Third stick of ram causes computer to not boot

[vhunter]

So a while back I posted this:
http://www.tomshardware.com/answers/id-2153557/upgrading-4gb-ram.html
Now that I received the ram when I installed it and the computer did not boot. I tried many combinations keeping the two 2gb stick in the same channel but non of them worked. I also did a memory test on all the ram and they all passed. Doesn't help that the motherboard manual doesn't say anything about odd number ram sticks. as stated in the posted thread motherboard is an MSI P67A - G45 B3. Is the only solution buying another 4gb card?

it doesnt boot with 3 sticks because the system requires pairs (2 of each) to properly work...imagine a 2x4gb or a 2x8gb or a 2x2gb etc...


since you motherboard is dual channel (4 slots to fit ram in) you can either have 2 slots filled or all 4

So qwertyDS's response from my previous thread was wrong?

there are a few intel tri channel motherboards and it looks like yours is not one

well that would depend on if he knew whether your mobo is dual channel (has 4 ram slots) or not....

the only solution would be to get another ram stick

Oh well guess I'll just order another one, thank you all for the support.

see now you into mixing ram instead of getting a matched kit to start with --- not saying it wont work but theres now that risk of instabilty-- the single stick ram is more than likely ones that did not bin for use in a matched kit [opinion]
