Am I being stupid here?

1066MHz DDR2 memory will be fine with a 1333MHz FSB CPU won't it?

 

[Jokester]

1066MHz RAM can run off a 533MHz FSB (2132MHz quad pumped for the CPU) when the divider is 1:1 so yeah, plenty of headroom.

 

[Doppleganger]

Absolutely fine yes. All the 1333Mhz bus speed relates to is 333Mhz bus 'quad pumped'. Your 1066MHz DDR2 memory will work easily at 333MHz bus speed, actually being rated to work at 533Mhz bus speed.

yes, it wont be 1:1 with the Q9xxx but it will be ok. You can just ajust your FSB to match... in case you want your PC 1:1 (I do, always)

 

[Crashgate3]

yes, it wont be 1:1 with the Q9xxx

This is just for a living room PC that'll be a general media centre and play the odd low-fi game so I won't be going mad with the CPU. Its just a good deal cheaper for a 2.66Ghz 1333FSB Conroe than it is for a 1066MHz 2.4GHz one, for some reason (I'm guessing its made with a smaller process, so you can fit more on a given sheet of silicon?)

sorry t o hijack but got a similar q.

if i buy a 'Wolfdale' 3.00GHz (1333FSB) what is the best mem spec to buy for a 1:1 ratio

Depends on if you will be overclocking or not.

If not then DDR2-667 will match the fsb.

If looking for around 400fsb (3.6GHz) then you will need DDR2-800

If you are looking to overclock to the max possible then you will need DDR2-1066

Slower ram can be overclocked too but there are no guarantees with that, but take a look around for good overclocking kits and you can save some money.
