Let's see, I have currently 128 RDRAM PC 600 on my comp, I'm going for 384, but I can't seem to find any 600s in my stores... AND NO, I am not going to buy from on-line.

The only RDRAM most stores I see cary are 800

I know my HP mother board can support either 600 or 800, but can I mix them? For example put a 128 PC 800 in slot A1 and B1, and put 64 PC 600 in A2 and B2?

Any specific brands I should look for or avoid?
