x2900GT minimum frames.

[shaffaaf27]

ok so i had a 7800GT, whos memory was borked, so i bought a x2900GT for £25. i tested out cod4 on all low at lowest res, getting 91fps avg and about 30 minimum for the 7800GT, and the avg for the x2900GT (so by this i know at the lowest res its CPU bound), BUT the minimum went to about 2. i can really feel the stutering while playing cod4 online, and its hurting my play. is there somthing i can do about this?


also when i clock it up, and it goes to 3d mode, it stays for some reason at 503 and 503 not moving up to the 700/1000 i clocked it to.

ill try earlier driver, or first, hotfixes. i am running 8.6

the 2900GT only has ONE 8pin. i am using a 6 pin in that. and using rivatuner to OC not CCC, which wont work w.o an 8pin

well i OCed it fine, but it got worse. then i took ti back to stock clocks and it was better, and took it to 8.4 (after 8.6 and 8.5) and was much better but it still happens every 7-8 mins, the minimum drop from about 30 odd to about 1 - 2.

never used to happen with my 7800GT....

i have a tagan 430W u15. which has 20A on each of its rails, and a combined rail of 26A

i used youruninstaller 2008, and drivercleaner and driver sweaper to get rid of nvidia.

as i said OCing is fine, its the random minimum frames droping to 0 and 1 which annoys me.

it never happened with the 7800GT. luckily this card is only for a week, before i get a 4850. but i hope this doesnt happen witht he 4850.

i heard these problem persisted with 3870X2s, if so how did they fix it?
