XFX HD5770 1GB Single Slot in CrossfireX Review

Being single slot cooled cards we need to be careful when increasing the clock speeds, we are already seeing 81c with Furmark, so we will proceed with a little caution.

The maximum clocks we reached were 890 mhz on the core and 1240mhz on the memory, an increase of 40mhz on each. This didn't help performance much, a single frame increase in Crysis Warhead for example.

When overclocking, the core temperatures rose by around 3-4c hitting 85c when running Furmark after 30 minutes. We don't think this overclock is worth the minor performance increase at the expense of higher temperatures.
