Undervolting

[Oussama Ilahiane]

Hi everyone , I got a laptop with an i5 4210u and i wanted to undervolt it for better power consumption and temperature , my cpu is really cool in general , i just wanted to try the undervolt feature

I reached an offset of -70.3mV and with a software called Hwinfo , i saw a significant power consumption drop , from 13.42W in average with only the cpu at 100% to 12.4W and i started wondering if this can result in better iGpu performance , so i downloaded prime95 and Futuremark , with 0 offset voltage and both my cpu and gpu at 100% , the gpu clock speed was jumping betwen 450 Mhz and 510 Mhz and after the offset , it became a stable 550 Mhz , i know it's insignificant but still , it's an inexpected improvement

But I still don't know if my system is stable or not ( for the moment it is ) and i don't want to risk a BSOD in the middle of a game so i want to ask you how much time i should run Prime95 and if i should try to undervolt it a little bit more

 

The software i use to undervolt the cpu is ThrottleStop TS Obsidian and also i was about to forget ! , how can I reduce my cpu cache voltage ? i saw it on the forum about undervolting but i don't know how
