welcome to the no messing around LGA 20113 overclocking guide we'll be
0:05
covering the benefits of overclocking the risks of overclocking and running
0:10
you guys through how exactly to do it with your shiny new Haswell e six core
0:15
or8 core
0:22
processor Corsair gaming RGB keyboards feature Precision Cherry MX RGB key
0:28

0:36
always starts with this but it's super important so we shouldn't skip it what
0:41
is overclocking what can we overclock
0:44
and why do we do it the short answers are for the first one basically it's
0:49
turning the speed up so that your PC components run faster than the
0:52
manufacturer intended and you can find more information about it here for
0:55
number two we'll turn up pretty much anything with a dial on it that makes it
0:59
Go FAS the CPU the RAM the graphics card are prime candidates and number three we
1:04
do it because we are driven to we have no self-control we know about the
1:09
drawbacks like higher heat output higher power consumption and even the potential
1:14
for Hardware degradation but we just have to have the
1:20
speed now no overclocking guide is complete without the latest and sexiest
1:24
Hardware as interesting as me pulling out a Northwood 2.4 C and cranking that
1:29
baby up might be to some people most of you are probably watching this today
1:34
because you want to actually do some performance tuning on Hardware that
1:38
you're actually using so as always it starts with the focus of today's video
1:43
the CPU normally for these guides we use an extreme Edition because the procedure
1:48
is actually the same for an extreme Edition or for a kseries processor
1:51
anyway but today is a little different today we're going to tune the core
1:55
i75820k because I think it's the best
1:59
bang for the processor on the market for enthusiasts and prosumers with workloads
2:04
that can benefit from its six processing cores but don't have the budget for its
2:09
eight core monster of a big brother the core i7
2:12
5960x to go along with its six cores at 3.3 to 3.6 GHz the 5820k has 15 Megs of
2:19
cache support for up to 64 gigs of ddr4
2:22
memory running in Quad Channel mode and 28 PCI Express 3.0 lanes for multiple
2:28
graphics cards or other expansion cards
2:31
this is less than the 5930k and the 5960x which each have 40 Lanes but as we
2:37
demonstrated here this will only matter in certain fairly unusual situations
2:43
let's move on to our next extreme Hardware selection if you've been
2:47
watching this channel for any amount of time you'll probably already know what Corsair dominators are here's a clip of
2:52
an old kit we painted to take advantage of their built-in custom lighting
2:57
effects in nutshell there were Corsair
3:00
biggest baddest sexiest DDR3 memory modules and now they're back for more
3:04
with ddr4 flavors available in capacities from 16 to 64 gigs and speeds
3:09
up to a blistering 3,300 MHz although the 32 gig kit here we've got today runs
3:14
at a mirror 2660 MHz cl15 out of the box
3:18
with its XMP 2.0 profile which of course
3:21
will only work with proper support from the motherboard which leads us to the
3:25
finest motherboard I've ever had the pleasure of using the Republic of Gamers
3:29
Rampage 5 extreme from ASUS now ASUS has
3:32
done no compromises Rampage grade boards
3:36
before but while they always had the performance features for extreme
3:40
overclockers they'd always be lacking the latest high-end onboard sound
3:44
designs from the formula grade Rog boards or the premium onboard Wi-Fi from
3:49
Deluxe grade boards not this time if you
3:52
can afford one you can buy a rampage 5 extreme knowing that you've got it all a
3:57
susus OC socket with extra pin for improved power delivery and RAM
4:01
overclocking their fourth generation digital power delivery their OC Zone
4:05
with some features that are actually amazingly useful even for beginners like
4:09
the safe boot Button that lets you boot to default settings without losing the
4:13
changes you just made when your overclock fails and some stuff that's
4:16
more for the hardcores like the onboard voltage probe contact points you get
4:21
top-of-the-line storage with eight SATA 3 ports two SATA Express ports and an
4:25
m.2 slot the latest Supreme effects 2014
4:28
onboard audio and finally finally three spatial stream AC Wireless with which I
4:34
achieved sustained transfer speeds of over 40 megabytes per second during
4:39
testing what oh and I guess you also get support for three-way SLI and Crossfire
4:44
with this CPU and four-way support with the 40 PCI Express Lane ones no big
4:48
whoop though for cooling I went with a Corsair h100i dual 120 mm fan all-in-one
4:54
water cooling system which is basically where I would suggest starting for six
4:59
core core overclocking with dual 140 mm
5:02
