3:00 for Gigabyte "Level" is the negative curve it applies to PBO Curve Optimizer with 70/80/90 obviously being temp target, Level 5 is -50, Level 4 is -40 so on.

Have been using enhanced 2 with 85C limit along with the tighter memory timings option on MSI with a 7800x3d. No crashes so far, and a much faster system with less lag. MSI claimed that it gave at least a 10% uplift, although its dependant on silicon quality. It seems to undervolt the chip, and change a few other settings.

The level on the Gigabyte boards is the negative offset x10. So a level 3 for example would be a -30 negative offset. You can get better fine tuning doing it manually, but its a good starting point. Most will handle 1 and 2 just fine. A lot will handle 3 not as many will be able to run at 4 and only a few golden samples will be able to still be stable with 5. Basically it moves the curve down by that many steps so you end up with less voltage needed for the same frequency.

Asrock has something like this. You may select temp targets of 65, 75, and 85c in addition each of those targets has a -20, -30, and a -40 offset that you may choose to use with that target. I have tried both the 75c -20 and 85c -20 on my 9800x3d and get a full 5.2 Ghz boost across all cores with 70c -20 running Cinebench R23 with the package watt draw living around 125 -130 watts

Weird. So I have a B650e Elite X AX Ice and I don't have these PBO levels enabled, but i do have PBO set to "Manual" and have specific dialed in values for TDP, EDC, etc so that I don't hit 85c and have Curve Optimizer set for -20 all core undervolt. Got load line calibration set to Normal. I hit about 77.3 degrees in Cinebench and a score of 13,630. But would I benefit more by using these set PBO levels instead of my manually dialed in values?
@Eren-da-Jaeger
@Eren-da-Jaeger 12 күн бұрын
no. If you achieved numbers while remaing under the max temp that you were trying to lock your boost to, then you did well and whatever score you got comes down to rest of system config and particular chip.

​@@OGSuperDirty I worked for an RC company and we could to tell if too much volgate had been connected to a speed controller. As soon you you connected anything above a 3s pack to it would blow a transister to short. it wosuont stop the Speed controller from working at all. And outwardly youd never know. But it was easy to check and if it showed as a short in the test board then no waranty claim. I suspect that AMD are doing somthing but more advanced in the CPU. So youd get a short on one of the pins to ground when you enable PBO. So it would be a very easy check. Supprised no one has tested every pin before and after to see if thats the case.

It`s just the cpu staying cooler and clocking higher because of the increased headroom. No magic. Just some tinkering, it can be unstable though, so tune it right.

@brugj03 that doesn't really explain how it improves performance per watt without any changes in IPC. The only explanation I can imagine is that it's using lower voltage at the risk of issues with silicon lottery losers. Where else could that "headroom" come from?
