Can I mix 2 different memory cards on my computer? Eg one is 256 %26amp; the other 512?
Absolutely. Ideally, you'll want to make sure it's the same frequency though. (look for mhz). If they're not the same frequency, some motherboards will still support them, but that will slow both chips down to the slower speed.
Reply:yess you can have a mix of ram interms of capacity


but the type i.e. DDR I and DDR II cannot bhe mixed





incase you mix the ram spped it does work but as far as possible try using RAM with same speed
Reply:As long as they are the same type like DDR2 677 then yes. I have one 256 MB and one 512MB
Reply:No you can't. They must be installed in pairs for them to work


- 2 - 256K's %26amp; 2-512K's otherwise the motherboard will ignore one of them.
Reply:The size of the ram is not as important as making sure that the ram is compatible.. Put the larger chip in the " First Slot" or area accessed by the computer first and then the smaller chip in the secondary slot..





You need to know that the ram is compatible with the computer and with it's self.. you shoudl find that in the motherboard specs from teh company that made it.. and you need to know that it can actually handle that much ram.. ** don't put more in then the manual says the computer can handle.. it just won't work.. **
Reply:memory?


you mean ram?


if so, then yes.


i currently have 2 512's and 2 1 gig's = 3 gigs in total.
Reply:yeah you can.. it will read both of them...
Reply:This is base on your mainboard.


if Dual: 2 memory card must be the same.


If not Dual: the total memory is sum of eachs, that is 256+512=???
Reply:You should be able to add this memory card to your computer. This will work if they are the same kind of memory: pc100, pc133, DDR, etc. If one of the cards is ECC memory and the other is not, this will not work.
