Naveed Posted November 6, 2006 Share Posted November 6, 2006 Okay here's the situation, I have 2 Gb of XMS2 ram running at 800mhz at CL4 without the EPP feature. I want to go buy another 2 Gb of Ram with the same specs as stated above but with EPP. Will mixing EPP ram and non EPP ram lead to stability issues? This is on DFI infinity NF Ultra II N2 Board. My gut tells me it shouldn't be a problem but I thought it was better to be safe than sorry after putting down a nice chunk of change for the memory.

Wired Posted November 6, 2006 Share Posted November 6, 2006 keep in mind that 4 sticks will generally run slower than 2 sticks due to the load. Why 4 GB though? Link to comment Share on other sites More sharing options...
Yellowbeard Posted November 7, 2006 Share Posted November 7, 2006 It is never recommended to mix different revisions of memory. If you need to add more DIMMs, you will need to add memory of the EXACT same part number AND revision # so that you do not mix different ICs.

Cause I'm running Gaussian 03 a quantum chemical program that uses huge matrices to calculate properties of molecular systems. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted November 7, 2006 Corsair Employees Share Posted November 7, 2006 Also with 4 modules I would suggest the memory frequency be set to 667 Mhz at 2.1 Volts and the Command Rate/CPC needs to be set to 2T as well.
