RAM upgrade help

[DWW]

Hello and good evening,

I want to put DDR into my ECS K7S5A Pro and take the PC133 out and put that into another workstation. So I figured that I'd buy a stick of 512 DDR from Crucial. Now since I want to "future proof" the RAM, for less than $10 more than PC2100 DDR (the max K7S5A Pro supports speedwise), I can get PC3200 instead (DDR400).

Only problem is that their DDR400 has a CAS Latency of 3 instead of 2. Will this pose a problem you think in the future? Is it easily stable at CAS L= 2 if I wanted ?

Thanks.

i think the speed rating will make a much bigger difference the the cas latency will. have you priced the lower cas memory? for most uses, including reasonable overclocking you can't tell the difference real world.😉

I've read that slower latency memory may not run with faster latency timings, even when overall speed is dropped down.

I'd buy the lower latency memory. If you want future proof RAM, get the fastest PC???? you can afford with low latency.

There is no free lunch with memory 😛

Only problem is that Crucial doesn't sell any DDR400 with lower latency than 3.0 🙁

I might have to find another vendor with lifetime warranty and good quality. I'd say Corsair but thats overclockers RAM it would seem. (I don't need a heat spreader).

I have a 512Mb Crucial stick. It's spec'd at CAS 3, but it runs fine in my comp at CAS 2. Just try tweaking bios and you can definately get 2.5, and likely 2.0 w/Crucial. See this Tweaktown DDR400 review and this Anandtech DDR400 review.
