Gigabyte Z77 Overclocking Guide

Hey guys, just had a quick question about my overclock in regards to bus speed. I've ran prime95 for 12 hours on this clock, IBT on high 10 times, and OCCT for 4 hours and it seems to be stable, however the bus speed throws me off. Is it safe at 100.9mhz? I followed the guide to the letter (as far as I could tell, save for adjusting the memory settings, I just loaded the profile).
Specs:
Gigabyte z77 ud3h
Gskill sniper 1866mhz 1.5 v 9 10 9 28
intel i5 3570k @ 4.2ghz/1.08v

Hey guys,
first of all, thanks Tom for a great guide. This gives me the confidence to finally give overclocking a go.
Just a quick question, which I think wasn't adressed here before: Is all of this the same for a LGA1150 or are there differences to the LGA1150 (which as far as i understand is it's predecessor?)?
I was planing to give this a try on my
ASRock Z87 Pro4
i5 4670K CPU (I was going togive it a go with the standard cooler)
Kingston HyperX Fury DDR3 1600MHZ
MSI N760 TwinFrozr GTX760
Samsung EVO 840 250GB
thanks and best regards

things in the bios will look a bit different but it's pretty much the same procedure
haswell overclocking with the stock cooler isn't a great idea though
you can still play around to find your lowest stock voltage
In your guide, you write "So, into your voltage control and manually change the voltages from auto to what they should be."
Any idea what you mean here? I am not sure what they "should be" from the get go.
My goal is a 4.2-4.4 Overclock with air cooling.

Hey all i know i am late to this guide, i am doing what TTL is telling in the guide. But i am not sure that fixed voltage on a asrock bord, means the same as set the vcore on gigabyte bord.
Right now i am at the point, there i started with fixed cpu voltage at 1.100. and worked down to 1.050 on my 3770K on stock
useing asrock z77 extreme 4 btw.

with fixed voltage the voltage won't be able to scale down, so its like speedstep disabled. you will most likely actually have higher overall power draw with fixed voltage than if it were stock settings.
setting the vcore to fixed voltage will mean that vcore will stay the same at all times.

okay, but its staying at a vcore. its jumping around like crazy

what voltage range? (0.8v- 1.1 etc.) might be llcokay, but its staying at a vcore. its jumping around like crazy

Yeah its somethink like that my LLC is set to level 5. Maybe thats worng?
but am i doing it worng then i am using fixed to find the minimum volt?----------
Yeah its somethink like that my LLC is set to level 5. Maybe thats worng?
Here is some pictures of the test i am doing.
and i just think that the vcore sould be more then that CPU-z is sayning there. its set to fixed 1.040 here LLC level 5.

do you want the voltage to scale (fixed voltage is better for overclocks but more overall electricity usage) ?
it looks like lcc. Voltage decreases when cpu under stress.

YES.. want the voltage to scale
yeah its was 100 %
OCCT LinPack AVX enable and all logical cores enable ------------
YES.. want the voltage to scale
yeah its was 100 %
YEP. its was LLC. Now its like 1.032 - 1.040.
Thanks fore the Help

Thank you thank you!
@ Bryan Waters
Bryan, thank you so much for writing this simple to follow and thoroughly detailed overclocking guide! I've tried other guides where the writer simply assumed every reader was advanced enough that he could skip over minor details- which drove me nuts. Others obviously forgot to proofread and skipped things they said they'd cover.
I have a Gigabyte Z77-Up4th mobo which is great, as the bios is identical to the Ud5H, and my i5-3570k has similar speeds to your chip. I'd settled on a 4.2 Ghz OC over the last 4 years, assuming I just didn't get a "good one", but I'm a luddite when it comes to bios settings and OC'ing. All I did was tinker with the multiplier and voltage, though. I always suspected there were other settings I didn't know about, holding it back. Everyone says 4.2 is the bare minimum.
I'd never touched the Vdroop option in bios, nor did I override the auto setting for the various voltages you mentioned. Didn't turn off Turbo boost either. I simply set the multiplier at 42 and eventually had the voltage at 1.29 (yikes!) for a measly 4.2 OC. Now, I'm running OCCT and testing 4.2- with your other tweaks- at 1.18V... still stable 45 minutes in!
I wanted to get my running as fast as possible to minimize bottlenecking on my upcoming purchase of a 1080 Ti for 1440p, 120Hz.
Anyway, this is an old article and you may never see my post, but I needed to kill time during my stress testing!
Thanks again for this- it's been bookmarked, and I'll come back and report on the final results of my (new) OC. Hoping for 4.5+ on a CM Hyper 212 Plus in a big, Antec 902 V3 case.
