Been using this for over a month, working as intended.
Tried it on Claymore and Phoenix and no problem

I put mine on a fixed custom curve 1600mhz @ 0.8v Memory. +360 exact / 5865mhz on MSI Afterburner . I found out putting higher value (such as 500) is not helpful but instead, finding a specific value helped tremendously. You should take some time and raise or lower it by increments of 10 as it’s really sensitive to the change. Long time ago but I remember +500 only doing 52-52.5 on my card until I lowered it down.
