I have an MSI B450 Tomahawk motherboard, I attempted upgrading RAM from 16gb T-Force Delta @3000mhz to the Corsair RGB Vengeance Pro SL @3600mhz, and once i switched them out my computer did POST.

I then went to apply A-XMP to 3600mhz, after that it let me sign in, then i got a blue screen and it refuses to POST with that ram in it now. The only signs I got was the red mobo LED for my CPU, I assumed that since its only a Ryzen 7 2700x that the max power is around 2400mhz for ram, however i cant even underclock the new ram because the computer will not display at all, any tips? How can I reset the clock speed of the ram with my CPU rejecting it?

Build: MSI B450 Tomahawk, AMD Ryzen 7 2700x, MSI RTX 2070 super

Ryzen 2700x officially support up to 2933mhz ram, although many can support 3600 ram. It's just a matter of how (un)lucky you got with your chip. I'd do what rgd1101 suggested and find the jumper to reset your bios, load the xmp profile but then manually set the frequency to 2933 and see if it boots. If it does, you can then experiment rebooting and raising the frequency until you find where your 2700x craps out. I think almost all 2700x chips should reach at least 3200. Also make sure you're running the latest motherboard bios for your cpu. A lot of bios updates relate to memory compatibility. Just be careful if you do update your bios. With the release of the 5000 series Ryzen chips, many motherboard bios's remove support for 1000-2000 chips. Make sure you pick the latest bios that still supports the 2000 series chips.
