00:00:07.399 --> 00:00:15.040
welcome to my introduction of the OC certified concept featuring The MSI Big

00:00:12.160 --> 00:00:18.880
Bang z77 M power now I'm going to quickly explain the difference between

00:00:16.920 --> 00:00:22.519
what we've seen in the past and what we are seeing now because they are

00:00:20.439 --> 00:00:27.199
incredibly different in the past we've seen military class components high

00:00:25.000 --> 00:00:30.920
quality components that are optimized for overclocking optimized for

00:00:28.880 --> 00:00:36.360
performance all that good stuff we've seen digital power phases and you know

00:00:34.200 --> 00:00:40.680
golden capacitors and all kinds of crazy stuff in the past before from not only

00:00:37.879 --> 00:00:45.520
MSI but everyone but OC certified takes all that theoretically this stuff should

00:00:42.920 --> 00:00:51.480
be good and steps it up to a whole new level every single Board gets hand

00:00:48.840 --> 00:00:56.440
tested at an overclocked setting in a nonideal environment with prime 95

00:00:53.879 --> 00:01:00.440
that's right a true Enthusiast stability testing program and we're going to be

00:00:58.120 --> 00:01:04.920
having a look at this board in in a real system in a real case with a real

00:01:03.039 --> 00:01:08.720
graphics card running real games to see what kind of a benefit we get from the

00:01:06.720 --> 00:01:15.000
easy overclocking experience that an OC certified board enables and comparing it

00:01:12.119 --> 00:01:20.040
to a non overclocked system to see what we can do with basically what amounted

00:01:17.000 --> 00:01:22.200
to about 15 minutes of overclocking and

00:01:20.040 --> 00:01:26.520
yeah it was amazingly easy now we're going to start with a bit of a product

00:01:23.479 --> 00:01:30.000
tour here guys so the z77 M power is

00:01:26.520 --> 00:01:31.960
sort of a step up from the z77a gd65

00:01:30.000 --> 00:01:36.280
five they actually Bear some similarity to each other in terms of the overall

00:01:34.079 --> 00:01:38.720
layouts of these boards the PCB designs and I apologize I'm going to have to

00:01:37.479 --> 00:01:43.560
cheat a little bit we're going to use a picture of the z77 M power and a reel

00:01:41.360 --> 00:01:48.079
board for the gd65 because the M power is in that system over there so the PCI

00:01:45.920 --> 00:01:51.719
Express slot layout is exactly the same however on the M Power you see some

00:01:49.560 --> 00:01:54.880
significant improvements so number one is that it does include Wireless

00:01:53.119 --> 00:02:00.960
connectivity what both Wi-Fi and Bluetooth it also has a beefier 12 phase

00:01:57.799 --> 00:02:03.399
hybrid there it is hybrid digital power

00:02:00.960 --> 00:02:08.280
design which the gd65 does not it is using only an 8-phase design so the

00:02:05.759 --> 00:02:11.800
digital hybrid power design allows higher power efficiency faster power

00:02:09.920 --> 00:02:16.440
transmission speed programmable has a programmable microprocessor inside and

00:02:13.840 --> 00:02:20.239
is optimized for extreme overclocking okay it has better cooling yeah not

00:02:18.760 --> 00:02:25.000
significantly better cooling but it does have better cooling it's got a superpipe

00:02:21.800 --> 00:02:26.760
whereas the dd65 did not it has I think

00:02:25.000 --> 00:02:30.640
a way better color scheme especially cuz it matches that GTX 680 lightning that

00:02:29.400 --> 00:02:36.400
I've gotten there I'm going to pull off the side panel later and show you guys it's outstanding it has a thicker PCB

00:02:34.879 --> 00:02:41.920
which basically amounts to better power stability so again better overclocking

00:02:39.319 --> 00:02:48.200
six rear USB 3 there it is whereas the gd65 I believe

00:02:45.159 --> 00:02:51.720
only has two rear usb3 ports there they

00:02:48.200 --> 00:02:53.599
are okay and it also has total fan

00:02:51.720 --> 00:02:57.519
control so all the fan headers are using pwm connectivity and finally it is

00:02:56.000 --> 00:03:03.200
Windows 8 certified now some of the similar things are the onboard button OC

00:03:00.720 --> 00:03:07.840
Genie as well as V checkpoint so that means you can use your multi meter to

00:03:04.920 --> 00:03:12.879
actually check the voltages uh post LED readout as well as their multibio switch

