[SOLVED] ASUS HD 4850 Artifacts

deagle25 · 08-03-2008, 08:42 AM

*****************

PC specs:

Win XP SP2

ASUS EAH 4850

Corsair 750W PSU

Intel Core2 Duo 6400

2 gig Corsair DDR II RAM

Asrock 775 Dual VSTA Motherboard

*****************

ATI Catalyst 8.7 (standard settings)

Crysis patched to 1.2

I'm having very bad artifacts - pointed shapes like big (half the screen) black triangles or stribes like on this image

I just tried MOH Airborne and it shows exactly the same graphical errors

I have ordered a new VGA Cooler and fan.
Installed a new cooler today and the Idle temp dropped from 55 to 43 and gaming temp dropped from 75-85 to about 58 celcius. But that did not solve the problem in Crysis.

I'm thinking maybe it could be my Asrock MB that maybe have PCI Express 1.0 and it should be 1.0a or 2.0? But I can't find the version info in the manual.

Does anybody have an idea where to go from here?

ati are backwards compatible only nvidia have the problem with pcie2
reinstall your drivers
in the device manager uninstall the video card
reboot tapping f8 and choose vga mode
when windows finishes rebooting
disable a/virus
install your drivers
reboot the computer

try the card on another computer to check if it is the actual card

I'm almost 100% sure it's the motherboard being incompatible with the video card. Here is a list of what your motherboard supports:

Not sure why an incompatible motherboard would actually let the video card work normally for anything else other than gaming, but that's my guess. I have an Asrock 775Dual-880Pro and my 4850 artifacts during 3D gaming (Crysis, Company of Heroes, etc.). At first I thought it was the PSU (used to have a 400W, then upgraded to RAIDMAX 530, now a Corsair 520W) but that didn't fix the problem. My temp is also like yours in the 50C range on idle and high 60s during load.

From very intensive googling around for the last 2 weeks, no one else seems to be getting this problem with the 4850 but the Asrock mobo users. If you run into a solution, please let me know!

You where right, hm629. It was the motherboard. I installed a Gigabyte P45-DS3 and the problem vanished

Thank you!
