its not water cooled and i OCed my memory because, and I am not trolling you with this one, i just get a bluescreen if I OC gpu but not the memory, don't ask me why.i just figured it out by playing a lot with the after burner. but to be fair, i can only sustain those hashes for about 2 hours, the card gets unstable and crashes then, but when i turn the cpu clock down a little I stell get 770mhash/sec and the card has been stable for about 2 days now.

currently i am at work, but i can upload a screenshot later if you want to. 5970 can potentially hash over 800.
