New CPU and RAM question

hey! long time since i've posted here.

Anyway I'm thinking about building my own computer (hopefully) and i was looking for a good cpu. I found the Intel Core duo E750 with 2.66 Ghz 4mb cache and 1333 mhz, but i have no idea what kind of ram should i use. :confused
Should i use a ram with the same speed? (PC10666 1333mhz) or a slower one? Also how will overclocking the cpu affect both ram?

Thanks

 

Choose your motherboard, with dual channel for the ram, to get the fsb up,then check what ram will match the motherboard and the cpu, together.

 

There will be others with more information on ram, once you decide the motherboard, as the motherboard manufacturers often have a list of compatable ram, to go with their motherboards- I think, without looking it up, its qt, or, similar list.
Then dual channel gives a multiplier to ram fsb.
Possibilities to look at, but it will depend on the motherboard
CORSAIR XMS3 2x1GB DDR3 PC10666 1333MHz 9-9-9-24 (kit 2ks 1024MB
OCZ PC10666 Gold OCZ3G13332GK 2X1G DDR3 1333MHz Dual Channel Kit
Corsair TWIN3X2048-1333C9DHX: DDR3 240pin 2048MB (2x1024MB) PC10666 1333MHz
As I said- choose motherboard, then keep us posted.

 

Thanks a lot baklogic and i think i would get this motherboard which supports 1333mhz of FSB, but only 800mhz dual channel DDR2 ram. Would this affect the performance?

Thanks

 

Download the manual, and save a copy, on page 31 to 33, the
lists of recommended memory are there.

DDR2 RAM, is the popular current ram, and DDR3 is the new version, and I cannot advise you with that, but someone else might come on and explain more about it.
According to your manual on the motherboard, you can use DDR2 667 ram.
Page 32 (1-19)

 

That was really helpful. Thanks. But I'm still confused as to the gain/loss of performance with using a slower ram speed than the FSB. And how it will overclock tho that's for the overclocking forum..

thanks again. Tony

 

A better explanation is in Kingston's white paper.
Dual channel will give 15% plus extra speed, by its greater bandwidth.

The motherboard manual only shows two compatable manufacturers memory types at 667. Others may well work in it, but .........

To up the fsb , you do need to go to overclocking forum
