Can Theses RAM Be Used Together?

forceuser98 · May 28, 2015

I have some spare 4GB of RAM (2x2). I already have 8GB (4x2) in my computer, and four RAM slots. Can all of these be used together to utilize 12GB?

What's the specs and speeds of the memory, and what is the model of your motherboard? Larger DIMMs should be populated in the first channels, with the smaller in the second.

Since you have them, give them a try, I'd go the 2x4GB in slots 1-3 and the 2GB sticks in slots 2-4, let us know what happens and if any problems let me know mobo, CPU and the DRAM model #s and we'll see if we can get them to play nice

It'd always wortha shot.... the more things that are the same (module manufacturer, speed, CAS, voltage, etc), the greater the liklihood of success. Your MoBo manual will instruct you what goes where....

Put 4 GB in slots designated for 2 sticks (primary slots) .... add the 2 GB ones to the secondary slots

Saberus :

______________

Channel A is normally slots 1-2 from CPU while 3-4 compose Channel B. You want an equal amount in each channel so a 4GB and 2GB in slots 1-2 and same in 3-4. If you put 4-4 in 1-2 you'll have 8GB in channel A and 4 GB in channel B - far from optimum - that would be in flex mode with 8GB total runing in dual and 4GB running in single

I wasn't being clear, I meant to say the larger DIMM should be the first one in the channel as you state. I realize in my haste I said almost the opposite.

I wish manufacturers would be consistent.... different manufacturers have different preferences but even within they change things up.

I was doing an Asus Z97 build last year and because we had so many builds happening that weekend, I was at my work desk with one.... my son came up and said i had the RAM in the wrong slots on the new build and I looked at my Z87 M6F and said ..."See Asus does it this way"..... sure enuff the MoBo manual said different. I lost the bet and it cost me having to do the Windows / driver install and WU on the build I was doing as well as the one I was doing.
