another x1950 pro - blem!

[todosmentira]

My new X1950pro likes to throw up these pretty patterns 10 mins into FEAR or during 3D renderer/artefact tester in ATI tray tools:

The problem persists on the desktop, as you can see, when I exit ATI tray tool or FEAR.The weird thing is I went through 3Dmark 05 fine without artefacts. My specs:

C2D 6400 @ 2422Ghz
2 Gb Crucial DDR2 6400 4-4-4-12 @757
ASUS P5B vanilla
Sapphire X1950pro Ultimate (Zalman cooler)
Arctic 7 pro CPU cooler
1x DVD ROM 1X DVD RW
160GB Maxtor
430w Antec NeoHE specs http://www.antec.com/specs/NeoHE430_spe.html

Is it the PSU? If so, can I safely leave in the x1950pro until upgrade if I don't stress the system with high end games,benchmarks etc?
help appreciated.

On my xt if i get graphic glitches they persist regardless of how cool the chip is etc. Only a restart solves it, so may be the same with you pro.

Things to try:
1) Ensure the correct voltage is being applied when in 3D mode for the card (will be something like 1.4volts but you will need to check this out as I have the xt not the pro). I found intially it was only at 2d clocks when running 3d at which point the low voltage of 1.175v to 1.2 v was being applied which wasn't enough for the 3D mode... hence corruption.

2) Set your PCI-E bus frequency MANUALLY to 99mhz or 101mhz (try 101 first), or anywhere upto 110 to see if it solves the problem. My xt was totally unstable and now is rock solid at pci-e 101mhz.

3) Blow a fan over the voltage regulators at the back of the card and see if this helps things out.

4) Uninstall drivers, boot into safe mode, run driver cleaner for ati CCC, WDM, restart machine.. reinstall drivers.

5) A combination of options 2 and 3.

problem solved

Okay thanks for the advice - I'd already fiddled with PCI-E with no luck, so decided to underclock memory instead of upping the voltage and this seems to have done the job!
