Overclocking on B350 Pro4

However it doesn't consistently apply the profile. I went into the UEFI on the OC tab and manually set the speed to 3700 and the voltage to 1.3, and the machine refused to even post. Am I missing something here? This is my first time, but it seems fairly straight forward for modest improvements. System specs R5 1400 8gb DDR4 2666mhz BIOS is 2.6

What version of Windows are you using?

For manual over clocking in the UEFI, try using a VCore of 1.35V. Your board's manual is not up to date with the new UEFI versions, so I cannot tell what new options you have. Do you have a VCore mode of Offset, and an LLC option? If so, try using Offset mode, at 1.325 - 1.350V, with LLC at 1 or 2.

You can also try setting Cool n Quiet to disabled, and C6 Mode to disabled. Set SVM Mode to disabled.

It's possible that your memory is border line compatible, and the CPU OC causes it to fail POST. What model of memory are you using?

I don't know what problem Ryzen Master has at times. The latest AMD chipset drivers can be found here:

Your board has a new UEFI version, if you want to try it:

as above really
try the cpu overclock at dram set to 1.35 and the timings exactly what the team ram quotes
i get 3.9 on 1,3 volt cpu (but it would seem im lucky to get it at that low voltage)

to sum up i think your pushing the under volt a little too hard, i would definatley leave the dram at 1.35 myself

have you tried disabling the ram overclock entirely

just to check the ability of the cpu overclcok alone ?
i mean literally setting it at 2133 stock while you test the cpu

i done a system overclock last night with a b350 and ryzen 1600

weirdly enough the ram overclock was insanely easy and extreme 2400 ram clocked to 2933 !

but the initial cpu clock to 3,8 forced a very hard dead pc (needed power down and cmos clear to do anything , even to try and post )
we resolved it wierdly enough by trying a basic schoolboy noob attempt
we literally just slid the multi to 38 and left everything else at auto
guess what instant boot and stable ...go figure !

yet it locked up with volts set nice and cool n quiet etc disabled before that..............

Not proud that I'm reviving a 2 month old post.. however I finally did that (reset UEFI to default) and set speed to 3700mhz and voltage to 1.35 and the same thing happens. Save & exit > pc hangs until I use the jumper to clear the bios. Tried again at 3500mhz with same voltage and happens again. What could be going on? My bios is 1.06 agesa (non-a or b versions)

I've not tried p-state OC. I looked in those settings and was thoroughly confused lol. Could it a UEFI issue, requiring an update to 1.06b? As far as voltages, this board requires you to set them and has no auto option that I've found. For what its worth, Ryzen Master seems to overclock to 3.7 @1.325v, however that doesn't seem to apply consistently (i.e. after reboot, sleep, etc.)
