Duel DDR 400 requirements?

[Visser]

When running duel DDR using 400mhz ram, and 800mhz FSB, is it required that i have CAS latency 2(.0) ram? Or can i still use 2.5? Yesterday i was reading a LOT of stuff, and i seem to remember reading something to the effect that 2.0 was required, yet i cant find it again and someone has told me that its not needed.

CAS 2.0 isn't required for Canterwood/Springdale chipsets (800MHz FSB support). But, it wouldn't hurt to try to run at CAS 2.0 even if you have CAS 2.5 memory.

on a similar note I think I read somewhere that the Corsair c2 memory is ok for dual ddr 800hhz setups but not the LL series any truth to this ???

Yeah, Corsair is recommending the XMS PC3200 CAS2 or XMS PC3500 CAS2 modules for use with the canterwood chipset. The Low-Latency memory (includes twinpack) needs a bit of tweaking before it will work.

can the c2 run at the more aggressive timings i.e. 2-2-2-5 (or is it 6?) with the canterwood ?

I don't know if such timings would be stable on your particular Canterwood setup but I see that corsair recommends memory timings of 2-3-3-6 a lot for the canterwood chipset.
