Question about RAM and FSB speeds

post #1 of 8
Thread Starter 
So basically I was wondering, considering the q6600 has a x9 mutiplyer (I think anyway), am I going to have to decrease the multiplyer to run my RAM at anything higher than say 800MHz at a 1:1 ratio?

I plan on taking the Q6600 to 3.6Ghz, so that means the QDR is 1600 MHz correct? 1:1 with DDR2 would make an 800MHz speed?

Sorry if I am confusing anyone. Any help is appreciated, thanks.

yeah

if your ram is at 800 like mine, you can run 8x400 to get 3.2 or 8x450 to get 3.6.

eh. i couldnt get mine stable at 3.2 8x400 so i just ran mine at 3.0 9x333.

personally, i think 1:1 is overrated.

Maybe, I haven't seen any real hard evidence that 1:1 is any better.

Im gonna try a few different combinations depending on how well the CPU does.

Heck, I might even bench different ratios just to see.

Do you have the GO stepping?

Do most people run a faster RAM speed with these CPU's?

I'd imagine underclocking RAM isn't anyones favorite thing to do.

Just keep your ram as low as possible throughout ur overclocking process,
Once ur done overclocking max it out,
Unless i didnt understand your question...

That's because it's not.

On my system (and most other intel systems), all with a tRD of 5 and a 400/1600 FSB: 800MHz 3-3-3-9 < 1000MHz 4-4-4-12 < 1200MHz 5-5-5-15.

There is a point of deminishing returns, however. 1000MHz 4-4-4 is good bit faster than 800 3-3-3, but 1200 5-5-5 is only marginally faster than 1000 4-4-4.

That makes sense.

I need to read up on timings a little though.
