Hi All,
Since I started this topic, I owe all the contributors an update on how my problem was resolved.
I had to buy a new motherboard, because the one with the RAM slot problem was damaged when I was mounting the cooler multiple times. The cooler had a bad design for secure mounting to the motherboard, which lead to scratching the surface of the motherboard and ASUS/Intel decided to put copper traces just under the mounting area. So the traces got scratched and presumably damaged. Motherboard retailer refused warranty.
The reason for mounting the cooler multiple times was that the cooler's pump was broken out of the box so PC was overheating right away, but I did not know that at the time, since cooler has no separate pump rpm senson, so I thought it was my wrong mounting that caused the problems. I got annoyed by this cooler and bought a different one that has better mounting design.
So overall, an expensive ride - one damaged motherboard that I had to replace and one cooler that I replaced with a different brand fearing it would break the new motherboard.

One possibility for a bad memory channel is a bad CPU mount. Either pin damage, uneven pressure, or too much pressure from the cooler.
The Intel LGA1700 clamping mechanism is essentially a bad bit of engineering design. You may wish to investigate the replacement "contact frames" which clamp the CPU with much more distributed and even pressure. Thermal Grizzly do probably the best one, or there's Thermalright with a more budget version. See various videos on YT for details, such as der8auer, Gamers Nexus, and Jayztwocents, amongst others.
Jay also did a video on too much cooler mounting pressure causing pin contact problems.
It could be a problem with the CPU or board, but a mounting problem is more likely (and can be an easy fix). Remount, carefully inspecting the extremely fragile pins in the socket, and don't clamp the cooler down excessively.

I would stick with the recommended screws, just don't go after every last thread when tightening if it gets tight before the threads run out.

Hello,
I have just made a new PC build using ASUS ROG STRIX Z790-A GAMING WIFI D4 and 13600K with Arctic Cooling Liquid Freezer II 280.
After lots of boot issues and A/B testing I found that 2 RAM slots A1 and A2 (the first 2 from the left side) are not working and the PC will not boot if a RAM stick is plugged into any of these slots.
The sequence of LEDs is like so: shorter CPU, longer RAM, shorter CPU, longer RAM,... after few cycles only RAM LED is on and nothing else happens.
The 2 RAM slots on the right B1 and B2 are working fine and I have 2 sticks of RAM plugged into them.
The result is that I only have single channel enabled.
While trying to solve the problem, I updated to the latest bios 0703 (issues present since at least 0502), ME firmware, did CPU and RAM re-install countless times. With 2 sticks in B1 and B2 slots I started up Windows just fine and I ran some stability tests for few minutes. All seems fine.
But I would like to have A1 and A2 also working.
If there is anything I can do, please let me know.
Also, please let me know if this is a hardware issue. Is it the motherboard or the CPU which needs to be RMA-ed? Or both?
Cheers,
Marek
