So im trying to see what is causing my CPU to show up as 1199mhz in realbench
Water cooled cpu 30c to 50c
i7-5930k 4.5ghz 1.280v(Auto Voltage)
Cpu cache 45 ratio min and max 1.420v(Auto Voltage)
DDR4 G.skill 2800mhz 1.2v(Auto Voltage)
SSD samsung 840 pro 512gb
Evga gtx SLI 980ti Classy's 1485mhz/4000mhz
Asus Rog Rampage V extreme 2014
stable{no crashing} with current setting with ok scores but not consistent with each test from 13381 to 15338 scores

like right now at idle my cpu is fluctuating from 1199mhz@0.840v to 3500mhz@1.130v in CPuz screen.
Looking for all advice since im new to OCing and would like to get a little more performance

first picture i got cpu to 4.6ghz and 3000mhz memory unstable but my highest score

Your Windows Power management is on Balanced... Do you see in CPU-Z at the Multiplier: 12-36? When under load, it will jump up to 36 - so it will run 36x100=3600MHz...
It is a power saving feature of the Windows... If you change Power Management to High, it will keep your CPU at constant 3.6GHz - but it may produce more heat...
RealBench is reading your CPU when it is in idle, that's why it is reporting lower speed... don't worry about it!

Thanks, that fixed the Mhz drops and voltage.

Here's the new benchmark

I have to say 4.5GHz at 1.29 volts is pretty amazing. You got a really good sample. I had to go to 1.32v to get mine stable at 4.4GHz.

I personally use adaptive voltage to keep the heat down. 🙂

Im currently back to 4.4Ghz getting better performance here is the new bench, Also tested 3dmark 15250 score on Firestrike extreme @1440p 16893 score @4.2ghz
