DDR3 RAM, all i7 or socket 775 compatible

theCzar

I'm upgrading my processor to an Intel Core™ 2 Quad (have old dual core) with bus speed of 1333Mhz so I want to move from my current 2gb 1066 Mhz DDR2 to 4gb 1333 DDR3 to take advantage (my Gigabyte mobo has slots for both)

I've been browsing around Komplett and see lots of DDR3 RAM, but much of it claims to be for i7 boards. Am I right in presuming that as long as its DDR3, it will work in my DDR3 slots, even if my mobo is socket 775 and not i7? Or do the i7 boards require something of the RAM that makes them backwards incompatible?

The i7's have triple channel support, so a lot of the DDR3 kits come in sets of 3 to take advantage of that. It should be fine otherwise.

Voltage is also a factor, something I learned the hard way recently. Basically, i5/i7 boards are supposed to only supply a max of 1.65V to the RAM. That's probably why you might see a set of 2 with i5/i7 in their description.
