3770K Clocks down itself while overclocking_Need Help

Here's the best advice I can give you regarding overclocking your CPU.

First almost every overclocking guide on the net for the Ivy Bridge CPU are total BS!

Too many are written by guys longing to return to the old days of overclocking wanting to tweak everything they possibly can tweak.

In that process, they tweak things they should have just left alone and they would have successfully reached their overclocks.

Just because Ivy brought new voltage tweaks on the scene, doesn't mean you should have messed with them, but most think because they're there they must be tweaked, and in doing so you create your own instability.

We all know what the slang for KISS means Right? (Keep It Simple Stupid)

So why are so many determined to complicate a raised multiplier CPU overclock?

Because the guides lead you in that direction.

Overclocking base knowledge is very important, because if you have that as a foundation under you, you do not need a guide to overclock your CPU.

Lets talk 3770K, I run mine at 5ghz at 1.375v 24/7 rock solid, because I am running the cooling that allows me to do it, and it has not been delidded!

Your H100i should easily allow you to reach a stable 4.5ghz ~ 4.7ghz maybe even possibly 4.8ghz.

BIOS settings have a lot to do with how far you'll get with your overclock, just one BIOS setting set wrong can throw a wrench in your overclocking gears.

You have an ASUS Maximus V Gene Z77, I have an ASUS Sabertooth Z77, meaning we should have very similar BIOSs, so I'm going to share some settings with you and you compare those to how you are set.

Under Advanced Tab select CPU configuration.
Thermal Monitor = enabled
Hyper Threading = disabled until you reach a stable overclock without it enabled, then it normally takes a little more Vcore to run it.
Active Cores = All
Limit CPUID Max = enable
Execute Disable Bit = disable
Intel Virtualization = disable
Hardware Prefetch = enable
Adjacent Line Prefetch = enable

Under CPU Power Management:
CPU Ratio = Set for the multiplier you want to run
Enhanced Intel Speed Step = disable
CPU C1E = disable
CPU C3 = disable
CPU C6 = disable
Package C States = disable


Under the same Advanced Tab select System Agent:
Make sure Memory Remap is enabled.

Before you go any further if you had to change even one of those settings above hit F10 save and exit the BIOS and allow the machine to restart and go back in the BIOS to continue, because some things will automatically change under the AI Tweaker Tab.

Under the AI Tweaker Tab:
AI Overclock Tuner = manual
BCLK/PEG = 100.1
Multicore Enhancement = enabled
Internal PLL Over Voltage = enabled (Even though you are not going to manually change the PLL voltage setting, you do not want to limit the motherboard, if it automatically needs to over volt the PLL to remain stable.)
CPU/DRAM Ratio = set to your need to properly run the memory speed of your modules
Set actual DRAM module speed
EPU Power Saving = disable


Under DRAM timing choose the manual setting option, and manually set your timings.

CPU voltage = manual or fixed
CPU voltage actual = whatever safe voltage you choose to begin testing with
Dram Voltage = manual
DRAM voltage actual = whatever your memory modules require

Below this point leave all the voltages on Auto

CPU Spread Spectrum = disable
BCLK Recovery = Auto

I strongly suggest you start at 4.5ghz a 45x multiplier at about a 1.150v and begin your overclocking journey from there working your way up to a higher overclock, once rock solid at 4.5ghz write your settings down and continue for a higher overclock, but you'll always have the 4.5ghz overclock to fall back to as you progress.

Any Questions?
