Overclocking for the first time, running into problems :(

Hi everyone,

I just finished building the following box the other day:

- Intel i7-6900k (3.2GHz trying to OC to 4GHz but would like to go to 4.2GHz)
- Asus Rampage 10 Edition 10 (Lastest BIOS flash)
- Corsair DOMINATOR Platinum Series 64 GB DDR4 3200 C16
- Corsair Hydro Series H115i
- Corsair HXi Series, HX1000i
- Samsung 950 Pro (512GB - OS + Apps)
- Samsung 850 Pro X2 (1TB - Raid 1 - Work Files)
- Nvidia Titan X-Pascal

I ran the system at it's default settings and everything seemed fine, I decided to do some research on overclocking using recent videos on youtube to tweak my system. Now what's odd is when I changed the CPU core speed to 4GHz and saved my settings in the BIOS is still showed as 3.2GHz (right hand side of the attached BIOS image) and using CPU-Z (in attached image in the BLUE box) it shows little under 3.2GHz.

When I log into windows everything seems fine, no system lag. A few minuets later the system lags and I get the following from windows: http://new.tinygrab.com/5ff8c90b9c29d14507095e89f9f1b2222ce78cc240.png

** UPDATE: I changed the core speed to 4.2GHz and took a screenshot of HWiNFO64 + CPU-z: http://new.tinygrab.com/5ff8c90b9ce503bc3e6b76ce4098f002aff557bc7a.png system still has windows lag issue when idel

What am I doing wrong?

Thank you for any help/ guidance to this overclock noob.
 
HWiNFO shows your speeds correctly. If you think your overlock isn't being applied, run CPU benchmarks at stock, then run them again when overclocking.
 
Yes it does show the correct speed in HWiNFO, for me I think the confusion comes from seeing in CPU-Z under "Specification" it reads " Intel Core i7-6900k @ 3.20GHz" I would of assumed it would say 4.20GHz. So if my BIOS specs are ok why would windows lag after a few minuets being inside the OS? By Lag I mean it also feels like I have something taxing my system where if I try to move a window around it jumps all over the screen vs a nice smooth movement. What could it be?
 
Set your Windows power profile to High Performance:
1. Start->Settings->System->Power&Sleep->Additional Power Settings and choose High Performance. You may need to click on "Show additional plans" to see it.
2. After choosing High Performance, click on Change Plan Settings.
3. Click on Change Advanced Power Settings, scroll down to Processor Power Management, under that change Minimum Processor State to 1%. Maximum Processor State should already be at 100%. System Cooling Policy should already be Active.
I also go to Hard Disk in the same list and set "Turn Hard Disk off after" to "Never" (I use an SSD and don't care to turn it off, ever).
 
Thank you Ocellaris and Arak for your replies and sorry for the delay (family and work) in my findings. So before I reseted everything in the BIOS back to it’s default settings I wanted to run MemTest86. So before running the test I checked the info on my memory and it seemed odd that #2 wasn’t matching (TinyGrab - Simple. Screenshot. Sharing.) with the rest of the memory. I then ran the test and on TEST 02 it froze my PC at 16% (TinyGrab - Simple. Screenshot. Sharing.) .


So after a CMOS reset I ran MemTest86 and checked my memory info again (TinyGrab - Simple. Screenshot. Sharing.) as you can see it has odd symbols in #4 (what in the world could that be?) ran the test, same results froze at 16%.


Rebooted and wanted to check one last time on the memory info (TinyGrab - Simple. Screenshot. Sharing.) before running this last test, same 16% froze.When I googled the “16% freezing error with memetest86” others have come across this but never on test 2. So I have to assume if I remove all the memory but one and test each one and they do pass it will have to be the Mobo or CPU?


Thank you all for your help!
 
Possible bad stick of RAM in the #4 slot, or an issue being caused by timings being applied to the RAM.
 
Well I've tried all four memory sticks in DIMM slot A1 and they all lock the system at 16%. I thought maybe DIMM slot A1 might be bad so I tried DIMM slot B1 and still the same issue, locks at 16%. What does this mean? Are all four of the memory sticks bad, is my Mobo bad (if so what other tests can I do to see if it's the mobo) or could it be a CPU thing? I'm lost :-/
