We tested different things on a few HE-SL and LE based boards. In the default setup, we found the LE to be faster than the HE-SL. After tweaking settings on the HE-SL board, things improved and pushed the HE-SL ahead of the LE based machines. We ran a variety of tests, both benchmarks and our own codes. We did our testing remotely with a very cooperative vendor (Atipa-DCG). On the SuperMicro board, there is a "use optimal" setting which improved things over the default. The BIOS allows you to twiddle with the CAS memory paramaters. At this point, we have not determined if CAS 2 versus CAS 3 memory makes any difference on a ServerWorks based board. Has anyone made this determination? I would love to hear feedback. On Thu, Jan 25, 2001 at 09:54:19PM -0500, William R.
