Testbed and Methods

The point of our today’s testing is to check the performance level of the new SiS755 chipset compared to the competitor products. Some time ago, we tested thirteen mainboards on NVIDIA nForce3 150 and VIA K8T800 chipsets (see our Socket754 Platform: 13 Mainboards Roundup for details), so it was an easy one to choose a rival for the SiS755 reference board. The only factor to limit out choice was the fact that the reference board from SiS had slightly overclocked processor bus (by about 1%):

So, we took a Chaintech ZNF3-150 (NVIDIA nForce3 150) and a Gigabyte GA-K8VT800 (VIA K8T800) that also have a slightly overclocked FSB. Moreover, according to our tests, these two mainboards are among the fastest products on the corresponding chipsets. The testbed we used to test SiS755 looked as follows:

• AMD Athlon 64 3200+ CPU (2.0GHz);
• Chaintech ZNF3-150 and Gigabyte GA-K8VT800 mainboards, and SiS755 reference board;
• 512MB DDR400 SDRAM (2-2-2-6 timings);
• NVIDIA GeForce FX 5900 Ultra graphics card (Detonator 52.16 driver);
• Western Digital WD400JB HDD.

We ran the tests in Windows XP Professional SP1 with DirectX 9.0b installed. We also used the following chipset drivers: NVIDIA nForce3 Unified Driver 2.65, VIA Hyperion 4-in-1 Driver v.4.49 and SiS AGP Driver 1.17a.
