M1687 K8 chipset (3b)
Benchmarking Before we benchmark, we document the FSB the board is running at. The SiS 748 reference board is a bit on the high side. Do bear that in mind when comparing results of the boards as a higher FSB usually will impact the benchmarks in one way or another. ASrock K7S8X-E is registered at 200.97MHz and the EPoX 8RDA3+ is at 200.46 MHz. Gigabyte 7NNXP runs at 200.45MHz and DFI is at 200.47. Gigabyte 7VT600-1394 is at 200.9Mhz, DFI 748-AL is at a very exact 200.45MHz. The M1687 Reference Board runs exactly at 200.00MHz FSB. Sometimes CPU-Z registers 200.01MHz.
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. Our single channel DDR400 K8 ALi Ref board scores a high of 3005/3003. Considering that the memory controller is embedded within the processor, a lot of times, it would depend on the CPU itself. Occasionally, running this benchmark will hang the system even at the lowest ram timings. It can be deduced that it has nothing to do with the DIMM or Chipset but it could be due to the memory controller in the CPU or Sandra software. Update : ALi / ULi sent me an updated BIOS and the problem with hanging in SiSoft Memory Benchmark test is solved. There are no changes to the score.
