What is more important? CAS Latency or faster DDR

I was wondering what would provide the best performance boost. PC 3500 (DDR 433) with a CAS 2.5 Rating or PC 3200 (DDR 400) with a cas rating of 2.0? I know that my motherboard at this time only allows a FSB of 333. However, I'm trying to think of the future.

ALSO, I heard that you are suppose to run the ram at the sam speed of your FSB. That would mean running at pretty much PC 2700 speed (DDR 333). IS this true or can you run both the ram and the CPU at different speeds?

Well, I dont' think there are any motherboards out there that support ddr433, so if you bought ddr433 with 2.5 cas latency and ran at ddr400, it'd probably be able to run with 2.0 cas latency because it is made for a higher speed. So really, there wouldn't be any difference at all. Also, running your ram at teh same speed as your fsb does yield faster performance, but only if you have an xp 2600+ or above because they have 333mhz fsb.

DONT touch DDR433 as twin mos 4.3NS is not realse so what you buy is overlcok ram or in others word you pay for a new sticker.Also no OCZ or GEIL or any others no name.

Just tell you that PC 3200 cas 2 from corsair can be overclock at 433 cas 2.5 if not 2.0 as long there only 1 dimm use and a asus mothers boards a Ecs will nerver surve this timing.If you just look perf is still RDRAM the best choice.

Also forget also about AXP bad choice as the cup you buy cost the same price and performe less and cheaper but if you dont like intel for unprove reason go with AMD

juin stop spewing your intel fanboy crap. The ONLY intel p4 CPU that is faster than an AMD is the 3.06ghz p4.

Though you are right on the point that ddr 433 is not worth it and its best to stick to ddr 400.

AXP is better than Intels, at least IMHO, because of the net performance. Look on the reviews. Rarely does the P4 win severely over the AMD, and the XPs overclock nicer, at least from what I've seen. Also, the nForce2 motherboards have better features and are generally better boards than any of the Intel chipsets.

Again, this is only my opinion, but it is shared by more people than you think, and considering THG uses it as their main testbed........

Bah.. Nforce doesn't even have raid... bah... if your buying a comp today I say go for indtel with dual ddr with option of kicking up your fsb for futute cpus...

Nforce is decent but beleive it or not with dual ddr 266 I can smoke a dual ddr 400 equivalent with nvidia... their memory controller is not as efficient...

I don't know if it helps or not..
but I have a PC2700 Samsung Memory
I've try to set the memory to DDR333 at CL2.5/3/3/6, and set to DDR266 but with highest speed at CL2/2/2/5
I compared them by running 3Dmark2001
I got higher performance with DDR266 at 2/2/25
so..personnaly, I think the Speed would be more important
I guess it's also depend on CPU, cuz I have Athlon XP with FSB 266, if you have FSB 333..then I think 333 would be better..but in any case, there is a difference with memory, but not that big

Um... excuse me? NForce doesn't have RAID? While it's true that RAID isn't built into the chipset, most (if not all) manufactures offer nforce boards with on-board RAID. Check out the MSI K7N2G for one.

I'll let you know when I've actually assembled my computer. It's still in 20 boxes on my shelf.
