so you've been waiting for AMD ryzen now
you've seen what it can do you're ready to do your best impression of Philip J
fry but wait AMD has left the keys in
the proverbial ignition and decided to
keep their frequency multipliers unlocked so could you potentially save
yourself a hundred bucks going for the
1700x instead of the 1800x and get the
same performance I always recommend that before you start
haggling with your local CPU dealer you
take her out for a test drive so let's do that then shall we Welcome to our AMD
ryzen 7 overclocking
Guide G fuel is the sugar-free energy drink formula that can help you maintain
Focus during long work dayss and gaming sessions use offer code Linus to save
40% for a limited time so since we don't have to spend
extra on a special unlocked CPU to
enable overclocking we can use any
motherboard with an AMD x370 or b350
chipset like our x370 based ASUS Crosshair 6 cool but what CPU should we
buy well AMD's own guidance indicates
that non-x chips aren't expected to
overclock as well so The Logical course
of action appears to be to just crank up
the clocks on a 1700x and save ourselves a cnote but is
it really going to be that easy in theory yes but it's complicated by the
fact that ryzen doesn't give you very
much control while you do have dead
simple access to change the multiplier and the base clock the means by which
the clock speed or frequency of a CPU is
derived both in the BIOS and in AMD's
ryzen master software you can't
simultaneously enable AMD's automatic
turbo functionality Precision boost
ryzen immediately locks to the clock speed and voltage that you set meaning
that if you want to actually match the potential of an 1800x your 1700x will
have to be able to do up to 4.1 GHz all
day long not an easy task considering
even the 1800x will only hit 4.1 with
xfr under certain workloads out of the box so let's get down to it then and see
if our 1700x has what it takes using our
usual ryzen bench and a 1080ti we'll Venture first into the BIOS for for the
greatest degree of control simply by
setting the multiplier to 40 and the vcor voltage to
1.375 we managed a stable overclock of 4
GHz over the 1700 X's stock 3.4 GHz base
frequency not bad for a CPU that's only
supposed to boost to 3.9 using
xfr sadly though we couldn't push any
further even if we cranked the voltage to
AMD's recommended maximum of 1.45 volts
we're not sure why this is exactly but even when we dove into more advanced
base clock overclocking we were only able to eek out an extra 100 MHz on the
CPU not really worth the time or effort
the same was true of our 1800x which tells us that at least for our chips the
limiting factor may be elsewhere
armed with this knowledge we now know the relevant voltages and frequencies we
need in order to perform an overclock first the CPU multiplier shown in our
BIOS as CPU core ratio this works in
increments of 0.25 and by default ranges from 22 to
63.75 You'll generally want to ignore
custom CPU core ratio but if you do use
it you'll be greeted by a multiplier called fi ID and a divider called did
which go from 16 to 255 and 8 to 48
respectively to be clear the only reason
you would want this kind of control is if you were base clock overclocking so
you can access it with AI overclock tuner but quite frankly we don't really
recommend it because it adjusts other sensitive system frequencies like PCI
Express for no realworld performance
benefit one useful thing you can do with
the AI overclock tuner is set what ASUS calls docp which is fancy talk for Dr
overclock profiles like Intel's
XMP now in the future you'll be able to use this to set your high-speed RAM to
the correct frequency and timings automatically which is key because ryzen
really does seem to perform better the higher you can crank the memory speed
and the lower you can get the timings
but bear in mind that most RAM right now
is tuned for Intel platforms so you'll need to shop for special memory to be
able to take advantage of this
and we actually didn't have a ton of success running even the memory that AMD
provided or one of these AMD specific memory kits any higher than 2666
megahertz so your mileage May
significantly vary as far as that goes
in any case it's likely you'll end up manually keying in your RAM timings to
get them as low as you can before hitting a wall moving on to voltages our
main concern is V cor shown here as CPU
core voltage by default when you set an overclock ryzen will snap to a rather
strange arbitrary voltage of
13625 as for what to set it to we found
that 1.375 is the sweet spot for overclocking
with high-end air cooling while ASUS recommends no higher than 1. 1425 with
strong liquid cooling drram voltage
defaults to 1.2 but most higher end kits
are asking for about 1.35 if you do adjust this you'll want
to tweak the CPU s so voltage whose
default is 0.99 turning this voltage up can improve
memory overclocking and for us did seem to help with stability you'll also want
to set your memory termination voltage in our case labeled VT DDR in Tweakers
Paradise to half of your Dam voltage if
you're trying out base clock overclocks then you can also find Sensi skew here
which you'll want to enable Force stability though again we really don't
recommend this pH okay so we're overclocked how
does it run well thanks to the Crosshair 6's am3 mounting holes we can test not
only our am4 based Noctua u12s and
Cooler Master hyper 212 plus but also our Corsair h100i all-in-one water
cooler so we can give you guys a good idea of what to expect pretty much
across the board for temperatures under Ida 64's stability test our hyper 212
plus managed 82° which I would consider to be acceptable while our Noctua ran at
83 .5 so that's warmer but it should be
noted that this was with a much quieter fan our h100i meanwhile managed to keep
things down to a cozy 74 1
12° if you want to compare these results to your own bear in mind that currently
AMD's ryzen X Series CPUs are reporting
temperatures a whole 20° higher than they actually are in some applications
we took our readings from AMD's own ryzen Master software though so they
should be accurate as for performance at
4 GHz our 1700x sits at the top of the
x-class rise and lineup for FPS per dollar at 1080p a likely Target for all
of you out there buying High refresh rate monitors games like DSX mankind
divided rise of the Tomb Raider for Honor GTA 5 and doom all showed close or
better performance synthetics like like 7zip PC Mark y cruncher cinebench and
real bench all showed the overclock mostly meeting or exceeding the 1800x
sometimes by a wide margin so combining
these scores and average FPS well it
gets extremely close to the core i7 7700
K's performance per dollar in many ways actually the
overclocked ryzen 7 1700x reminds me of
the XP 2500 plus it wasn't the fastest
CPU on the market but it was fast enough
for most uses and could be counted on to consistently overclock about as high as
AMD's topof the line and more expensive
3200 plus back then on top of that like
the 2500 plus it's priced just right for
a wide range of users consumers
prosumers and Gamers so in short while
some enthusiasts might have hoped that ryzen
would overclock like a bat out of hell and be a return to the Athlon 64 in X2
days with AMD on top of the performance Heap that isn't what we got but hey a
chance to relive the Athlon XP days
that's not too shabby either so thanks for watching guys if this video sucked
