Memory question on the Intel side

corsair 1066 memory

corsair 800 memory

I'm not up to speed on Intel requirements, still use a dual core Opteron. My friend just upgraded, and had a good question. Are timings as important as they were for AMD? Why is the second set of ram so much more money than the first, is it just the timing? At stock speeds, which set would deliver more speed thru the memory? Which would be better for a good overclock?

Mind you I know you can find cheaper ram, thats not the question. He likes Corsair, its down to one of these two, just dont know which is faster per se.

The PC6400 is Micron D9GMH (or GMK) modules, and will run at lower timings, or at higher speeds (frequencies) than the PC8500. I'm almost certain that that PC8500 uses some of the newer ProMos IC's, which don't clock as high.

so the timings on the second one will allow more speed, or the higher mhz of the first one?

anyone? is tighter timings just as or more important the mhz for the ram?
