I say get crucial ballistix ram!
My 1gb (didn't have the money for 2gb
) 800mhz cas4 tracer module does 1200mhz cas5. Crucial ballistix ram uses D9GMH ics.
Newegg had an offer on tracer ram a little wihle back...
10th anniversary ram is also good for overclocking..if you can find it anywhere.... :P
