It's not just massman just the rules, you could submit to contest but not for HWbot points......but for contest only highest score counts.
That chip was looking promising till we found out the IMC was weak, and also killable with high vdimm :(
I almost killed my chip trying to match your chip for core clocks and still shy of 100 mhz :(
Your ram being higher on your 5850 means little in vantage, when we pretested the 5870 was worth over 500 points more stock versus your 5850 card clocked ;)
Plus i'm willing to kill my card ;) would hurt far less than if we killed yours.
