Current specs.
Task manager reads it as 1.19 Ghz. CPU-Z reads it as 1.2 Ghz. The bios reads it the same as well despite cpu-z and bios claiming it should be 4.0. I have run this build for a bit over a year now at that speed no problems. It also will not exceed 33% usage under stress testing.
Looking around I found nothing but power management suggestions. It's been on high but I tried adjusting the settings to see if it might "unstick" itself. No luck.
Lots of mention of thermal throttling, well it's temp reads 35C but I tried throttlestop bdprochet to see if it glitched. No Luck.
Seen speed step mentioned, mine has always been off but I tried switching it back and forth no luck.
Slow switch on motherboard is off but I tried switching it back and forth between boots just in case. No luck.
I did a complete reinstall of windows from usb media and a cmos reset. No luck.
Safe mode also has this issue.
The only thing I found to make a difference was to rename the intelppm.sys file so that it was unusable, which brought the CPU to it's minimum frequency but would not allow it's overclock to work.
The fact that doing so works (somewhat) makes me lean towards a software issue, but the reinstalls and resets make me think hardware. I know that intelppm.sys is for power management so obviously there is a problem occurring somewhere in there. I just need somebody a bit more knowledgeable than me to help me piece it together.
Forgot to mention I also replaced intelppm.sys with a clean new version and that did not work either.
