INTRODUCTION >>>

This thread is dedicated to the practical application of these products to attach a desktop external Graphics Processing Unit to a notebook via a expresscard, mPCIe slot, or Thunderbolt port. Ideally, this thread is a place for users to share installation and performance details for others to duplicate or reference.

If you run Windows 7 exclusively, it is very easy to enable the eGPU without a reboot. Just standby the system, plug in the PE4L, resume, Windows 7 detects the desktop GPU and reverts back to how you have your desktop setup (eg: HD5750 as primary or extended display). Easy.

The performance difference b/w the onboard 4500MHD/HD3000 and an attached desktop eGPU is staggering. The Inspiron 1440 using the x1E tweak saw 3dmark06 go from 866 to 9551. RE5 benchmark went from an unplayable 4.1FPS to a very playabe 60.9FPS. The HP 2560P's x1.2Opt link saw 3dmark06 increase over 4 times to 18340 and RE5 gave an average of 148.3FPS(!!), even allowing the internal LCD to be driven by the eGPU.

PRE PURCHASE FAQ >>>

1. How does a DIY eGPU differ from a Villagetronic ViDock3/4?

Spoiler :

The Villagetronic ViDock 3/4 is in essence a PE4L packaged together in nice chassis with a PSU. eGPU's flexibility makes it imho an overall better solution over ViDock 3/4. Consider the DIY eGPU's advantages:

• significantly cheaper: US$77-delivered PE4L versus US$215-delivered for the ViDock3. A GTX460-768MB eGPU setup works out to be US$230 cheaper, or half the cost of an equivalent Vidock4+ GTX460 setup. Costs can be reduced further by recycling or salvaging power supplies with savings put towards a higher grade gpu, a cpu upgrade OR even towards a system upgrade that's a better eGPU candidate.
  
  
• less losses to try: can try and if unsatisfied, can resell on ebay with minimal losses. Villagetronic's 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 only caters to 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.
  
  
• can add PSU to match your video card.
  
  
• has inexpensive eGPU enclosure examples if you want an enclosure.
  
  
• unrestricted video card sizes or cooling space: Not limited by chassis package dimensions.
  
  
• PE4H allows desktop video card to be hosted externally and shared b/w notebook and desktop (@x4 1.0 speed via HP4A).
  
  
• extensive user submitted experiences to replicate and set realistic performance expectations.
  
  
• uses a replacable US$6-delivered mini HDMI interconnect cable
  
  
• a NBR creation: came from a global community to serve a global community

2. How can I check if my notebook is compatible with an eGPU?

Spoiler :

If the system has a dGPU then ensure it's 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.



Pretty much any notebook can be eGPU compatible if it's run with 2GB of RAM. 95% are OK with 3GB of RAM. It's only if it runs 4GB or more that there needs to be particular attention paid to free pci-e configuration space to host it, which can be checked by:




(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 (anything after 2007) to be eGPU compatible when used with Windows 7 and the latest iGPU/dGPU/eGPU drivers with up to 48GB of RAM installed. So the DSDT override solution eliminates the restrictions listed below.

• if the system has a switchable iGPU+ATIAMD dGPU or switchable iGPU+NVidia Optimus dGPU configuration then can use Setup 1.x to disable the dGPU component to allow a eGPU to use it's pci-e space. This also works with all Intel chipset systems with NVidia or ATiAMD switchable graphics with the exception that Series-6 AMD switchable graphics hasn't been confirmed to be allow such disabling as explained.
  
  
  
• if the system has only a dGPU or iGPU (not switchable) then check the system's TOLUD+Large Memory to ensure there will be no issues running 4GB+. Check in Device Manager. Set View to "Resources by connection" & expand the Memory tree like shown.
  
  
  
  If you have the somewhat rare large memory memory entry then the eGPU can be hosted in 36-bit pci-e space.
  
  If not, as is far more common, then the eGPU will be hosted in 32-bit pci-e space where you'll require TOLUD being 3.25GB or less. Identify this by looking for the first PCI bus entry with a 8 digit memory address. Compare it with table below (thanks Kizwan!):
  
  
  
  

  First PCI bus with 8 digits memory address	TOLUD
  E0000000	3.5GB
  D0000000	3.25GB
  C0000000	3GB
  B0000000	2.75GB
  A0000000	2.50GB

  
  
  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:
  
  
  
  • older C2D/Arrandale Dell Latitudes could only do a 3GB setup. A fix requested in REQ: bios mods to make Vostro/Latitude eGPU friendly.
    
