Can Someone Please Verify

post #1 of 11
Thread Starter 
Hi there, can someone please confirm that this is correct:


I'm currently using Presler D930 CPU (Stock 200Mhz CPU FSB)

I overcloked it by 40% therefore i'm running (200Mhz*1.4)=280Mhz

and to have my FSB:RAM ratio 1:1, i'll be running my RAM at the effective clock speed of 560Mhz? so in esscence, i'm UNDERCLOCKING my PC6400 (800Mhz) RAM?

if all of the above is correct, then the requirements of RAM for a Q6600 overclocked by 40% (373 CPU FSB) would only require me to have RAM running at the effective speed of 746Mhz for a 1:1 ratio? and therefore, my current set of RAM (PC6400) would be MORE than sufficent?

is that correct? if so, why would people go for 1066Mhz+ RAMs?

Yes you are correct.

I got 1066 RAM for overhead, and because my motherboard has set ratios I can chose from. So I can have a 1:2 ratio, or a 5:6 ratio, and so on. The higher MHz DIMM's are also faster in benchmarks, because they're made to go faster.

Yes. Your RAM is underclocked.
Yes. Your RAM is ready for a 1:1 40% o/c with a Q6600 (it's even ready for a 50% o/c)
Some people prefer numbers like 525*9.

thanks,

so what u're saying is that 1:1 FSB:RAM ratio is NOT the optimal ratio?

Nah, 1:1 is a great ratio!
However, it get's to the point where faster RAM becomes more of a factor than the ratio.

Yeah. 1:1 is optimal, but my board has other options, I was just saying why I got it. With the speed of things now a days, if you don't have 1:1 it won't matter much.

oic! thats something new, coz i've heard from a few places and articles saying that anything greater than a 1:1 ratio will be negligible in terms of CPU computation.

so i should raise my RAM speed as long as i can keep the same timings? ignoring FSB:RAM ratio altogether?

Well I wouldn't ignore it, but it's not as important as it used to be. So you are pretty much right. Take the RAM as high as it can go, then tighten the timings as much as you can. Some ratios are goofy like 10:13 or something but whatever. It's all fast

Oh yeah, it is all fast!
You will notice tho, that a lot of us like our 400*9 or 400*8.
1:1 just feels good.
