Wierd cpu underclocking

Ross_12 · May 23, 2016

For some reason my i7-4790 (non k) is clocking down at high cpu load and I cannot figure out why, so I bought a new cpu cooler. Same results, new thermal paste, nothing, all fans at max, nothing, please help as I am at the point of getting a Mac.

Hopefully these pictures will help

If it is clocking down that means it is probably thermal throttling.

Thermal throttling is when a CPU gets too hot so it down clocks itself in intervals until the temps are stable and below the max temps it can handle.

Hi assassin, thanks for your answer, but I feel that It is not thermals that are limiting, as I had an i3 before this with he stock cooler and that used to get to 85-90 and sometimes 95 and never used to do this.

Could it be something to do with power or my motherboard?

85-95 is very bad and you could seriously damage your processor, it shouldnt be running that hot even with a stock cooler. what are your I7 temps?

And what is your motherboard?

assassin445522 :

My i7 temps are about 65-70 under load but when it under clocks it goes back down to 45-50, the motherboard is MSI-h81m-E34

Also the temperature spikes up to 65 degrees and stays there for a little while and is clocked at 4.44 Ghz, then reaches 70 and stays there for about 2 minutes, still clocked at 4.44ghz then it will clock down to 4.4 Ghz, then after 30 seconds it will reach 3.96 GHz and start the spiking shown in the pictures, and drop to 0.7 Ghz every few seconds.

Hope that helps

Bump? Anyone?

Ross_12 · May 25, 2016

Hi everyone, If anyone is havin the same problem as me, I have found out that the motherboard vrms were overheating so would not give my cpu the required power until it was cooler, so far I have found a tiny heatsink and put thermal paste on the capacitors and vrms which are all within each other, and put the heatsink on that, it has not fixed the problem completely but has made the time that the cpu maxes out from about 2 seconds to about 10

Hope this solves it for everyone