    
    
  • Sandy Bridge Lenovo X & T series require the latest bios to do a 4GB+ setup. See Petition to fix TOLUD in newer BIOS files - Lenovo Community.
  
  
  There is some exception to this rule. We've found some systems have bios allocate systemboard devices that sit right in the middle of a "free" 32-bit 256MB pci-e block that cannot be relocated and prevents an eGPU from that space.
  
  
  
  To be absolutely sure an eGPU can be accomodated requires booting Setup 1.x and performing an 32-bit PCI "All" compaction, and seeing if you now have 256MB free shown in the Status window and confirming your system can chainload to Windows. If not, but you do have 128MB contiguous free space shown then consider that NVidia Fermi cards 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.
  
  
  
  If this is a bit too confusing then proceed to 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 and link here for analysis of your diagnostic output.

3. I don't have an ExpressCard slot. Can I still do use a eGPU?

Spoiler :

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?

Spoiler :

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?

Spoiler :

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 1280x1024 32.5 1680x1050 27.6 1920x1080 25.3

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.
• 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?

Spoiler :

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

Intel Chipset max# pci-e ports x2 link x4 link ICH7M 4 p1+2, p3+4* p1+2+3+4 ICH8M/ICH9M/HM55 6 p1+2, p3+4*, p5+6 Series-5 PM55/HM5x/QM57 8 p1+2, p3+4*, p5+6,p7+p8^ p1+2+3+4, p5+6+7+8 Series-6 HM6x, QM6x 8 NA NA

2510P's port

DV2000's port

*=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, notebookschematic and a general google search.

7. (Performance) What recommended candidate notebooks should I buy for best performance?

Spoiler :

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 pci-e 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?

Spoiler :

timohour found this is not possible here.

9. (Performance) How could manufacturers make eGPU x2 2.0 notebooks?

Spoiler :

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?

Spoiler :

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?

Spoiler :

I've never used a Villagetronic Vidock so am not familiar with their hardware. 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?

Spoiler :

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?

Spoiler :

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 pci-e 2.0 compliant PE4L-EC060A 2.1b

3. A NVidia Fermi or Keplar 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 XBOX360 a good to mod for 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, pci-e 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 in coming weeks 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. 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 available on Feb-20-2012 if want the faster pci-e 2.0 performance on a Sandy Bridge notebook. The linked units below are pci-e 1.1 which is the maximum speed available on Series-5 (1st gen i-cores) or older chipsets.

HIT: Harmonic Inversion Technology. A US distributor of BPlus' PE4H-EC2C/PE4L-EC2C with a cheaper base price, cheaper US$7 UPS shipping, plus are entitled to the Setup 1.x software (valued at US$25) upon your request as part of your purchase. It is recommended US customers purchase from HIT as highlighted.
¹ buying the PE4H means 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). Refer to Performance: ATI 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.

Left-to-right: slowest-to-fastest with NVIDIA x1.Opt and x2 delivering similiar performance

¹ provides full duplex performance equivalent to x1E on Intel chipsets.

² Optimus tweak engages only when Intel 4500MHD/HD/HD3000/HD4000 primary graphics AND x1 link is detected, improving performance by 20-333%. Provides ability for the internal LCD to render games running on the external GPU.

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].
⁶Series-6/7: Intel setting link width of in the flash descriptor. Requires advanced bios hacking to configure x2 link, cannot be done using Setup 1.x.
? Don't know if non-Intel chipsets can do x2 links.

If going ATI, 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 xbox360 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. There are some for sale or examples to build on your own. For example:

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?

Spoiler :

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 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?

Spoiler :

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?

Spoiler :

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?

Spoiler :

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). Awaiting new pci-e 2.0 DIY eGPU hardware.
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/mini_pci-e 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.

So...it worked via Mini PCIe on your dv2000?

[wilse]

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?

[tvdang7]

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.

[King of Interns]

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?

8600M vs s good desktop graphic card limited at 1x pci-e. not much of an improvement...
