1
00:00:02,600 --> 00:00:21,470
there no place there no moment

00:00:30,759 --> 00:00:37,079
welcome to my Devil's Canyon and Pentium anniversary edition overclocking guide

3
00:00:35,480 --> 00:00:41,399
now the drawbacks of overclocking your CPU are many overclockable Hardware is

4
00:00:39,600 --> 00:00:46,520
more expensive if it's done incorrectly it can cause your computer to blue screen or otherwise be unstable it makes

5
00:00:44,440 --> 00:00:50,440
your PC consume more power and output more heat it can make your processor not

6
00:00:48,480 --> 00:00:56,160
last as long it avoids the warranty on many components and finally doing it

7
00:00:53,199 --> 00:01:01,920
right can be down right time consuming so why do we do it because we want to go

8
00:00:59,239 --> 00:01:01,920
fast

9
00:01:02,680 --> 00:01:09,200
H now before we get into this guide when it comes to running things beyond their

10
00:01:07,240 --> 00:01:13,600
specifications I don't think I have to spell out that nothing is guaranteed so

11
00:01:11,920 --> 00:01:18,360
with that out of the way let's get into the parts we're using for our guide

12
00:01:15,159 --> 00:01:21,400
today for the CPU we actually have two

13
00:01:18,360 --> 00:01:23,040
different choices the first is a 4790k

14
00:01:21,400 --> 00:01:27,240
which is a quad core with hyperthread and clock do a little faster than the

15
00:01:24,799 --> 00:01:32,640
older 4770k from our last overclocking guide at 4 GHz base and up to 4.4 4 GHz

16
00:01:30,520 --> 00:01:36,360
boost it features an upgraded thermal solution for cooler temperatures versus

17
00:01:34,360 --> 00:01:40,640
its older brother and due to refinements in Intel's chip selection process

18
00:01:38,119 --> 00:01:45,320
promises more consistent overclocking results a fine Choice oh and like its

19
00:01:43,079 --> 00:01:49,600
predecessor it's a ker skew which means it's unlocked and overclocking ready

20
00:01:47,520 --> 00:01:54,200
which leads us into our second CPU the Pentium

21
00:01:50,840 --> 00:01:56,439
g3258 anniversary edition this chip is

22
00:01:54,200 --> 00:02:00,079
truly remarkable it's not the fanciest thing in the world with no

23
00:01:57,439 --> 00:02:06,880
hyperthreading only two processing cores and a mere 3.2 GHz stock clock speed but

24
00:02:03,439 --> 00:02:09,239
it's unlocked which means maybe a

25
00:02:06,880 --> 00:02:13,400
massive overclocking potential for cooling we're using a Corsair h100

26
00:02:11,760 --> 00:02:16,879
liquid cooler I recommend a good Tower air cooler or a dual fan all-in-one

27
00:02:15,400 --> 00:02:21,200
liquid cooler for the best overclocking results for our power supply we've gone

28
00:02:18,680 --> 00:02:26,760
with the Corsair ax850 we could have gone Overkill with the latest ax1 1500i

29
00:02:24,360 --> 00:02:30,840
but getting a gr overclock is not about having a high wattage power supply as

30
00:02:29,080 --> 00:02:34,319
much as it's about having a good quality one with stable rails and very little

31
00:02:32,360 --> 00:02:38,000
Ripple so this one will be okay the ax500 I would have been better but this

32
00:02:36,000 --> 00:02:42,480
one will be fine speaking of Overkill we've gone slightly overkill on the

33
00:02:39,800 --> 00:02:47,000
motherboard with a z97 WS from ASUS both Luke and I are very fond of WS series

34
00:02:45,040 --> 00:02:49,640
boards they're just so dependable and easy to work with they offer great

35
00:02:48,319 --> 00:02:56,200
compatibility with other components amazing build quality and while they lack some of the fancy extras that Ro or

36
00:02:54,360 --> 00:02:59,519
tough series boards might have they've got it where it counts and they'll

