i have 128mb of pc2100 on a soltek 75drv2 with xp 1600, bus speed is 133mhz, cas latency 2. running the sisoft sandra memory benchmarks i cant match the figures of between 800 and 900 that tom's reviews benchmarks have. i get a maximium of 710/710 for integer mmx/floating point sse. the cpu and multimedia benchmarks are upto par though. what is the problem with my memory configuration? the soltek should give a performance similar to the epox with kt266a used for the reviews.
