Z690/Z790 & DLVR BIOS option
Recent Z690 Hero BIOS with a 13900K, under CPU power management there’s an option for “CPU DLVR Bypass Mode Enable”.

I would like to know if this option is active and what it actually does, as I cannot find any reference that Raptor Lake actually implements Intel’s new DLVR technology, and that it was only going to be on forthcoming mobile Raptor Lake and then Meteor Lake for desktop. Thanks!*

I've just had a look in the BIOS manual and it's not very helpful. Just says that the options are auto, enabled, disabled. So when it says bypass, I assume that enabled will set bypass to ON and power saving voltage regulation to OFF. I might be wrong, sometimes the wording just doesn't help much. Perhaps they give the option to disable it if performance is reduced, otherwise power saving would be a good thing. I imagine the clever idea is to to save power without reducing performance much, otherwise it wouldn't be doing much that's new. Maybe it does that by adjusting voltage very rapidly and dynamically according to individual core speeds.
This article mentions DLVR for Raptor Lake, so maybe it does apply across all models?

Ah, maybe not according to this article...

If I had a 13th Gen, I think I'd be tempted to experiment and see what results can be obtained. If it does work, you should be able to see the claimed power savings of ~20% (under some reasonable workload I assume) in HWInfo quite easily. Next time I go into the BIOS, I'll see if my 690 Hero offers that DLVR option, unless it needs a 13th Gen CPU plugged in to show up. Obviously it won't work for me anyway as I have 12th Gen, but thanks for the heads up.Last edited by JohnAb; 11-13-2022 at 01:07 AM.
