Clocks on this i5 are just ridiculous, it's a MHz monster - 5.4 R15 1.296V, 5.5 R15 1.376V on AIO 21C ambient. On EVGA Dark it runs 5.5 R15 1.385V AIO 25C ambient.

Gaming with it possible at 5.5/5.1/4133C17 1.392V AIO slow fan without bluescreens and errors, if you're into that.

No cold results as I have no LN2 access. Didn't write down VID, imho those values are useless with these chips as every board spits out a different value.

It is quite consistent if using the same board. For example I was able to predict within 50 MHz what max. my 7640X would hit on LN2 after comparing its VID with my 7740X.
