Noob ram speed question

Dyson · 21 Jun 2007 at 07:29

Right, I understand quite a bit about computers, but the one thing I can't get my head around is ram speed when overclocking.
At the moment I have overclocked my E6600 to 2.9Ghz, with my ram at 800 (unlinked). Is this ok, or should I be overclocking my ram as well?
As I understand it, my cpu is now at about 322Mhz X 9, so my ram only needs to be twice this as DDR ram runs at double this figure. Correct?

Or, does my ram need to match the cpu's fsb?

As I understand it, my DDR2 800 ram will be fine at stock until my cpu overclock passes 400Mhz.

Please, can someone clarify this for me, in laymans terms!

If your RAM is running sync 1:1 with FSB then it should be running DDR2 644, and thus your RAM will allow FSB to run upto 400Mhz without pushing the RAM. But since nvidia chipset allows RAM to run unlinked with FSB it doens't really matter.

So if I leave it unlinked at 800 whilst the cpu is at 325 x 9, im not losing out, right?

No.

It will just run at DDR2 800 no matter what FSB so you're not losing out on anything.

Thanks, thought I was right, just not sure. Ram doesn't need to be touched then unless the cpu goes over a 400 fsb.

Right?

(Sorry if I sound thick, just want to find out

)

If you are running RAM unlinked with FSB @ DDR2 800 then it's gonna stay at that speed regardless of FSB going over 400 or not.

So, performance wise im not losing anything then? By having it unlinked I mean.

No you're not, just means the memory isnt getting overclocked.

Thanks!
