Problems overclocking 6800 GT

Ok Ive read many reviews of the card etc with the one I bought the eVGA Nvidia 6800 GT, Everyone says its been overclocking easily with air cooling to 400ish, Done via coolbits2 and rivatuner. So the card can be overclocked even a slight overclock shouldnt be a problem, heres where my problem / experiences come into play...

Whenever I install coolbits / rivatuner and up the core by 5mhz, Putting me at 355 above the stock 350, 3dmark crashes when I run a test, and when the computer restarts often times when windows loads I wont have any icons on my desktop. Ive tried this with a bunch of diffrent drivers and It seems im not having any luck at all. Every overclocking guide / literature im finding all pretty much state the same thing, go up slowly in increments, until you see artifacts / snow, my problem is the system is becoming unstable with any hint of overclock. Am I overlooking something??

With stock speeds the card completes 3dmark 03 and 3dmark 05 tests with no problem, no problems running doom 3, Starwars battlefronts etc, Done a few torture tests on other programs with no problems. The card is staying pretty cool, it seems to have no problems running under full load. Any help or advice is appreciated...

Misc Information: 7 Case fans, Pci slot below the agp slot is empty, Windows Xp Pro Service pack 2, AGP Arperature Size 64.

Ok for some reason i cant increase my 350 core speed to 355 without my computer crashing. But Ive successfully increased it to 4.08 / 1.11 with no problem. Kinda ridiculous but I guess I cant complain. 3d Mark went up from 4,600 to 5325.

Well it's only my guess that it could be your cooler. Can you check the temps? See if it's getting too hot. You could possibly invest in better cooling for the card, or try to re-seat the current cooler. BTW if your games and everything run fine right now, then why even bother overclocking? Why not wait till games start to suffer before trying to O/C

Coolings fine, 7 case fans. The cards overclocking fine, for some reason it just wasnt completing the test with 355-370, but higher than that isnt a problem. Im running a core of 4.19 and running the memory at 1.17 and the cards ideling at 48c, after running torture tests and 3dmark05, clicking on the temp window as fast as i can when its over, its showing the card at 55c or less, so im assuming its getting cooled off very fast.

Yeah its 05 lol, if it was 03 you could double my score and add 2,800.

Ah I forgot about this post, the problem ending up being a bad stick of ram. After trying every other possiblity and adding to my cooling system even though I knew it was fine, memtest86 revealed all. Popped out the bad ram on a rma and everythings nice again =D
