I'm building my own computer and have a question concerning the system bus. I've been told that the core 2 duos (like the E6850 I'm getting) are "quadpumped", and to find the actual fsb you have to divide the advertised 1333 by 4 to get 333. I have also been informed that to get the actual bus on DDR ram you have to divide by 2, so in this case to get a 1:1 ratio between ram and cpu I should be buying 667 memory. What I'm still unsure about is whether or not 4GB of cheap 667 ram with good timings (something like 3-3-3) and a 1:1 ratio with the fsb would be better than pricier, "higher quality" ram that seems to be more popular with the community (like some 2GB 4-4-4 or 5-5-5 800/1060 modules)
If the cpu is what's bottlenecking the speeds, I don't see why the cheaper ram should be any worse, but just seems like I'm missing some vital part of the equation here or the other ram wouldn't cost so much more and be so much better rated. If anyone could fill me in on that missing piece of information, or recommend I go through with the cheap ram, I'd appreciate the advice.
(also, sorry if this belonged in the memory portion of the forums, I wasn't sure which one to put it in)
*edit - looks like the 4 gigs of cheap 667 memory is no longer there, so replace really cheap 4 gigs with 2 gigs of fairly pricey g.skill ram
still would like to know if this is a wise purchase over the higher bus ram though
