runix18 Posted March 13, 2015 Share Posted March 13, 2015 I was wondering how to make a stable overclocking configuration for a 3920xm to maintain the same boost speed of 3.8 gb when working on all 4 cores, not only on one core. (one core 3.8 / 4 cores 3.6) Quote Link to comment Share on other sites More sharing options...
Khenglish Posted March 13, 2015 Share Posted March 13, 2015 Which laptop? You should be able to change it in Intel XTU. With an unlocked BIOS then BIOS as well. Quote Link to comment Share on other sites More sharing options...

Khenglish Posted March 15, 2015 Share Posted March 15, 2015 3.8ghz is low and requires practically no effort. You can just set the turbo multipliers in BIOS, raise the power limits a little, and it will be 3.8. Quote Link to comment Share on other sites More sharing options...

hius_adaw Posted September 30, 2018 Share Posted September 30, 2018 (edited) Hi everyone! Trying to overclock 3940XM in m17x r4, put in BIOS all cores 4.2 and +5 VID, on partial load all cores goes on 4.2 with no problem, but when I run XTU test or some other heavy tests freq. goes down to 3.5-3.6. I've tried to increase VID +10 and +15 -- CPU maintain arrund 4.0GHz for short, after drops to 3.5-3.6. With VID +20 and +25 -- it drops immediately to 3.5 and I noticed that actual VID all the time jumping 1.01-1.15V under load, but on idle it goes to 1.31. Ok, on VID +20 and more in looks like temperature going to high and may be it is throttling. I've tried with all cores on 3.9GHz with same result... And after with all cores 3.7GHz...and also under load drops to 3.5GHz. Am I doing something wrong?

hius_adaw Posted September 30, 2018 Share Posted September 30, 2018 I belive for that I need an unlocked BIOS? By the way, I've tried to rise up power and current limits by XTU, and made even worth, freq. drops down to 2.9-3.0... Can it be temperature throttling? As in XTU I can see on max VID settings, it throttling arround 100 degrees. Is it downclocking also on arround 90 degrees? As it looks like I can trace some corellation of freq.drop and reaching 90 degrees on any core... I'm still working on cooling improovement, so if I need to keep CPU below 90, I will do so soon.
