Looks like blameless had a bad apple in terms of what the core can do with voltage. Good overclock with the 850 core!

What are the orig speeds for the 5850?

edit: Why is your card at RMA?

Ok, so you hit 1k core and 1.2k memory by increase the core voltage to 1.3 right? Did you increase memory volts? Does smart doctor save your overvolt settings on start up?

Yes, but when it lost, it lost bad. 512mb framebuffer isn't enough to run AA in titles like Crysis at 1920+
