Memory Sticks "cross compatible?"

Hello LTT Forums Members,

 

I'm looking at upgrading some of my PC, since technology is progressing so fast. The RAM I have installed is two sticks of G.Skill Value RAM at 4GB a stick, so they're not worth much to sell. I'm going to try to buy two more 4GB sticks, since GSkill Value is so cheap, but they may have different clock speeds. Is it OK to put 2 1600 MHz Sticks in with two sticks of higher clocked memory? Can I add in two 8GB sticks with my two 4GB sticks for 24GB?

you CAN mix-and-match different RAM dimms and often they will work ( but they run at the speed of the slowest ).
But it's not recommended, sometimes it will even DEGRADE performance, so you'd have to try if you get a benefit.

watch out that you put 12 gigs in both channels, to get dual channel performance and watch that your cpu supports 4 sticks.
