Yes it's just great handy tool without going thru Bios editing/flashing/Pathching etc, Lok like AMD paid attention to the Miners and their needs (also when they added GPU task swithcer for Compute/gaming).
I head that for Vega there are even more options for tuning and power mods, also Auto Under-volt feature.
P.S - Can some Devs figure out how they are applying custom timings on the fly so they can make nice utility that applies our Custom Timings? I remember old days of Gefore 6X00 (2005~ era) that there was a small utility that let u customize the timing on the fly so later you could Flash the best timing that you found.
This would be a game changer for multalgo miners, ETH and XMR mining. Just change straps on the fly
You know what would be a game changer?
If AMD stopped forcing you to use effing Wattman to do this.
Haven't been able to test much unfortunately as the above piece of fantastic software just keeps crashing. But from what I was able to test, it didn't give much extra hash on XMR. Won't be testing EThash or anything else because I'm reverting to 18.6.1.
