Can I just add this ram in?

Bit of a noobie question but I've never used more than 4gb ram before.

I have two pc's one has 2x2gb G Skill Ripjaw and the other has some Corsair XMS 3 (again 2x2gb). I just wondered if I could just add 2gb of the XMS 3 into the pc with the Ripjaw in it?

Or does this have to be done in pairs? The other 2gb is going in a mame machine.

We'll need the product code/part number or a link to the XMS3 and ripjaws - as they do quite a few flavours in both ranges (especially the ripjaws) with varying voltages, timings and frequency.

E.g. the XMS3 could be 1333 MHz and the Ripjaws 1600 - but the voltages are the most crucial.

You can get the 'part number' for the memory using CPUz under the SPD tab.

Okay thanks, will have a look and post back...

Okay they are :

Corsair XMS3 4GB (2x2GB) DDR3 PC3-12800C9 1600MHz

and

G-Skill Ripjaw 4GB (2x2GB) DDR3 PC3-12800 1600mhz

Not quite enough info as there are ~3 flavours of G-Skill within that range -link - but it's enough info to advise you that it's possible to run the 2 sets together (if the XMS3 will run below 1.65V - which it should).

Run CPUz and get the part number of the G-Skill so that we can identify its timings and voltage - then i will be able to tell you which timings/voltages you will need to enter to marry up the two sets, so that they can operate together.

See above post firts

EDIT: You will probably end up with settings very similar to this:

1600Mhz (frequency)
9-9-9-27 (timings to match XMS3)
~1.5V (max voltage - will 1.55V to match G-Skill)
2T (Command rate )
