    352.86 notebook driver does not block overclocking. It is quite limited compared to the desktop version (limited over-voltage range for example) but it does not outright block overclocking.

    If I remember correctly, it does block core clock overclocking. Memory clock overclcoking is doable, but core clock, which is the more important of the two, is locked.

    That's not the driver. It's the GPU firmware.

    Edited to add: I've spent a bunch of time over the last three days with notebook driver versions 345.20, 347.88 and 352.86 for my 980M, and with stock firmware (core clock locked), Prema's stock firmware (core clock unlocked) and Prema's OC firmware (everything unlocked) trying to reproduce the performance hit in the thread title. No luck with that, but I can assure you that the driver itself does not block overclocking.

    Edited again to add: For reference to where I started this delve into insanity:

    The issue presents itself with an Express Install over an older driver. After I wiped all traces from my PC and clean installed the 352.86, the score was only 500~ points less than 347.88.

    Happened twice with me while experimenting. Maybe it's hit and miss.

    Old files or libraries does appear to be part of the problem but I don't think that's the whole story. I think @Ethrem is probably right that there's something in the firmware. Something twitchy in the firmware that interacts with something twitchy in the drivers that results in problems under OC conditions.

    The root cause of it is a new hybrid GPU virus named NVIDUMUS SUCTAMUS MAXIMUS.

    New drivers seem to work just fine on my G751JY but i don't really bother with overclocking and benchmarking. Was hoping they would turn on mobile G-Sync when combined with the new bios for my notebook model but nothing. :( Still hoping it will show up soon though.

    I am able to overclock both memory and core with these drivers.

    Yeah, your GPU is probably from the same production run as mine so it shipped with a locked GPU clock.
