Hello. First a little background. I have a asrock z77 mobo that had 8 gb of ram in the form of 4, 2 gb sticks. Last night my computer turned off suddenly and when it tried to reboot I got error 55, which is a memory error. It would turn off and turn back on, and then turn off again a few seconds later. If I let this happen enough times it would eventually boot fine, and then anywhere between 15 mins to an hour later it would shut down again, give me error 55 and turn off and on every few seconds.
Through troubleshooting (taking all the ram out and putting it in one stick at a time) it seems that I have found the culprit, one of the sticks has gone bad, even though memtest said everything was fine. Now, since my mobo only supports dual channel, not only did I have to take out the offending stick of ram, but also another to keep the dual channel setup. So now I am down to a sad 4gb of ram which is just not ok.
Finally, here is my question. For a dual channel setup, all 4 sticks don't have to match, right? Only the sticks in A1 and B1 have to match, and the sticks in A2 and B2 have to match. Is this correct? If so my plan is to purchase another 8gb of ram in the form of 2, 4gb sticks for a total of 12gb ram and put them in my currently empty A2 and B2 slots. Before I hit purchase on Newegg I want to make sure that the research I did was correct. Thanks.
