Will test it out on my X299 FTW K + 10940
Edit: per core overclocking, even using the same multipliers, is still slightly slower in Cinebench R15 than the other method. I'll test more, but so far it's not worth the BSODs that I'm getting trying to OC even my best 2 cores (1 and 13, the ones that supposedly can do 5.2GHz according to OC Robot).
Edit 2: nothing gets even my best 2 cores stable. Even just 1 bin higher (48) than the rest (47).
Edit 3: FINALLY got cores 1 and 13 to work at 48 (1.175V override) and then 49 at (1.25V override). Not sure if the CMOS clear (after needing to do an earlier one right after the initial upgrade to 1.23 as it wouldn't boot) helped or not, but it's finally actually working.
