Yeah, I saw it the other day and have been doing some small testing for vdroop control.
At 5.1 GHz, 1.35V adaptive, the vdroop options provide this max voltage (using hwmonitor) (in order from high LLC to low)
- Disabled (for extreme OC) = 1.48
- -75% (min vdroop) = 1.424
- -50% (small vdroop) = 1.392
- Default (Intel reference) = 1.352
- +25% (more vdroop) = 1.344 (some errors)
- +50% (large vdroop) = unstable
- +90% (max droop) = unstable
My CPU cooler is a Corsair H115i, a 280mm rad, and my CPU is delidded, so even though I was using the "disabled" vdroop options on previous bios, my CPU was staying below 90c so it felt fine. I'm planning on redoing the above chart at different settings to go across the full range while being stable.
I've changed to using the "-50% (small vdroop)" option now. An hour of testing showed this performance (room temp ~75 F = ~24 C):
All the stress testing above is done using Intel linpack benchmark () using version "w_mklb_p_2018.3.011".
Overall, this is a pleasant update, and my max temps were reduced from the high 80s to the high 70s. I haven't tested to see if there's any extra overclocking potential yet, but will in the future.
