Can tomshardware confirm an single core overlclock of 5Ghz on air?
What would the point of that be? Two cores has become the minimum even for basic OS operation, a single core OC is useless, even dual core causes usability issues in some software and makes some games either unplayable or refuse to start.
A far more interesting but equally impractical Ryzen OC result is the 5+ GHz LN2 with all cores and SMT enabled RUNNING GAMES AND BENCHMARKS. Personally, I do not regard overclock records that require crippling the CPU beyond usability as valid - there is no point in overclocking a single core to 6GHz when your single-core CPU gets destroyed in most benchmarks by a stock CPU on an entry-level stock motherboard with stock HSF. In many cases, those OC records can't even run benchmarks.
