A320M HDV R4.0 and 5600x

   You will have to take a good look through your BIOS, not just the OC tweaker 
section. I don't have your board so I can't check for you. The UEFI isn't the 
same from one board to the next so what I have on my boards won't match your 
setup. Just go through page by page, item by item. A lot of settings are hidden
under sub sections. This is done to avoid inexperienced users accidentally 
setting sensitive settings to harmful values. "AMD XXX" is likely what the
subsections will be titled.

	Could you possibly share a screenshot of where I change the voltage as I don't see anything under 'OC Tweaker' that references that specifically.

	Limit the cpu boost clock speed to 4.5 ghz and reduce voltage to 1.2 its under oc tweaker screen.

	Also check your cpu speed and voltage

	What fan do you have on the CPU and are you using decent thermal paste on it?

	I looked in the BIOS (7.10) but I don't see a setting for altering the CPU voltage. Is there a different way to do it that I'm not seeing?

	The PSU is a Corsair RM850x

	Thanks for the great reply! Would you also suggest keeping CPB off as well? I keep seeing posts saying to turn off PBO but have yet to find that option in the 7.10 BIOS. Do you know if there is onboard sensors for the VRMs that could be monitored with a hardware monitoring app?

	What are you using for a PSU?

	I suspect the 5600x is pushing the limits of that poor A320m board, it's VRMs are likely getting pretty hot and the extra power needed to support 2 higher capacity RAM modules is pushing it a bit too far. I would try installing both modules then manually setting the voltage to 1.2v and seeing how high you can push the frequency manually, even 2133 in dual channel will be faster than 2933 in single channel. I suspect you should be able to manage 2666.See if that still causes crashing. If so, try positioning a fan to blow onto the board around the VRM area and see if that helps. I had a similar issue with an FM2+ setup some time back, I ended up buying some self adhesive heatsinks (very small ones) and sticking them to the VRMs. That helped tremendously. On some boards though this may not be possible, the components can often be too cramped. The A320 chipset was not really designed for current gen mid range CPUs, they pull a little more current than the severely limited VRM on most boards that use it can support. You can also try manually lowering the CPU voltage and underclocking a little. You will get better performance slightly underclocked and undervolted (-0.05v to -0.2v) than if you are hitting thermal limits and throttling anyway. It's likely all thermally related.
