Problems with Galaxy Geforce 7900GS on AGP

hydralisk · 08-10-2007, 03:56 PM

Hi. I habe bought this graphic card two weeks ago. It ran smoothly for a week an then started to freeze ingame or desktop.When I run Oblivion itfreezes in the launcher menu. If I enter the game directly it runs a few minutes then freezes. In other not so demanding games I can play longer but it still freezes. I installed latest drivers for video card,reinstalled OS,updated BIOS,installed VIAGart driver and even changed my PSU with a Spire rockeeter 420W but the problem persist. Do I need to connect a certain molex on the card? I think it doesnt recieve enogh power because if I underclock it I can play longer but still freezes. It ran perfectly for a week and suddenly started to cause this problem.
My specs are :

AMD Athlon XP 2500+
1,5 Gb ddr 400
HDD Maxtor 80 Gb
Mobo A7V600-X
And a combo cd-rom/rw DVD-ROM

Spire rockeeter 420W = Poor PSU

I would look into something with a better brand such as OCZ, Antec, Forton (FSP).

check the tempreture of the CPU. Also, if there is a Space to plug in a molex connector, Do so.

See the top right of this picture, Thats where the Molex Plugs in ( If needed )

I have plugged in the molex because the video card doesnt start if I dont.
Im still wondering why the vid card ran about a week powered by a noname PSU ( powerlink). Is possible that PSU got exhausted?

Yes, you can "exhaust" a PSU.
And, yes, I agree with HawMan. You need a better PSU with at least 20 Amps on the 12V rail(s).

Well, it seems that not the PSU is the problem. I tested the card on other computer with a 300W noname PSU and there were no problems. I think my AGP bus got unstable because when I lowered it from 8X to 2X the sistem was stable for about 3 hours.

The other System may require less power as a whole than your computer.

Have you got another AGP 8x card you can try in it?

hydralisk · 08-18-2007, 01:08 PM

Yes I have an ATI Radeon 9250 and it has no problems with AGP.
The PSu has dual 12V rails with max 15 amps on each. Shouldnt be enough?

**Deleted090308** · 08-18-2007, 01:45 PM

Try different molex plugs.

I have found this in everest: "Video BIOS Date 04/09/24" . Is it normal? This date is a bit weird to me? Could this be the problem?

I have EXACTLY the same problems. My PSU is a FSP (Fortron) 400W with 2 independent 12v@18A rails. So the PSU can't be the problem.

I think it's the AGP interface as on another computer works fine. I had the same problems with another card (Radon 9600) on a different computer, just that for that card I could find a AGP setting that would work. For this I can't.

The card worked fine (even OC'd to 633/1800) for a week or so. Then started freezing in games. I can still play some games (W 40k:DOW, 2d games..etc) but on intensive GPU games it freezes within 2 mins. IF I downclock the GPU to 350-400 I can play for 2hrs or so then freezes.

WHAT SHOULD I DO? IF I TRY TO FLASH THE VGA BIOS WITH ANOTHER DO I LOOSE THE WARRANTY?

The heatsink on the PCI-AGP bridge on the card is VERY LOOSE/ has crappy contact with the chip. temps aren't that hich though. Could this chip be borked?