fan designs like the Corsair h110 or Cooler Master nepton 280l being solid
5:08
step UPS power was taken care of by a corser
5:12
hx1000i yes it's Overkill but I guess this is more of a because we can
5:16
Hardware Choice 0 plus Platinum efficiency dead silent operation at
5:21
light and medium loads a fully modular design and Corsair link integration for
5:25
all the real-time monitoring goodness you could want from a power supply and
5:29
that pretty much does it for the components that affect overclocking but
5:32
it should be noted that for before and after benchmarks a GTX 780 Ti graphics
5:37
card running at stock speeds was used
5:41
all right lonus so I got all my gear in front of me now what well start by
5:45
mashing delete while booting to enter the ufi BIOS and press F7 to get into
5:50
advanced mode right away none of that easy mode stuff for us no sir head over
5:55
to boot and under setup mode select Advanced so you won't have have to
5:59
switch manually every time you start up the system then it's time to head over
6:04
to the extreme tweaker heading where we'll be spending most of our time you
6:09
can save yourself a lot of effort by starting from a probably safe overclock
6:14
rather than beginning the tuning process from stock speed and testing at every
6:18
stage for hasbell processors I'd recommend a multiplier of 45 a CPU
6:23
voltage of around 1.3 volts and this is very important everything else in the
6:28
system at default settings then press F10 to apply your settings and restart
6:33
into Windows use CPU Z to verify that
6:36
the settings were applied correctly and run the stress testing application of
6:40
your choice dialing in one component at a time will take some of the guest work
6:45
out later when you're trying to balance how hard you're pushing each component
6:50
to achieve the best overall results just
6:53
make sure that your benchmark by the way is a safe one recent versions of prime
6:57
95 for example can cause your CPU to pull so much power in an overclocked
7:02
overvolted environment that you're sure to do long-term damage if you use it
7:06
extensively I'm partial to Ida 64 but a
7:10
susa's own R reel bench is a solid Choice as well and it's free if the test
7:15
fails in the first 10 minutes or so then it's time to go back to the ufi BIOS and
7:20
try a lower multiplier or as long as
7:23
your CPU low temperatures are within your comfort zone we're going to use 80°
7:27
as a Max for this guide you can try try slowly turning up the CPU voltage to see
7:32
if that helps and then boot back into Windows and rerun your test if the test
7:37
passes then it's time to restart and go back to the ufi BIOS anyway because it's
7:42
time to turn up your memory Speed Most performance kits these days will have
7:46
XMP profiles for easy RAM tuning and our
7:49
Corsair Dominator Platinum kit here is no exception with two separate profiles
7:54
a more conservative one and a more aggressive one with higher voltages but
7:59
what you need to watch out for is the changes in other system settings when
8:04
you switch your OC tuner mode from manual to XMP for RAM speeds below 2400
8:10
MHz and including 2400 MHz you can skip this next part but for speeds above 2400
8:16
MHz like our RAM it's very likely that your CPU strap will change to 125 MHz
8:23
this is okay but it means that your CPU clock speed will now be calculated by
8:28
multiplying the core rtio itio by 125 rather than by 100 so you will want
8:33
to keep XMP off for now and rify that
8:38
4.5 GHz stability test by setting your multiplier to
8:42
36 with that verified it's time to go
8:45
back into the UEFI BIOS and turn XMP back on and this now applies to all RAM
8:51
speeds again and then rerun the stability test if it fails or the system
8:55
refuses to power on consistently with error code BD then you might be tempted
9:00
to crank RAM voltage but I'd probably keep that around 1.4 volts Max and
9:06
suggest that you may want to consider fine-tuning the system agent voltage
9:10
instead I found I got dramatically better stability with around 1.02 volts
9:15
but your mileage may vary and bear in mind that more is not necessarily better
9:20
here it's more of a tuning process if
9:23
after tuning sa it passes then great
9:27
back to the BIOS you go now to see if the CPU has a little bit more Headroom
9:31
left in her you can raise the multiplier until your stress tests are no longer
9:36
able to pass now in doing that you might
9:40
notice at this stage that the CPU ratios don't give you very granular control so
9:45
if your chip handles for example 4.7 GHz
9:48
fine but 4.8 GHz crashes after a few
9:51
minutes and you want to reach your optimal setting probably somewhere in
9:55
between those two values then this is a great time to play around with base
9:59
clock a little bit and I really do mean
