00:00:00.399 --> 00:00:06.240
so you've been waiting for AMD ryzen now

00:00:04.359 --> 00:00:13.120
you've seen what it can do you're ready to do your best impression of Philip J

00:00:08.200 --> 00:00:16.160
fry but wait AMD has left the keys in

00:00:13.120 --> 00:00:19.080
the proverbial ignition and decided to

00:00:16.160 --> 00:00:25.000
keep their frequency multipliers unlocked so could you potentially save

00:00:21.920 --> 00:00:28.240
yourself a hundred bucks going for the

00:00:25.000 --> 00:00:30.279
1700x instead of the 1800x and get the

00:00:28.240 --> 00:00:36.800
same performance I always recommend that before you start

00:00:33.480 --> 00:00:39.600
haggling with your local CPU dealer you

00:00:36.800 --> 00:00:46.680
take her out for a test drive so let's do that then shall we Welcome to our AMD

00:00:42.920 --> 00:00:51.619
ryzen 7 overclocking

00:00:54.520 --> 00:01:02.160
Guide G fuel is the sugar-free energy drink formula that can help you maintain

00:00:59.359 --> 00:01:07.360
Focus during long work dayss and gaming sessions use offer code Linus to save

00:01:04.879 --> 00:01:13.960
40% for a limited time so since we don't have to spend

00:01:10.759 --> 00:01:17.200
extra on a special unlocked CPU to

00:01:13.960 --> 00:01:21.880
enable overclocking we can use any

00:01:17.200 --> 00:01:24.840
motherboard with an AMD x370 or b350

00:01:21.880 --> 00:01:32.600
chipset like our x370 based ASUS Crosshair 6 cool but what CPU should we

00:01:29.280 --> 00:01:35.920
buy well AMD's own guidance indicates

00:01:32.600 --> 00:01:39.200
that non-x chips aren't expected to

00:01:35.920 --> 00:01:42.680
overclock as well so The Logical course

00:01:39.200 --> 00:01:44.320
of action appears to be to just crank up

00:01:42.680 --> 00:01:50.560
the clocks on a 1700x and save ourselves a cnote but is

00:01:47.640 --> 00:01:56.680
it really going to be that easy in theory yes but it's complicated by the

00:01:53.640 --> 00:02:00.240
fact that ryzen doesn't give you very

00:01:56.680 --> 00:02:02.840
much control while you do have dead

00:02:00.240 --> 00:02:08.360
simple access to change the multiplier and the base clock the means by which

00:02:05.360 --> 00:02:11.480
the clock speed or frequency of a CPU is

00:02:08.360 --> 00:02:14.599
derived both in the BIOS and in AMD's

00:02:11.480 --> 00:02:17.720
ryzen master software you can't

00:02:14.599 --> 00:02:21.319
simultaneously enable AMD's automatic

00:02:17.720 --> 00:02:24.200
turbo functionality Precision boost

00:02:21.319 --> 00:02:29.319
ryzen immediately locks to the clock speed and voltage that you set meaning

00:02:27.160 --> 00:02:37.280
that if you want to actually match the potential of an 1800x your 1700x will

00:02:33.640 --> 00:02:40.480
have to be able to do up to 4.1 GHz all

00:02:37.280 --> 00:02:44.239
day long not an easy task considering

00:02:40.480 --> 00:02:47.200
even the 1800x will only hit 4.1 with

00:02:44.239 --> 00:02:54.920
xfr under certain workloads out of the box so let's get down to it then and see

00:02:50.440 --> 00:02:57.840
if our 1700x has what it takes using our

00:02:54.920 --> 00:03:03.200
usual ryzen bench and a 1080ti we'll Venture first into the BIOS for for the

00:03:00.159 --> 00:03:05.720
greatest degree of control simply by

00:03:03.200 --> 00:03:11.319
setting the multiplier to 40 and the vcor voltage to

00:03:07.959 --> 00:03:16.239
1.375 we managed a stable overclock of 4

00:03:11.319 --> 00:03:19.280
GHz over the 1700 X's stock 3.4 GHz base

00:03:16.239 --> 00:03:23.319
frequency not bad for a CPU that's only

00:03:19.280 --> 00:03:27.120
supposed to boost to 3.9 using

00:03:23.319 --> 00:03:29.480
xfr sadly though we couldn't push any

00:03:27.120 --> 00:03:35.519
further even if we cranked the voltage to

00:03:30.280 --> 00:03:38.439
AMD's recommended maximum of 1.45 volts

00:03:35.519 --> 00:03:43.080
we're not sure why this is exactly but even when we dove into more advanced

