00:00:00.080 --> 00:00:07.879
oh overclocking the common excuse for so many Tech enthusiasts to spend just a

00:00:05.160 --> 00:00:12.559
lot more on their rig this time however I'll be talking about overclocking

00:00:09.559 --> 00:00:16.000
something specific a GTX 1080 spoiler

00:00:12.559 --> 00:00:18.119
alot alute spoiler alert it overclocks

00:00:16.000 --> 00:00:23.530
quite well but there's a wild card here NVIDIA introduced GPU boost 3.0 and it's

00:00:21.279 --> 00:00:32.000
a whole new Beast

00:00:32.000 --> 00:00:38.920
cooler Master's master case maker 5 features the free form modular system

00:00:36.239 --> 00:00:43.360
for nearly unlimited customization learn more in the link in the video

00:00:40.399 --> 00:00:47.399
description to explain GPU boost 3 we need to give some information about GPU

00:00:45.399 --> 00:00:52.520
boost 2 your graphics card would dynamically change its frequency across

00:00:49.760 --> 00:00:56.280
a linear frequency offset curve this is the curve that you would increase across

00:00:54.359 --> 00:01:01.519
the board due to it being linear whenever you applied an overclock of say

00:00:58.480 --> 00:01:03.559
50 or 100 or ever it was on that little

00:01:01.519 --> 00:01:07.080
slider that you had before and then based on the load that's on your card

00:01:04.960 --> 00:01:11.640
your frequency would fluctuate along that curve this is generally quite a

00:01:09.560 --> 00:01:16.479
good system but it sometimes falls short because it doesn't crank your clock

00:01:13.479 --> 00:01:19.360
speeds up to its potential maximum for

00:01:16.479 --> 00:01:23.240
every single possible voltage level and these voltage levels will dynamically

00:01:21.200 --> 00:01:28.479
change based on things like temperature power and a whole bunch of other stuff

00:01:25.439 --> 00:01:31.520
so odds are you're losing performance

00:01:28.479 --> 00:01:33.399
somewhere so G GPU boost 3 alongside

00:01:31.520 --> 00:01:38.479
other more General improvements over GPU boost 2 allows us to either overclock

00:01:35.799 --> 00:01:44.920
the old way with linear offset curves or break away from that linear offset curve

00:01:40.840 --> 00:01:46.719
and tune things per voltage Point what

00:01:44.920 --> 00:01:50.119
okay so that's kind of rather confusing sorry about that let's actually do some

00:01:48.640 --> 00:01:54.439
stuff and hopefully it will make more sense the feature that helps you do

00:01:52.240 --> 00:01:58.960
these things is called OC Scanner within the EVGA Precision app which is the only

00:01:56.799 --> 00:02:02.880
one that supports it so far although I'm sure it will become ubiquitous soon

00:02:01.399 --> 00:02:08.560
within the scanner there are three different modes basic mode applies a set

00:02:05.600 --> 00:02:13.160
frequency offset to all voltage points linear mode allows users to linearly

00:02:10.840 --> 00:02:17.640
increase the clock offset after choosing a start and end point and then it gets

00:02:15.280 --> 00:02:21.920
interesting with manual mode which first off it's fairly self-explanatory you

00:02:19.560 --> 00:02:26.400
manually input values for frequency at each voltage step but it also enables

00:02:24.280 --> 00:02:30.440
the Run button which is where the fun begins this will run an automatic test

00:02:28.640 --> 00:02:35.080
that will determine and apply what it thinks is an optimal overclock but

00:02:33.000 --> 00:02:39.599
before clicking run click the little Cog wheel down below which is enabled in the

00:02:37.560 --> 00:02:43.440
OC Scanner mode and play with the settings a bit they start a little too

00:02:41.680 --> 00:02:47.720
high in my opinion although this may change by the time people get their

00:02:45.040 --> 00:02:55.440
hands on it I set my test period to 5 Seconds my starting KZ offset to 200,000

