I run into a strange issue with my PC when I enable XMP.
Computer won't boot the first time I press the button. Fans spin, CPU LED on motherboard stays on and no boot. If I press the reset button on the case while my PC is in this state it boots normally and have no problems afterwards. After a shutdown however the problem comes back.

Experimenting a bit I found out that if I run my memory with XMP and at lower frequency (3000Mhz) or if I only use two sticks at the advertised frequency (3600Mhz) the issue is resolved.
The memory I'm talking about is the Kingston Fury Renegade KF436C16RBK4/32 kit of four.
My other computer specs are:
  • CPU: Ryzen 5 3600
  • GPU: ASUS RX 6650 XT
  • Motherboard: MSI B550-A PRO
  • PSU: FRACTAL DESIGN ION+ 2 650W
I also tried increasing dram voltage to 1.39V and soc voltage to 1.2V but it didn't work.

Now, I've read about problems that may arise when four sticks of RAM with XMP and Ryzen that require some tinkering with timings but I don't know how to do that.
Should I just return the 4x8GB sticks and get 2x16GB ?
