DIY eGPU experiences

I own a Lenovo x220. Is it worth waiting for PE4L 2.1 or PE4H 3.0?

[Kallogan]

70 dollars yay !!!

I will sell my PE4H 2.0a at low price let's say 40 euros shipped, in case someone with previous gen laptops is interested. I'm from France.

How long cable will follow then?

How long do you want it to be? 45cm/1.5ft, 60cm/2ft, 100cm/3.3ft, 150cm/5ft, 200cm/6.6ft

Keplar 28nm GTX680 in Feb?

Maximum PC | Nvidia GeForce GTX 680 May Launch Ahead of Schedule tells us

... to counter AMD's recent Radeon HD 7000 series launch, Nvidia may opt to release its upcoming GeForce GTX 680 graphics card a month early.

Chinese website ChipHell.com is reporting that Nvidia is pulling back the GTX 680's release from March or April and will launch the card sometime in February. It's nothing more than a rumor at this point, though ChipHell forum member Napoleon has a pretty strong track record when it comes to leaked information, VR-Zone says

This is being discussed in Check this out - Nvidia GeForce GTX 680 May Launch Ahead of Schedule .

For me, PE3A x1 2.0.opt has no noticable bandwidth bottleneck with a GTX460 in Crysis2 or BFBC2, so I'd go for a PE4L 2.1 if I were in the market for one. Not to mention, I have my card hanging off my laptop and I think that's just fine :P As it is, 55 for a PE3A is already pretty steep, I don't see a need to go to a PE4H.

Does anyone have any ideas for my stability problem? MSI Afterburner isn't forcing full voltage like I want it to...

I have to report another working Setup

• Acer Aspire 3820TG
• switchable Intel HD / ATI 5650
• i5-450m
• 8 GB Ram
• PE4H 2.4a + PM3N
• EVGA GeForce GTX460 FPB
• psu: SilverStone SST-ST45SF (450W)
• enclosure: 3R SYSTEMS V20

Switching between eGPU & dGPU is done via BIOS-Mod, TOLUD is 0xA0000000 with dGPU disabled.

Still have some work left:

• solder full size mPCIe-slot (PM3N is currently in half size wifi slot)
• connect SWEX to power button
• wire internal usb hub & dvd drive

My first psu was too weak (+12V1: 14A, +12V2 - 10A), the silverstone has enough juice (36A). The GTX460 requires 24A.

Now it's time for some statistics

GTX460 @ x1.1Opt (stock clocks):

• fsb & pcie@133 - 13505@3dmark06, 93.1@re5(windowed)
• fsb & pcie@155 - 15479@3dmark06, 103.8@re5(windowed), 107.8@re5(fullscreen)

Nando,

I for one would like to go with the maximum length possible. I currently use the 1.5M cable from DX (Message - DealExtreme, and i use my EGPU exclusively via internal optimus. Frequently I play games in bed on my laptop tray with my egpu on the side, either on my night table or on the ground (if anyone is wondering how I can do this it's because I have the most compact and portable eGPU enclosure/power supply shown to date on this thread). It's pretty obvious that more people are going to be using the internal optimus mode considering the huge performance increase from the previous generation. For me, 1.5M is a minimum, the longer the better (2M would be great). For people who say this is too much length, it really isn't hard to neatly bunch up and tie any unused length. The fact is that the cable is NOT replaceable like the previous generation and having more length allows for more flexibility in other applications.

In an ideal world hwtools would create 2 versions, one with the shorter length and one with the longest length. I really hope this is the case. I am sure people such as myself who would like the longer version would be willing to pay a little more for this.

I don't think they can afford it, considering that they world for stock and no on ordering, making at least 4 different versions of the same adapter could bring too much extra costs. Anyway would be the best solution at all

30cm -> EC2C
30cm -> PM3N
100cm -> EC2C
100cm -> PM3N

Furthermore I'm happy to announce you that starting from tomorrow (hoping to receive the visit from the postman in time) I'll start making videos with my girlfriend's EOS 550d of popular games played with the eGPU solution (currently with PE4H rev 1.5, in future with newer adapter),
During my past weekend i made just the intro of the solution with Sony Vegas (available HERE for sneak peak). Post which games you would like to see tested and I'll try to accomplish the task (obviously for benchmark results I'll run in first place the games on the first page of the topic).

I want it to longer than the 30cm I got with my last kit, thats too short to place be able to place my box another place than next to the laptop so 50cm - 75cm

My ECslot turned out to be slot 2... so Slot 1&2 pair is now impossible. The only viable option for me would be slot 3&4, however I am unable to find slot 3 in my laptop.

The vids are a very welcome addition that will definitely get a highlight spot on the first page of this thread. The initial x1.1Opt vids good ones for users with Series-5 or older hardware to get a feel of true gaming performance. Future x1.2Opt results showing the smoother FPS the extra bandwidth provides.

I recall moral_hazard found he had a third mPCIe socket in his GT627 but was missing the connector. Would require someone to solder it on. The GX620 schematic does indicate 3 mPCIe sockets (which are pci-e). There are a maximum of 6 ports for your chipset. So if you can solder another socket on there then could do a [p3+4] x2 implementation using 2xPM3Ns. Ie:

GT627 port layout

port1: LAN
port2: expresscard
port3: <-- this must be the third mPCIe socket
port4: wifi mPCIe socket
port5: second mPCIe socket
port6: Firewire/SD controller

@all - we are seeing all sorts of desired cable lengths ranging from 30cm/1ft to 200cm/6.6ft. Not sure how that will pan out. It may well mean a longer cable such as 200cm/6.6ft is supplied where the user folds and ties it down to their required size.

I wish BPlus could figure a way of giving us back the socketted mHDMI connector so we could choose what cable best suits us.
