Asus A8N32-SLI Deluxe: NVIDIA Dual x16 for the Athlon 64

Memory Stress Testing
The Asus easily handled 2-2-2-7-1T timings at stock speed, as do almost any of the current boards for AMD Socket 939 from NVIDIA, SiS, VIA, and ULi. The board was completely stable at "Auto" voltage or the lowest "2.6V" memory voltage setting.
*7T was determined by MemTest86 benchmarks to deliver the widest bandwidth with the NVIDIA nForce4 chipset. While the board would operate at tRAS of 5T or lower, all benchmarks were run at 7T for best performance.
Tests with all four DIMM slots populated on the A8N32-SLI required a 2T Command Rate with 4 DIMMs in two dual channels. The 2-2-2-7 timings were still completely stable at minimum voltage. This is the pattern seen on every other top-performing Socket 939 board, except the recently tested ATI RDX200. The DFI ATI can actually defy the laws of AMD and run 4 DS DIMMs at a 1T Command Rate to about DDR405. The performance of the Asus is completely competitive with other top-line NVIDIA chipset motherboards for Socket 939.

yes this is a very nice board with the cooler 8 phase design, and heatpipe, no more annoying tiny chipset fan. However, i think this board will be over $200USD =(anandtechrocks - Friday, November 4, 2005 - link
Yea, this looks like a very nice board. Now I'm looking at the new DFI NF4 Expert, those sweet Saphire ATI boards, and this one! So many choices!!One43637 - Tuesday, December 6, 2005 - link
i'm looking to put a new system together and i am also looking at this board.i'm not famaliar with AMD chipsets, but will this board work with the new AMD X2s?

this sucks, haven't evn put my system togther with my epox sli board, and now a board that gives u a 17% boost, CRAP.Brian23 - Friday, November 4, 2005 - link
Anandtech: You say we should upgrade our drivers to the latest for increased performance. However, I am unable to find the 6.82 platform driver anywhere.
