Thanks for the info, should add it is a PIII-933Mhz (not o-c'd). I'm mainly concerned about incompatibity (between brands) and how many banks the CUSL2 will accept (I know it has six banks, but also know it won't read all six)? Are there specific banks it prefers (e,g L/R side of DIMM, consecutive banks, non-consecutive)? Probably more technical than I need, but would like info anyway. Thanks for the input.
