Thoughts on Corsair memory

yoongkc · 05-16-2008, 05:30 PM

Anyone has any thoughts on this ram: Corsair PC2 6400 XMS 4GB kit (Cl 4)?

And how's the comparison with this ram: OCZ PC2 8500 Reaper 4GB?

Hope to hear from everyone soon! Thanks!

Between the two, I'd get the Corsair. The OCZ Reaper kit is a little faster and a great set of RAM, but very expensive. If price is no concern, then the Reaper kit is among the best in that price range.

You sure you'll be able to use that 8500 ram? To use it to it's full extent you'd need an FSB of 1066*2 which would be 2132Mhz...

actually he'd need an fsb of just 1066, because true ram speed is half. so since his ram is actually running at 533mhz, his fsb only needs to be 1066 to run it at full speed.

and personally i prefer reaper, but maybe thats just because i have a set of PC6400. but its great stuff for overclockers!

No? DDR2 ram needs to run half of your FSB ?

I seem to remember that very well somehow, and I can't seem to get the feeling I might be wrong here...

you were right about multiplying one of the speeds, but it was not the fsb. you take the actual fsb speed of 1066 and the actual ram speed of 533, and multiply the ram speed by 2. they match up evenly so you get a 1:1 ratio.

i can understand how you got confused though, you were only off by a little.

The Quadpumped FSB needs to be twice as much as the speed of the DDR2 memory ?

We're I to have a 1333mhz (Quadpumped) FSB, I'd need 667Mhz DDR2 to run 1:1 ratio ?

That's what I said right ?

I seem to be unclear when saying this all the time, to say it correct I would have to say:

Your bus speed, in general on a newer Intel, would be 333mhz... And then your FSB would be 1333 because the FSB is always counted in Quadpumped with newer models (most not too much older models tend to have Quadpumped FSB's as well).

And to run your Memory at a 1:1 ratio with the FSB your Memory would need to be half the speed of the (Quadpumped) FSB. So if your Bus speed is 333Mhz then that would been you have a 1333Mhz FSB, and half of that would be 667Mhz.

So for a standard clock Intel of the newer series you would need to have a 667Mhz DDR2 Memory to run 1:1. And with some models you would need 1066/2= 533Mhz DDR2 Memory.

hold on let me get my head on straight.

ok. earlier i was running my e4500 at an fsb of 500 in the bios. that equals 2000mhz, so im thinking both of us were wrong.

you take the fsb before quadpump, double that and you get your memory. not after quadpump like you thought, and its not identical to your fsb like i thought.

EDIT: god i think i misunderstood your first post. you were right after all werent you? when you said 'half of your fsb' i got confused even more.

sorry m8 i had the right thought but i said it completely wrong.

Timo · 05-16-2008, 10:22 PM

Ha! So in your face

Never mind me, I just had to say that. We can all be wrong but I know I was right this time.

Your FSB needs to be twice as much as your Memory speed

(so your FSB --> Quadpumped as always)
