jfine Posted December 20, 2004 Share Posted December 20, 2004 Hello, I purchased Corsair CMX512-2700C2 (PC2700, 512MB) for my PC and it has always worked great. My system is a Dell Dimension 4550 which is a P4 2.4G. It has an Intel chipset (no flames, please :roll:) and supports PC2700. I recently purchased Corsair CMX512-2700C2PT (PC2700, 512MB) which has the same specs as my old one, except it has a silver heat spreader instead of the standard one. When I put in the new memory and booted Windows XP, Norton would disable itself due to internal problems and I would consistently get BSODs after several minutes of system use. I took out the new memory so only the old one remained, and everything worked fine. So then I took out the old memory and put only the new one in the same bank, and the crashes began again. So I surmised the new memory was bad, and got it replaced from the retail store where I purchased it. I thought everything would be fine, because I had never had memory problems in the past, but when I inserted this new-new memory -- I once again had crashes. I was a little more savvy about memory at this point, so I ran MemTest86, and it reported errors on the new-new chip that I had inserted; my original, old memory was fine. I tried every possible combination of old/new memory in all the memory banks, and it was consistently just the new memory which MemTest86 reported errors on. So...my question is: Did I just have extremely bad luck and get two defective memory chips? Or do I have a compatbility issue trying to use 2 sticks with the exact same specs? A friend of mine mentioned he had problems trying to use two memory sticks with the same specs because of dual channeling. As far as I know, my Dell Dimension 4550 does not support dual channeling. Thanks for any advice. Link to comment Share on other sites More sharing options...
