Hello !!

I have a Tyan Tiger K8W S2875 dual opteron mainboard (4 DIMM slots in total)

I'm planning to buy new memory, and I have some questions:

1 - I would like to add 2 GB of memory to my system.
Is someone using these memory sticks in pairs ? :
Corsair CM72SD1024RLP-3200 (1GB DDR 400) x 2

2 - I already have these modules installed:
Kingston KRX3200AK2/1GB (2 modules of 512 MB DDR 400)
The main question is: Would the system work fine with Corsair and Kingston put together ?
I know I could buy Kingston's modules, but are much more expensive than Corsair.

3 - I also saw new modules of 2 GB DDR 400 by ATP, model ATP P/N: AB56L72Z4BFC4M
Is someone using them ?

THANKS A LOT for any help about this !

I heard from one man, he use it on Thunder K8QS Pro (S4882) (4xOpteron)
It is dual rank dimms

They have different timings and MBs.
It is not good idea, imho...
