Overclocking an EVGA 6800 Ultra PCI-E card to 425mhz

The test button in the Nvidia control panel for overclocking (71.84 drivers w/coolbits) tells me that the card fails at 425. While it is entirely possible that the chip is only good at the stock 400mhz, is that Test feature truly reliable, or can some kind of BIOS override tell it to report back a failure? I wanted to get some opinions before I start running game/benchmark tests.
 
Try OCing in Rivatuner. If you're reallly serious about it, you could also flash your card to a Gainward BIOS and OC with ExperTool, no failure check with that.
 

The test button was a requirement in some older drivers (it would insist on testing before it allowed me to hit OK.) The other button - and I am at work now, was something about hitting "optimize" to choose reclock rates automatically.

I did much higher on my own with no artifacts or stability issue.s
