I got this really weird X1900 graphics card.

It has an artifact problem. On the XP load screen and in BIOS, artifacts all over the place. So automatically I assumed the memory is dead on it.


**But** In Windows, it runs fine? Before or after the driver installation, it just doenst artifact. As soon as 3D is launched (ati tool 3d stuff) it crashes, but no artifacts doing anything. Loaded CMD and the artifacts appear only on the cmd screen. Strange.

What I have tried:

Lowering clocks and upping volts (both bios flashes).


The card does not overheat, and there is ample power. The card has been tried in the system its in (P5b dlx wifi, p4 3.2ghz, 2gb ram, cm extreme 460) as well as my system <---.


Any ideas? I am using the card in my bench rig / test bed, so with it working in Windows its perfectly fine as it is, but would like to fix it :) (even if it means disabling pipes and stuff, as I said, its not going to be used for gaming).
 
Very strange....have you tried another card in that slot to see if the slot was bad...
 
my first guess is also the slot, my second guess would be low fan revs when it starts or even the fan is not starting during boot up.....:confused:
 
The GPU is cold during boot and has to first warm the whole heatsink before it could overheat. Sounds like a issues with the GPU/memory itself.

Yep, as stated tried in both my computer and the test bed. My comp runs fine with the 4850 it has in it for hours.

Yeah id say so too, but how to fix it. Clocks have been lowered all the way down to 400/400 (from stock 500/600) and voltage increased from 1.125 to 1.3.
 
if you have artifact in bios it's probably dead,mine do it after a huge overclocked on the memory.rma
