DIY eGPU experiences

[User Retired 2]

Thanks for the response. That makes more sense than anything else I could come up with. So just to clarify, the GPU should be salvageable, but the PE4H needs replacement and an additional psu if I still want an egpu?

Yes. You could stil run a 12V AC adapter in via the floppy molex lead by attaching a 5.5 x 2.1mm CCTV DC Power Female Jack Connectors (10-Pack) - Free Shipping - DealExtreme to a molex ended cable. This would be your DC-to-molex lead. Using the floppy molex bypasses the 15~19V to 12V voltage regulator.

Could even use a higher power 120W adapter via a 1-to-2 Power Splitter Cable for CCTV Security System Camera (DC 12V) - Free Shipping - DealExtreme to drive a GTX550Ti/GTS450. Would need a second DC-to-molex lead to which you could attach a molex-to-pci-e lead going to the pci-e power on the video card.

Those DC splitter are interesting. I saw them a few days ago. I wonder though if they're meant to carry high current. A seller on ebay seemed to mean that those CCTV power cables were fused to 12V/2A max.

But maybe i misunderstood. It should probably work.

Good point.

EDIT: a 1-4 CCTV DC splitter uses 24AWG (3.5A/42W) + 26AWG cable (2.2A/26W) so indeed that cable is underspecced for the level of power we require.

It was too simple to be true

Also I've been looking for some sort of AC power adapter with two barrel type outputs like the one included in the vidock 4 package.

Never been able to find one.

Villagetronic users: pls photo the product label on your 150W AC adapter

There's a couple of Villagetronic users that visit this thread. If you are one and have a 150W ViDock4 or 225 ViDock4+ (150W+75W), then can you please take a detailed photo of the top cover of the AC adapter. We'd like to see who makes it so could source it for those users that want the DC jack to be able to power between the two outputs.

It would be easy to then use a 5.5 x 2.1mm CCTV DC Power Male Jack Connector (10-Pack) to create a DC-jack-to-molex adapter for mating back to the floppy molex PE4L/PE4H and/or pci-e power connectors on the video card.

Quick question.

If I was able to obtain a usb 3.0 external expresscard 54 slot would I be able to use that with an eGPU? The speed is as fast as a expresscard 2.0 anyway, so I see no reason why it wouldn't work.

If so, does anyone know a company who makes a usb 3.0 external expresscard 54 slot?


*edit* oops, sorry for this post. I just found nando4's post here about the usb 3.0 interface. Any idea when it will be available?

USB3 to ExpressCard only have USB connection. It missing PCIe connection which is required for eGPU to work. Unless someone rewriting the drivers, it will not work.

Hello,
Well today my pe4h arrived and I am having some issues.

First off if I boot computer, sleep and plug in egpu (power on) and resume I loose all functionality of any USB devices. In GPU-Z it shows as DDR2 and no VRAM
Then after playing around in setup 1x I try to boot and now have no soundcard or wifi card?
So as you can tell I am having some issues. I tried pci-e compaction at 36bit on egpu but did not force it to 32 bit. That showed I had 256mb free. But when I chainload mbr it totally goes spastic and says my internal screen has a resolution lower than 600px and in a high contrast mode. I am not sure what I am doing wrong. I also tried booting with egpu on and it stays on a black screen for ages then also reverts to less than 600px on internal screen in high contrast.

Also trying to boot normally and I still have no wifi or soundcard even though I haven't touched them

Specs:
Dell inspiron 1545
C2D T9400 @2.53ghz
4GB RAM
dgpu ati mobility radeon hd 4330
PE4H 2.4
PSU Corsair CX-430
egpu Gigabyte Radeon HD 4890 1GB DDR5

One other question; Do I have to have the egpu plugged in to my monitor or my laptop plugged into my monitor?

Nando4,
Will you receive a sample of PE4L v2.1 before 20th of February? I hope yes, and we can have a real test from you before we order it.

I don't think the performances will differ from the already released tests (at least if bPlus hasn't found problems on the cable). Anyway would be nice to have further photos of the kit ^^
