You're experiencing a mismatch between your RAM's actual speed and the settings in your BIOS. It seems the XMP profile is enabled but not properly applied during boot, causing the system to default to 2400MHz instead of the intended 3600MHz. Check your BIOS menu for any recent changes or updates that might affect XMP handling. Also, ensure your RAM modules are correctly seated and that you're using genuine Teamgroup T-Force XTREEM modules. If the issue persists, consider resetting the BIOS settings or consulting the manufacturer's support resources.
Uncertain about the quality of your memory controller. I faced the same problem you mentioned—using four 8GB DDR4 3600 MHz Corsair Vengeance LX CL18. When I started with two sticks, it performed excellently at 3600 MHz on an MSI B450 Tomahawk Max board. Adding another pair caused the same issue you described; after some investigation, it became clear my motherboard couldn’t support four sticks at that speed. To resolve this, I disabled XMP and tested the stable maximum speed, which came out to around 3333 MHz.
I believe that's it. After updating the BIOS and dealing with other issues, I figured using just two sticks would work fine. It functions perfectly. I wish I had tried this earlier. I'm a bit let down since it seems the board can handle 64GB at that speed. Thanks!
It's really sad that the motherboard guide doesn't give the full picture. I bought the 3600MHz RAM to boost performance, but I wish I had known earlier since in my area 3200MHz RAM is more affordable. It's odd how MSI doesn't mention on their page that using an M.2 slot won't work with the MSI B450 Tomahawk Max if you're using a 2 SATA port.