37
00:02:57,560 --> 00:03:03,120
overclock with the best of them these days the motherboard actually doesn't

38
00:03:01,040 --> 00:03:07,080
affect overclocking results much unless you're pushing things to the limits with

39
00:03:04,799 --> 00:03:10,640
exotic cooling anyway so as long as you pick an Aus motherboard you should be

40
00:03:08,920 --> 00:03:14,680
able to follow along with our guide exactly with other brand motherboards

41
00:03:13,040 --> 00:03:17,400
having similar options with just a little bit more digging required on your

42
00:03:16,080 --> 00:03:23,879
part to match up the stuff we're changing to how what it looks like on the other board finally for memory we're

43
00:03:20,959 --> 00:03:27,760
using an 8 gig kit of 2400 MHz gskill memory high-speed memory isn't a huge

44
00:03:25,840 --> 00:03:32,920
deal these days but with how much less expensive it's gotten lately compared to

45
00:03:29,799 --> 00:03:34,640
standard 1600 MHz stuff and how easy it

46
00:03:32,920 --> 00:03:39,120
is to dial in at high frequencies with XMP profiles we figured what the hate

47
00:03:37,239 --> 00:03:42,680
it's optional but we'll show it to you anyway okay lonus enough Preamble how do

48
00:03:41,840 --> 00:03:48,439
I overclock step one don't overclock start

49
00:03:46,640 --> 00:03:52,200
by updating your BIOS and drivers running a stress test for an hour or two

50
00:03:50,480 --> 00:03:55,840
doing at least a couple passes of mest 86 and playing games for a couple of

51
00:03:54,400 --> 00:04:00,280
hours to ensure that things are functioning correctly out of the box

52
00:03:58,439 --> 00:04:03,920
after all you wouldn't take a new car to the track and Tred to go 200 km an hour

53
00:04:02,640 --> 00:04:09,040
in it until you made sure it can stay in a straight line going 60 clicks right

54
00:04:06,280 --> 00:04:12,640
step two gather your software toolkit while I mentioned mest 86 already you're

55
00:04:10,959 --> 00:04:17,680
going to want a couple of other things in your bag of tricks for stress testing

56
00:04:15,200 --> 00:04:21,720
CPUs Z lets you see how your processor is running so you can verify your

57
00:04:19,160 --> 00:04:25,919
settings and Cort temp lets you monitor your CPU's temperatures in real time to

58
00:04:24,160 --> 00:04:30,320
see if they're getting out of hand if you want an all-in-one utility and a

59
00:04:27,880 --> 00:04:34,960
nice userfriendly package I to 6 4 gets a solid recommendation from us it's what

60
00:04:32,680 --> 00:04:40,639
we use and it includes monitoring stress testing and diagnostic stuff but it does

61
00:04:38,240 --> 00:04:46,680
cost money everything else I mentioned is free step three set aside the time to

62
00:04:44,240 --> 00:04:51,199
do it properly be prepared to have your system not be usable for a day or two if

63
00:04:49,280 --> 00:04:55,560
you want to correctly dial in an overclock I'm not saying it will take

64
00:04:53,320 --> 00:04:59,840
that long I'm just saying it can take that long especially if you're a real

65
00:04:57,479 --> 00:05:04,000
stickler about validation I've seen stress testing programs fail after even

66
00:05:01,720 --> 00:05:08,320
a full day of Burnin and my personal standard is that if it's not 100% stable

67
00:05:06,720 --> 00:05:13,320
I'd rather turn it down a little rather than risk losing valuable work and data

68
00:05:10,479 --> 00:05:19,199
so I typically validate for 24 hours or more step four the tour of the UEFI BIOS

69
00:05:17,360 --> 00:05:23,160
on most motherboards pressing delete will land you in the ufi BIOS if you're

70
00:05:21,560 --> 00:05:27,600
not sure about your motherboard consult the menual a Seuss drops you into a

