timing matching question

post #1 of 4
Thread Starter 
Hello ladies and gents:


I've got http://www.newegg.ca/Product/Product.aspx?Item=N82E16820145224 (6gb triple chan. cas 8 , timing 8-8-8-24 )

If I want to add more. does matching the latency and timings matter?

From what i've gathered so far, if mixed the memory will operate at the slowest speed? If that is true how drastic of a difference are we talking if lets say I added some cas 9 timing 9-9-9-24??

thnx in advance

Some people will tell you it matters - but from my experience, you can add some 9-9-9-24 DIMMS in the other 3 sockets along with the 8-8-8-24 DIMMS, and it will run just fine. The CPU will access the CAS 8 and CAS 9 banks separately, and that ends up meaning that some memory requests will be faster than others. In the long run, I doubt you'll notice, and there should be no stability issues.

Mixing and matching timings within the same 3-module triple-channel bank however would be bad.

If it were my machine, I'd get another 8-8-8-24 kit just to keep everything the same.

agreed I would't mind matching it but I use newegg and they don't sell matching sticks (timing wise) anymore, this stuff is startin to get old I guess biggrin.gif
thnx for response

The results are mixed... I just made a recent thread on this too... The last paragraph is the one for you OP...

But feel free to read the whole thing!