00:03:11.040 --> 00:03:16.200
which has saved my bacon on this exact board when we had a power outage while

00:03:14.360 --> 00:03:20.080
we were flashing the BIOS all we had to do was switch to the other BIOS and we

00:03:17.799 --> 00:03:26.920
were good to go so overclocking this 3770k was easy peasy basically all I did

00:03:24.040 --> 00:03:31.799
was adjust the CPU ratio turn off some of the automatic Turbo Controls and

00:03:29.080 --> 00:03:37.159
whatnots ask my camera very nicely to focus on the screen for me change the

00:03:33.760 --> 00:03:38.439
memory to DDR 3600 MHz CPU core voltage

00:03:37.159 --> 00:03:48.560
to 1. 225 volts and that was it um now all we

00:03:45.239 --> 00:03:51.239
got to do is boot into Windows and see

00:03:48.560 --> 00:03:57.159
if we are stable now for the GPU because I was able to overvolt the core I was

00:03:52.720 --> 00:03:59.599
able to get a plus 236 MHz on the GPU

00:03:57.159 --> 00:04:03.079
boost for that lightning GTX 680 so that's where a lot of that extra

00:04:01.280 --> 00:04:06.480
performance is going to come from validating your overclock is essential

00:04:04.959 --> 00:04:10.200
there's a ton of tools out there I still use prime 95 I know it's a little bit

00:04:08.239 --> 00:04:15.360
oldfashioned but eight threads of prime 95 running for 24 to 48 hours you can

00:04:13.239 --> 00:04:18.799
make sure you use CPU Z to validate that you are running at the clock speed that

00:04:16.919 --> 00:04:22.560
you think you're running at and you can use real temp GT in order to make sure

00:04:20.600 --> 00:04:26.479
that your temperatures are acceptable would I rather have a liquid cooler on

00:04:24.320 --> 00:04:33.560
this particular setup and get those down to closer to 70 to 75° yes however 85°

00:04:31.720 --> 00:04:36.160
under an artificial load isn't going to kill it because you'll never see

00:04:34.720 --> 00:04:42.639
temperatures like this in a gaming environment or even when you're rendering video so I think that pretty

00:04:40.639 --> 00:04:47.600
much wraps it up for how to get your board running at 4.6 gz which is what

00:04:45.240 --> 00:04:51.520
they validated at at the factory so let's go ahead and do some testing now

00:04:50.080 --> 00:04:59.000
now I'd like to introduce the tests that I'm going to be running we're going to keep things pretty simple we're testing

00:04:55.080 --> 00:05:00.639
a core i7 3770k against another 3770k

00:04:59.000 --> 00:05:03.240
but this one over clocked so there's no difference in architecture here so we're

00:05:02.080 --> 00:05:09.400
just going to run a couple simple benchmarks we're also testing a GTX 680

00:05:06.600 --> 00:05:13.360
against a gtx680 so again no architectural change so we're just going

00:05:10.840 --> 00:05:18.039
to do a couple quick benchmarks to see what we gain by using overclocking

00:05:15.280 --> 00:05:21.720
optimized or certified components versus ones that aren't so if you guys don't

00:05:20.000 --> 00:05:25.919
already know the difference between the GTX 680 lightning the one in here with

00:05:24.080 --> 00:05:29.960
the massive heat pipes all over it as well as the dual fan cooler and just

00:05:28.039 --> 00:05:34.160
generally beastliness that it's got going on is more than anything else the

00:05:32.160 --> 00:05:39.120
fact that it supports triple over voltage so that means you can actually

00:05:35.840 --> 00:05:42.240
overvolt the GPU core unlike a reference

00:05:39.120 --> 00:05:44.479
GTX 680 this enables better overclocking

00:05:42.240 --> 00:05:48.400
and better stability and it also runs cool due to the fact that it's got the

00:05:46.080 --> 00:05:52.520
awesome full card back plate as well as again all the heat pipes and the beastly

00:05:50.800 --> 00:05:57.720
cooler that it's got going on I should run you through the rest of the testbench so we've got crucial

00:05:55.280 --> 00:06:02.120
ballistics tactical Tracer DDR3 memory going on in here which looks amazing

00:05:59.639 --> 00:06:05.560
there's those uh pwm phases for the motherboard that light up when it's

00:06:03.840 --> 00:06:10.520
underload so we are playing a game so that's why those are all lit up and the memor is going nuts as well there's our

