RAM stopped working in dual channel

My PC has been fine for almost a month but all of a sudden I'm in an endless boot loop if I put my memory sticks in a dual channel configuration. Is it my RAM, CPU, Mobo, ect?
 
Solution
Well, damn! Only thing i can think of is you should try to disable XMP, but i guess that should be off by default if you resetted the CMOS.
Sounds like a busted memory controller. Did you overvolt much on those failed overclocks?


You probably have memory sticks that can't do dual channel. Don't sweat it, though. It's not that important. Capacity matters more.

Well, I bought a dual channel kit. Could it just be they're just faulty sticks?
 


I would RMA it if it works in different channels but not dual channel. Very strange. What brand are they?

Yes. Let me tell you what happened. I had overclocked the CPU and it failed to post a couple times but I fine tuned the OC and it worked fine. Only after that the problem with the RAM started.
 
You'd think it's obvious that one should mention overclocking as part of teh equation :))
It's possible that the overclock isn't sitting right with the memory controller. Take it down a notch.

Anyway, memory troubleshooting should always be done at stock speeds ;)

Alright. I'm not home right now but I'll try it out in a couple hours :)

I tried all slots for the RAM in every combination. Any dual-channel config ran into problems. I have the Pentium K and a Hyper 212 Evo

Might be the EVO, many try and tighten coolers down as much as they can, not a good idea. Try loosening the cooler and then snug down to screw tight and try. If too tight in a corner or side it can throw the CPU out of level and not get full contact with all pins, effectively, you can 'lose' a channel

I'll try that. I'm just curious, would it be bad if I tightened the cooler while the case was upright? My desk is small and it's a hastle to flip the computer.

So, I turned down the overclock so I don't have to change the voltage. It's still occuring. Would having no overclock at all change anything?

I did that. Didn't solve the issue. I should add that this problem only started happening after I applied a couple failed overclocks.
