The short answer is no, they aren . They physically won even fit in each others memory slots on the board because the notch in them is in different places.
The short answer is no, they aren’t. They physically won’t even fit in each others memory slots on the board because the notch in them is in different places. The geek answer involves comparing speeds, pin counts, and a lot of other specs you probably don’t care about. You can compare some of the specs here: http://www.ddrsdrammemory.com/ Within it’s own type, memory is ‘backwards compatible’. Meaning a faster speed of DDR, such as DDR3200 will work in a pc that says it needs DDR2700 because memory will slow down. Same goes for DDR2. The opposite is not true, however. If you were to put DDR2700 into a computer that uses DDR3200 it would burn out (possibly literally). If you have a specific make/model of computer you are looking into feel free to send me the info and I can send you recommendations for memory.
