Hey all, so I watched a few videos on youtube about undervolting and how it can actually increase performance while decreasing heat and battery drain. Well I decided why not give it a go so using Intels XTU software I set to work undervolting my Maingear Element. specs are as follows: I7-9750H, 2070MaxQ, 32GB of 2666 memory, and a 1TB intel 660p NVME drive. I started my undervolting by running a 30 minute stress test in XTU to get my baseline temps and clock speeds. Then I let the laptop cool back down for about an hour so that it was back to completely idle. Leaving it in "Redline Gaming" power profile I fired up R20 and gave it a run I got a score of I believe it was like 2345 I then started my undervolting process dropping it -0.010mv everytime. Eventually I got to -0.200mv undervolt and the system was still rock solid stable. I fired up R20 again as with every other drop I would then run R20 to test system stability and temps.(being heatsoaked at that point im sure my temps where destined to be high) However I did manage to get a score of 2633 a 16% Improvement over the Stock performance. I then opened XTU for the final time and ran stress test for 3 hours to validate my undervolt. It passed and here we are. I am now daily driving a laptop with a -0.200mv undervolt applied to the cpu. However system power drain remains rather high for setting it in battery saver or balanced power profiles and when playing games I don't notice a significant drop in temps. However almost everyone on youtube that watched managed to drop their temps in game or in benchmark by 4-5 degrees!! with only -0.050 to -0.100mv undervolt. 

 

Did I do something wrong when applying my undervolt? Is there something else I need to do in conjunction with the cpu undervolt? like undervolting the GPU? Should I change out the thermal paste for a higher quality?

It seems like you did a great job with the undervolt, just make sure that it's applied properly by looking at CPU voltages. I would suggest changing out the thermal paste, just in general.

Yeah I was thinking about doing that anyway I mean I was thinking about pushing it further maybe towards -0.300mv undervolt because its been about a week now living with a -0.200mv undervolt and the system has been completely rock solid. I just thought I would see bigger gains (or rather reductions) in my thermals and in my battery life although both seem to have been relatively unaffected but I managed a 16% performance increase.

Well, think about it like this. You got a 16% increase in performance for the same batt life / temps, so all in all, you are saving battery.

Undervolt only drops power if the CPU uses less power. On these 6 core (and more) parts' case they are originally power limited most of the time so that they just run faster but not draw less power.

 

In contrast other CPUs may hit their full clock speeds or near that in the first place, so they stop hitting the same level of power draw after the undervolt.

Also my voltages when watching them via hardware monitor while running R20 did reflect the undervolt well my base line i believe was around 1.380-1.425 now when running R20 or XTU's stress test my voltages hover around the 1.188-1.265 range so clearly my undervolt worked great I even manage to hold my boost clocks longer baseline saw my clocks dropping down to 3.5ghz while running XTU'S stress test, while running the same stress test now my clocks are closer to 3.72ghz sustained.

Ahhhh that makes sense.
