I don't understand why my mems clocks so bad, 650 gives alot of artis in windows, and 700 is messed up =) I suspect that I may have 1,6ns chips or that the timings are too tight. I am using ATI-Tool.
Dunno if it will be any help, but I also got the HIS, but with the 1.4ns mems tho, and I had the same problem with the artis at the rams. But when i increased the volts they basicly disappeared, atleast up to 680mhz, but I didn't go any higher cous I was using the stock cooler.
Don't remember exactly what the volts was, but try to just pump them up abit at the time and see what happens, maybe it works, maybe not

I'll fit a copper cpu cooler at my card this week, so hopefully i'll do better than my previous scores/clocks.
