yeah there you go
today we are gonna take this pc
and overclock overvolt or otherwise
run beyond the manufacturer's specifications every single part of it
that we can some of the stuff we're gonna do will seriously improve
performance and some of it definitely won't big shout out to sonic
by the way for sponsoring this craziness
let's get started
so it shouldn't be news to most of you that the first thing you need when you're overclocking is a solid power
supply inadequate or unstable power can
adversely affect stability so we chose the seasonic prime titanium fanless a
seriously cool unit that is literally silent because it has
no fan so it's the first thing that we're going
to tune by plugging it into one of the
208 volt power outlets in the other unit
so we're running on 120 volt right now sucking about 270 watts
let's see what happens here
all right so after a quick cable swap here for this
beefy extension cord running out of the other room
we're running at about 190 volts so
there was some voltage drop and our same stress test
is now between 255 and
260 watts this doesn't make anything faster
but it does improve your system's efficiency though
probably not enough that i would if you're in north america like run out and
get 200 volt power put into your house now before doing anything else you're
gonna want your motherboard's latest BIOS so you can see ours is so new that
it has little animations in here you're also going to want the latest os updates
and a handful of tuning utilities then you want to get some baseline
readings in your preferred performance tests so you can make sure that any
efforts you're making any dials that you're turning are actually doing
something and that what they're doing is positive now we've done more detailed
CPU overclocking guides in the past so we're going to skip over some details
here but basically by adjusting our CPU
multiplier to 51 and disabling svid we were able to get
our core i5 8600k from 4.3 gigahertz on
all cores to 5.1 gigahertz with all cores active at
1.275 volts so that's only a
0.005 volt increase and it yields a 20
or higher improvement in our CPU tests
so we are off to a very good start
now this is usually where we stop tooling
around with the processor because CPU cache overclocking
doesn't really help much outside of very memory intensive applications but not
today after getting your CPU core dialed in
you can actually start upping the cache until it's at a similar frequency to the
core or until it causes uh
stability problems so ours was able to go from 4 to 4.8 gigahertz with a little
bit more CPU voltage which actually did
manage to give us a measurable boost in
cinebench now when it comes to RAM overclocking we
generally recommend staying away from xmp or other auto memory overclocking
since while sometimes it works so it can be worth a shot
other times it can be questionably stable
as for our kit well it's rated at 3200 megahertz and our overclocking result
was 3 200 megahertz even with extra voltage
so we didn't technically overclock our RAM but we did overclock our system past
the jdec ddr4 spec so
yeah we got an extra 27 points in cinebench
so we're going to call that a success from there
we did actually try fine-tuning the base
clock of the system as well but especially given that we already had
everything else like tuned to the red line it wasn't having
any of it this whole thing is on the knife's edge of stability
as it is so then with all the tuning we've done
so far what do we get for our trouble how has
this affected our gaming experience
turns out we've netted a whopping 1.2
percent increase in 3d mark times by and a whole two FPS
in far cry 5. so
it might be time to overclock our graphics my preferred strategy for this
is MSI afterburner in the foreground so we can make any adjustments that we'd
like and some kind of stress test running in windowed mode in the
background so we can monitor stability so you fire up afterburner grab that
there power knob and rip it all the way
to the max in our case it's like
112 some older gpus do let you go higher
then you incrementally increase the core clock until the system becomes unstable
so we landed on 150 megahertz for our
core for our memory clock we ended up with plus
275 so you do that right after your core
and this gave us more than a 10 frame per second increase in rise of the
tomb raider although
everything else hardly changed for some reason
that's kind of weird why is that well as it turns out NVIDIA's GPU boost 3
was already turboing the card up close to 2 gigahertz without our adjustments
that's much higher than the advertised 1683 that's because the cooling
capabilities of this card are able to sustain it so that means that without
overclocking you're actually getting close to the maximum performance you'd
be able to out of a modern card like a
which is great for most people but
overclockers without BIOS modding and
like physically modifying the card to apply more voltage to the GPU
don't get a lot of performance gains to brag about
so up until now everything has been like a nanaimo bar
just goodness but there has been one downside
thermals so under full load
our processor for instance is about 15 degrees celsius hotter
but what could we overclock
to make the computer cooler what if we were to give more voltage
