Excessive vdroop on Aorus AX370 Gaming 5

[DDebbil]

I got an Aorus AX370 Gaming 5 to replace the MSI X370 Gaming Plus that refused to run any RAM setting but 'auto' (another thread about that somewhere on here), however this one has a different and almost equally frustrating issue: Whereas the Gaming Plus was excellent at overclocking my R7 1700 despite its (doubled) 4-phase VRM, keeping the voltages rock solid pretty much regardless of load, this Gigabyte cannot keep them anywhere close. For 3.9Ghz, I have it set to 1.4V vcore, which yields an SVI reading of about 1.385 without load, but under Prime95, this is dropping to around 1.32V in the most power hungry bits - which then causes the machine to lock up. Even with LLC set to 'high' it is still dropping to 1.337V on some parts of Prime95 and locking up (based on the Gaming Plus, this CPU needs about 1.34-1.35V SVI to hit 3.9GHz stably). I am running the latest BIOS. Any ideas what to do about this?

Steve does a great job explaining how unreliable it is to cross-compare exact voltages from different motherboards, and especially from different manufacturers. Here's a link to their detailed article which includes a video as well.

have you tried different LLC settings? or even just settting the LLC to auto?

Auto LLC is what produces the 1.32V. Medium was between auto and high for vdroop.

Not familiar with that boards settings, but I have had similar issues with my Crosshair VI Hero and 1700x. Setting some other parameters like Power Phase Control and such have helped my vdroop even out. On this board I need LLC set to level 2/3, Current Capability to 140%, VRM Switching Freq to Manual, Voltage Feq to 200/300, Power Phase Control to  Power Phase Response and Adjustment to Regular, Power Thermal Control to 120%. These settings got my 3.9ghz OC to 1.4v and vdroop to around 1.35/1.38 but stays stable through all stress tests. I've turned it down to 3.8ghz at 1.35v but same settings on everything and vdroop is very minimal. Just for a 24/7 oc I prefer the less voltage. Maybe something here will help.
