OK, as far as I can understand, this is all compatible, right? My problem is that since ever I first installed these two memory cards (which should supposedly max at 667MHz each) I can't seem to go past 333MHz each according to my BIOS, CPU-Z and AMD CPUInfo.
What's going on? Am I missing something here? Why can't I get frequencies higher than this?
I read my MB manual carefully before upgrading the memory and it says it can handle up 667MHz ECC. The CPU is also supported by the MB perfectly, so I guess it can't be that the CPU won't run past 333MHz either. Actually, I can't find that bit of info anywhere, so it's just a guess based on the mutual compatibility with the MB...
The following is an excerpt from an old post I did.
"Using the Q6600 as an example, the FSB frequency is 266 MHz. The matching DDR2 memory clock for that frequency is 533 MHz (266 X 2). DDR2 memory transfers two chunks of data for each bus cycle, hence double the frequency. Each bus cycle generates 2 memory clocks. So, to run 1:1 at an FSB of 266 MHz, we need DDR2-533 RAM.
What CPUZ does is a little confusing. It will tell you that the memory frequency is 266 MHz for a 1:1 ratio. "
In the computer business, there is a big difference between frequency and clock.
