I got a Maximus XI Code Motherboard about a year ago and used it with 16 GB (2×8) Crucial Ballistix DDR4-3600 CL16-18-18-38. Now I upgraded to 32 GB. The 3600Mhz are not availlable anymore so my local Computer Shop sold me 3200Mhz sticks. I asked if they would work with my already installed 3600Mhz sticks and they said yes. In fact, my Computer boots, but if I use more than 16 GB RAM my Computer crashes and reboots. My local Shop said, they would fix it for around 70 bucks. Does anyone know a Solution to this Problem? Debug Code F6 or Fb is shown for about 3 seconds, then the post process continues. I got the 3200 sticks both in channel A and the 3600 sticks both in B.
My CPU is a Core I9 9900K and my GPU a Rtx 3060.
