    Only recently I've stumbled upon info that MSI laptops (particularly mine) are easy to tweak, thanks to hidden advanced options in bios. For 4 years I thought 2133CL15 was the best I can have on this laptop...

    Though RAM showed itself being a potato - 3200@17-19-39 is not that good, overall it is great.

    So far I was curious if someone managed to overclock HQ/H CPUs? Are they totally locked? Maybe someone found something for the last 5 yrs?

    P.S. Would be great if website had a search function in dedicated topics, not only through entire forum.

    So Haswell CPUs had a bug in the early microcode revision, that allowed setting the multiplier as high as you wanted via Throttlestop. Basically with the combination of throttlestop and a bios mod meant any Haswell CPU was unlocked.
    Refer to:
    http://forum.notebookreview.com/thr...-intel-haswell-cpu-microcode-bug-hack.790177/

    Now Skylake apparently had the same bug, again only on a very old microcode version.

    You could have someone to modify your bios to downgrade the microcode with something like the UBU tool. Worth a try.

    I see. Any tips of micocode ver/date?
    So all those ratio and OC settings in BIOS - that is purposed only for downclocking, or are those just a leftovers from old microcodes?

    Likely for downclocking, even if you use an old microcode you can't overclock the cpu via the bios, it has to be done via throttlestop.

    Throttlestop takes advantage of a bug in the code, I don't know the details but it's not a standard overclock. Refer to the above mentioned thread for more.

    I would personally use the oldest microcode available (some versions of the UBU tool contain a database with many microcode revisions). If the oldest one doesn't work then likely nothing newer will.

    I can upload the best UBU tool that I have, if you intend to try modding the bios yourself. However make sure you have a way to recover from a bad bios via SPI programmer.

    On my first attempt, I bricked my machine .

    Also, no all HQ's are good clockers at all, they are binned silicon and ended being locked CPUs for a reason..
    My 4720HQ is a dog, its not stable at all above stock clocks, 3.8Ghz is only semi stable at +50mV and at that point its running at near 90Watts, can run CB R15 for days, but some games will make it insta crash.

    I see. Well, guess I'll stay with current EC for now, maybe when it fall deeper performance-wise I'll think about bricking it couple of times :D, just to achieve 4GHz allcore eventualy.
    Yup, I know that - CPUs being binned aswell by current leakage, power draw, silicon quality.
    And it's really pretty hard to determine where to go, without voltage or temp sensors available for monitoring. RAM OC is totally blindfest, no temps, no voltages, I'm not even sure if my sticks get their 1.35V, or BIOS voltage setting doesn't work at all.
    CPU is another thing. Though I can ~determine it's capabilities from VID, it's not Vcore anyway. But IF VID corresponds actual Vcore, my 6700HQ requests 1-1.1V for 3.1-3.5GHz, so my guess - it would have been pretty overclockable. At least, 4GHz without a sweat.


    P.S. Is there a thread dedicated to RAM OC? I'm not good at low-binned RAM OCeing - judging from Typhoon I have Micron b-die chips, those seem to be pretty average - right?
    3200@17-19-39 - and that is pretty maxed-out, won't go any further. 3200CL16, anything above 3300, 2666CL14 - that's all out of reach for my sticks.