to the fans so stashed in here where a hard drive
would normally go is something pretty special this is a dc
to dc converter so all we do is plug
standard molex 12 volt into this side
then alex is going to adjust this little potentiometer here
go for it nice whoa can you hear that
now we've got 17 volts coming out the
other side which is where we have our fans attached
so in ida 64 what kind of an improvement
will we see bam CPU temps down to 69 degrees a seven
degree improvement and all we had to give up was sound since this guy went
from like i don't know 20 decibels or so we're not sure since it was below the
sound floor of our office thanks in part to the fanless power supply up to 55
decibels which is around a normal conversation or an air conditioner this
also by the way won't help the lifetime of your fans our noctuas
actually might be fine but cheaper ones will likely end up letting out the magic
blue smoke before long so i think pretty much everything inside
the case is overclocked now but what about the things outside it
like your mouse and your keyboard and your monitor can they be overclocked
yes yes they can okay so for your mouse the
pulling rate in Windows is 125 hertz
meaning that there can be up to eight milliseconds of lag between moving your
mouse and it registering which can lead to noticeable delays in fast-paced games
in Windows 7 it was possible to overclock the polling rate on your usb
ports which could be great if your mouse
sensor could handle it but Windows 8 and up have changed the way that usb drivers
work and this is no longer possible fortunately a lot of gaming mouse
manufacturers have found ways to solve this problem for you since most of them
default to 500 hertz and you can use mouse rate to check yours for yourself
so click and move your mouse around
bippity boppity this is going to max out at 500.
there you have it now with that said
we can go higher this final mouse right here has a
firmware tool that you can grab we get one crack at this by the way so
uh and run
to flash it to a 1 000 hertz firmware
and then other mouse manufacturers like Corsair and razer have software tools
that work similarly let's just let this finish up and then
we'll see if it worked hey success
oh i can't even i can't even move it fast enough
to get all the way to a thousand okay whatever it's definitely over 500.
as for keyboards this is largely dependent on the manufacturer so this
Corsair one can actually be adjusted with this switch that's right on the
back of it bear in mind of course that the reason they make this so easy is
that it can affect compatibility with your system other keyboards
may not be possible to overclock at all
moving on to the monitor overclocking this is actually super easy if you've
got an NVIDIA card all you need to do is go into change resolution right here
then click customize tick enable resolutions not exposed by
the display and create yourself a custom resolution accepting all of the terms
and conditions and warnings that come along with it from here all you gotta do
is dial in a new refresh rate then click
test even a small increase over 60 hertz
like going to 70 or 75 should make a
very noticeable difference in games if you've got the GPU horsepower to drive
it now there ended up being a few things that you can't overclock like your SSD
or your hard drive like if you've got a 7200 RPM disc
that's all she's got and the closest thing would be buying a faster drive in
the first place like a wd velociraptor
that spins at 10 000 RPM
but like even that is much slower than an SSD also we tried pretty hard to get
the webcam overclocked and while it's technically possible to increase the FPS
while decreasing the resolution our logitech unit just
wouldn't play ball now
i was really on the fence about including this but alex insisted that we
include one last thing that you can overclock and it's probably the slowest
thing about your computer you
if you don't touch type learn to touch type also learn all of
the keyboard shortcuts that you can and if you're doing the same operation often
enough many modern keyboards allow you to
program it as a macro key you only have to press one button to execute it and
there's a joke here it's terrible since although you can't stop ai and machines
from taking over maybe you can use these tips and tricks to stay useful for a
little bit longer so big thanks to sea sonic for
sponsoring this video it's pretty freaking cool that they were able to
make a 600 watt power supply with literally zero noise
and that they were cool with us than putting a super loud system around it uh
thanks for watching you guys if this system this video sucked no the system doesn't
suck the system is cool if this video sucked you know what to do but if it was
awesome get subscribed hit that like button or check out the link to where to
buy the stuff we featured in the video description also down there is our merge
store which has cool shirts like this one and our community forum which you
should totally join all we've got to do
you're in you're in you got it oh you're not in yeah not quite
dang it alex like close to end okay you gotta you gotta finesse it okay you just
gotta get the pins kind of in there and then
you get a you're not in yet you know what you'll know when i'm in
well yeah
