Performance Computing - Q1 2005 (AMD64 and SLI Overclocked)

Overclocking Results

Like last time we will be comparing our system against itself both at stock speeds and maximum overclock. We are able to overclock two aspects of the computer here today. First we can overclock the processor by adjusting the front side bus and secondly we can overclock the graphics cards by adjusting both core and memory speeds.

Using the older AMD Athlon 64 3200+ we were able to achieve a maximum Front Side Bus of 222MHz giving us 2.22GHz, unfortunately this time around we were only able to achieve a maximum of 213MHz which gave us a speed of 2.556GHz. We would have liked to have gotten to around the 2.7GHz mark but due to the processor not being the best of overclocker we were a little limited this time around.

When it comes to overclocking the graphics cards it is no harder then how you would normally overclock your single graphics card. You can load up a program like Riva Tuner and overclock as you normally would. You are only ever going to be able to overclock as high as the worst card can when in SLI mode.

With our default speeds being 400MHz on the core and 1100MHz on the memory we were able to achieve a maximum overclock of 420MHz on the core and 1234MHz on the memory (on both cards).

While we don't have huge overclocks here it will be interesting to see what kind of performance jump we get when comparing the two setups.
