Hi Steven. What is your current config? if your CPU is still runing at 140fsb that would explain the slowness.. in general you should keep your memory synchronized with the CPU.. so, if you are running 140fsb your memory (if sync'd, 100%) will also run at 140MHz which is quote slow. You may wany to back down the multiplier to maybe 11-12.5 and up the fsb bus.. if you can get it up to 180+ your memory bandwidth will increase..
Please let us know exactly what you have and how it's configured in BIOS.. have at my sig for that..
try turning down the multiplier to maybe 12.5 - 11 and turn up the FSB.. that would help to increase memory bandwidth since it is in direct proportion to the CPU FSB.. also, this would be better for your CPU.. 1.85v will generate a lot of heat which is fine if you have some serious cooling..
