Chance are big it will run @ 133MHzx2 (pc2100), but on few case it may run a little less for stability issue. There are other posts answering that question on this board, with higher english/technical level than mine Internet <=> Share all we can. jammydodger February 19, 2005 9:30:47 AM All DDR RAM is backwards compatible with lower speeds so it will work in your board. However it will lower its clock speed to 133Mhz (266Mhz DDR).
