DIY eGPU experiences

[Gil3]

@Gil3,

Please post the PSU specification here.

I could not find the PSU specification of this power supplier ..

Can you recommend me for a good PSUs that cost a maximum 50$ ?
I want even less than 50$ if it is possible



Thanks

I'd recommend a modular power supply like this one.

RE: http://forum.notebookreview.com/gami...ml#post7734489

I just got it working!

I pulled one of my two 2GB memory sticks, turned everything back on and it works. (I suppose I somewhat owe nando a thank you for recommending pci compaction which got me thinking about memory.)

Sadly this means I'm now running single channel with 666MHz ram
EDIT: 800MHz, I was misreading the sticker on the ram. CPUZ confirms 800Mhz.

So some questions:
- should I be able to add a 1GB stick of ram and still have this work? (system memory would be 3GB which honestly is enough for me currently)
- how do I get rid of the "eGPU setup" boot option, since I don't need or benefit from it?

Are you sure you already try all combinations of PCI compaction? What is the TOLUD register set to (you should see it at the upper-right corner of the Setup 1.x screen)?

You can removed the "eGPU setup" boot option by following the instruction in Setup 1.x post.

TOPOWER Galaxis MX Series GAPS-500MX specification are:-

Feature	What I think?
Dual +12V Rails	Not recommended
PCI-Express Connector: 1 x 6-Pin, 1 x 6+2-Pin	OK
Output: +12V1@14A, +12V2@14A	12V * 14A = 168W: Power too low to power cards like HD5870, GTX560Ti, GTX460

I recommend getting Corsair CX500 V2 instead. Single 12V rail with 12V/34A (408W). Probably cost around USD 60.

This is what I was doing:

(iGPU + eGPU)

What is the TOLUD register set to (you should see it at the upper-right corner of the Setup 1.x screen)?

I'll put the RAM back in and check.

tolud@3.00GB

Tried compacting all pci devices: system froze
Tried compacting just egpu: code 43 after chainloading windows
Tried compacting just igpu: code 43 after chainloading windows
(Had previously tried egpu + igpu: code 43)

I'm not adverse to spending $15 on a 1GB stick of ram if you think it would work.

[kizwan]

With TOLUD 3GB, you should be able to use 4GB+ RAM. In your post, you did mentioned "hook everything up". Did you tried boot without eGPU connected & hotplugging the eGPU in windows?

[Leoben]

Just tried it now, screen went black for a second, then came back: code 43.

I have previously tried plugging it in with machine asleep, code 43 when I wake it up.

EDIT: I'm thinking my iGPU is causing the trouble. I believe it can use up to 1GB of system memory. I haven't seen anywhere where I can manually set this though (to say 256MB which is still more than it has processing power to properly utilize). [EDIT #2: I've checked the BIOS - no option.]

There is the Video cards->Initialize and Video cards->Save/Load dump features to eradicate error43. Ensure you are running the latest 275.33 Verde drivers + modded nvam.inf and the PCI reset delay slider on the PE4L 1.5/PE4H 2.4 is set to the 0 seconds position (not 7 or 15 seconds). Then proceed as follows:

1. Boot eGPU Setup 1.x with 2GB installed, run Setup 1.x, select to Video Cards->Save. If you are hotplugging after bios boot then need to select Video Cards->Save(Win) and follow instructions generated from within Windows.

2. Install 4GB of RAM. Boot Windows. Create a devcon with 4GB of system RAM installed:

\eGPU\eGPU-setup-mount
v:\devcon\mkdevcon

3. Boot eGPU Setup 1.x,
- select Video cards->Load to load the PCI space dump created when it was working with no error 43.
- perform 32-bit PCI compaction on the iGPU+eGPU.
- select startup.bat->edit, remove the 'call vidinit' since it might interfere with your load dump.
- select Apply config.Run startup.bat
- select Chainload mbr

If still get an error 43, then repeat steps in (3) above but use 32-bitA PCI compaction method instead.

It worked!

Do I have to do all these menu selections each time? (I'm guessing I don't need to edit startup.bat each time but what about all the other stuff?) Is there some way to do all this on boot with zero human input?

I take it this makes it so I can't hotplug my eGPU? I need to reboot windows when I connect it? (Not really a problem, my hybrid SSD makes reboots pretty fast.)

EDIT:
Never mind, I don't need to do ANY of this on reboot AND I can hot plug my eGPU. +1 Nando!
