Carefully remove the CPU cooler, remove the CPU, and check the motherboard for any bent or misaligned pins, if everything looks good, reinstall the CPU and try again.

It's possible the new cooler is pushing harder on the socket than the old one and in combination with either a bent pin or slight misalignment of the CPU in the socket, it's causing one of the memory channels to drop out.

The memory controller is on the processor, and the pins in the socket just link directly to the pins in the DIMM slots. If both sticks are good, but one of the slots is dead, it's likely a physical connectivity issue and the socket pins are the first thing to check. I have seen a couple of processors in my time with dead memory controllers on one channel but we're talking two processors EVER and I've dealt with thousands, so it's super rare IME.

If all the pins are good and the CPU seats nicely in the socket, did you maybe slip with a screwdriver when installing and scratch the motherboard near the socket? I've seen machines people brought to me to fix where they'd gouged the board with a screwdriver when installing something and destroyed some of the traces.

The last thing to check is that you haven't dropped a screw down behind the motherboard and it's shorting out some of the pokey contacts behind the DIMM slots. The CPU would detect that as an issue and shut down that memory channel, if it even POSTed at all.