71
00:05:25,199 --> 00:05:30,600
simplified ufi by default that gives you all the basic info you need like

72
00:05:28,880 --> 00:05:34,840
temperatures and lets you adjust your fan speeds change boot order and enable

73
00:05:32,280 --> 00:05:39,680
your memories XMP profiles but doesn't really allow for any serious tuning

74
00:05:36,360 --> 00:05:41,600
press F7 to get to advanced mode most

75
00:05:39,680 --> 00:05:45,160
modern motherboard bioses have a ton of features that we didn't have in the old

76
00:05:43,440 --> 00:05:48,440
days you can navigate through the menus manually or you can create your own

77
00:05:47,000 --> 00:05:51,639
favorites menu with the settings that you use most frequently you can make

78
00:05:50,120 --> 00:05:55,840
quick notes as you progress through your overclock and review them later you can

79
00:05:53,880 --> 00:05:59,319
save profiles for known good settings so it's easy to revert to something that

80
00:05:57,199 --> 00:06:03,800
works when you're done experimenting and you can even have the motherboard take

81
00:06:01,199 --> 00:06:06,440
care of overclocking for you on its own we're going to experiment with that

82
00:06:04,840 --> 00:06:10,280
feature later on to see how close it can get to the performance of our manual

83
00:06:07,880 --> 00:06:15,240
overclock now if you want a bit of a deeper rundown of every setting things

84
00:06:12,919 --> 00:06:19,479
actually haven't changed a lot since our last Haswell overclocking guide in this

85
00:06:17,840 --> 00:06:24,759
guide we're going to leave most of the dials on auto and explain only the ones

86
00:06:21,800 --> 00:06:28,720
that we're changing as we go let's jump into the AI tweaker heading where most

87
00:06:26,639 --> 00:06:32,440
of this stuff is found now most Enthusiast grade memory these days has

88
00:06:30,280 --> 00:06:37,720
an XMP profile and if you set this setting to XMP it will dial in into its

89
00:06:35,400 --> 00:06:41,840
optimal settings you can push memory past its rated speeds but because of how

90
00:06:40,240 --> 00:06:47,000
difficult memory instability is to diagnose I really don't recommend doing

91
00:06:44,599 --> 00:06:52,039
it unless you have a lot of patience moving on down the CPU core ratio is

92
00:06:49,840 --> 00:06:57,039
where most of the magic happens this ratio times the base clock locked at 100

93
00:06:54,880 --> 00:07:00,120
MHz for all intents and purposes is how the processor's final frequency is

94
00:06:59,080 --> 00:07:04,479
derived as for the settings here sync all cores

95
00:07:02,400 --> 00:07:08,840
is faster and easier to dial in because it runs every core at the same speed

96
00:07:06,319 --> 00:07:13,560
which is easy to stress test but setting up different maximum turbos depending on

97
00:07:11,199 --> 00:07:17,440
how many cores are active could yield slightly better results in dual or

98
00:07:15,720 --> 00:07:22,879
single threaded applications we're going to stick with sync all cores next up is

99
00:07:20,160 --> 00:07:27,759
the CPU core voltage increasing core voltage improve CPU stability at higher

100
00:07:25,319 --> 00:07:32,599
clock speeds but higher voltages are also the main reason that overclocking

101
00:07:30,039 --> 00:07:36,759
causes higher temperatures and a shorter lifespan for your processor now there

102
00:07:34,840 --> 00:07:41,160
are actually several ways to set CPU voltage we're going to use manual

103
00:07:38,879 --> 00:07:46,039
voltage the generally regarded as pretty safe voltage being 1.3 Volts for Haswell

104
00:07:43,080 --> 00:07:51,360
based CPUs to find our Max over clock then to save power we're going to switch

105
00:07:48,360 --> 00:07:53,080
to Adaptive later on adaptive gives us

106
00:07:51,360 --> 00:07:57,039
better power consumption characteristics when the computer is not working hard

