Anyone try this on a Gigabyte board? Mine didn't work, it freaked out but went in some sort of protection mode. ST only hit 4ghz, multicore was 3.5ghz.

I'm sitting on a X570 Gigabyte Xtreme. F12a BIOS.

Be sure to use a Agesa 1.0.0.4B bios. I don't know how this works in earlier versions. You might need to try different EDC and scalar values.
Some chips just maybe aren't stable with the extra boost.

1x scalar gives less voltage where 10X gives most voltage for multi-core load.

I have a Gigabyte board. To get around the restrictions you need to disable global c-states.

It isn't entirely a necessity but it makes it easier to manage and quicker to set.

If you want C-states & boost + single-thread you need to play around quite a bit to find something that works for you sample cpu. Will require work. [I'm doing it]

Here is a ~balanced setting~ for my 3800X sample for Cinebench R20.

EDC 10
scalar 10x
LLC LOW
cpu voltage offset -0.03125V

Single thread is still throttling but it's not horrible like EDC set to 1.
EDC 11 could be better for single thread but I've not managed to get as good multi with my sample yet.

Multi-thread scores are about equal to manual 4.400Ghz OC.

x570 Aorus Pro Wifi. 3900x

EDC 10
scalar 10x
LLC auto
Vcore: Normal/Auto

I am definitely getting not only amazing boost on all of my cores but the benchmarks to back them up. My findings are that if I use negative vcore offset up to about -0.04 then single core boost scores increase even a bit more, but multi-core suffers. When I apply positive offset up to 0.05 then multi-core keeps increasing but single core suffers a bit.

Just for fun here is a CPU-Z single thread only bench mark with all of the same settings except a -0.04375 offset. Over 560!

@MikeS3000

I could recommend you use LLC and negative offset.

Seems multi-core wants more voltage when single core doesn't. It will increase the overall voltage minimums but not reach up and beyond the 1.500V limit.

You will have too see which LLC setting is best at each voltage offset.
