could it also be the voltage? or perhaps my PSU isn't high enough, but then again I have no GPU ATM and my PSU is 650W, so I doubt it's the voltage.

I'm no expert so I don't want to give wrong info. 
 
I'm actually dialing my CPU down to 4.9ghz for added stability.  I've been playing tonight at 5ghz and a couple times I've had GTA5 lock up on me with the GPU temp in the low 40's... so I'm guessing it's the CPU.  Temps were only in the 60's but still... I went down to 4.9ghz and had no more lockups.

what's the best software to monitor the exact ghz?
been using cpu-z but i'm not sure how accurate it is

CPU-Z

I tried OC using the MSI Command Center, tried overclocking to 5Ghz but it would show in CPU-Z 4.2-4.4 ghz which is normal... cpu would crash every couple of minutes (unstable)

Yeah sounds unstable.  I ran for weeks at 4.8 with no issues... 5 is pretty good... passed 1 hour stress tests but then has locked up a couple times playing GTA5.
 
So I'm gonna split the difference and run at 4.9 for a bit and see how that goes.
 
CPU-Z is what I use also.

Generally speaking, overclocking through the OS is not as stable as using the BIOS.

Also Cpuz doesn't report correct voltage or clocks for kaby lake.

It's not even coded into the app.

Use hwinfo of Aida's sensor monitoring.

is there anywhere I can get a 1080ti hybrid kit yet?  it's always 'auto notify' on this site and I put in for one on B&W also.  
 
maybe it's a sign I just need to man up and go full custom loops

There's a high demand for it. I got lucky and got one... just gotta be there when they go on sale because they have been selling out in 5 minutes.

ordered the delid + relid kit. hopefully it will be worth it.

It definitely was worth it for me. Watch the video, and take your time on removing the glue. On my CPU, the glue was so dried, what I end up doing was taking a cotton ball and lightly dabbed it in rubbing alcohol and started rubbing on the glue to break it down, afterward I used the corner of a credit card to scrape it off. As for the relid portion, I actually put a dab of glue on each corner of the IHS before placing it back down on the CPU. Good luck.

Good morning OP,
I'm curious, did you manually set the "CPU Core Voltage" when overclocked to 5ghz or did you leave it at AUTO? If you left it at AUTO do you remember how high it got when benchmarking?

 
I really don't recall the setting.  I've seen so many different voltage numbers this past week and dialed it down from 5ghz because it locked up a couple times playing GTA5 despite passing stability tests.  I dialed it down to 4.8 and 4.9ghz and haven't had any lock ups. 
 
It was definitely 1.3XX but can't recall the exact numbers.  I'm probably gonna tweak it a bit this evening and will let you know.  I'm trying to get the hang of manual OCing... been reading some guides on what to do and what not to do... LOL

Yeah that's all I did differently from the video on Rockit 88.... instead of putting the IHS on and then dabbing the side of the IHS 4 corners with glue... I put a dab of glue on the underside of the 4 corners and got a good bond after it set 2 hours.

 
I just ordered a kit and a tube CL LM Ultra, what the heck.  I'm not only curious to see what total drop I get but if I can get the core differential down. 
 

OK, I promised this will be my last post, but I wanted to give some info on what I do when playing around with overclocking.
 
First, you are going to get system instability, crashed, BSOD, and all that good stuff when trying to reach your "magic" number. One thing I have always done, and again this is a matter of personal opinion and preference, is to have a backup of your OS. On any new system I build, I would install Window, do all the windows update, and than use a wonderful program call "Drive Snapshot" to make a complete image of my OS drive. I called this may Clean Image. Once I install all the drivers, necessary software (excluding games, those should be on a separate drive), and any custom tweaks; I kick off a differential backup using the same software. For me, my total clean and differential backup size is only 20 GB. The great thing is you can make an image while Window is up. As for restore, you can initiate a restore from within Window if your OS is not too corrupted or boot off any bootable CD-ROM/USB key. I have my backups on my bootable WinPE USB key and it takes me about 8 minutes to do a restore. I really like this program since it saves me so much time from having to re-install Window, and any image you have can be loaded up as a drive in windows to view, and finally this program is only a 300KB executable.

quick question OP, as I wait for the 1080ti hybrid kit to come back in stock, what tools will I need to do the install?  I want to go ahead and make sure I have everything beforehand. 

A precision tool kit (small phillips screwdriver) and a 4mm socket or nut driver for the backplate removal/reinstall.
 
