My Asus P5QL has 4 RAM slots, 2 are coded yellow and 2 black where you put ram in pairs to work optimally right.

So I bought some new 1066Mhz ram (2 x 2GB) and it worked great, I was wondering if I could put the old ram (667Mhz 2 x 1GB) in the remaining black slots.

Would I lose performance, would my fast ram downclock? I thought for some reason it would be fine be I am pairing ram in their pairing slots.

Thanks

AFAIK, if you set the mobo to autodetect it will downclock everything to the slowest speed.

If you manually set the memory speed, the slow RAM may choke and/or die and the PC won't run correctly.

RAM is paired for dual channel operation ONLY. All of the memory is on the same memory bus.

Also, the voltage might be different...if this is the case then some of the memory will be underpowered or overpowered. Either way it is a bad thing.
