Sims 4 Crashing in Live Mode 7/1/2024

@Sevreign  I think your RAM is probably okay, but I can't be sure because the ASRock supported memory list for your motherboard includes 20 different product numbers that start with KF560C40, all of which have a couple extra characters before the -16.  Here's the list, if you want to see for yourself:

There may be another part number somewhere on the RAM, or on the box or receipt or product page where you ordered it or the computer.

The RAM speed is fine these days—6000 MT/s is pretty stable overall.  However, your board's BIOS version is quite old, so much so that it may not include the updates that helped fix stability issues from when DDR5 was first released.  You can update to the newest release here:

If you do, skip the beta BIOS and go with version 13.06.  And definitely read the instructions before doing anything.  Flashing a BIOS is very safe if you follow procedure, not so much otherwise.

If you want to investigate the BlueScreens further, let me know.  But for Sims 4, if you're able to play with no crashes without any mods and custom content, and then adding mods or cc causes another crash, then the logical conclusion would be that the mods and cc are the problem, or at least some of them.  I'd suggest downloading a fresh copy of one mod that you're familiar with and that was specifically updated for the most recent patch (1.107), or at the very least explicitly cleared for it.  Start testing with a popular mod, as any issues would likely have been reported and fixed by now.
