Anyway im just wondering if you need to use the memory standard for a mobo, for instance im looking at one that says DDR3 2133, can use lower or will it not work? aslo if the memory say Specifically Designed to compatible with Intel Core i5 and Core i7 for Intel P55 motherboard can it work for AMD?
Normally there is alot more info than one memory speed. The motherboard manual you can usually get online should have a compatible memory list. If you give us the exact manufacturer and model someone will probably look it up for you.
The "core i7" compatible stuff just indicates it is low voltage RAM that will work on a p55 or x58 motherboard. As far as I know it will also work on an AMD motherboard, though you may have to set the memory settings manually in the bios.
