In the comparison, DFI 748-AL, ASRock K7S8X-E and SiS 748 Reference board is running 1 x 512M Corsair XMS3500C2 Stick at CAS 2, 5-2-2. The Gigabyte 7VT600-1394 runs CAS 2, 6-2-2. EPoX 8RDA3+ is running 2 x 256M Corsair TWINX512-2700LLPT at CAS 2, 5-2-2. Looking at the benchmarks, it can be seen that Dual Channel DDR400 does have a better memory bandwidth over the single channel DDR 400.

There is no doubt the nForce2 are getting better scores in this category. If you look further down, you would have noticed that the single channel DDR400 boards aren't that far off. It is also important to bear in mind that, a higher score in memory bandwidth doesn't really affect processing speed except those applications that needs lots of memory bandwidth.

DFI 748-AL scores 2874/2693 which is considered  pretty good. The SiS 748 Ref board runs at a higher FSB speed of 201.9 by default, thus it is higher. Although we have shown on our mainpage that the scores can be higher than what we obtained, we decided to use the latest BIOS for the tests. There is still room for memory performance closing up to 2900+, but that makes the system unstable after a few rounds of tests. The register is thus turned off in this latest engineering bios for max stability and performance.