00:02:51.159 --> 00:02:56.920
my end to 250,000 and my step to 10,000

00:02:55.440 --> 00:03:02.440
then I went back to the main screen and increased my power Target and

00:02:58.440 --> 00:03:04.319
temperature Target to 100 12% and 92°

00:03:02.440 --> 00:03:08.599
then it's time to click run what happens now is a firmar window will open and a

00:03:06.440 --> 00:03:13.280
fuzzy EVGA logo will show up resulting in what Colton called Ms paint with

00:03:10.760 --> 00:03:17.640
radar what a noob anyways this will stress out the graphics card and check

00:03:15.560 --> 00:03:22.200
at a specific amount of voltage how much frequency the card can pump out by

00:03:19.760 --> 00:03:26.959
increasing said frequency over the start amount by the step count that we set

00:03:24.599 --> 00:03:31.120
earlier in that Cog wheel and retesting over and over and over again hopefully

00:03:28.760 --> 00:03:35.000
recovering from crashes is mostly on its own now there are more features coming

00:03:33.040 --> 00:03:39.799
like aggression percentage and stuff like that so you can have more

00:03:36.720 --> 00:03:41.640
conservative but stable overclocks but

00:03:39.799 --> 00:03:45.280
the performance increase over non overclocked is already pretty good

00:03:43.319 --> 00:03:49.920
considering this was an entirely automated process after that I set

00:03:47.959 --> 00:03:55.480
everything back to default and applied a manual overclock of my own increasing

00:03:52.560 --> 00:04:01.000
the core clock by 200 MHz and the memory clock by 500 MHz this isn't the most

00:03:58.959 --> 00:04:05.239
aggressive over I could have done but it was pretty Rock Solid and I'm

00:04:02.799 --> 00:04:09.959
comfortable running both my 1080s at this speed so if you do it on your own

00:04:07.400 --> 00:04:14.519
should probably be fine now my overclock beat the new OC Scanner automated

00:04:12.000 --> 00:04:19.280
overclock but as automation isn't really the point I went back to the OC Scanner

00:04:17.320 --> 00:04:23.560
found the result that it gave me and played around a bit by increasing a few

00:04:21.560 --> 00:04:28.440
of the different frequency steps along the way mainly the ones near the top end

00:04:26.040 --> 00:04:33.960
this actually helped me defeat my manual overclock albeit by a fairly minor

00:04:30.560 --> 00:04:36.320
amount quickly and very easily now that

00:04:33.960 --> 00:04:40.479
was actually pretty cool but at the same time the limit that the OC Scanner kept

00:04:38.639 --> 00:04:46.039
on hitting so that it would stop was usually a power limit so while I'm happy

00:04:43.560 --> 00:04:50.280
with the result we got now I'm even more excited for the results that we may get

00:04:48.000 --> 00:04:55.680
from future cards like aftermarket Solutions with more power availability

00:04:53.600 --> 00:05:00.080
I'm shooting this video before I leave for computex and I'm pretty sure it's

00:04:57.199 --> 00:05:05.759
coming out after I come back so by the time you see this you will actually be

00:05:02.440 --> 00:05:07.960
more informed than I currently am about

00:05:05.759 --> 00:05:13.800
what cards will be available with potentially Higher Power Solutions so

00:05:11.320 --> 00:05:17.800
here's hoping that that actually does happen does it give you the creeps when

00:05:16.000 --> 00:05:23.319

00:06:08.319 --> 00:06:14.160
don't want to performance tune my graphics card you're dumb you can do

00:06:12.720 --> 00:06:20.720
that you can also subscribe if you want to see more of our coverage on after market 1080 cards and everything else to

be completely honest go to Amazon use our affiliate code that helps us a ton

00:06:22.479 --> 00:06:27.759
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

00:06:29.199 --> 00:06:36.000
and it destructive and non- Agro way and check out this video up here which was

00:06:33.759 --> 00:06:39.160
the release video for our 1080 that will give you more information about just

00:06:37.639 --> 00:06:43.199
like kind of the reference card and how it performs when it's not overclocked
