DIY eGPU experiences

[ithildin]

See my benchmark results comparing HD5750@x1 versus GTX465@x1 where the GTX465 is vastly superior in all tests except the 3dmark06 which is outdated and not worth looking at anyway. My card too can run as a GTX470, similar to overclocking the GTX460, which will give another 10-20% better performance. GTX470 benchmarks will be added once I've completed full GTX465 benchmarking.

Yep, excellent stuff. I have to say that I am not convinced that 3dmark06 is irrelevant as a benchmark. I also saw significant differences in DX9 between the HD5750 and GTX 465 on BF: Bad Company 2 (~18 FPS AVG). Regardless of DirectX, the game on the GTX 465 stuttered for 5-10s on each map load before the framerate stabilized. I also saw that the performance differences were not as noticeable on RE5 in DX9 but that could be due to code optimization. Still, the 3dmark06 score for the GTX 465 at full x16 2.0 blows the HD5770 out of the water (20k vs 16k) so it doesn't seem like an issue of the GPU per se, it only seems apply to DIY Vidock situations...
Anyway, I'll keep an eye out for the same issue on the GTX 460.

Hi,

anyone having problem after updating ati driver to the latest 10.6 driver?
i have...i nv experienced this problem before but let me explain...i downloaded the new 10.6 and updated it, restarted it...everything is fine..

then i reformatted my bootdisk, and restarted it and go into bootdisk to start the vidock, everything is fine, was able to boot into windows...but the problem is, nothing comes out from the external monitor....

then i went to the device manager, click resources and at the "Resource Settings: it says 'This device isn't using any resources because it has a problem'"

so anyone can help me?

Thanks.

Your system is x1E capable. Try x1E to open up the performance more or go a GTX460

I will, believe me, as soon as I understand how to do it. I'm checking your instructions for PNP system, but I cannot figure out point 3. Downloaded Baredit, but I don't know what RCBA+224h is and where I should wirte 0xA2(port3). If you will have time, could you write more details so an inexpert guy like me could also understand? I would appreciate it!
One more question, do I need to unplug the wifi card from slot 1 to achive x1E?

Thanks!

Absolutely. Especially if you have a Thinkpad that has the expresscard slot as port4 where the x1E tweak cannot be applied. Consider:

- the GTX460 can be overclocked to deliver GTX470 performance.

are you sure, that a thinkpad (t400) can not be used ind x1e or even "x2" mode?

Use DIY ViDock Setup devel version posted a few posts back as the easiest solution. Here you show use that expresscard slot is port3. So you'd be putting port3 into x2 mode which ports port 1 into x2 mode as well, effectively making the wifi on port not functional. You might/might not need to remove the wifi card as it would be seen as the second lane of the lan controller on port1.

I believe you'd need to use the turbo memory mPCIe slot (port3) + expresscard slot (port4) to do x2. So could consider it then with a HD5770 card. If you want a single-cable solution that uses expresscard port4 then consider a GTX460 for it's better x1 1.0 performance than a HD5770.

That is what I tried first, but it looked more complicated than the PNP version, which I almost understand, I just need to know how to identify where to disable port3 and 4 and which address shall I change and to what. I guess the rest is easy.

Perhaps a screenshot of Baredit to each step (especially point 3) of PNP system would help me...

ok additional note is that, i do not have the code 12 error now if i hot plug the vidock when windows 7(i upgrade to win 7 home premium from vista home premium) is running....

i checked the 5750 properties and in the resource it only says "Resource Settings: it says 'This device isn't using any resources because it has a problem'"

oh also i tried if i was able to PNP by sleeping the computer and plug the vidock in and resume but all it gives is the "Resource Settings: it says 'This device isn't using any resources because it has a problem'"

hmm....still cant be PNP like how i wish it could be.....oh well at least upgrading to win 7 makes my com looks awesome and much simpler...

i am sorry for a lazy search through out the forum..but can anyone help me by showing a link or a simple explaination or picture about the implementation of PE4L with ATX PSU..to any GPU..maybe 5770..or any..please..nando or who..the thread have more than 100 pages..i am too tired to read all the messages..sorry..! i am a rookie..

Ok, this is what I did:

Step 1: My RCBA=FED1C001

Step 2: I added 3418 to FED1C001 = FED1F418, so I switched 17(port2), 18(port3) and 19(port4) off

Step 3: I found FED1C001+224 = FED1C224 and changed to A2

Step 4: I switched on port2, port3, port4 and when I push write it freezes. Only switch on/off bottom is working, so I have to reboot.

What did I do wrong?