00:03:40.680 --> 00:03:51.280
base clock overclocking we were only able to eek out an extra 100 MHz on the

00:03:46.959 --> 00:03:54.000
CPU not really worth the time or effort

00:03:51.280 --> 00:04:00.120
the same was true of our 1800x which tells us that at least for our chips the

00:03:56.920 --> 00:04:02.400
limiting factor may be elsewhere

00:04:00.120 --> 00:04:07.879
armed with this knowledge we now know the relevant voltages and frequencies we

00:04:05.040 --> 00:04:14.120
need in order to perform an overclock first the CPU multiplier shown in our

00:04:10.640 --> 00:04:15.639
BIOS as CPU core ratio this works in

00:04:14.120 --> 00:04:23.479
increments of 0.25 and by default ranges from 22 to

00:04:20.440 --> 00:04:26.639
63.75 You'll generally want to ignore

00:04:23.479 --> 00:04:28.919
custom CPU core ratio but if you do use

00:04:26.639 --> 00:04:35.960
it you'll be greeted by a multiplier called fi ID and a divider called did

00:04:32.720 --> 00:04:39.759
which go from 16 to 255 and 8 to 48

00:04:35.960 --> 00:04:42.039
respectively to be clear the only reason

00:04:39.759 --> 00:04:46.960
you would want this kind of control is if you were base clock overclocking so

00:04:44.919 --> 00:04:52.440
you can access it with AI overclock tuner but quite frankly we don't really

00:04:50.160 --> 00:04:58.880
recommend it because it adjusts other sensitive system frequencies like PCI

00:04:55.280 --> 00:05:02.080
Express for no realworld performance

00:04:58.880 --> 00:05:04.800
benefit one useful thing you can do with

00:05:02.080 --> 00:05:12.960
the AI overclock tuner is set what ASUS calls docp which is fancy talk for Dr

00:05:09.479 --> 00:05:15.720
overclock profiles like Intel's

00:05:12.960 --> 00:05:20.639
XMP now in the future you'll be able to use this to set your high-speed RAM to

00:05:18.160 --> 00:05:26.319
the correct frequency and timings automatically which is key because ryzen

00:05:23.880 --> 00:05:31.520
really does seem to perform better the higher you can crank the memory speed

00:05:28.520 --> 00:05:34.759
and the lower you can get the timings

00:05:31.520 --> 00:05:37.319
but bear in mind that most RAM right now

00:05:34.759 --> 00:05:43.000
is tuned for Intel platforms so you'll need to shop for special memory to be

00:05:39.319 --> 00:05:45.919
able to take advantage of this

00:05:43.000 --> 00:05:51.280
and we actually didn't have a ton of success running even the memory that AMD

00:05:48.400 --> 00:05:58.199
provided or one of these AMD specific memory kits any higher than 2666

00:05:55.080 --> 00:06:01.560
megahertz so your mileage May

00:05:58.199 --> 00:06:04.120
significantly vary as far as that goes

00:06:01.560 --> 00:06:08.880
in any case it's likely you'll end up manually keying in your RAM timings to

00:06:06.560 --> 00:06:16.000
get them as low as you can before hitting a wall moving on to voltages our

00:06:12.160 --> 00:06:18.960
main concern is V cor shown here as CPU

00:06:16.000 --> 00:06:26.160
core voltage by default when you set an overclock ryzen will snap to a rather

00:06:22.440 --> 00:06:29.360
strange arbitrary voltage of

00:06:26.160 --> 00:06:30.319
13625 as for what to set it to we found

00:06:29.360 --> 00:06:35.960
that 1.375 is the sweet spot for overclocking

00:06:33.479 --> 00:06:43.319
with high-end air cooling while ASUS recommends no higher than 1. 1425 with

00:06:40.280 --> 00:06:46.680
strong liquid cooling drram voltage

00:06:43.319 --> 00:06:48.960
defaults to 1.2 but most higher end kits

00:06:46.680 --> 00:06:54.919
are asking for about 1.35 if you do adjust this you'll want

00:06:51.520 --> 00:06:56.319
to tweak the CPU s so voltage whose

00:06:54.919 --> 00:07:02.080
default is 0.99 turning this voltage up can improve

