I'm looking to upgrade my current 1GB of RAM set up.
I have dual channel memory so my question is, do I have to have 2 of the same memory types or can I mix & match. i.e 2GB Samsung & 1GB some other make.
Thanks
its always better to have them in matching pairs. mixing will work but not as good. also if you mix 2 different speeds with dual channel the speed will default to the slowest of the 2. make sure you check what speed/size your motherboard can handle. if you are thinking about these make sure they will fit in your case as with the heat sink they are about twice the height of normal RAM units
I paid over £300 a little over a year ago for 8gb of the lesser 800Mhz 6400 and they are great. i run them at the max 2.2v but this required a bios update, changing the bios settings, timings and nb voltage.
good stuff
