To test the ATI video cards, we used the latest Catalyst 5.7 WHQL-drivers, and latest ForceWare 77.72 WHQL drivers - for NVIDIA cards.
Overclocking
We found issues with overclocking in R430, which we mentioned in the beginning of this material, and we also saw them during overclocking of these three cards. We found out the best overclocking capability for the GeCube RX800XL core (440MHz), whereas other boards showed less impressive results - 425MHz for the Sapphire board and about the same in the PowerColor's solution. This is a serious enough shortcoming for RX800XL as compared to GeForce 6800GT, since the overclocking of the core in the latter is rarely lower than 400MHz - normally it is even higher.
As regards the video memory, Sapphire's and GeCube's boards were able to overclock the memory by 70MHz and 80MHz, respectively. Despite the faster memory, the PowerColor board of 1.6 ns access time showed approximately similar results - 1090MHz. While overclocking like that is acceptable for the former two solutions (the nominal frequency for 2 ns memory is 1000MHz DDR), but we definitely expected much more from the 1.6ns memory (the nominal frequency is 1250MHz DDR).
Finishing the talk about the overclocking capability, we note that not its was not only ourselves who came up against the issue of poor overclocking of boards based on the R430. The same issue was also found by other testers and many users, of course.
