So i went and bought this evga 6800gt, installed it and got the 61.72 whql drivers, installed the coolbits thing, etc. So when i went to overclock it, i thought i'd find out how high the "autodetect" optimal frequencies thing would give me...
...so i try it the first time and it says 389mhz core or something lame like that (compared to most ppl's 425mhz+). The second time i try it, i get 401mhz core (second was like 30 seconds after the first try). I say to myself "weird, but lets go for it". I try it and even played farcry for awhile. Then i rebooted, got into windows and had fullscreen graphics fuck ups. it was messed up, i couldnt do a damn thing. So i turned off the computer, unplugged everything, and redid the wiring and plugs until one of the PSU's power cables was only hooked up to the video card, 1 hard drive, and the floppy drive. I boot up, and its 100% perfectly fine, no graphics errors or anything. Video card is at stock speeds.
NOW, after stability has been re-established, sometimes when i "detect optimal frequencies" it will go up to 400ish (never any higher than 402 , how lame
), and sometimes runs for 2 seconds and the screen flashes and it goes back to stock speeds. Is the autodetection thing buggy or is it my card? I kind of want to return it for another one to see if it will have a better OC, cuz this one is very disappointing so far.
cliffs:
1. got an evga, OCed a bit (400mhz), got major gfx corruption
2. redid wiring, was stable, back at stock speeds
3. tried "detect optimal frequencies" at diff times of day, results vary randomly from stock to ~400mhz core (1.09ghz memory).
4. I don't understand.
