This is OT but since its been brought up....
In
theory running four sticks on a dual channel rig is no problems. However, just like the 1366'ers and running 6 sticks on triple channel it can cause issues. It can also limit some overclocking ability. BUT even for normal peeps needs, four sticks can - from time to time - cause some wonky issues to pop up. It is rare and most people
never have issues, but it does happen. Especially when a newcomer purchases two dual stick kits and didnt configure them properly in the BIOS. Even when properly configed it can happen.
Hell my test bed - and it looks to be that same mobo as the OP - ran into issues with Mushkin and then GSkill....but loved Corsair that I fed it. All 8 sticks tested fine and are working perfect in other rigs...but not that particular mobo. Just like in the old days the very first thing I do when TS'ing and tracking down memory related gremlins is pull two sticks. IF the problem goes away...it was the sticks not playing nice (assuming that the test fine on a dif rig and its not just a dead stick or dead ram port on the mobo). IF the gremlin is still there. Pull another stick and try them one at a time. Classic computer trouble shooting 101.
To the OP sorry to hear about your H100. Corsair are good peeps to deal with and will make it right. In the mean time...yeah that air cooler you have chosen to replace it with...is a beast. You will love it.
