GSKILL RAM Breaks Two ASUS Motherboards! DIMM Bay's 4 and 5 no longer working on both!

MB1- Asus Rampage II Gene
MB2 - Asus Rampage III Formula

RAM - 6 x 4GB - GSKILL F3-12800CL9S-4GBRL

I put it in the first board, and detected only 16 GB RAM, though memtest detects all the DIMMS in all the bays.

I tested the DIMMS and the bays, and determined that the RAM was working, but the last 2 of 6 bays were not.

A few days later, because the RAM was slightly faster than the 3 x 8 GB sticks that I had in another MB, I made the swap.

Once again, only 16GB RAM detected. I had a bad feeling at that moment that this MB would also never detect 24 GB again as well, but it seemed so hard to believe. I'd never even heard of anything like that before in close to 20 years at this.

My experience be damned. This board appears shot too. I need every 24 GB of this RAM for my use case, so now it is useless to me.

WTF!

Any help is much appreciated.



EDIT: One correction to the above: I also had it in a Asus P658XD-E, which is also now doing the same! This has become a nightmare.

The insanity continues! I found this youtube video: https://www.youtube.com/watch?v=R_9MwkZ8cjs

That's not the solution, but one of the comments is!

"The problem is only one thing. The CPU cooler when fixed to the motherboard. Is bending the ZIF or the motherboard circuitry. The is exactly the issue if your ram is showing in CPUZ in its slot under SPD and not in bios. Its a massive flaw on these boards and has driven me crazy for years only on my own builds as I would not supply any these boards to a customer. Asus are keeping quiet abut this flaw. DONT wast your time in the bios just turn the pc off and press the cpu cooler when booting. Sometimes it works sometimes not its a f*cking farce.. Your best buying 2 large memory modules...

The only reason I haven't marked this as solved is because I'm sure the moment I do it will pop up as 16 again, requiring another push, indicating that something has been physically altered on the mb.

As I replied to his comment:

"... On two that I have in front of me today, I was able to correct the problem by pushing down on the CPU HSF during a boot once.

However, I still think the make/model of the RAM has something to do with it,. because I had 6 sticks of other (better) gskil RAM in two of them already, and it did not trigger the issue.

On the other hand, these six DIMMS cause the issue every time, on both of the boards I have left, and they will also never work as 24 GB, always only 16.

When I put the 3 8 GB gskills dims in, they once again register as 16 GB, but a push on the HSF when the MB is off corrects the issue for those.

I'm not an hardware engineer, but I suspect there's more to it than simply stresses on the PCB, based on that."

In other words, I think it's something about this 6 DIMMS. Others may cause it, but I'm almost sure that it's a minority.
