I have a PNY 2gb pc2-6400-800mhz RAM module. I opened CPU-Z and went to the memory section and it told me my DRAM frequency was at 400mhz. Because it is a 6400-800mhz I thought it would run at 800mhz. DDR ram runs at 400mhz why is my high grade DDR2 running at low speeds? It only says that it can go backwords to 533mhz, 667mhz, and max 800mhz. any help?
Yes, it can be a little confusing. There is a big difference between memory frequency and memory clock. The memory frequency will match the FSB frequency. For DDR2, each bus cycle generates 2 memory clocks.
Everyone seems to use and define these terms a little differently.
Thank you.. I Finally took a day off of work to overclock and I couldn't remember what ram I had. So I looked it up on Newegg and saw 1600 but then I remember I saw 800 in Cpu-z. and then I really was like huh.. Thank again.
