Question Troubleshooting if ram is my problem

I have a new computer that I built that is experiencing some issues. What is happening is that at some point the pc either freezes or restarts. The timing is not consistent but generally happens fairly quickly after booting up. I suspect it is the ram as it is not listed on the mob qvl and I know Ryzen like faster ram. Could my problem be caused by something other than the ram? Is my ram incompatible with my build? I would swap out the ram to check but I don't have any spare ram.

Here is my build. https://pcpartpicker.com/list/j2fPr6
 
Very doubtful that it is the memory you chose to use. Those G.Skill sticks get used on plenty of Ryzen builds without problem, especially at that low speed. Lower speeds are LESS likely to cause problems than higher speeds. Yes, Ryzen LIKES faster memory, in terms of performance. NOT in terms of being easily compatible however.

Have you set the XMP profile for your memory in the BIOS?

Are your sticks installed in the A2 and B2 slots, which are the second and fourth slots over from the CPU socket?

DO you have at least the latest non-beta motherboard BIOS version installed? If you do not, then I would update to any version that is 7C02v15 or newer. After updating, I would do a hard reset of the BIOS as follows:

Power off the unit, switch the PSU off and unplug the PSU cord from either the wall or the power supply.

Remove the motherboard CMOS battery for five minutes. In some cases it may be necessary to remove the graphics card to access the CMOS battery.

During that five minutes, press the power button on the case for 30 seconds. After the five minutes is up, reinstall the CMOS battery making sure to insert it with the correct side up just as it came out.

If you had to remove the graphics card you can now reinstall it, but remember to reconnect your power cables if there were any attached to it as well as your display cable.

Now, plug the power supply cable back in, switch the PSU back on and power up the system. It should display the POST screen and the options to enter CMOS/BIOS setup. Enter the bios setup program and reconfigure the boot settings for either the Windows boot manager or for legacy systems, the drive your OS is installed on if necessary.

Save settings and exit. If the system will POST and boot then you can move forward from there including going back into the bios and configuring any other custom settings you may need to configure such as Memory XMP profile settings, custom fan profile settings or other specific settings you may have previously had configured that were wiped out by resetting the CMOS.

In some cases it may be necessary when you go into the BIOS after a reset, to load the Optimal default or Default values and then save settings, to actually get the hardware tables to reset in the boot manager.

Sorry for the couple month delay it sometimes takes me a while to get around to things.
I did the hard reset tonight and am still having the same issues.

To answer your questions after your post I enabled the XMP profile I tried both settings though one I did not do a hard reset on. Both of the memory sticks I originally installed in slots A2 and B2. I updated the BIOS when I first built the computer with a version newer than 7C02v15. In July I updated to the latest version.
 
Ok, so those are CAS15 latency memory modules. I would try going into the BIOS and changing the memory timings from 15-15-15-35 at 2400mhz 1.2v to 16-16-16-36 at 2400mhz 1.25v, and do it manually, not with the XMP profile. Leave ALL other memory timings set to Auto. Save settings and exit BIOS.

If that won't work, try 16-16-16-39.

Changing the memory timings has helped. At first I thought it had solved the problem but I still have the same issues it just takes longer for them to happen. I tried both 16-16-16-36 at 2400mhz 1.25v and 16-16-16-39 at 2400mhz 1.25v.

I think DB was on the right track,
I'd try 16-17-17-36, then 16-17-17-39, then 16-18-18-36, then 16-18-18-39.
For some RAM on a Ryzen system it seems to like a higher setting for those two for whatever reason.
Hopefully one of those will work for you, if Not I'd run memtest86 and make sure one of your sticks isn't faulty.
 
Before going through all that, try the timings I originally suggested by try changing the "command rate" listed in the timings to 2T. Since those are sticks with Intel leaning timings, they probably have a 1T command rate and Ryzen does not tend to like 1T command rate settings. If it IS on 2T, try 1T.
