To test the ATI video cards, we used the latest Catalyst 5.7 WHQL-drivers, and ForceWare 77.77 beta drivers - for NVIDIA cards.
Overclocking
Since the board is based on the R480 chip, we expected a good enough overclocking for the chip. That has been verified through practical experiments - we were able to overclock the GPU from the standard 475 MHz to 560 MHz.
As regards the video memory, at that we were in for a very pleasant surprise - we were able to attain the 1120MHz DDR bar. For the memory of 2 ns access time (nominal - 1000 MHz DDR), such overclocking is successful enough.
The overclocking was done under standard overclocking without using additional blowing on an open test-bed The ambient temperature in the premises proved 25 C.
Note that not only our experiments verified the good overclocking capability of RX800GT. Experiments on overclocking carried out by some of our colleagues showed similar overclocking, for both the GPU and the video memory. Therefore, we can assert that many RX800GT boards on the base of R480 will overclock well, which is nice, especially in view of the failure to unlock the pixel pipelines.
