[roco smith]

Hello i ve just bought a pc with these specs:

AMD Ryzen 3 3100 3.9GHz cPU
Asus Prime B450M-K Mobo
G.Skill RipjawsV 8GB 3600MHz DDR4 Ram

In my system rams work on 3200 Mhz eventho its normal speed is 3600 Mhz. I cant get it to 3600 otherwise my fans etc seems to work but i get blackscreen
cant even get to Bios. I updated my mobo bios but it didnt solve the problem . Could you help me on this issue plz?

Did you check the motherboard memory QVL, was the memory on the list?
If it wasn't on the list, it may work on it's rated speed but sometimes not.

Which RAM ? RAM vendors have JEDEC compliant sets of RAM settings on the SPD but its the "overclocked" setting is what is normally advertised .... generally called the XMP setting.... On AMD its been called AMP, AXMP and DOCP. I'd look for a DOCP setting in your BIOS ... if that fails... use CPUz's SPD tab to determine specific settings which you can input manually (Advanced Mode) . may have to adjust SOC (1.2 max) and DRAM voltage (1.35 max)

Not your MoBo but procedure should be similar

"After entering the BIOS, the basic mode splash screen will appear. Here users can enable XMP (DOCP, Direct Overclock Profile), adjust fan profiles, and apply some 'EZ Tuning' for automatic overclocks that can be hit or miss. Pressing F7 enters the advanced mode. "

perhaps this will help too

I emailed asus about t5he MB and the new chips Corsair Vengeance 3200mhz (2 x 8GB) and they told me the reason it was still running on 2133mhz as its the normal speed for the MB. If I wanted to up to 3200mhz I had to activate something known as DOCP on AI
