    Can you do a graph like XTU produces to look at what the CPU is doing in more detail?

    Yeah I can do one later.

    Passed Asus RealBench stress test for 4hrs at 4.8ghz 1.2v, and 2hrs XTU. Stayed at 4.8ghz the whole time according to XTU and HwINFO.

    At the thermal limit though. Might ghetto strap a waterblock to it see how high it can go :)

    Everything is working great now, 4.8ghz stable, GTX1070 +175 GPU offset +775 MEM.

    Only issue I have now is when I reboot the CPU speed varies all over from 1200 to 4800mhz. Throttle stop doesn't even do anything.

    Only way to get it to work is if I do a cold boot by turning it off completely. On next boot it's rock solid staying at 4800mhz with ThrottleStop. This is is manual voltage mode.

    If I do adaptive I don't have this issue (but I have the forced Clevo -100 issue, and idle voltage is crazy)

    @Prema Is this possibly a BIOS issue as well? Would rather just stay on voltage override right now.

    What happens if you flick power plans when you do that? Does it vary speed by load or is it random?

    @PeenX2

    Been following the thread because I have a similar configuration with my EVOC P750DM2-G.

    But I'm also interested in learning more about overclocking configurations in general, and I'd like to understand the overclock settings that relate to one another, at least with @Prema BIOS. Would it be possible for you to summarize the changes you made to your BIOS original settings which result in the system you have now? (BTW, I assume you're still on BIOS V1)

    Also, this might be a good time to thank @Phoenix, for providing the only two Youtube videos that I could find, that provide some good @Prema BIOS overclocking information, (1., 2.).

    @Meaker@Sager Power Plans was one of the first things I tried, but it makes no difference. Load makes no difference, it just bounces around randomly. I'm going to try installing Windows on a seperate SSD and see what happens after a fresh install. Usually on a new build I will overclock on a scratch disk to find where it's stable and then do a fresh install.

    @jas I've overclocked tons of systems, different BIOS'es since the mid 90's. The Prema reminds me more of an older DFI BIOS which I like. Brings back memories. If you know overclocking terminology, and the type of platform, being a Prema BIOS isn't really any different from any other overclocking platform. The best thing to keep in mind with most BIOS, including Prema, usually less is more. Usually not really necessary to make a lot of changes in the BIOS.

    I knew coming in, since it was a laptop we will be thermally limited so don't really expect too much. First thing I did was lock all cores at 45x multi, and was trying to figured out what would hold voltage better, adaptive or override voltage in BIOS. Also I set windows to High Performance plan so I can see minimum voltage to compare easier.

    From Haswell CPU's till now, I find RealBench to be by far the best stress test. So I tend to use that to test stability. I use RealBench to find out how much droop the VCORE has during load as well.

    I found override to be more stable so that's where I initially started on this, so I put in a more standard voltage of 1.2v and 45x multi to see where I could go thermally and ran Realbench for a 5min for a quick check.

    After that, I would just go back in the BIOS and add 1x multi till it isn't stable anymore in RealBench. All CPU's since Haswell I've noticed early on, it takes about 0.025v more to jump about 100mhz with stability.

    For example, on this 7700k it would take 1.15v to make it stable at 4.5Ghz all cores loaded on RealBench for 1hr. 4.6ghz takes 1.175v and 4.7ghz takes 1.2v. After that it starts needing bigger jumps in vcore which for one the Clevo is thermally limited and also not really worth bumping the voltage up much more for a small gain of 100mhz.

    After I found 4.8ghz to be mostly stable at 1.2v, I ran RealBench for 4hrs. Then I would introduce other programs to test.

    Once you're done with this, you can start overclocking cache, and memory, gpu.

    Couple other things to keep in mind when overclocking ANY system. Always make note of where you are in BIOS and write it down. It's easy to fail POST and need to reset CMOS and forget where you were. Also, I always overclock CPU, Cache, MEM, GPU with an OS I know I'm going to format later till I know it's 100% stable. Once I know it's good, I like a fresh OS with no BSOD's...I'm weird like that. But you sometimes get little issues like the one I'm having now with CPU clock bouncing all around for no reason.

    Anyways, hope this helps.

    You are one of the most advance overclockers I have seen.

    I think Mr. @Papusan will become your new best friend:

    New problem, if someone might know what's going on.

    If I unplug my laptop, web browsing becomes very slow and choppy. I have throttlestop set to 4.8ghz, High Performance power mode, GPU even set to Max Perf and it's still choppy on all browsers. Right when I plug it back in, it's fine though.

    Is there a BIOS setting that is causing this?

    Your settings are too high for use on battery.
