oh overclocking the common excuse for so many Tech enthusiasts to spend just a
0:05
lot more on their rig this time however I'll be talking about overclocking
0:09
something specific a GTX 1080 spoiler
0:12
alot alute spoiler alert it overclocks
0:16
quite well but there's a wild card here NVIDIA introduced GPU boost 3.0 and it's
0:21
a whole new Beast
0:32
cooler Master's master case maker 5 features the free form modular system
0:36
for nearly unlimited customization learn more in the link in the video
0:40
description to explain GPU boost 3 we need to give some information about GPU
0:45
boost 2 your graphics card would dynamically change its frequency across
0:49
a linear frequency offset curve this is the curve that you would increase across
0:54
the board due to it being linear whenever you applied an overclock of say
0:58
50 or 100 or ever it was on that little
1:01
slider that you had before and then based on the load that's on your card
1:04
your frequency would fluctuate along that curve this is generally quite a
1:09
good system but it sometimes falls short because it doesn't crank your clock
1:13
speeds up to its potential maximum for
1:16
every single possible voltage level and these voltage levels will dynamically
1:21
change based on things like temperature power and a whole bunch of other stuff
1:25
so odds are you're losing performance
1:28
somewhere so G GPU boost 3 alongside
1:31
other more General improvements over GPU boost 2 allows us to either overclock
1:35
the old way with linear offset curves or break away from that linear offset curve
1:40
and tune things per voltage Point what
1:44
okay so that's kind of rather confusing sorry about that let's actually do some
1:48
stuff and hopefully it will make more sense the feature that helps you do
1:52
these things is called OC Scanner within the EVGA Precision app which is the only
1:56
one that supports it so far although I'm sure it will become ubiquitous soon
2:01
within the scanner there are three different modes basic mode applies a set
2:05
frequency offset to all voltage points linear mode allows users to linearly
2:10
increase the clock offset after choosing a start and end point and then it gets
2:15
interesting with manual mode which first off it's fairly self-explanatory you
2:19
manually input values for frequency at each voltage step but it also enables
2:24
the Run button which is where the fun begins this will run an automatic test
2:28
that will determine and apply what it thinks is an optimal overclock but
2:33
before clicking run click the little Cog wheel down below which is enabled in the
2:37
OC Scanner mode and play with the settings a bit they start a little too
2:41
high in my opinion although this may change by the time people get their
2:45
hands on it I set my test period to 5 Seconds my starting KZ offset to 200,000
2:51
my end to 250,000 and my step to 10,000
2:55
then I went back to the main screen and increased my power Target and
2:58
temperature Target to 100 12% and 92°
3:02
then it's time to click run what happens now is a firmar window will open and a
3:06
fuzzy EVGA logo will show up resulting in what Colton called Ms paint with
3:10
radar what a noob anyways this will stress out the graphics card and check
3:15
at a specific amount of voltage how much frequency the card can pump out by
3:19
increasing said frequency over the start amount by the step count that we set
3:24
earlier in that Cog wheel and retesting over and over and over again hopefully
3:28
recovering from crashes is mostly on its own now there are more features coming
3:33
like aggression percentage and stuff like that so you can have more
3:36
conservative but stable overclocks but
3:39
the performance increase over non overclocked is already pretty good
3:43
considering this was an entirely automated process after that I set
3:47
everything back to default and applied a manual overclock of my own increasing
3:52
the core clock by 200 MHz and the memory clock by 500 MHz this isn't the most
3:58
aggressive over I could have done but it was pretty Rock Solid and I'm
4:02
comfortable running both my 1080s at this speed so if you do it on your own
4:07
should probably be fine now my overclock beat the new OC Scanner automated
4:12
overclock but as automation isn't really the point I went back to the OC Scanner
4:17
found the result that it gave me and played around a bit by increasing a few
4:21
of the different frequency steps along the way mainly the ones near the top end
4:26
this actually helped me defeat my manual overclock albeit by a fairly minor
4:30
amount quickly and very easily now that
4:33
was actually pretty cool but at the same time the limit that the OC Scanner kept
4:38
on hitting so that it would stop was usually a power limit so while I'm happy
4:43
with the result we got now I'm even more excited for the results that we may get
4:48
from future cards like aftermarket Solutions with more power availability
4:53
I'm shooting this video before I leave for computex and I'm pretty sure it's
4:57
coming out after I come back so by the time you see this you will actually be
5:02
more informed than I currently am about
5:05
what cards will be available with potentially Higher Power Solutions so
5:11
here's hoping that that actually does happen does it give you the creeps when
5:16
your internet provider tracks your web browsing today's lack of online privacy
5:20
brings out your inner grizzly bear then you should try tunnel bear tunnel bear
5:25
is a simple VPN app that makes it easy to browse privately and enjoy a more
5:29
open internet with tunnel bear turned on your Wi-Fi connection is secured and
5:34
your online activity is kept private from your internet provider and people
5:39
like advertisers that are trying to look up and track people so they can Target
5:43
advertisements on you and sell that information to other people which you don't necessarily want and then profit
5:48
from that data sale tunnel bear has a topr rated privacy policy and does not
5:52
log your activity try for free with 500
5:56
megabytes and no credit card required and if you choose to get unlimited data
5:59
you can save 10% by going to Tunnel bear.com
6:04
LT if you like the video like it if you dislike the video and you're like I
6:08
don't want to performance tune my graphics card you're dumb you can do
6:12
that you can also subscribe if you want to see more of our coverage on after market 1080 cards and everything else to
6:18
be completely honest go to Amazon use our affiliate code that helps us a ton
6:22
it's actually kind of a big deal and stuff you can buy our t-shirts I link in
6:26
the video description down below go on the Forum and talk about graphics cards
6:29
and it destructive and non- Agro way and check out this video up here which was
6:33
the release video for our 1080 that will give you more information about just
6:37
like kind of the reference card and how it performs when it's not overclocked
