CPU Cooler Caused Memory Issue

[Jwpanz]

I wanted to ask around, and also inform others, about an odd issue I ran into with my Hyper 212 Evo. When it was installed, I could not get my memory to work in dual-channel. I had to put two sticks into single-channel. I thought my A channels were dead and nothing I did worked. However, when I took the cooler out and installed an H100i AIO, I just thought I would try to use the A channel and voila! It worked.
This leads me to believe that the Hyper 212 Evo was causing some sort of issue. I noticed that one of the standoff's for the cooler was missing the coating and figured that it may have been contacting and shorting leads from the A channel on the motherboard.
Has anyone else had this problem or currently have it? It just seems like such an odd problem to run into.
Just to note, I did think the cooler was tightened too much and tried loosening it but it did nothing. The change only happened after removing the cooler itself.

When coolers are installed too tight or tightened unevenly , it can cause the memory slots to not function , I have come across this several times.

I agree that if the CPU cooler is over tightened or not tightened evenly it can cause this issue. There have been a rash of issues with the Hyper 212's lately of being over tightened and having both Ram and CPU issues due to the traces in the board around the CPU socket being bent/deformed and losing connection.

This can happen with any cooler and not just the Hyper 212's but seems to happen more often on motherboards with thin PCB's. Thin PCB's allow for the board to be more flexible than the thicker ones.
