Hi, yesterday I posted after moving my PC, which caused my CPU cooler to shift and triggered a CPU LED. But the problem wasn’t coming from that.

The issue is actually with the RAM.
I have 4 Corsair LPX sticks, 8GB each, CL16-20-20-38 (had to use low-profile RAM because of a Noctua NH-D15). The thing is, two of them are 3200MHz and the other two are 3000MHz, which I bought a year later when I wanted to upgrade to 32GB.

I know mixing different frequencies can cause issues, but it had been working perfectly fine for 2–3 years, and suddenly it doesn’t work anymore.

When I install the 2x8GB 3200MHz sticks in slots 2 and 4, it works fine.
When I install the 2x8GB 3000MHz sticks in slots 2 and 4—or any other slots—it simply doesn’t work at all.

Do you have any ideas to help me? I’m stuck, and considering the price of RAM, I can’t afford to replace it right now.

Thanks.

Hello, I moved today… and when I turned my PC back on, I noticed that my CPU cooler had shifted by about 3–4 degrees toward the RAM. I tried to start it like that, but the CPU LED lights up.

I then tried removing it and reapplying thermal paste, checking the CPU in the process, and it looks perfect — no bent pins at all. But the CPU LED is still on.

Do you know where the problem could be coming from?
