After experimenting with undervolting my Strix RX 480 and observing effective temperature reductions, I wondered if similar adjustments could be applied to the CPU.
I've been tweaking the AI Suite TPU configurations and modified the following parameters:
vcore - 0.130
CPU Ratio x41
CPU cache ratio x41
BCLK 102.5
All settings remained stable after a 2-hour prime95 blend test, running five times at a maximum temperature of 57°C using HWinfo (the AI Suite reached a 47-degree limit).
An extended xtu bench test yielded a score of 1196 with a peak CPU temperature of 50°C.
I haven’t experienced any crashes or freezes yet, and I haven’t tried lowering the settings further.
This adjustment simply resets the CPU voltage when the PC is powered on again. I’ve set the BCLK and CPU ratio in the BIOS but am unsure how to configure the vcore. I’d prefer the CPU voltage to decrease during idle periods.
I also enabled XMP and ran RAM at CL15 2400 (which resulted in 2460). XMP supports 2400 or 26.
Any guidance would be greatly appreciated. The simpler the instructions, the better.
Thanks.

Keep it straightforward.
In the bios, choose all settings to default or auto.
Adjust the multiplier for each core to your preferred value—41 works well.
Run a stress test.
Target temperatures should be around 85°C or lower, with a vcore under 1.3.
You may need to increase the RAM voltage slightly if using four sticks.
As of December 4, 2016, about 67% can overclock at a reasonable 1.40v Vcore.
