Kingston RAM different frecuency and latency compatibility

[FerLethal]

I have 2 modules of Kingston RAM DDR2 667 Mhz CL5 (KVR667D2N5/2G) and 2 modules of Kingston RAM DDR2 800 Mhz CL6 (KVR800D2N6/2G). I want to Know if i can install them together on a Intel DG965WH wich supports Dual Channel and wich will be their work frecuency and latency.

Thanks

I would recommend not installing them together, as it could cause instability and errors in your system.
Though sometimes some motherboards, would not even boot.

Even though its better to have them all equal, I only wanna clarify some of your questions:

1. Yes you can mix brands there's no problem with that.

2. You can mix speeds, though the faster one will work at the same speed of the slowest you have.

3. They should rise to the higher timings, but that will reduce performance (more noticeable on rendering videos, database servers, any memory sensitive application)

4. That's asking for troubles , you will end up forcing one or more modules to work at a higher voltage frequency that could easily lead to instability issues.
