Two different RAM speeds on a mobo?

I am still a bit confused about this even after reading RAM 101-My current mobo supports DDR2 533 (PC2 4200), and I have one gig of it. If I were to get another mobo that supported a higher speed, say DDR2 667 (PC2 5300) and I got a gig of that type of memory, would I be able to combine the two speeds on the new mobo to get 2 gigs of ram at different speeds?

If you did that then all the ram would run at the LOWEST of any of the speeds supported.

Sorry to have to bring this back up, but I went away. Which would be a better choice: 2gb @ 533 or 1gb @ 667? Would there be any compatablility issues with the 2gb setup?

its best to use just the 1gig of new ram and buy more off that when you can

if both types of memory are the same pins you can combine but your pc will run at the slowest ram speed

or become unstable.

more ram will TOTALLY outweight a higher speed ram. I'd take 2gb of the slowest ddr over 1gb of the fastest anyday.



ram is so cheap now anyways, just buy the fastest and upgrade the slower stuff later.
