Should you match memory speed to CPU clock speed?

I am running an i7-920 core with OCZ Obsidian 1600Mhz RAM. Is there a benefit or drawback to having memory that is faster than the CPU clock?

there is no benefit or drawbakc if the RAM is close to the CPU FSB speeds

but if you match them it can be helpful, not always a lot of speed gain but u never know, sometimes u see a big difference

The only draw back would be if your RAM is less stable at higher clock speeds. Because there is little difference between DDR3 memory at different speeds a slower setting that leads to more stability would be better.

My mother board is an AS Rock X58 Extreme, do you think I will have a problem with the 1333Mhz bus on the i7 and the 1600Mhz RAM speed?

just OC the FSB to 1600 mhz or 1800 mhz don't bring the RAM down

The i7 doesn't have a front side bus speed, so there isn't any real speed to match.

I thought only the Lynnfield i7's didn't have an FSB

the 9xx series have an fsb speed, its just called qpi :pfff:

^+1 yeah the QPI

and if the i7 doesn't have an FSB, then what else is there other than a QPI

Yeah. technically both AMD and Intel dont use fsb anymore (since Hypertransport and QPI are actually new tech), but saying there is no fsb is nit picking. Thats like looking at a hot dog and saying "no, thats a sausage and if you call it by anythin else i wont acknowledge you"
