Ryzen Master Installed which did work with the 7950X3D, it took over 2 hours to do a per core OC optimisation.. I left the default max range as -30 and after 2 hours, it had magically worked out that every single core should be -30! I will never get those 2 hours back, Y-Cruncher immediately identified 3 cores failing.
So I will just follow LtMatts advice and do it manually.. I might do a quick 'n' dirty scan using a cut down set of Y-Cruncher or maybe give CoreCycler a go as I can cut that down easily in time to whatever is most efficient and then do the longer Y-Cruncher runs.
As per the other Thread, my SP is 110, Harshell123 is 111, LtMatts is 111 (was 112 initially) anyone else want to share to see what kind of spread we have, all looking quite tight and reasonable.
