They don’t run 1:1 with 1% more power adding 1% more performance, it’s a curve. The reason it works is pretty simple too – your chips aren’t evenly efficient. Undervolting is pretty simple, you reduce the amount of power your components are using, so they run cooler. Also, The BIOS is designed to allow the CPU to heat up all the way to 99c and rely on thermal throttling to kick-in, even though your CPU is making less heat the Fans will react by slowing down.īottom line, to get noticeable result you need both the GPU undervolted and a way to force the fans to maintain a higher rpm.What if I told you that you could lower your temperatures, save money on your electric bill, and keep getting the same performance? Let me introduce you to the wonderful world of undervolting. Since the majority of the heat in these systems is created by the GPU, using a GPU intense application to test will cloud the results. The people posting a 10-15c difference are probably testing the machine in a situation where only the CPU is active. I will appreciate it very much if someone can share some insights. 0.930v, and undervolting to 800mV dont make a difference I'm currently running on bios 305, and the stock voltage in the bios menu is approx. How come many users of intel XTU claim that they see a huge drop in core temperature (10c to 15c difference!).but in my case it isn't working at all. is 75c ~ 77c, when I turn on Intel XTU and undervolt to -0.125v.the temp is still around 75c ~ 77c. I'm playing Mass Effect Andromeda on my GL502vmk (7700hq, gtx1060 6g) with TurboBoost disabled, and at stock voltage, the average CPU temp.

I've playing around with Intel XTU undervolt for quite sometime now and it seems that undervolting by -0.1v to -0.130v don't make a difference in temperature at all.
