Just created account to post my thanks to Swag, Totally Dubbed and others for making such an awesome guide.
This was my first time successfully overclocking my Ivy Bridge CPU.
I ended up changing some settings that where in the guide but that part of the overclock journey.
MB: P8Z77-V LE PLUS
CPU: Core i5 3750k
Cooler: Hyper 212 EVO
RAM: Corsair 16GB DDR3 1600MHz
PSU: Corsair CX600M PSU
No GPU at the moment - thinking of buying RX 580, doing research atm.
Following the guide I managed to get Prime85 8h stable OC of my i5 3750k @4.5GHz on 1.25Volts. Great!
I did the offset math and switched to offset mode. But my system didn't like it and started BSOD like a madman. I didn't understand what was going on.
I checked my offset math:
Formula: (MANUAL vcore) MINUS (VID on 100% load) = offset value
My manual vcore was 1.25Volts
VID was fluctuating between 1.2159V and 1.2209V. 1.2209V was most frequent.
So 1.25 - 1.2209 = 0,0291 that makes it 0.030 for offset right?
Or 1.25 - 1.2159 = 0,0341 that is 0,035 for offset volts
With 0.030V I got BSOD before I could reach desktop and 0.035V I only had time to run Bluescreen viewer before BSODed again. Info from bug check files revealed not enough volts so I started adding notch by notch. About 0.045 offset mark I could run Cinebench. CPU-Z showed ~1.2V peak while running Cinebench. That meat that my CPU was craving for more power. As I up volts notch by notch BSOD went away and my 3750k was 6h stable with Prime95 at 0.080V offset. That's a lot right? However WHEA errors still persisted and offset value was uncomfortably high already.
Turning point was when I discovered running AIDA64 or Prime95 for about 10min and then ran Cinebench my CPU got massive drop on volts - that's Vdroop? When my CPU drop below 1,24V that's when Windows registered WHEA error. To counter balance that I up the LLC to extreme setting and then could lower my offset volts to 0.60V. I ran Prime95, AIDA64, Cinebench, IntelBurn Test all came out clean and my system is fast with no BSOD or WHEA errors. With extreme LLC and 0.060 offset my peak volts are somewhere 1.264 which are considered safe.
I had lots of help reading this thread and I hope my journey will help someone else. (If someone else is late for the Ivy OC party)
I really couldn't have done it without this guide.
So thank you again!
