DIY eGPU experiences

[Cabaal]

little OC. first result, reference. two lasts, with mV moved from 1037 to 1075.

external: (900/2100 vs 950/2200 vs 1000/2300)

3dm11: 4194 vs 4395 vs 4604

------------------------
vantage doesn't "feel" OC, Heaven breaks down always on 23 benchmark part, beside what OC was used.

Comparing it to my GTX 560 TI 448 results, there seems to be a massive space for OCing my card. I got 4.919 3dmarks at stock clocks (only 750 MHz core clock!). Some reports indicate, that the 448 is able to run even 1.000 MHz at core. So there should be a massive boost in performance.
Seems like the 448 is well worth over a "stock" 560.

Hi

it`s working with an external screen and 3 gb of ram. I didn`t get more to work nor did anyone I know (until now I know of 3 L520 users including me).
Same problem with internal screen, not working yet but I`m working on that.
If you choose a L520 with Sandry Bridge and a PE4L 2.1 than you will have expresscard 2.0.
I`m playing BF3 on high with 1680*1050 with a GTX 560 Ti. I have no Idea how much faster the gpu would be in a Desktop PC. In 3dmark06 I got a value around 16200 (don`t remember the exact value).
If you have more question just ask.

Hey,

thanks for the fast reply!
That are good news, but i'am wondering about the 3gb of ram... Are there any issuses when using 4gb or more? 3gb are not very useable..
Also i'am wondering why i should buy the PE4L? Are there no differences between x1 and x16 PE4H? And can i plug a x16-card in x1-slot? It seems to me that it doesent fit ..but correct me please

And what is about hot-plugging the expresscard? Does it work?

Thanks for the advice nando, i will most likely just settle for getting an inexpensive external monitor and try to free up some space or might just wall mount it.The SB notebooks are out of my budget and even if i did get one its gonna be too much of a hassle selling my x200.Also one thing i would like to mention that i didnt previously is when i connected it to the external monitor that i borrowed, although the fps was much better i got the BSOD 3-4 mins into playing the game and this happened twice, what is the cause of it? and is there anyway to fix this? Thanks again

Didn`t have any problems with 3 gb ram but played only lol and bf3 until now. More than 3 isn`t working. Perhaps it works with Setup1.x, i will try it as soon as my credit card arrives (takes some weeks). DSDT override is not working for me because it results in a BSOD.
You can only hotplug the egpu, both booting with it and f8--> resuming boot isn`t working.
As far as I know the PE4H version for PCI express 2.0 isn`t available yet, so your only possibility is PE4l 2.1 if you want 2.0.

I sent an email to Sonnet regarding the Echo Express PCIe with Thunderbolt release, and they are hoping for a May release. So close yet so far...

Ok. that Sounds great. But i really need more than 3gb ram for work so i have a last question did you try out 4gb or did you just got 3gb installed and its working with it?
i have now read something about the PE4L 2.1b but i cant find a reseller? i can only purchase the 2.1a which seems to be buggy with gpus..

I tried 2, 3, 4 and 8 gb, only 2 and 3 worked.

Hi Kizwan,

i have repeated the steps a couple of times but it still aint working.
Maybe you could help take a look at the following screen-shots if
i have made any mistakes.

Thanks Again

Hi Kizwan,

Is the above correct?
Was the DSDT correctly executed?

Thanks

Hmm thats really bad.. which error occur when you install more than 3gb?

A little bit of an update on my old score: I have a HP 2740p (i5 520M) in my possession for the time being, and I swapped in the SSD from my 2730p, installed new drivers and then set it up with my eGPU; With the old 266.58 Nvidia Drivers (yet what I had found to be the most reliable drivers) here is the 3D mark 06 score on an external HDMI screen NVIDIA GeForce GTX 460 video card benchmark result - Intel Core i5-520M Processor,Hewlett-Packard 7007 score: 12137 3DMarks 12137!


Its not much higher than the 10320 form my 2730p, but I found in some very limited testing that it is in fact noticeably smoother in games (and in the benchmark) than with the 2730p, it seems mostly because of the better CPU


EDIT: Got it working internally; it got 9932 http://3dmark.com/3dm06/16580797

Will now try a newer driver and see if it works or not...
