Hey all, i pretty recently picked up a geforce 6800 to breathe some life into my aging maching.
I hastily installed it after uninstalling my old catalyst drivers, downloaded and installed the latest forcewares and loaded it up. Seems like i was given a dodgy card because the VGA-output displayed quite distortedly, with flickering and white streaks coming out of any black pixels, but the card came bundled with a DVI-to-VGA converter, which works fine (i use a single monitor anyway). However, recently ive noticed quite an alarming issue.
Having unlocked the 4 pipes and vertex shader (inducing minor artifacts, due to damaged pipes, but definitely bareable (some textures flicker greenly, only if you look close and hard though)) and overclocking from 325/700 to 423/901 (max artifact-free core/mem config), things were pretty good- managed to squeeze 4983 3dmarks from the system. However, i noticed that my CPU scores were lacking after the pipe unlock, so decided to redo the 3dmark run. I was greeted after a shower by 2500 3dmarks. Now, i have no idea why this happens, and it seems to reset after every reboot, but it seems like my graphics card "throttles down". This isn't a temperature issue, as according to "asus smartdoctor" my cards core never tops 62 degrees Celsius even under ATI tool "scan for artifacts" load, nor does the memory top 55 degrees (this is with a VF700 i installed), which i understand are quite safe temperatures. Also, my clocks aren't unchanged, and neither are pipes disabled- i still notice the minor artifacts inherent with the unlocked quad, and the clocks are still set as they should be.
A possibly relevant issue is that i can hear something like a crackling, tittering sound coming from the graphics card when i stick my ear up next to it- i hope this isn't indicative of some faulty component supplying my card unclean voltages or what not. It would be a reaall pain to have to replace or give it in for checkup, as it would mean having to pry off the zalman heatsinks, reinstall the stock cooler, etc....
Anyway, does anyone know anything related to this issue, or can anyone give me any idea of what could be wrong? I'm gonna try a reformat soon (need to anyway) to see if that may somehow magically remedy this problem- its very strange, and honestly i was a bit scared after only getting 2500 3dmarks, as to perhaps i may have damaged the card.
Thanks in advance.