00:06:59.120 --> 00:07:06.759
memory overclocking and for us did seem to help with stability you'll also want

00:07:04.479 --> 00:07:14.199
to set your memory termination voltage in our case labeled VT DDR in Tweakers

00:07:09.919 --> 00:07:16.160
Paradise to half of your Dam voltage if

00:07:14.199 --> 00:07:20.440
you're trying out base clock overclocks then you can also find Sensi skew here

00:07:19.080 --> 00:07:23.840
which you'll want to enable Force stability though again we really don't

00:07:22.840 --> 00:07:30.879
recommend this pH okay so we're overclocked how

00:07:28.120 --> 00:07:37.960
does it run well thanks to the Crosshair 6's am3 mounting holes we can test not

00:07:34.000 --> 00:07:40.720
only our am4 based Noctua u12s and

00:07:37.960 --> 00:07:45.680
Cooler Master hyper 212 plus but also our Corsair h100i all-in-one water

00:07:43.479 --> 00:07:50.720
cooler so we can give you guys a good idea of what to expect pretty much

00:07:47.759 --> 00:07:56.639
across the board for temperatures under Ida 64's stability test our hyper 212

00:07:53.840 --> 00:08:01.879
plus managed 82° which I would consider to be acceptable while our Noctua ran at

00:07:58.879 --> 00:08:04.400
83 .5 so that's warmer but it should be

00:08:01.879 --> 00:08:11.199
noted that this was with a much quieter fan our h100i meanwhile managed to keep

00:08:08.120 --> 00:08:13.840
things down to a cozy 74 1

00:08:11.199 --> 00:08:20.000
12° if you want to compare these results to your own bear in mind that currently

00:08:16.479 --> 00:08:22.800
AMD's ryzen X Series CPUs are reporting

00:08:20.000 --> 00:08:28.000
temperatures a whole 20° higher than they actually are in some applications

00:08:25.720 --> 00:08:34.120
we took our readings from AMD's own ryzen Master software though so they

00:08:30.240 --> 00:08:38.279
should be accurate as for performance at

00:08:34.120 --> 00:08:40.959
4 GHz our 1700x sits at the top of the

00:08:38.279 --> 00:08:46.760
x-class rise and lineup for FPS per dollar at 1080p a likely Target for all

00:08:44.839 --> 00:08:52.240
of you out there buying High refresh rate monitors games like DSX mankind

00:08:49.720 --> 00:08:59.600
divided rise of the Tomb Raider for Honor GTA 5 and doom all showed close or

00:08:57.160 --> 00:09:05.839
better performance synthetics like like 7zip PC Mark y cruncher cinebench and

00:09:03.240 --> 00:09:13.320
real bench all showed the overclock mostly meeting or exceeding the 1800x

00:09:10.040 --> 00:09:16.640
sometimes by a wide margin so combining

00:09:13.320 --> 00:09:20.120
these scores and average FPS well it

00:09:16.640 --> 00:09:22.800
gets extremely close to the core i7 7700

00:09:20.120 --> 00:09:29.040
K's performance per dollar in many ways actually the

00:09:25.600 --> 00:09:33.880
overclocked ryzen 7 1700x reminds me of

00:09:29.040 --> 00:09:37.120
the XP 2500 plus it wasn't the fastest

00:09:33.880 --> 00:09:39.680
CPU on the market but it was fast enough

00:09:37.120 --> 00:09:45.519
for most uses and could be counted on to consistently overclock about as high as

00:09:42.320 --> 00:09:49.120
AMD's topof the line and more expensive

00:09:45.519 --> 00:09:52.160
3200 plus back then on top of that like

00:09:49.120 --> 00:09:55.680
the 2500 plus it's priced just right for

00:09:52.160 --> 00:09:59.720
a wide range of users consumers

00:09:55.680 --> 00:10:00.600
prosumers and Gamers so in short while

00:09:59.720 --> 00:10:05.839
some enthusiasts might have hoped that ryzen

00:10:03.440 --> 00:10:11.720
would overclock like a bat out of hell and be a return to the Athlon 64 in X2

00:10:08.959 --> 00:10:18.959
days with AMD on top of the performance Heap that isn't what we got but hey a

00:10:15.720 --> 00:10:21.760
chance to relive the Athlon XP days

00:10:18.959 --> 00:10:24.360
that's not too shabby either so thanks for watching guys if this video sucked
