Question base 64k memory failure - G.Skill 2x8GB 3000 MHz, MSI B350M Gaming Pro


Jan 7, 2014
Hello everyone. Yesterday my system booted up without beeps and it showed 8.00GB RAM (7.95GB usable) (instead of 16.00GB and around 16.00GB usable) in PC specs. I updated the BIOS, and it was fixed.

But today, 10 minutes ago, display suddenly showed no signal while PC was running, i heard no beeps and red led turned on MOBO(MSI EzDebug) and it said RAM was problem. I restarted PC and it beeped 3 times. In MSI MOBOs that means "base 64k memory failure". Now i have just 16.00GB (7.95GB usable) showing in computer properties. RGB lights work as normal*.

Is one of my RAM modules dead, is it damaged or something else? Did RAM slot die, is it MOBO fault? How can i diagnose what is the problem?

My specs:

Ryzen 5 1600 @ 3.2GHz (stock)
MSI B350M Gaming Pro
G.SKILL Trident Z RGB 2x8GB 3000MHz (running at 2933MHz, XMP mode on)
Gainward GTX 1070 8GB
Patriot Blast 240GB
2TB HDD Toshiba
31.5" 1440p AOC monitor

All drivers and BIOS updates are newest.
* - when there is problem with RAM(few times it dropped to 2133MHz), RGB behavior can't be changed, its just stuck on default rainbow mode. I ussualy update BIOS, or check if XMP is on, after that it goes back to 2933MHz and after that i can change colors as i wish
