14900K at 7.7 GHz: How I Set 50 Overclocking Records with Intel's Raptor Lake Refresh CPUs and Plenty of Liquid Nitrogen

Is VRM switching frequency still a thing these days? The higher, the less voltage you need. At least that's my experience. Ive done some good OC'ing in the past with a Vapochill and such onto a CPU, GPU, applied mods and even managed to get a crazy 120% OC going from 600Mhz on a 2600Pro all the way up to 1330Mhz on a frying 2.2V.
 
I'm curious when doing asynchronous ratios do you actually try to optimize the clocks on the lower ratios? If so what do you use to validate them?

My current setup is relatively ancient so my clocks aren't really pushed terribly far apart so it was pretty easy. It seems like doing a variable ratio overclock today would be pretty time consuming though I haven't had opportunity to test it myself.
