I'll try and let you knowJust reset bios to factory defaults and let it boot again, it should retrain memory

I’m checking right now and there is no “factory reset” option. There is a “Load Optimized Defaults” option. I did it but RAM frequency still show 5200 and there is no way to change it from the BIOSJust reset bios to factory defaults and let it boot again, it should retrain memory
Try to reseat the memory, swap the modules around.I’m checking right now and there is no “factory reset” option. There is a “Load Optimized Defaults” option. I did it but RAM frequency still show 5200 and there is no way to change it from the BIOS
About microcode update, this is what I get:I would do a bios reset and see if it trains to 4800 MT/s after the reset.
And update microcode:
...
7) You can check what microcode you are running after reboot by grep 'stepping\|model\|microcode' /proc/cpuinfo

I'm running memetester with 48G option, I tried with 96G option but couldn't do it.Yes but let it run several times.
Latest version is 0x411cAbout microcode update, this is what I get:

Thanks, I will update it after memtest and see if it solve the random reboot.Latest version is 0x411c
Yeah me 2...i also ordered a 96GB crucial kit. great. now i'm in doubt if i should cancel / get a 64gb kit instead
Nope, same problem. System hung himself. This was the error I was able to grab:No error within memtester with 48G option.
Updated to latest microcode:
View attachment 34787
Now will see if random reboot happens again.
Will keep you posted.
