Memory?

post #1 of 5
Thread Starter 
alright this is probably a stupid question but lets say you take a qx6800 and oc it to 1333 fsb should you get 1333mhz memory to go with it?

not unless you want to. 1333fsb would be like a 333-334 core speed if my math is right. So if you run a 1:1 (2x) memory divider then you would need 667mhz memory to keep up to a 1333 cpu fsb.

no need. fsb is multiplied by a factor of 4 so divide 1333 by 4 which equals 333. then if you multiply that by 2 you get 667 which is the memory speed you would need to run a 1:1 ratio. 667-800 memory would by fine with that set up. hope that helps

Not really.

DDR2 667 will be enough.

The CPU has a 266fsb and if you overclock it to 333fsb (quad pumped that's 1333fsb), then the 333mhz fsb will only need memory that runs at 333mhz (which double that it's 667mhz), so no need for that.

Then again, DDR2 800, good quality though, it's the best to get as the ratios changes and higher RAM frequencies could be required. Personally I OC the memory at much higher frequencies than the CPU's.
