Dominique Posted October 21, 2006 Share Posted October 21, 2006 Hi folks My system (a vanilla P4C800 with a P4 3.0 GHz) has been running for 3 years two 512 Mb Corsair 3500xms sticks. I want to add some memories now. Would Corsair TWINX1024-3500LLPRO - TwinX 1 Go (2x512 Mo) or Corsair TWINX2048-3500LLPRO - Twinx 2x1 Go be compatible ? thanks !

Sorry, but they are not compatible with each other. First, the IC chips used to make your current 3500XMS sticks are no longer being produced. Second, the SPD-programmed timings on the new and the old sticks are different from one another, resulting in your motherboard's BIOS being confused as to which timings to pick - your system will either refuse to POST at all, or your BIOS will set molasses-slow, fail-safe timings and speeds. Third, you should not mix different system memory IC chips in the same rig unless you want to risk major problems down the road. However, an older Socket 478 Intel platform such as yours is somewhat more "forgiving" than current AMD and Intel (Socket 775) platforms of mixed modules. Oh, by the way, Corsair is closed on weekends, so you will not hear from the RAM GUY about your question until Monday. Link to comment Share on other sites More sharing options...
Dominique Posted November 4, 2006 Author Share Posted November 4, 2006 thanks :sigh!: If I get the old sticks off the mobo, the new 2 Gb sticks would then work ? In others words what are the sticks compatible with the P4c800 nowadays (not E not deluxe) ? Link to comment Share on other sites More sharing options...
CMC_SAVAGE Posted November 4, 2006 Share Posted November 4, 2006 If I get the old sticks off the mobo, the new 2 Gb sticks would then work ? Yes. You just can't mix them. Link to comment Share on other sites More sharing options...
