DIY eGPU experiences

[User Retired 2]

I suppose then, yes it is working. The welcome screen comes on where you would normally type your password to sign in (I have this disabled for the time being) I tried this about 8-9 different times, and it cuts out every time. Seems to cut right before the desktop would normally load. None of the fans stop spinning and the lights don't turn off, so I can't see it being a power issue. If there are no scripts for what I need, and it's not a power issue, am I just screwed then?

Not sure if screwed, just require some creative troubleshooting for a situation I have not encountered. Not clear what is causing the problem. Suggestion in last post was that the PSU you are using cannot supply the peak power the 9800GTX needs, in which case the video card would just stop working with the PSU still continuing as you describe. So suggest trying a beefier power supply.

Would suggest setting your desktop to go to the onboard video and then manually change it to 'desktop 2' "make this main display".

If you have XP around, could try it too instead just to see if it's something to do with your Win7 load (drivers/startup?).

I just did some quick research. I've got a 480w PSU, which is apparently more than enough to power the 9800gtx, especially since it is the only thing sucking power from it.

I checked all the lights while starting up, and nothing seems to flicker on the card, and the card fan seems to stay in sync with my laptop fan. Just before it crashed prior to the desktop loading, I can hear both fans start to rev up a tiny bit, and then drop back to the normal rate. After that the computer is frozen with no displays, and I'm forced to pull the plug to shut it down and reboot.

Also, ift you have an IM or something, I would be willing to chat on there. I would like to keep this from clogging the thread, and I could post the solution once I/we find one.

Also also, would this problem be solved with the purchase of the ATI 4670?

The other nvidia implementations you can follow from the first post noted general flakiness. Something I haven't experienced with a HD4670. Other thing to try is swap the ends of the mini HDMI lead, or try another lead altogether if have one, just in case there is some defect there.

If buying a ATI card, I'd suggest a HD5830, due later this month. Could be worthwhile borrowing a low end card off a friend (eg:HD4350) to confirm operation on your system before investing more $$.

If you get your post count up, you'll be able to PM.

That seems a little contradictory of the original reason to PM, haha.

Ok, well, I believe my friend has a Radeon something something. I'll see if I can borrow it, and I'll post results. In the meantime, I'll try swapping ends.

Could someone please post a youtube video with this whole setup working? Not a just a feed from the external display showing some game running, but a video showing the whole rig working in real time, from boot-up to game operation with and without card? (Almost like the actual vidock 2 demos)
Perhaps also showing CPU-z, GPU-z, and the windows 7 system window?
It's not that I'm skeptical, its just that I would like to see a proven rig in action before I to devote my resources and laptop to this project.

Ok, so I got my friend's ATI Radeon X1800. I'm running on it right now, so that part works good. I turned on my computer, plugged in the card while powered on, and Win7 detected, installed the drivers, and I was good to go. I suspended the system, and when I resumed it turned up on the external monitor.

Here's the bad news. I tried booting up Lord of the Rings Online, which is my primary want for a better card. The client reinstalled directx, which I took to be a good sign, and then the client booted, the pregame screen loaded, everything looked good... until the openning cinematic normally would have rolled. Computer shut down, and restarted. It restarted back the external monitor. I went to open up a window (forget what) and the screen flickered with horizontal lines, and I got a blue screen of death saying that a device unloaded a pending driver. Computer dumped, restarted, and here I am. Sorry this desc is so long, but figured I'd give what happened in detail for full diagnosis.

Like I said, I'm still running on the desktop card, but haven't tried loading a game yet. Any ideas? I'm stumped.

@shewtemup. PM send.

I was not able to get the PCIScope driver started in Windows 7 64 bit. I could not get a PCIScope snapshot in DOS mode either.

I still tried to compile all the resources used by the GT240 with 2.5GB of RAM

The following PCI config script was used:

setpci -s 00:1c.00 1c.w=2020
setpci -s 00:1c.00 24.l=CFF1C001

publicallyunknown,

I don't have a you tube video, but I can attest that it works. It took a bit of work to get it up and running and a bit of head scratchin, but I'm typing this right now on the external graphics card with no issues, and watching a movie on my other monitor Thanks to Nando for his help! Wouldn't have been able to get it up running without this thread.

My only real advice is to try and re-read this thread and the first thread a couple of times, every time I re-read it I got a little bit better understanding.

Successfully using 4GB RAM on Windows 7 64-bit after running memory reallocation script!!

Using the 9525pr.bat memory reallocation script, I'm able to use 4GB RAM in both x1 mode and x2 mode with my Geforce GT240.

Attached is a device manager memory resources screenshot before the reallocation and after running the 9525pr.bat memory reallocation script.

Also attached are all the scripts used for x1 mode and x2 mode.
