Undervolting anomaly..??

[mikekir97]

Hello to the beloved community.. I searched all over the web about cpu undervolting its limits and benefits.. all this for my newly bought Lenovo Legion Y540-15IRH with an i5-9300H 8GB RAM(for now 16GB coming soon) and an RTX 2060.. 1080p 144Hz panel.. Cooling here is very good out the box but i wanted to see how low i could get the voltage before i get "the" freeze or a blue screen.. Now am using intel xtu and have -0.185V offset... completely stable i lowered the voltage very slowly over a week or so by -0.005 and still even now everything is very stable.. under every benchmark or stress test i could find, non raised more than 70 degrees (Celsius) no matter for how long, it just stays there and very quietly so.. boosting works fine at 4.1Ghz all core but, mostly it just hangs at 3.99Ghz on full load.. Is this normal..?? should i lower it more to find the lowest point my cpu can handle..? Also forgot to mention that it recovers from being to sleep just fine.. i saw in on post here that someone had a problem like that.. Should i keep pushing it..?? any danger to my cpu cache as it also undervolts..? (I should mention that i have disabled the intel gpu from the lenovo vantage software, only the RTX 2060 is active)

Thanks for reading..!

How is this an anomaly? Undervolting your PC won't damage it, it's just a sacrifice for performance for temperature.

Your laptop is working beautifully. Be happy. You got a good one. Maybe send some screenshots to all of the OEMs and show them how a properly engineered laptop is supposed to operate. The world is knee deep in poorly engineered, over priced, supposed "gaming" laptops that are junk.

 

Some Lenovo laptops used to disable Intel turbo boost when gaming. Run XTU in the background, play a game and check the graphs when finished to make sure there are no problems.

I think performance is not affected as the actual clock speed is not changed.. boosting is fine at 4.1Ghz all core just didn't managed to capture it right now..;p (This is ltt forums.. clickbaity title required..xD ) (just a joke Linus..:3 xx)

Thank you for your reply..!! I tested that with HWMonitor and it does boost up to 4.1Ghz (all core) in CS:GO never exceeded 65 degrees Celsius .. Performance is amazing on this machines.. Warzone managed to get the cpu to 70 degrees and cpu to 65..

Run R20 before and after undervolting. You'll likely lose score.

hmm.. okay.. i will try.. as it stands i get 2006 score in r20.. with only bitdefender in the background..

The best Cinebench R20 score on HWBot for the 9300H is 2005. I think 2006 points is doing pretty good.

And no, under volting will not cause your scores to decrease.

Oh my.. hahah.. I didn't search for other scores..xD That's great..! Thank you for letting me know..:D
