DIY eGPU experiences

[DrizzitT]

Just installed eGPU on my X220

X220
i7 2620M
8GB ram
GTX 560 Ti
Using Verde 295.73 drivers
Most recent Bios
PE4L 2.1b @ 1.2 opt

3DMark06: 18727-18890 (depends on run)
RE5 DX9: 154.8 FPS (no AA/etc... not sure what needed to be turned on; default, variable)

Plays Diablo 3 at 1080P pretty well (everything maxed), was getting some stuttering but I believe that was due to a ethernet driver. There are some slowdowns/low FPS areas though. I'll report back after I try it out with the current setup.

Installation was very simple. No longer need to hotplug. Turn GPU on, plug into expresscard slot, power computer on. Install drivers, restart, done. Hotplugging caused GPU to switch to max fan and did not recognize.

To get my internal LCD runs with eGPU. Does the GPU has to be Nvidia's Fermi type of graphic cards?
Since I purchase a EVGA GeForce GTS 450 1GB 01G-P3-1452-TR PCI Express 2.0 Video Graphics Card, I am thinking if I have to refund it and get a Fermi one like: EVGA nVidia GeForce Fermi GTS450 GTS 450 1GB PCI-E Video Card 01G-P3-1351-KR

The another question is that, what kind of AC adapter I need to purchase (It said a 12V/120W AC adapter works fine) but what kind of barrel size that can plug into a PE4H-PM3N?

Im a computer noob """

The 450 GTS you have is already a Fermi.

Thanks men, you know which is the difference between PE4L 2.1b+ and 2.1a???

2.1a was broken, soldering was necessary.

So been playing around with 3dmark, and my modded shuttle 300w psu, and some preliminary overclocks on the gtx680

new scores

3Dmark11 external screen - 8135 overall l, 8517 gpu portion
3Dmark11 internal screen - 7421 overall, 7933 gpu portion

3Dmark06 external screen - 23717 overall
3Dmark06 internal screen - 20514 overall

The results are surpising to me, not near as bad of a performance hit using the interal LCD as I had imagined.

Everything is very smooth so far (now that I've switched OS's).. although I have yet to actually game on it.. that will be soon enough I suspect.

Thanks again everyone for the help and support.. this forum is awesome!

Can a 12V/120W AC adapter (2.5x5.5) works on PE4H?

hi guys - quick question, I'm considering a Lenovo X230T and buying a eGPU solution. I assume ViDock are the way to go from reading as many pages of this thread as I could but if you could answer me the following I would appreciate it:

1) I'm a little confused about the criteria for running it on the internal screen. I do a lot of consulting so I'll be staying in hotels without an external screen - what do I need to ensure it runs on internal? I have seen references to Fermi being required? If someone could explain to me what I need and the reasons behind it that would be fantabulous.

2) I've been a bit hung up on the Expresscard solution VS the thunderbolt solution. Clearly the Thunderbolt has the faster bandwidth but assuming the latest NVidia card (for example a 680GTX) are we able to run it on internal screen and will it bottleneck on expresscard?

3) The express card slot on most laptops goes right under the left wrist pad where you put your wrist when gaming - does the card get hot? For me there is nothing worse than gaming on a red hot palm rest (I don't like external keyboards sucks to be me...)

Cheers guys

I know it's been mentioned a while back that HIT was going to carry the 2.1b of the PE4L kit soon, but their website still states the older 1.5 so I was wondering if anyone had an update on this? I was holding off, but now it looks like I'll need to go the eGPU route for Diablo 3 on my Lenovo W520...

I spoke to them Friday and they said they expected them in early next week.

I spoke to them as well and got the same response; however, the site says May 25th, so who knows.

Hopefully my order will finally get to me in the coming week. I'll be sure to post here on how it goes.

Hmm..
I forgot to save my purchased eGPU setup 1.X... and now I cannot re download it. It keeps telling me Download ID invalid.

Is it normal ?

Edit : stupid HIT download policy...
