I tried each ram individually and neither would boot running xmp. I then tried them on my brothers pc running the same cpu and motherboard and it worked on his. I tried him ram on my pc and it would not work running xmp. I think this is the cpu.]]> Fri, 19 Mar 2021 07:01:31 +0000 https://forum.asrock.com/forum_posts.asp?TID=18402&PID=84761&title=boot-issue-when-xmp-enabled#84761 https://forum.asrock.com/forum_posts.asp?TID=18402&PID=84744&title=boot-issue-when-xmp-enabled#84744 Author: Xaltar

If both RAM modules pass, try them again in dual channel (A2 and B2 slots) and see
if that works. If not, RMA the CPU.]]> Thu, 18 Mar 2021 03:13:59 +0000 https://forum.asrock.com/forum_posts.asp?TID=18402&PID=84744&title=boot-issue-when-xmp-enabled#84744 https://forum.asrock.com/forum_posts.asp?TID=18402&PID=84743&title=boot-issue-when-xmp-enabled#84743 Author: Xaltar

It sounds like your CPU IMC degraded and now can't handle 3600 at the RAM's XMP
settings. XMP = eXtreme Memory Profile, basically a built in overclock saved in
the RAM's firmware that works on most systems.

You can try manual settings, take a look for a good Ryzen RAM overclocking tutorial
using Ryzen Calculator (a free app).

If that doesn't get you up and running, you should contact your retailer and
try to RMA the CPU. The likelihood anything else is causing the issue is slim.
If the system began working with XMP then stopped its either the RAM or the CPU
that has degraded. I would lean toward CPU but you can partially rule out RAM
by installing a single RAM module in slot A2 and try enabling XMP. If it works,
try the other module in the same slot and repeat. If only one fails, return the
RAM, if both do, return the CPU.]]> Thu, 18 Mar 2021 03:11:46 +0000 https://forum.asrock.com/forum_posts.asp?TID=18402&PID=84743&title=boot-issue-when-xmp-enabled#84743 https://forum.asrock.com/forum_posts.asp?TID=18402&PID=84742&title=boot-issue-when-xmp-enabled#84742 Author: cheesecake

I have a Razer B550 paired with 2x16gb Trident Z Royal 3600 ram. It was working fine for a few weeks but suddenly I had issues where the pc was non responsive every morning. I tried a fresh Windows reinstall and now when I try to set the ram to 3600 xmp, the pc will not boot and shows the code "C0"

It seems like the pc will only run when the ram is set to auto. ]]> Thu, 18 Mar 2021 01:28:27 +0000 https://forum.asrock.com/forum_posts.asp?TID=18402&PID=84742&title=boot-issue-when-xmp-enabled#84742
