Hi everyone,
Guessed I finally caved in the pressure from the LTT videos in joining the forums .
I had a bizarre issue today with my CPU, which I managed to fix by disabling the thermal throttling of the CPU in the bios. I was wondering if anyone had thoughts about the issue I was facing and the solution I used.
For a reason that is beyond me, when I booted my PC this morning, my CPU frequency was at 800 mhz. Yes... Pentium III speeds here...
I ran the XTU program from Intel, and it was confirming that the CPU was thermal throttling... even at temps of 28 degrees Celsius. Did a stress test, and the clocks would stay a firm 800mhz and temps at 25 to 28 degrees.
I cleared the CMOS, and reflashed the bios. No dice. Still thermal throttling.
Prior to all this mess, I was running a very stable overclock of 4.9ghz at a voltage of about 1.4volts. Yes, it is a bit high, but my temps were stable at around 85 degrees under max load. I was thinking of eventually delidding the CPU or at least changing the thermal paste to something maybe a bit more performing, but overall, my AIO at quiet settings was still keeping things under control - especially considering the i7 7700 series was notorious for bad temps.
So what gives? Faulty mobo (MSI Z170a M7)? Faulty CPU?
Before throwing the towel and just getting a new mobo and CPU, I decided to disable the thermal throttling directly in the CPU (via the bios).... and voila! Problem solved. Back to regular speeds on CPU, with totally normal temps.
Has anyone ever experienced this? What are you thoughts on what happened and the solution deployed?