I have https://www.amazon.com/gp/product/B008BF1XGG/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 and https://www.amazon.com/gp/product/B009MKGRQA/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 .
 
I already had the 53pc set from when I built the PC... I ordered the Tekton precision kit afterwards for this hybrid install because it has a 4mm nut driver.
 
Everything you need for the hybrid install would be in the Tekton kit.

thank you very much for the great reply and links!!! :)

Thank OP, I ordered the Tekton. I am hoping that EVGA will send my step up 1080 TI FE this week since they received my 1080 Hybrid last Friday. I was lucky enough to order the Hybrid KIT from EVGA on the first day that it went up. 

No prob guys... good luck with it.  Yeah I was lucky as well... got one about 30 seconds after they went live... which was about 4 mins and 30 seconds before they sold out.
 
Thanks for the OC backup info too.

Why is it increasing to 1.32?  Am I missing a setting in the BIOS?
 

OP, google "Why LLC is your friend when overclocking", it will explain better than I can why your voltage increase. Short story, your voltage was increased to keep your overclocking stable. In my case, I had my voltage set at 1.325 I think (will check later). I could not successfully test IBT at very high setting when I had LOAD LINE CALIBRATION set to Mode 2. I had to bump up to one for it to complete. Right now I'm running Maximum and I had to set it to Auto.

the only thing raising temps past 85 is the AVX stress tests. Didn't someone say they were unrealistic and you wouldn't encounter AVX in 99.9% of real world situations? 

As for AVX, I would failed running Prime95 version 28.10 when overclocked, but if you go back to a previous version, 26.6 I think, it should run more stable. I did not have problem with that version.
 
Unlike you, I am unlucky in that I have to set my "CPU Core Voltage" at  1.325 for it to be stable while running very high in IBT. I'm sure I can tweak and lower my Core Voltage down a bit further, but I'm comfortable with 1.325 and LLC Mode 5 for daily driver. The other thing is my TEMP when running ITB is pretty cool so I'm not too concern with running 1.325 as my daily.
 

• ITB Standard Temp: Average is in the 60s degree C, with highest spike being 82 degree
• ITB Very High Temp: Average is in the 70s degree C, with highest spike being 82 degree
• IBT Maximum Temp: Average is in the 70s degree C, with highest spike being 82 degree (On Maximum, I was only able to complete 8 passes. I ran it 3 times and every time it would give me an error at the 9th pass. Since my temp is normal and VCore is still in a good range, the only thing I think is happening is I'm running out of memory. I only have 16GB on this system, and since I sent my GPU in for step-up, I'm using the nasty Intel Integrated and it's taking memory from my pool. I might test it again once I get my 1080 TI FE in this Friday.)

For IBT screenshots, go here; 

1. Standard =  prnt.sc/exw1j8
2. Very High = prnt.sc/exw1vd
3. Maximum = prnt.sc/exvu8y

Yeah that makes sense about the integrated.  I ran with it for like a week waiting on my Ti to arrive.
 
So you're saying I'm better off with the 1.27v that LLCs up to 1.32?  
 
I'd love to get a stable 5ghz and I really believe I can being that I'm already at 4.9...  I guess what I'm wondering is... is running an offset for AVX a bad thing?  I've googled it and found a question where someone asked if AVX was in mainstream use and saw a reply "There might be small custom compiled things for super high performance research, but no not typically. I recall reading somewhere that most programs are only compiled to use SSE2/3 even now."
 
I'm just not seeing an issue with using an offset if the AVX is the only thing that pushes the heat on my CPU... and if AVX isn't something I'm going to run into outside of these stress tests should I care about dropping 300mhz to run them without heating up?
 
The guy also mentioned Handbrake as using AVX but like I said, it's nothing like the stress tests in my experience.  I've peaked at 79 with no offset.
 
Thanks for the links... those pics were too small to view.

92c is too hot to run most hardware - IMHO - under water, something seems wrong.

It was in the 90's the other day when the voltage was higher.  Now it's much lower and I peaked at 88C... and it's only seeing these temps running the stress tests that include AVX.
 
Normal usage of the PC has been in the 60's and 70's.
 
I would think if something was wrong with my cooling it would heat up into the to 90+ on everything, not just AVX stress tests.  Like I just said setting up the voltage manually has lowered the temps anyway with a peak of 88C last night on the AVX stress testing... down from the 94+ it hit the other day running the exact same tests.
 
Hell, even in the BIOS under offset it says something like "adding an offset will help lower the thermals when running the AVX instruction set."
 
That's exactly why my thermals are going up... LOL
