looking to upgrade memory can I mix match?

Blitzilla28 · Apr 6, 2015

currently running 2x 2gb Kingston value ram ddr3, on msi870g45 Mobo,
i want to another 2x 2gb does the mhz ( frequency?) matters ? the brand? , On the mobo I have 2 Blue slots and 3 Black one for memory how do I setup the other sticks?

The brand does not matter. What matters is the CL value(latency) and the frequency. If you have, for example, CL11, like I do, you *can* put a CL10 RAM, but it is not guaranteed to work. Same goes for frequencies. These must match.

Hi Blitzilla28,
I'm Jewel with Kingston US Technical Support and would like to address your question. The MSI 870 G45 motherboard supports memory in Dual Channel mode. That means that you would need identical pairs of memory modules. So as long as the second pair of 2GB memory modules you get come as a pair or are identical then it should work. It would be better to get memory that is the same speed or frequency as the memory that you already have to be sure they will work together. But usually the system should be able to clock down the memory that is faster to match the slower memory. This is not guaranteed and it is always best to have all memory matching in the system to be certain it works well together.

Thank you for using Kingston memory.

Can glance through the forums of all the people having trouble 'mixing and matching', many of which using two identical model sets of DRAM. Mixing isn't a good idea as there are no guarantees mixed DRAM will play nice together.
