    Well, since third gen (Ivy bridge) graphics don't support the official intel solution to overclocking and I can't use PEG mode (Optimus only). I went ahead and had my friend help me flash my EDID in Linux. My laptop now has 85hz available everywhere.

    I used CRU to add the resolutions, then exported the EDID and flashed it in Linux using edid-rw. My friend is lazy and won't make a tutorial sorry.

    basic steps:

    Open CRU in windows, add the resolutions/refresh rates desired (I started with 75, 80, 85, and tested each).

    Export EDID from CRU

    Launch Linux and use the edid-rw tool to flash the new EDID (use the help command to check what the command is to flash).

    Reboot and hope it didn't brick. TO be fair we flashed my EDID like four-five times and it's fine. Now I can run 75, 80, 85hz in games too. So smooth.

    But can't you use CRU to set a custom HZ anyways, or no because of the iGPU? And isn't it available for Linux? Oh well this is a nice guide anyways

    CRU only supports Intel 4th gen(Haswell) and newer. The drivers for 3rd gen(Ivy bridge) and older don't support any mods done by CRU or INF mods. So a flash is required to get around that.

    Also this is nice because the panel is natively at 85hz now

    Yup! no issues in any game selecting the resolution/refresh rate! It is risky though if you do something wrong, you'll have a bricked display lol

    Don't you have PEG available on your M18x? Which GPUs is it running?

    I've been looking at M17xR4s actually recently lol

    I meant what GPU(s) are you running right now? This mod is only useful if you have 1060/1070/1080 installed that requires Optimus.

    Did you give up on the M17x? lol

    Can’t you still overclock the panel if I run a WX 7100?
