Warghost Posted October 20, 2010 Share Posted October 20, 2010 Okay, I just purchased a new PC, and ordered three sticks of Corsair -Dominator RAM. The RAM sticks were all the same, CMD4GX3M2A1600C9, a matched set. One of the sticks was bad, so I had the company send me a replacement stick. The RAM stick they sent me as a replacement was TW3X4G1600C9D. The timings printed on the label are the same as on the other sticks (9-9-9-24), and the speed printed on the label is 1600mhz like the others. So, I installed it, ran MemTest for an hour or so, and no problems. However, when I run CPU-Z, I am getting some weird numbers back from the SPD tab. The two original sticks of RAM are running at 667mhz, the new stick is running at 533mhz. Other differences are the tRAS and tRC timings. So, here are my questions.... 1) Is the new stick of RAM actually running at only 533mhz? 2) Is my RAM no longer running optimally since it's no longer "paired"? 3) How much RAM do I actually have? The label on each stick says "4GB(2X2GB) 2048MB". Uhh....2048MB is not 4GB. Am I missing something?? 4) Should I return the newer stick and buy another stick of CMD4GX3M2A1600C9 from Newegg to keep them all matched and paired? Thanks for ANY information you guys can provide. I never knew RAM could be so confusing. Arrrgh! Link to comment Share on other sites More sharing options...
