In Need of Guidance

post #1 of 5
Thread Starter 
I'm going to be building a new PC in the near future. However, before I jump into it I have been doing some research. I've looked around the net and have come to the overall conclusion that DDR2 seems to be the best way to go. However, which speed should i settle with? DDR2 800 or DDR2 1066? And if the CPU FSB is lower than the RAM then I won't be getting maximum performace, correct?

So, For Example:

If I were to go with [Intel Core 2 Duo BX80570E8400] with a FSB of 1333Mhz and went with DDR2 1066, to get my system to perform at its max capability, I would have to overclock the RAM to meet the FSB of the CPU?

Any help would be much appreciated.

actually, 1066 ram is much faster than 1333 fsb... remember ram is dual data rate, fsb is quad. fsb 1333 has a base clock of 333, while 1066 ram is 533. 1066 ram is not a waste though, as you can hit very high fsb speeds with current dual cores, so you'll be able to run the ram 1:1 with the fsb, which is the best configuration. you can the cpu at 4ghz with a 8x500 config, and maybe tighten the timings a bit on the ram, whereas 800 ram would be unlikely to oc to 1000.

I'm happy with my DDR2 1000 RAM I've got. I can't run 1:1 with my set up, but I really don't need to anyway. You can get the same set I have here for half the price I paid for them about 6 months ago. Good RAM, but the RAM itself doesn't OC far if you're concerned about that. The settings you see in my sig are about the max I can squeeze out of it.

Ahhh. Much clearer now. So I will be fully utilizing my RAM as long as its MHz/2 is greater than my CPU's FSB/4 ?

And how does the FSB of the mobo come into play?

The FSB of the mobo will be the effective FSB of the CPU. They are one in the same. It's the channel of communication between the two. So if your mobo is rated for 1333 FSB and your CPU is rated for 1066 FSB and you're at 1333, then you are OC'ing your CPU but not your mobo.

And yes you will be utilizing your RAM as long as DDR/2>FSB/4.

For me it's easier to think of them in terms of their base amounts as it makes the math easier, and I need easier math.
