My XFX 5850 is doing about 280 Mh/sec and is actually sitting at 55 degrees celcius. O.o
I overclocked it using MSI Afterburner as far as it would let me move the slider to the right. Weird that y'all are experiencing such higher temperatures.
We overclocked it farther than that.
Indeed. My 5850 is running at 394 MH/s, 1000 core, 180 memory, and 69C.
