSU or AC adapters. Can also split AC adapter power to supply a PCIe connector as shown here.
    Refer also to ithildin's and serialk11r's PSU recomendations for details on how to read the PSU labelling. 430W may actually mean it only supplies 168W for our purposes!!
    2. Which video card do you recommend for best performance on my system?
    This will be determined by your chipset, if additional ports available for x2 linkage and whether you have Intel 4500MHD, HD, HD3000 or HD4000 graphics. The matrix below makes recommendations based on the system chipset with:
    -LIME recommend NVIDIA Fermi (GT430 or better) solution for best performance
    -RED recommend ATI HD5750 or better solution for best performance
    -CYAN choose based on preferred performance bias: DX9 (ATI HD5750 or better) or DX10/DX11 (NVIDIA Fermi). Thunderbolt users may still elect NVIDIA Optimus solution (if have an iGPU) as then can then render the image to the internal LCD. Refer to Performance: ATI/AMD versus NVIDIA benchmark results to help you decide. If not sure then suggest a NVIDIA Fermi solution which on balance gives better overall performance and has the option of x1.Opt with the right notebook. Note: if the NVIDIA x1.Opt driver was unlocked to allow primary video cards other than Intel 4500MHD/HD/HD3000/HD4000 plus it engaged with x2 links then I would recommend only NVIDIA solutions.

    3 x1E tweak uses a x2 link on port1, 3 or 5 with a single lane for 15-30% more perf (ATI/non-Fermi NVIDIA only). 4 x2E tweak use two lanes of a x4 link, [port1+2] as EC+mPCIe or mPCIe+mPCIe for 30-60% more perf (ATI/non-Fermi NVIDIA only). 5 x2=combining expresscard+mPCIe or mPCIe+mPCIe slots [p1+2], [p3+4], [p5+6] or [p7+8]; x4=[p1+2+3+4] or [p5+6+7+8]. 6 Series-6/7: Only for Thunderbolt-equipped notebooks. Trying to combine mPCIe+ExpressCard slots no longer possible as Intel now locking the link width in the flash descriptor. Requires advanced bios hacking to configure x2 link, cannot be done using Setup 1.x. 7 This would only be possible if the ExpressCard slot was wired to the north bridge which runs PCIe 3.0. All ExpressCard slots so far have been using the south bridge which is currently limited to PCIe 2.0. So we can say this is not possible. ? Don't know if non-Intel chipsets can do x2 links.

    If going ATI/AMD, recommend a HD5xxx/HD6xxx series card over a HD4xxx series due to their more efficient usage of PCIe bandwidth. Benchmarks would predict a HD5670 to outperform a HD4870.
    Avoid twin-GPU cards like a HD6970/GTX590 since they require 2x256MB PCIe space windows which might be difficult to accomodate.
    Examples based on power consumption requirements
    • 12V/75W adapter: HD5670, unplugged HD5750, NVIDIA GT430.
    • 12v/80w: specific HD5750 units. See comment here, implemented here.
    • 12V/120W: GTS450 described here using DC adapter that is shared between notebook and eGPU
    • 12V/203W Xbox 360 PSU: GTX460
    • ATX PSU: AMD HD68xx, NVIDIA GTX4xx/GTX5xx

    3. Is it possible to get an enclosure?
    A good thread to see some professional designed enclosures is at redback79's DIY enclosure project. In addition, BPlus offer DIY Box enclosure for US$60 that uncannily resembles a US$10 acrylic aquarium with plastic posts and some hole cutouts. There are others for sale or examples to build on your own, for example:
    Elmopol's XB360, Joss27's 5.25" SCSI box, Wolf Tohsaka's Livebox Mini, timohour's floppy holder, fr0z3n's carry-it, Fujian stand/enclosure, airzone (1U), Kallogan (192W AC), hlgr, aodioxp, SimoxTav, #1, sprtnbsblplya, Agent9, Lurifax (mini ITX), kizwan (Aero QX2000, mITX), the endless +XB360 PSU, max_headroom and Oddious (1U), lightnica (JuiceBox), pengy_666's 5.25" drive enclosure, 12V/120W "portable", pimped-up (xb360) which is similar to Building an eGPU (CUDA).
    4. What software setup do I need to make this work?
    You just need video card drivers for your chosen operating system. This will be available for download from www.amd.com (ATI/AMD) or www.nvidia.com (NVIDIA).
    Or custom NVIDIA Optimus, DNA drivers for ATI/AMD cards are available too.
    DIY eGPU Setup 1.x may also be required if encounter error 12: cannot allocate resources in Device Manager or have specific port requirements such as x1E, x2, x2E link widths or mPCIe antiwhitelisting. Click link for more details.

    5. I'm using an ATX power supply to power my graphics card. How do I switch it on?
    PE4H is supplied with a SWEX, a small switched circuitboard used to power on/off the ATX PSU. The alternative is do the paperclip trick to switch on the PSU.

    6. What cable connects PE4L/PE4H to EC2C/PM3N and is it replaceable?
    It's a mini_hdmi to mini_hdmi cable. Cheapest replacement being $US6-shipped DX 1.5m cable confirmed to work here.

