Here you go... I did 1800, 2000, 2200, 2400 (2600 would not boot, though I have had it there before, not sure why at the moment). I ran 3DM06 and Everest memory benchmark and captured the screens. Again, I posted a link to the entire configuration of this system earlier in the thread... if you want me to re-link, let me know. This is done using a M3A32-MVP Deluxe board with DDR2-800 C4 RAM, a 4870 X2 with catalyst 8.8 drivers. 3DM06 was set to default, meaning 1280x1024.

Here are the screen shots.


As one expects, the mem BW, L3 BW and latency track linearly with NB speed. 3DM06 score also tracks somewhat linearly, starting at 13232 for 1800 MHz NB and ending at 13553 for 2400 MHz NB speed.

What is interesting is the CPU score, it peaks at 2200 then starts down.... but I caution you on this... I need to repeat the run many many times to ensure that it is statistically valid... I have not done that.

I may spend some time collecting that information and write an article about the data...
