    • Best answerTo check the specs for compatibility, (if using Windows), Click Start, and in the search box type "dxdiag" and press Enter. On the System tab, take note of the System Manufacturer and System Model fields. Google " [Manufacturer] [Model] Manual" (or replace "Manual" with "Specs") and the specs will be featured in the Memory/RAM section of the manual. Take note of the total RAM allowed and divide by the number of slots on the board, that's the max amount you can have for each slot. (ex. 16GB total divided by 4 slots would be 4GB max per slot) The Manual will also tell you the max speeds and DDR type it can handle.

  • Q: ddr pc2 6400 is this the same as ddr2? thats all that comes up when i look for the DDR pc2 6400  (3 Answers)

    • Best answerAny memory that says either DDR2 or PC2 means the same thing. Likewise DDR3 is the same as PC3. The other numbers indicate the speed of the memory. You should always try to match the speed (i.e. 6400, 10666, 12800, etc) on all sticks you put in the same machine. You can mix sizes (2GB with 1GB or 4GB is ok), but ALWAYS match the speed. Hope that helps.
