You can now get anywhere from 20–30% “free” performance out of Intel Core Ultra on LGA 1851, and the reason this guide matters is simple: the early BIOS situation pulled performance back hard. In this video I show my updated, socket-wide method that works on basically every board and every brand (B860, Z890, ASUS, MSI, Gigabyte, ASRock). Before you do anything, I want you to update your BIOS, then go straight into Advanced Mode and set up XMP/RAM properly—because RAM instability is one of the most common ways people think their undervolt “doesn’t work.” From there I walk you through dynamic undervolting (offset) first, because it’s the most universal. On some boards it’s in the usual voltage menu, but on ASRock B860 it’s under CPU DLVR. I give you starting points like -50 mV (works for most), -30 mV (basically universal), and even -100 mV if you’re lucky and you test properly. I also cover static/fixed voltage tuning (around 1.15V as a sweet spot), explain why B-series ratio limits change what you can do, and then I show you how to unlock performance via power profiles or by manually maxing out PL1/PL2/current limits—assuming your cooling is actually up to the job.
