It's from an XP2400+ (running at 2.00 GHz), using a cheapo Soltek Mobo and PC2100 DDR memory (running at CAS 2.5). I'm not sure the other bios settings are optimized either, no overclocking. Unfortunately I didn't have smp version of v.19.03 so I had to use the older v.18.15. Using that one on the 2 GHz I benched 994951, on a Dual Asus board XP1800+ (1533 MHz chips) this version with mt=2 scored 1286896. So if you extrapolate the speed difference from v.18.15 to v. 19.03 and scale linearly the dual factor, it looks like 2 x 2100 MHz should give you the same performance. Those would be MP2400+ chips I guess, but they come at 2600+ now and memory at PC3300, CAS 2.0 no doubt. Time to try out the competition perhaps? :) -S.
