oh overclocking the common excuse for so many Tech enthusiasts to spend just a
lot more on their rig this time however I'll be talking about overclocking
something specific a GTX 1080 spoiler
alot alute spoiler alert it overclocks
quite well but there's a wild card here NVIDIA introduced GPU boost 3.0 and it's
a whole new Beast
cooler Master's master case maker 5 features the free form modular system
for nearly unlimited customization learn more in the link in the video
description to explain GPU boost 3 we need to give some information about GPU
boost 2 your graphics card would dynamically change its frequency across
a linear frequency offset curve this is the curve that you would increase across
the board due to it being linear whenever you applied an overclock of say
50 or 100 or ever it was on that little
slider that you had before and then based on the load that's on your card
your frequency would fluctuate along that curve this is generally quite a
good system but it sometimes falls short because it doesn't crank your clock
speeds up to its potential maximum for
every single possible voltage level and these voltage levels will dynamically
change based on things like temperature power and a whole bunch of other stuff
so odds are you're losing performance
somewhere so G GPU boost 3 alongside
other more General improvements over GPU boost 2 allows us to either overclock
the old way with linear offset curves or break away from that linear offset curve
and tune things per voltage Point what
okay so that's kind of rather confusing sorry about that let's actually do some
stuff and hopefully it will make more sense the feature that helps you do
these things is called OC Scanner within the EVGA Precision app which is the only
one that supports it so far although I'm sure it will become ubiquitous soon
within the scanner there are three different modes basic mode applies a set
frequency offset to all voltage points linear mode allows users to linearly
increase the clock offset after choosing a start and end point and then it gets
interesting with manual mode which first off it's fairly self-explanatory you
manually input values for frequency at each voltage step but it also enables
the Run button which is where the fun begins this will run an automatic test
that will determine and apply what it thinks is an optimal overclock but
before clicking run click the little Cog wheel down below which is enabled in the
OC Scanner mode and play with the settings a bit they start a little too
high in my opinion although this may change by the time people get their
hands on it I set my test period to 5 Seconds my starting KZ offset to 200,000
my end to 250,000 and my step to 10,000
then I went back to the main screen and increased my power Target and
temperature Target to 100 12% and 92°
then it's time to click run what happens now is a firmar window will open and a
fuzzy EVGA logo will show up resulting in what Colton called Ms paint with
radar what a noob anyways this will stress out the graphics card and check
at a specific amount of voltage how much frequency the card can pump out by
increasing said frequency over the start amount by the step count that we set
earlier in that Cog wheel and retesting over and over and over again hopefully
recovering from crashes is mostly on its own now there are more features coming
like aggression percentage and stuff like that so you can have more
conservative but stable overclocks but
the performance increase over non overclocked is already pretty good
considering this was an entirely automated process after that I set
everything back to default and applied a manual overclock of my own increasing
the core clock by 200 MHz and the memory clock by 500 MHz this isn't the most
aggressive over I could have done but it was pretty Rock Solid and I'm
comfortable running both my 1080s at this speed so if you do it on your own
should probably be fine now my overclock beat the new OC Scanner automated
overclock but as automation isn't really the point I went back to the OC Scanner
found the result that it gave me and played around a bit by increasing a few
of the different frequency steps along the way mainly the ones near the top end
this actually helped me defeat my manual overclock albeit by a fairly minor
amount quickly and very easily now that
was actually pretty cool but at the same time the limit that the OC Scanner kept
on hitting so that it would stop was usually a power limit so while I'm happy
with the result we got now I'm even more excited for the results that we may get
from future cards like aftermarket Solutions with more power availability
I'm shooting this video before I leave for computex and I'm pretty sure it's
coming out after I come back so by the time you see this you will actually be
more informed than I currently am about
what cards will be available with potentially Higher Power Solutions so
here's hoping that that actually does happen does it give you the creeps when

it's actually kind of a big deal and stuff you can buy our t-shirts I link in
the video description down below go on the Forum and talk about graphics cards
and it destructive and non- Agro way and check out this video up here which was
the release video for our 1080 that will give you more information about just
like kind of the reference card and how it performs when it's not overclocked
