It is benchmarking slower than the PCI/I-P55TP4XE, but I suspect that is because the book says it will run the 100Mhz chip with 70nS memory, which means they stuffed a wait state in it. I need to get the Sis data books so I can tweak the BIOS values and know exactly what it is actually doing as there are about 12 memory timing parameters. I have not seen source on 128MB simms, and 64MB simms are still hard to find. Oh, and that board supports up to 200MHz chips per the 1.2 Errata sheet stuck in my manual, though ASUS is not stuffing the VRM socket in the board which means you can only go to 150Mhz (All chips faster than 150Mhz use a 2.9V VRM power source). -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation Company Reliable computers for FreeBSD