    7. [mPCIe] What can I do to make it easier to connect the mini hdmi cable to the PM3N?
    Could consider a cutout hole on the bottom plastic cover to provide an access point if you otherwise need to remove covers to get to it. OR could permanently attach PM3N internally, threading through a flat mini HDMI cable + adapter. The adapter would go on the PE4H/PE4L end. The bulb of the cable can be dremelled to sit more flush as shown here.

    8. Why does my video card fail with an error 12: cannot allocate resources in Device Manager? See Troubleshooting FAQ - Q3.

    Key
    RED - a x2 1.0 link using a PE4H linking expresscard+mPCIe or mPCIe+mPCIe. All others are x1 1.0.
    ORANGE - appears to have port layout to do a high-performance x2 1.0 setup using either [port1+2], [port3+4], [port5+6], [port7+8]
    GREEN - video card that requires only a compact 12v/80w AC adapter for power. No external ATX PSU needed.
    All tested at 1280x800 except 3dmark06 which used the default 1280x1024 and those marked *
    x1.1: x1 2.0 (5GT/s) capable system running at x1 1.0 (2.5GT/s) if PCIe 2.0 DIY eGPU hardware is used.
    x1.Opt: system with Intel 4500MHD, HD, HD3000 or HD4000 iGPU primary graphics using NVIDIA Optimus for higher performance + internal LCD mode.
    x2.Opt = x2 link, Intel HD graphics, Optimus driver, but Optimus performance tweak only engages on x1 link as found.
    x1E/x2E: apply x1E tweak to ATI cards and older NVIDIA cards on series-4 or older Intel chipsets to get ~full duplex performance

    1 Requires DIY eGPU Setup 1.x to overcome 12: cannot allocate resources and/or to set specific port requirements.

    2 EC/mPCIe: ExpressCard/mPCIe slot used by a EC2C/PM3N product. Port layout required for x1E/x2/x2E/x4 mode. Intel chipsets' require port1 enabled for other ports to work so port1 may not be a physical mPCIe/EC slot.


    Systems incapable of running 4GB+ setups for reasons as explained. These will require a DSDT override to work.
    1. 41st-gen i-core and core2Duo Dell Latitude have TOLUD=3.5GB.
    2. MSI CRx20
    3. Lenovo T420 doesn't work unless use bios 1.15 as explained.
    4. Sony E-Series i-core has an unusual reserved system device. Only a NVIDIA card can fit around it in 32-bit space.
    5. Dell XPS 1530M has TOLUD=3.5GB as explained.
    Systems capable of a higher performance x4 or x2 PCIe links

    The Orange and Red systems shown in the above table. Also: Systems not capable of a higher performance x2 1.0 PCIe link shown in black in the table above, as well as:
    Acer 4741G(mPCIe), 5820TG(mPCIe), 8935G, Asus F3JC, G60, N61JQ, Dell Vostro_3400, Inspiron_1545*, HP DV3-2232tx, DV6-2119TX, DV7-3110TX, Lenovo G560, x201s, MSI A620x/Cx620, U200 (mPCIe), Samsung R580, Sony VGNNW29GF, Toshiba A300*, A500-026, A500-031, M305, P500-01g, R700, U500-00k.

    * = can do a x1E tweak, relevant to only ATI cards and older NVIDIA cards, since the ExpressCard slot is an odd numbered port with nothing occupying the next port and is a series-4 or older Intel chipset.

    Interesting. The question I have is whether anyone has seen any rumors/info on when we'll start seeing ExpressCard 2.0 in notebooks from manufacturers? I get that you can have better by speeds using the mini-pcie, but I wouldn't want to crack open my laptop and remove the wireless card every time I wanted to play a game.

    Lenovo has some new T-series Thinkpads coming out in early 2010 - wonder if they'll be ExpressCard 2.0?

    think the performance is cpu limited? or is the 1x express card limiting it. i have a 2.53ghz

    It's a 256MB window into the video card's 256/512MB/1GB VRAM.

    Yes. mPCIe or expressport both work and both do the same bios bootup mode if HD4670 is connected on powerup. Notice too the expressport is port1 and the mPCIe is port4 as shown here.

    The cpu is the minor culprit in limiting the performance. x1 1.0 expresscard/mPCIe being the greater bottleneck as we can see by the PCI-E Scaling Analysis. A HD3850-256MB, which would perform slightly worse in a normal desktop system than a HD4670, gets a RE5 score of 57FPS at x2 1.0 mode, or 34FPS in x1.0 mode. The CPU too is limiting the performance as you can see I'm capped at ~U9400 levels, but the 3dmark/RE5 scores have increased as cpu power increases from ~n270->~U3500->U7600@1.5(OC)->~U9400 levels so I'd expect that to continue slightly.

    I guess it's a question of priorities. x2 1.0 giving quite an impressive performance increase as shown by the PCI-E Scaling Analysis. I'd personally go the x2 1.0 link mode if my system supports it and an inexpensive USB Wifi stick.

    Just wondering I have a slot for a mini tv card next to the mini pcie slot currently used for wireless. Can that be used for x2 1.0 link or is it a different socket?

    for a system that just sits on your desk, sure
    but for a laptop you take with you in your backpack/briefcase every day and work on for 10 hours in a business day?
