Can I mix 2x256 & 2x512 RAM cards??

Can I mix 2x256 & 2x512 RAM cards?

And if I can, will I still have dual channel support?

I have 2x256 DDR RAM PC7500 and 2x512 DDR RAM PC750.

My computer can hold up to four RAM cards.

It is a HP and it came with 2x256. Now if I will lose dual channel support

Is it better to just have 2x512 or is it better to have 2x256 and 2x512,

And if I use both 512 and 256 should I alternate, 512, 256, 512, 256 or 256, 512, 256, 512

Or should I not alternate, 512, 512, 256, 256 or 256, 256, 512, 512.



Please let Me know

Yes you can but it will run ongodly slow. You dont want no more than 2 ram cards in your PC at one time.
