Please help! i5 7600k Unstable after GPU Upgrade

[brsigman85]

Hey everyone! So I'm running into an issue that is beyond my expertise and can't seem to find an answer online. I've been running my i5 7600k for quite some time now with a stable 5ghz 1.350v overclock with no issues until recently. I did numerous stress tests and hours of gaming with no problems whatsoever. Yesterday I went out and bought a Evga Gtx 1080 upgrading from my old Gtx 1050ti and suddenly I'm getting a BSOD shortly after starting a gaming session. Am i correct in assuming that the added power consumption of the 1080 made my CPU overclock unstable? I backed the overclock down to 4.8ghz @ 1.300v and seem to have no issues. I was hoping that i could sustain that 5ghz overclock but really don't want to push past the 1.350v i was running it at. I can totally live with the 4.8ghz overclock if having a 1080 means i need to push more voltage to sustain the 5ghz overclock. Just trying to understand how all this works and if my thoughts are correct on whats going on. Here's a quick snapshot of my system specs. (i know my PSU isn't the greatest)

i5 7600k OC'd to 5.0ghz @ 3.50v
MSI Gaming M5 Z270 Mobo
EVGA 1080 Stock speeds
16gb Corsair vengeance 2400mghz (stock speeds and timings)
Corsair H100i AOI
Corsair CX750M PSU
Windows 10 Pro

Thank you all for any insight on this hiccup! Great community here!

Did you update the graphics driver after installing the new GPU?

If not download and install the latest grapgics driver for the new card at http://www.geforce.com/drivers . Use custom install with the clean install option.

The 750 watt power supply should be adequate for the new GPU.

More than likely you are on the borderline of stability at 5.0 GHz. You may need to adjust the core voltage to reach better stability.

Apparently the screenshot link didn't work.

Yeah i downloaded the latest drivers through Geforce experience, I'm assuming It's more than likely what you mentioned with my overclock being borderline stable and the 1080 pushed it over the edge. Going from a 1050ti to a 1080 is a pretty big jump i guess ill just stick to 4.8ghz as i don't really wanna push this cpu with over 1.350v. Looks like i lost the cpu lottery i see people getting 5ghz with quite a bit less than 1.35 on here : / Oh well, I'm loving this 1080 upgrade!!!

Take a look at the part on core voltage .