107
00:07:55,039 --> 00:08:00,879
and ramps up whenever the CPU needs more juice but it's not good for stress test

108
00:07:59,680 --> 00:08:05,240
when you're actually validating the overclock because certain stability

109
00:08:03,319 --> 00:08:10,159
testing applications can cause voltage spikes that can hurt your CPU in

110
00:08:07,479 --> 00:08:13,400
adaptive mode so now that we're familiar with the settings that we'll be running

111
00:08:11,599 --> 00:08:17,800
it's time to overclock we're going to start by leaving our CPU at stock

112
00:08:15,080 --> 00:08:21,360
voltage so 1.25 volts this is different from Auto which will actually scale

113
00:08:19,759 --> 00:08:24,840
voltage as you increase your frequencies thanks to the same BIOS Wizardry that

114
00:08:23,560 --> 00:08:30,560
will automatically be handling all the other settings in here that we didn't cover then we're going to turn all of

115
00:08:28,199 --> 00:08:35,240
our cores multiplier up a little bit let's say to 44 which would give us a

116
00:08:32,399 --> 00:08:38,680
speed of 4.4 GHz actually equal to what turbo boost will do on its own but let's

117
00:08:36,800 --> 00:08:42,080
just see if it can do it all the time so now we press F10 to save our settings

118
00:08:40,240 --> 00:08:46,839
boot into Windows and do some stability testing if the CPU passes a short let's

119
00:08:44,839 --> 00:08:49,920
say 5 to 10 minute stress test and temperatures are within your comfort

120
00:08:48,360 --> 00:08:54,279
zone remember higher tempts equals shorter CPU lifespan then we boot back

121
00:08:51,959 --> 00:08:58,320
into the BIOS and push it some more if it fails then we add a bit more voltage

122
00:08:56,279 --> 00:09:02,519
and see if that makes it stable it's important to go through this process to

123
00:09:00,519 --> 00:09:07,160
find out where you're needing to crank up the voltage a lot for a very small

124
00:09:04,800 --> 00:09:11,200
CPU frequency return that's the way to find the balance between the longevity

125
00:09:09,079 --> 00:09:15,000
of your chip and the extra performance that you crave another thing to consider

126
00:09:13,600 --> 00:09:19,440
is the conditions in which you're overclocking is it optimal is it the

127
00:09:17,279 --> 00:09:23,399
worst case scenario an overclock that you set up in the winter might not work

128
00:09:21,519 --> 00:09:27,519
correctly in the summer so leave yourself some buffer room or save a

129
00:09:25,560 --> 00:09:31,160
couple of other profiles that work in case you need to grab one of them when

130
00:09:29,000 --> 00:09:35,440
the weather heats up another thing to consider if you're working on other more

131
00:09:33,640 --> 00:09:39,279
advanced settings within the BIOS let's say you want to do some tuning to the

132
00:09:36,800 --> 00:09:43,560
RAM timings is to throw another step into the routine not everything you

133
00:09:41,240 --> 00:09:47,240
tweak will have a positive result so run a short Benchmark rather than just a

134
00:09:45,440 --> 00:09:51,760
stability test to see if what you're doing is actually helping or hindering

135
00:09:49,880 --> 00:09:56,279
performance once you've dialed in your overclock using manual voltage switch

136
00:09:54,040 --> 00:10:00,560
over to Adaptive then use a real world stress test like cinebench to validate

137
00:09:58,480 --> 00:10:04,800
your load voltage I found that just doing the math and keying in the same

138
00:10:02,279 --> 00:10:08,160
number actually didn't work so I used AI Suite to make sure the voltages were

139
00:10:06,320 --> 00:10:12,399
right and even though the software voltage readouts are typically not very

140
00:10:10,000 --> 00:10:16,279
accurate the system was stable and my load temps were similar once I turned

141
00:10:14,399 --> 00:10:20,200
things up a little bit more so it seemed to work a digital multimeter would

