5ns pc2400 vs 5ns pc2700

Wonko The Sane · Mar 4, 2002

Is there a difference between pc2400 cas2.5 cl2.5 5ns and pc2700 cas2.5 cl2.5 5ns?

What's a more important number to look for, pc2?00 or ns?
thanks in advance.

The only difference between those seems to be the rated speed. The PC-2400 is only good (in theory) to 300mhz (150x2 DDR), whereas the PC-2700 is good to 333mhz (166x2 DDR). You should really look for something that runs cas2 though. much better performance.

but if they both have the same NS rating (both are 5ns) could the pc2400 reach pc2700 speeds? I'm mostly asking out of curiosity the difference in price is only a few dollars.

As far as getting CL2 ram, the ram I was looking at is kingmax, and I've heard that they do well with CL2 at high FSB. I didn't see any kingmax pc2700 CL2 on pricewatch. Is there anyplace else i can look, or are many people running CL2.5 rated ram at CL2?

It's possible. The only way is to try. I hear crucial is good for overclocking and runs at cas2.

Keep bumping this post....I'm sure someone around here has some 2700 at cas2

I'm sure you could try running pc 3000 @ 2700 and 2 cas latency, check out mushkin.com so far the're the only company I've seen that has it.

most of those ratings are underrated. i think those that are rated 2.5 can do 2.

Check out this OCZ ram. Its rated cas2.5 up to 190 or cas 2 up to 183! The best part is the $86 price tag for a stick of 256 MB.

I dunno, but the PC-2400 I have from same mfgr. is outstanding as of yet.

Go for crucial, its only rated for 133 at cas 2.5, but mine is at 174 at cas2 with some ram and northbridge cooling.

yeah my crusial cas2.5 is at 162fsb cas2 with its voltage at 2.8v at 2.9v i am pretty sure i could get 166 stable

so basically if I find ram with a low NS (I think it's a measure of latency, right?) I should be able to hit pretty high FSB with cl2, regardless of what it's officially rated for?
