Higher Volt Lower Clock = Instability?, Trouble with i7-6700k

Hi, I just got a 6700k ES(Engineering Sample) like few weeks back and every 1 or 2 day I get a BSOD of WHEA_UNCORRECTABLE_ERROR in Windows 10.
Spec as followed: i7-6700k Engineering Sample (3.4Ghz default @ 1.187V) ASUS Z170m 1x 16GB Kingston Value 3400 DDR4 RAM Zotac GTX1060 CoolerMaster Vanguard 850W
I started off with stock BIOS settings and still it BSOD.
I tried different settings, like bumping up voltage such as running 3.6Ghz/3.8Ghz @ 1.35V which is a higher voltage considering a stock i7-6700k should run at 4Ghz @1.2V. I ran Prime95 for 30 minutes and it's all good but it BSOD on random task like browsing web site/play youtube etc(surprisingly it rarely crash when gaming)
So my question is, can I run at a higher voltage but at a slower clock? Or will that cause stability issue? And if any of you happen to have this ES(2.6Ghz version) which I got from a LYN forumer in Garage Sales, what sort of settings are you guys running on?
Thanks.

Depends on chip, ideally you want to get a good clock with lowest voltage possible.

Thanks. with bolded, i think there may be issue with specific hardware and best if you can run stress test/memory test etc to rule out what specifically is causing the issue. (maybe psu voltage instability? memory sticks? maybe swapping the stocks around? possible to swap hardware such as cpu/mobo/memory etc?) increasing voltage while keeping stock clock MAY help, however it is a workaround method dodging the original issue and you gain nothing out of it as increasing voltage also potentially reduces component lifespan/increasing temperatures while not gaining performance which seems very detrimental and totally against the original intention to increase voltages.

Missed this - yes you can run at higher voltage. Just don't go too high. Up the Vcore by 0.05, go bit by bit until you get it stable.

Getting Started
|
14nm less tolerance on high voltage, long term usage not recommend over 1.3v
