okay. I set my cpu to 3.62 ghz and was ready to do some hard core benching.

*I had the rivatuner perfomance monitor running in back ground*

First I set the 6800 ultra too 473/1240 and during the first test right near the end the test froze for 1 second maybe 2 , then it resumed. I immidietly cancelled the test and went to see what the rivatuner thing said. The temperature couldnt of been better but the odd thing was where the clock frequencies were, there was a little dip in both the core frequency and the memory frequency. What could of caused this?

Then i decided to lower down too 470 and when i benched this time the first test completed fine but the half way through the second test the same thing happened again.

Could it have something to do with the droop on my cpu? Im going to up the vcore a little bit more anyway but also could the chipset/agp voltage need upping a little bit because I want the very best.

At first I thought it could be throttling but there is no reason for it too throttle temps are fine and so is power.

Any Idea's anyone?

What temps is it running at? Maybe a power issue.

it's a power issue

Man your nuts. I have the EVGA 6800 Ultra and it acts kinda goofy around 470/1.21 and above. You have a nice card.

It could be power, or your card has just reached it's limit. That is a pretty high overclock man.

470ish is pretty much the ceiling for 6800U on air. Plain and simple. Mine maxed out at 467 with "normal air". The lockup is from heat, I'm dealing with it right now benching with 1.5v on water. Everything is right where it should be for your setup.

Actually, those symptoms look like thermal throttling. Back down the OC a bit, to like 450, then try and see if the stutter happens
