DIY eGPU experiences

[600X]

Another simple question to which I can't seem to find an Answer:

The PE4L v2.1 supports a bandwidth of up to 500MB/s, so basically PCI Express 2.0 (Sandy-Bridge)

What about the PE4H v2.4?

Dudes,
I paid 25$ for the eGPU setup. So how will it be delivered to me?

Usually someone would email you a link.

What about the PE4H v2.4?

Currently only PCIe 1.0 so 250MB/s each direction

The future PE4H v3.0 will be able to deliver 500MB/s each direction so compliant to PCIe 2.0 x1

I have had the same problem with Diablo III, but in my case I disabled the shadows and the problem was almost gone. I will try the FPS cap to look what happens.

In my case I have a Lenovo T420 + Geforce GTX 550 TI + x1.2 Opt.

Capping the FPS to 60 resolved completely the issue to me ( PE4L 2.1 + GTX 670). The problem is related to the bandwidth: when the framerate grows too much and too many coordinates need to be sent, the framerate istantly drops; considering the amount of "objects" present on the scene is easy to understand why there are constant drops on the framerate. Limiting it can fix the issue completely.

Wow thanks! This is GREAT News, because it means I will have the same performance with a ThinkPad X201 (Arrandale!). Yay!

Background FPS cap to 60 fixed the low frame rates in large environment issue in D3 for me. Haven't had sudden drops to low frame rates since. Everything still on high, AA, shadows on, etc.

Hey guys
I've managed to get the DSDT override sorted (big thanks to Nando) however I'm having some really awkward problems getting drivers installed for my PowerColor HD5770.
I am using Win7 64 and have seen that various other have had problems with drivers.

Basically, in the Device Manager, it will recognises the card "ATI Radeon 5700 Series", but says "drivers are not installed for this device".

I've tried using Catalyst (various versions), and tried just installing the driver by locating the C7 driver file.

I'm getting nowhere. I've used Driver Sweeper and tried Removing Old entries in the Registry and starting again, but still can't get the drivers installed.

I feel so close as it is recognised, but frustrated I can't get it to work at this stage.

Any advice is massively appreciated as always
Cheers guys.
Matt

Have you tried to install drivers via the Device Manager?

Simple, but often overlooked.

[mattbuzz]

Yep tried that, it just says "drivers are not installed for this device"

But thanks. I'll have another try with that to exhaust the option though.

Hi,

I am a lenovo x200 user with following setup:

x200, win7 32bit, 4 GB RAM
gtx 560 ti
430CX power supply
PE4H 2.4

I am able to setup the x1 link, but the performance in Diablo 3 is really bad so I have to consider Optimus.

I followed this page to install the verde driver, but then I get error code 43. (I use F8 key to halt the startup of Win7 and at that time plug the egpu)

Tried several ways without luck:
- only use 2 GB ram
- Use F8 to halt the win7 and select enable unsigned driver.

The verde driver works on x1 link (without optimus), so I think it is not the problem of the HDMI cable or the driver. I check the problem code in the detail tab of the video card device, the code is 0000002B.

Have anyone experienced similar problems? Really appreciate your help. Thanks.

UPDATE:
I tried to put machine to sleep and then connect the egpu, this time no error 43, the driver works properly, however, the optimus is not enable. Any ideas? Thanks.

BR,
nevup

Setup 1.x is not a program to check the possibility of using eGPU. It`s made to overcome problems that rise during the connecting and setup of the eGPU.
But the idea with the check is interesting

Thank you. I've made some research and I helped myself in Windows. Unfortunately I found that 8540p has motherboard resources, which you say are unmovable unless someone reprogrammes BIOS, in the middle of the PCI bus address space (D7600000-D7600FFF). Too bad

BTW dGPU mem space is unmovable as well? If so, I don't see any space where to fit 128+64+32MB because the only free space is D7601000-DFFFFFFF (137MB).
The dGPU takes C0000000-D1FFFFFF.

All the motherboard resources memory ranges according to the Windows reportings are as follows:

fed1c000-fed1ffff
fed10000-fed13fff
fed1b000-fed1bfff
fed19000-fed19fff
d7600000-d7600fff
e0000000-efffffff
fed20000-fed3ffff
fed90000-fed93fff
fed45000-fed8ffff
fec00000-fec00fff

Do you think there's still a chance to get Fermi cards working?
