hi everyone
i have recently noticed a drop in performance of my PC and when i checked cpu-z it says my core speed is 1200 MHz. it stays at this speed whether the system is at idle or under full load when running prime95 or intel XTU stress test. the multiplier range is 12 - 39 but it does not change under load. I have tried to disable EIST and turbo boost but that has made no difference, I've played around with the multiplier and vcore in the bios but the multiplier just remains stuck at x12.0 in windows. temperatures are relatively low ( 25 - 29 Celsius) but intel XTU says 100% cpu throttling. I am clueless as to what is going on here
system specifications
intel core i7 4930k
Asus ROG rampage iv black edition
Corsair dominator platinum 32 GB 2400 MHz
Corsair H100i watercooling
Cooler master silent pro M2 1500w
kingston 240 GB ssd now
WD black 1 TB
any help would be appreciated, thanks in advance

Hi ZestyPineappleCE,
I would suggest running the Intel® Processor Diagnostic Tool (http://www.intel.com/support/processors/sb/CS-031726.htm http://www.intel.com/support/processors/sb/CS-031726.htm) just to check the processor overall health.
Please check the BIOS settings and add a picture of the processor Settings so that I can take a look.

Hi, thanks for your reply I got it running at its normal frequancy again. Not sure how this worked but I switched the jumper to LN2 mode, booted windows up and it was running at stock speed once again. Once I changed it back it continued to run at its stock speed and ramp up under load. ☺