142
00:10:18,240 --> 00:10:23,399
actually be preferable if your board has voltage checkpoints though that's a

143
00:10:21,880 --> 00:10:29,320
great feature for overclockers unfortunately not found on WS

144
00:10:25,880 --> 00:10:32,040
boards so following this methodology we

145
00:10:29,320 --> 00:10:38,200
we achieved a 4.8 GHz on our 4790k at 1.3 Vols with a load CPU temperature of

146
00:10:34,440 --> 00:10:43,079
around 65° and Rock Solid stability and

147
00:10:38,200 --> 00:10:46,560
4.7 GHz on our g3258 at 1365 volts with

148
00:10:43,079 --> 00:10:49,920
a load CPU temperature of 49 Dees I gave

149
00:10:46,560 --> 00:10:52,040
the Pentium about 065 volts more than

150
00:10:49,920 --> 00:10:56,320
the typical best practice setting for Haswell for a couple of reasons number

151
00:10:54,240 --> 00:11:01,600
one is that temperatures were still great since it's a dual core and doesn't

152
00:10:58,639 --> 00:11:06,560
output much and number two is that as a $75 chip I'm a little bit more willing

153
00:11:04,079 --> 00:11:10,000
to live on the wild side with it both of these results are going to turn into

154
00:11:07,959 --> 00:11:13,680
some significant real world performance improvements but by now you might be

155
00:11:12,040 --> 00:11:17,560
sitting there kind of going well lonus this is all fine and good but ain't

156
00:11:15,480 --> 00:11:22,680
nobody got time for that is there another way well actually there are two

157
00:11:20,440 --> 00:11:27,160
other ways that I alluded to before to overclock on an isus motherboard number

00:11:24,639 --> 00:11:31,040
one is to Simply navigate to the easy tuning wizard in the BIOS answer a short

159
00:11:29,720 --> 00:11:35,079
questions about your setup then let the board apply one of the pre-done profiles

160
00:11:32,800 --> 00:11:39,160
that asusa Engineers have cooked up this resulted in lower more conservative

161
00:11:37,279 --> 00:11:43,480
overclocks at higher temperatures for both of our chips temps were still

162
00:11:41,480 --> 00:11:49,560
reasonable at only a couple of more degrees on both CPUs but it's just plain

163
00:11:47,320 --> 00:11:55,320
not as good as a manual overclock the second alternative way is to use ausus

164
00:11:51,760 --> 00:11:57,200
AI Suite softwares five-way optimization

165
00:11:55,320 --> 00:12:02,000
feature to have the board overclock itself it actually goes through much the

166
00:11:59,920 --> 00:12:05,880
same increase speed until unstable then increase voltage until stable rinse and

167
00:12:03,560 --> 00:12:10,040
repeat process that we did except it does it completely on its own and it

168
00:12:07,880 --> 00:12:16,199
actually works reasonably well the automated system ended up 100 MHz slower

169
00:12:12,440 --> 00:12:19,160
on my 4790k and 100 MHz faster on my

170
00:12:16,199 --> 00:12:24,079
g3258 with the only issue being that in both cases it was applying More Voltage

171
00:12:21,880 --> 00:12:28,279
than I was really comfortable with and since I'd already tested the system and

172
00:12:26,079 --> 00:12:33,920
found it to be stable with less voltage it seems like as was overdoing it a bit

173
00:12:30,920 --> 00:12:35,519
in both cases not a huge deal if you

174
00:12:33,920 --> 00:12:38,800
just want a quick and dirty overclock since it can dial it in in about 10

175
00:12:37,160 --> 00:12:43,880
minutes and you don't even need to touch it and they were both stable it's just

176
00:12:40,800 --> 00:12:45,680
not the proper way to do things either

177
00:12:43,880 --> 00:12:48,959
and that pretty much wraps it up thanks for checking out this overclocking guide

178
00:12:47,279 --> 00:12:52,880
if this answered your questions then Happy overclocking if it didn't and you
