FSB:Memory divider question

[symbul]

Hi,

If I set (overclock really) the FSB of a P35 board (any brand) to 400MHz and I have DDR2 PC2-9600 (1200 MHz) memory, what would I need to set the FSB😀RAM divider to? I'm thinking 1.5, but I'm assuming that PC2-6400 (800MHz) would have the divider set to 1:1

Anybody tried 1200 MHz memory yet and is it worth it?

Ciao!

No, and IMO, no it's not worth it. High speed RAM doesn't really give you hardly any real world performance improvement.

If you want real world, you use a socket 478 Celeron with DDR1

To the OP:

You would need to set your divider to 2:3. What kit are you looking at? A lot of the nice 6400 kits can do 1200MHz @ 5-5-5-15, so unless your 9600 kit does 1200MHz @ 4-4-4-12, or it can reach that using low voltage, its not really worth it. If you're looking for a 9600 kit, I have a Kingston KHX 9600 2x1GB kit brand new I'm parting with. PM me if you're interested.

Thanks for the info. I have an old nForce4 system that I'm about to totally upgrade to the new stuff (P35 motherboard, 4Gb memory, etc.) but I want to wait a bit and see if Intel will produce an E8600. With its 10x multiplier, you would get a 4GHz system just by OC the FSB to 400MHz. That's sweet.

You will be waiting a long time.

Well, several web sites mention it will be released either in June or Q3 in order to be competitive against the AMD Tri-core Phenom.

running ram faster than the FSB is pointless

Easy: Bus speed X multiplier

So if you are using a 400 MHz FSB at 1:1 thats DDR2800. 1.5 gives you 400 X1.5 or 600 I.E DDR2 1200.

Is it worth it? the consensus seems to be no.