00:06:08.759 --> 00:06:14.120
big bang board so I'm sorry I can't get you guys a better view of that we're

00:06:11.880 --> 00:06:19.919
using a simple air cooler from be quiet! it's not even particularly loud and

00:06:16.120 --> 00:06:21.319
we've got an ocz ZT 750 W power supply

00:06:19.919 --> 00:06:26.720
and we're running off of a mushkin Kronos Deluxe

00:06:24.240 --> 00:06:33.520
SSD so the configurations we'll be testing are stock 3770k with a stock

00:06:30.400 --> 00:06:36.400
gtx680 versus what we get with our quick

00:06:33.520 --> 00:06:40.599
overclock on the 3770k with the OC certified board and our maximum

00:06:38.800 --> 00:06:45.680
overclock we were able to achieve on the GTX 680 lightning edition see what we

00:06:43.599 --> 00:06:50.919
gain from a few minutes of overclocking for tests we'll be keeping it really

00:06:47.160 --> 00:06:53.759
simple crisis 2 The Elder Scrolls Skyrim

00:06:50.919 --> 00:07:00.840
and doing a 1 gig video output test converting to Windows

00:06:56.960 --> 00:07:03.840
media video and rendering so at non

00:07:00.840 --> 00:07:05.560
overclocked stock settings as well as

00:07:03.840 --> 00:07:11.840
with the overclocked CPU it's not overclocked now and the overclocked

00:07:08.520 --> 00:07:13.479
lightning GTX 680 so it's conclusion

00:07:11.840 --> 00:07:17.960
time and just for a lark I'm going to experiment with overlaying my

00:07:15.039 --> 00:07:22.720
performance graphs instead of just talking about them and pointing the

00:07:19.520 --> 00:07:25.240
camera at them so basically this test

00:07:22.720 --> 00:07:30.240
system is pretty beast and what benefit do we get from having our overclocked

00:07:27.440 --> 00:07:34.520
graphics card and overclocked CPU well the answer is it depends on the

00:07:31.720 --> 00:07:38.080
situation so for example in crisis 2 you can see the performance difference

00:07:35.960 --> 00:07:43.440
between our overclock system and our non- overclock system is only about 2 to

00:07:40.800 --> 00:07:48.520
10% so what this tells me because most of our overclocking was done with the

00:07:45.800 --> 00:07:54.280
Empower motherboard is that crisis 2 was not particularly CPU limited so

00:07:52.039 --> 00:07:58.919
fascinating so the GPU was more of a factor holding it back and the GPU clock

00:07:56.759 --> 00:08:01.960
speeds um didn't make that much of a difference so it's possible that the

00:08:00.639 --> 00:08:08.319
difference in performance could be more to do with the memory the lightning edition card didn't overclock that much

00:08:05.319 --> 00:08:11.039
on the memory only a few mehz so once we

00:08:08.319 --> 00:08:14.759
moved on to Skyrim you can see we see a significant performance difference about

00:08:12.840 --> 00:08:19.360
15 to 20% depending on whether you look at the

00:08:16.879 --> 00:08:24.720
minimum or the average frame rates that means that this overclocked certified

00:08:22.520 --> 00:08:29.599
quick overclock that we did is yielding us an enormous gain in performance that

00:08:27.560 --> 00:08:34.479
usually is reserved for upgrading to to an additional CPU now can you achieve

00:08:32.039 --> 00:08:41.440
this overclock on something other than a big bang z77 M Power the answer is

00:08:38.120 --> 00:08:44.200
probably you can however this one is

00:08:41.440 --> 00:08:49.240
validated and this one is ready to go so it's pretty much guaranteed out of the

00:08:46.760 --> 00:08:53.920
box as long as you don't get a total dud CPU now for our quick video rendering

00:08:51.720 --> 00:08:59.399
test we saw a 10% Improvement in performance so that indicates to me that

00:08:57.200 --> 00:09:04.640
the CPU is faster and we will therefore or save time if we are doing anything

00:09:01.200 --> 00:09:07.959
CPU intensive so in conclusion there's

00:09:04.640 --> 00:09:10.720
not much going on here in terms of the

00:09:07.959 --> 00:09:13.560
unexpected Intel CPUs are fast overclocking makes them faster and I

00:09:12.320 --> 00:09:21.760
hope you guys have found this to be educational and informative um especially about MSI's

00:09:18.720 --> 00:09:22.959
