Step #3 Optimizing the OC/GIGABYTE OC Profiles
The GIGABYTE Z77 boards allow a user to set an offset
instead of a fixed voltage, so instead of picking 1.4v, I could instead tell the
CPU to drop its voltage in scenarios with less load, and increase during load.
This is done with DVID offsets, which is an amount of voltage you select which
is added to the CPU VID(the CPU’s stock Vcore). However you need to also have
C1E, EIST, and C3/C6 states enabled, as well as Turbo Mode enabled to properly
drop and raise the CPU frequency.
Newer boards such as those from GIGABYTE and ASUS, use digital PWM
technology, will have a special page where users can mess with and optimize PWM
settings. To determine whether or not your motherboard has a digital PWM you
should look in the power menu and look for settings such as those below, one the
staples of digital PWM technology is a user configurable VRM.
Please note that you do not need to set LLC to Extreme, nor the others to extreme for only 4.8GHz, most of these options I change by habit for extreme overclocking with liquid nitrogen. For 99% of Overclocking there is no need to change any setting other than LLC.
However many of you want to know what the other settings do, and I will show be
PWM Phase Control: This
setting determines how to balance temperature with performance to provide either
the best VRM performance or the best temperature for the VRM itself.
Voltage Response: This is a setting
which directly correlates with the transient response of the VRM, turning this
to fast will increase the temperature of the VRM.
Load Line Calibration: This setting can
be increased in intensity which will decrease the standard Vdroop setting for
the voltages, the CPU VCore LLC is the most important, and if you are OCing on
air you should set Turbo and if on LN2 you should set Extreme.
Over Voltage Protection: This
setting determines the upper limit on how much voltage can be supplied over the
Over Current Protection: This setting determines the
upper limit on how much current can be supplied over the standard setting, I set
to extreme always, just because the CPU uses as much current as it needs and no
This setting determines the upper limit on the MOSFET temperature of each phase.
Each phases uses a tiny thermsistor to gauge its temperature, and that
information as well as current are fed into the PWM to balance out the output
across all phases evenly. This setting just allow you to not have VRM OTP shut
down. There are upper limit protections which are not visible nor modifiable by
the end user, and they should ensure a shutdown if the VRM overheats.
PWM Switch Rate: This is the
switching frequency, or more simply put the amount of time each phase can switch,
increase this and you increase the amount of ON time of each phase, thus
increasing overall heat, and increasing the rate at which the current is
supplied to the inductor, however the VRM on this board is already optimized for
auto. Even under LN2 with the UD5H I do not change this setting.

Gigabyte Profile Sharing
For Z77 many manufacturers have brought out all the tricks,
as Ivy/Z77 is the first time in a year that anything exciting for the extreme
LN2 crowd has come out, and manufacturers love the extreme crowd because it
gives them a chance to test out certain aspects of their boards to the max. To
facilitate a much more interesting and easy user experience GIGABYTE finally
recently incorporated named profiles within their UEFI. However they also added
in the ability to save your profile to a USB or SSD/HDD, this means that users
with the same model board (example= Z77X-UD5H Rev 1.0) can swap profiles and
help each other or share their memory settings and so on.
save a profile name for a total of 10 user profiles in the BIOS.
Or you can save a file and set its name to a USB stick and
send it to a friend or keep it safe.
GIGABYTE's Tweak Launcher:
Known as GTL
this program is where it is at for LN2 and even air OCers. It is a simple
executable like RealTemp, in that it has all its drivers in its folder and takes
no installation. You just have to have Intel ME drivers installed just like for
EasyTune6 for BLCK and multiplier change. Make sure to run the program as admin
if you want BCLK change, but this program makes EasyTune6 not needed for LN2 OC.
By the way if you like EasyTune6, it is fully functioning for
For memory timings you need to use GTL.
