Mixing CAS Latencies?

[pseudonymm]

K, So I had 2x2GB sticks in my motherboard. They were DDR2-800, standard 5-5-5-15 timings... Recently I got 2X1GB sticks... they too were DDR2-800, but they were rated as having 3-4-4-12 timings. I was wondering if this was a problem, or if maybe I should put them in different channels or something...

But my rating for memory went down in Vista... that didn't make sense to me...

Tnx for the help.

all memory will run at the slowest timing I believe

you should check the settings in the bios and see what your motherboard is doing with your ram.


The vista score... no idea

Exactly.

Especially when mixing kits i'd like to be controlling speeds/timings/vdimm manually.

You can use CPU-Z & MemSet to check details in Windows.

All of the sticks should run at 800/5-5-5-15. If CPU-Z confirms this, you're fine. Don't worry about the Vista rating - it doesn't mean very much.

So I have an older PC that takes up to PC3200. I have one stick that is CAS2.5 and two sticks that are CAS3. So if I set my BIOS to CAS3, it should run ok, right?

It should be fine.
