*Samsung TCCD from OCZ and other Memory manufacturers is currently binned into several speed grades. Our test memory would be equivalent to current OCZ PC4800.

Tests used OCZ PC3200 Platinum Rev. 2 (current equivalent OCZ PC4800) which uses Samsung TCCD chips. All memory ran at 2-2-2-7 timing in all benchmarks.

We tested the Asus A8N32-SLI using both single and SLI MSI NVIDIA 7800GTX with NVIDIA video driver 81.85. Once we discovered the improved performance, we also ran a full retest of graphics and gaming benchmarks on the DFI LANParty nF4 SLI-DR for comparison. Resolutions in standard benchmarks were 1280x1024x32 unless otherwise noted. Some standard tests like 3DMarks and Aquamark set standard tests automatically to 1024x768 to force a consistent comparison. Gaming benchmarks were run at 1600x1200 with 4x Anti-Aliasing and 8x Anisotropic Filtering enabled wherever possible. SLI game benchmarks were also run with 4xAA and 8xAF where possible.

Results for the Asus A8N32-SLI are in red, while results for the retest of the DFI LANParty nF4 SLI-DR are color-coded orange. Results for the other boards are in blue. Other board tests used the 6800 Ultra for testing unless otherwise noted and are included for reference.

We added Quake 4, F.E.A.R., and Splinter Cell - Chaos Theory to game benchmarks in this review. Asus targets the A8N32-SLI at the gamer, and these recent games should provide a better picture of the Asus performance in the latest games. We will be adding Battlefield 2 and Call of Duty 2 benchmarks in future reviews. The benchmarks that we have been testing for these two games are not completely reliable for both single-video and SLI testing, so they were not usable in a review that compares SLI performance. As we find solutions to these issues, we will benchmark with these new games.
