Same story here. A lot of trouble trying to have my XFX 7800GS extreme edition to do what I expectd it to do. Could not runBF2, Aquamark3, 3dmark06 or whatever before downgrading it to
390@1200 MHz.
Upgraded from an ATI 9800XT and did everything in the right order. Removed my hardware in the " official" winXP way and even ran driver cleaner before I installed the drivers for my new card.
I was in conatct with XFX support and upgraded my PSU, fromatted my drive and installed everyting from scratch. Removed additional (audigy card e.g.) PCI cards.
Nothing!
When I was able to run e,g, the 3dmark06 benchie by underclocking my drivers I noticed that in the overview it didnot list my clock and memory speeds of my card.
When I installed the NGO optimized river based on 84.26 all troubles are gone!
The best score downgrading my card was 2910 and now 3225 overclocking even to
468@1350!!!!! Now it also shows my clcock and memory speeds on the project details page.
Can play BF2 for a whole day now with settings I always dreamed of (1600x1200 with half of the options high and 4x AA, high texture filtering).
I thought the secret was the latency tool but when I started it, it gave the timings that where advised (64 ms), so I didnot change anaything.
I always thought it had something to do with timings, but now I am not so sure.
What is your secret??? Not really important actually but you bet you saved my day!
In your favor for ever!
