Hey everyone, I'm facing a bit of a challenge with overclocking. The VRIN voltage is at 1.8 and the VCore is 1.125. This is my main concern. All others suggest a VCore voltage of 1.2 or higher, but my motherboard only supports 1.2 volts. Anyone have experience with this configuration or any suggestions?
Specs:
Mobo: Gigabyte GA-B85M-DS3H
CPU: Intel i5-4690k
Cooler: Cooler Master Hyper 212 EVO
OS: Windows 10
Target/Current Clock: 4.2 GHz
I know these parts aren't perfect, but I'm trying to work with what I have. The temps are manageable (max 61°C for one core) but I still get BSODs. Thanks!

Unless you possess a modified BIOS that supports multiplier adjustments on the B85, achieving a stable 4690k via BCLK overclock is not feasible. This is because such changes would also affect the clock signals for DMI and PCIe bus, leading to instability and crashes.

If your BIOS permits adjusting the CPU multiplier on the B85, you may be facing stability problems due to insufficient VRM power phases. The Gigabyte B85 DS3H features either a 4-phase or 3-phase design (varies by revision), which is likely to compromise performance. These boards were not intended for overclocking.

A B85 won't be able to properly overclock a 4690k. You can't raise the multiplier. The only adjustment you might make is BCLK, but on Haswell it's linked with DMI and PCIe bus, which will likely become very unstable beyond a 5% boost.

Overclocking a B85 onto a 4690k isn't feasible. The multiplier can't be raised. You might only manage to adjust the BCLK, but on Haswell it's linked with DMI and PCIe bus, which will likely become very unstable beyond a 5% boost. I've already surpassed that limit. Right now my CPU is at 4.2GHz, but it's experiencing crashes and I need to understand the cause.