10:03
a little bit my chip handled 4.75 GHz
10:07
with Rock Solid stability when I reached a base clock of
10:10
101 which is as high as I really want okay you can go higher than that but you
10:14
don't want to play around with it too much because tinkering with base clock
10:17
outside of using standard dividers is not recommended because it affects many
10:22
other buses some of which like storage
10:25
for example don't take kindly to being
10:28
over clocked once you've got your CPU dialed in it's time to play around with
10:33
memory now if you want I personally
10:36
found ASUS's Auto profiles did a great job and between that and XMP it was
10:40
running fast enough but if you want you
10:44
can try different RAM dividers and try further tuning RAM voltage and system
10:48
agent voltage again to overclock your memory frequency Honestly though you
10:53
might find your time better spent trying to push for tighter RAM timings it
10:58
usually results in very similar performance gains which you can measure
11:02
by lowering the timings preferably one at a time and observing performance and
11:06
stability and memory dependent benchmarks and is less likely to debal
11:11
your overclock that you just tuned on your CPU because some RAM dividers are
11:16
inherently more stable than others 2400 is a good one as are 2666 2933 and 3200
11:24
if your memory can handle it but 2800 has trouble with some CPUs in including
11:29
RS even with kits that support that speed something very important to note
11:34
here talking about memory dividers is that increasing the CPU strap to 125
11:39
with the memory at 2400 does not change your memory divider so even though this
11:45
RAM speed increases to 3,000 MHz this is
11:48
still a good stable divider the ratio is
11:53
as important to stability as the actual speed it's running at but at the end of
11:58
the day memory find tuning is not something I personally do a lot of you
12:01
can refer back to my DDR3 versus ddr4 Apples to Apples comparison but for a
12:06
daily driver system it just doesn't matter much and the kind of instability
12:11
it causes situations where you can run a stress test for 12 hours perfectly fine
12:17
only to have it fail at 12 hours and 5 minutes is just not worth the time it
12:22
takes to verify that the system is actually running correctly
12:26
IMO usually CPU tuning aside from being
12:30
the part where you get the real tangible performance games is also much easier to
12:35
verify through stress testing so sticking with that is not a Bad Bet
12:38
speaking of the CPU one other thing you can fine-tune at this stage is the CPU
12:43
cash Ratio or uncore again it frankly
12:46
matters very little as far as performance compared to you know if you
12:51
just increase the CPU's raw frequency but if you can bring your cach speed up
12:55
closer to your CPU speed it can help a little bit with some performance metrics
13:00
once you change this though you may find that you need to fine-tune CPU voltage
13:04
and system agent voltage again so now
13:07
it's time to have a look at some performance numbers I'm not going to be
13:11
doing a huge test Suite here or anything but I'd like to give you guys a look at
13:15
the benefits of overclocking if you're willing to put a little bit of time into
13:18
it I also included numbers for ASUS's auto overclocking TPU thing that my ws
13:24
and Deluxe boards have but take them with a gigantic grain of salt the
13:29
performance numbers look good but that system wasn't stable at all at these
13:34
settings a departure from my normally positive experience with ASUS's autot
13:38
tuning so there you have it enabling XMP
13:41
on your memory doesn't do a whole lot compared to just running JX speeds this
13:45
platform is really not memory bandwidth limited even with six or eight cores to
13:49
feed thanks to its quad Channel memory capability tuning CPU speed up makes a
13:54
huge difference except for gaming where we really aren't CPU bottlenecked in the
13:58
first place anyway and further tuning RAM makes very little difference with
14:03
conservative easily stabilized RAM settings with more emphasis on the
14:08
impactful and easier to tune CPU frequency being the way to go as usual
14:13
so I think that pretty much wraps it up if you followed along with this guide
14:17
good job enjoy your freshly overclocked CPU I hope your results were awesome and
14:22
if they weren't then don't worry there's a good chance it wasn't your fault
14:25
anyway since the Silicon Lottery dictates that odds of getting a CPU with
14:30
more or less overclock ability was probably just you know predetermined by
14:36
the overclocking Gods anyway and probably wasn't your fault so don't stop
14:40
tuning though and better luck next time thank you guys for watching our x99
