be nice if overclocking your pc were a little more straightforward i mean sure

4
00:00:12,320 --> 00:00:19,439
there are those automatic one-click solutions that can give a quick and

5
00:00:16,480 --> 00:00:22,640
dirty boost to your CPU but if you want to do it yourself

6
00:00:21,199 --> 00:00:27,279
you end up looking at all these confusing options in your UEFI BIOS

7
00:00:25,439 --> 00:00:32,239
instead of just a dial that you can turn to make the pc go faster and one thing

8
00:00:29,840 --> 00:00:37,600
that's easy to get confused by is the base clock and something called the CPU

9
00:00:34,640 --> 00:00:42,239
multiplier which together determine your CPU speed but what the heck are these

10
00:00:40,239 --> 00:00:47,120
things and why is it that they are separated out instead of just having one

11
00:00:45,040 --> 00:00:52,480
field where you punch in your desired CPU frequency it's a great question

12
00:00:49,760 --> 00:00:57,440
because even many enthusiasts are only familiar with overclocking with the

13
00:00:54,399 --> 00:01:00,320
multiplier and i get why the easiest way

14
00:00:57,440 --> 00:01:04,000
to adjust your CPU speed is to ignore everything else and bump up the

15
00:01:02,239 --> 00:01:08,320
multiplier adding voltage when it becomes unstable this approach does have

16
00:01:06,400 --> 00:01:13,840
some drawbacks though unless you're running AMD you will need to buy an

17
00:01:10,320 --> 00:01:15,840
unlocked k or x series processor and on

18
00:01:13,840 --> 00:01:19,920
both the blue and red team you'll need to buy a supported motherboard

19
00:01:17,680 --> 00:01:25,360
furthermore multiplier overclocking doesn't offer very fine control so if

20
00:01:22,720 --> 00:01:29,680
your system is let's say stable at 4.5 gigahertz but then crashes immediately

21
00:01:28,000 --> 00:01:33,560
at 4.6 who's to say that it might not have been

22
00:01:31,520 --> 00:01:38,799
also stable at 4.57 you could be leaving performance on

23
00:01:36,240 --> 00:01:45,439
the table with this method so now let's move on to the base clock so as it turns

24
00:01:41,840 --> 00:01:47,439
out your CPU GPU and RAM are not the

25
00:01:45,439 --> 00:01:53,040
only things inside your system that have a speed rated in megahertz and the base

26
00:01:50,399 --> 00:01:58,000
clock's job is to keep your pc's components in sync with each other so

27
00:01:56,240 --> 00:02:01,119
the base clock is provided by your chipset and you can learn more about

28
00:01:59,280 --> 00:02:05,840
chipsets up here but what you need to know for now is that the chipset

29
00:02:03,360 --> 00:02:11,039
basically serves as a kind of coordinator between your CPU and your

30
00:02:08,319 --> 00:02:15,920
other components and this base clock will tend to be much lower than the

31
00:02:13,680 --> 00:02:21,840
rated speeds of your processor and your memory a common default base clock is

32
00:02:18,560 --> 00:02:24,640
just a hundred megahertz but while that

33
00:02:21,840 --> 00:02:29,760
might be adequate for some hypothetical low speed controller or something it

34
00:02:26,879 --> 00:02:36,160
would be incredibly slow for a modern CPU so that is why your processor uses a

35
00:02:33,840 --> 00:02:42,319
multiplier that allows it to run multiple cycles for every one system

36
00:02:39,440 --> 00:02:44,959
cycle provided by your base clock it's really hard it's like you know this

37
00:02:44,000 --> 00:02:51,680
whole thing so if you have a processor that's rated for 3.5 gigahertz what's happening is

38
00:02:49,360 --> 00:02:57,120
that by default your system is probably running a 100 megahertz base clock with

39
00:02:54,000 --> 00:02:59,599
a 35 times multiplier so this base clock

40
00:02:57,120 --> 00:03:03,440
times multiplier paradigm lets your CPU match up with the rest of your computer

41
00:03:01,519 --> 00:03:08,239
while still allowing it to run at a high speed and even though many cpus actually

42
00:03:06,080 --> 00:03:12,480
have a high tolerance for overclocking even further

43
00:03:09,440 --> 00:03:15,440
many other components such as your pci

44
00:03:12,480 --> 00:03:20,800
express lanes or your SATA controller cannot deal well with running out of

45
00:03:18,480 --> 00:03:25,840
spec that means that adjusting your base clock by more than a tiny amount like a

46
00:03:23,120 --> 00:03:30,159
couple percent can often cause stability issues because it connects to so many

47
00:03:28,080 --> 00:03:35,599
different components and instability in just one of them can bring down your

48
00:03:32,080 --> 00:03:37,680
system fun fact in many cases base clock

49
00:03:35,599 --> 00:03:42,560
overclocking can lead to much worse types of instability where instead of a

50
00:03:40,000 --> 00:03:47,040
blue screen you end up corrupting your os or even losing a bunch of data so

51
00:03:44,799 --> 00:03:52,159
with that in mind then what's the point of being able to change the base clock

52
00:03:48,720 --> 00:03:54,159
at all well some cpus and motherboards

53
00:03:52,159 --> 00:03:58,840
are more tolerant of base clock adjustments than others and some

54
00:03:56,640 --> 00:04:03,920
processors even support what are called straps these are base clock values

55
00:04:01,439 --> 00:04:09,120
significantly above the default that might be stable enough and can be useful

56
00:04:06,959 --> 00:04:12,879
not just for boosting your CPU's speed but also that of your memory and

57
00:04:10,480 --> 00:04:16,880
sometimes your GPU while the speed of other components will remain unaffected

58
00:04:15,200 --> 00:04:21,040
so you may want to look up what straps your particular platform can support

59
00:04:19,519 --> 00:04:26,720
and even if you don't end up using a strap that's much higher than the default speed adjusting the base clock

60
00:04:24,639 --> 00:04:31,040
can still be useful if you just want to squeeze every last megahertz out of your

61
00:04:28,960 --> 00:04:34,639
hardware and hit a clock speed that's in between two multiplier settings it

62
00:04:33,199 --> 00:04:38,000
really depends on what parts you specifically have so

63
00:04:36,240 --> 00:04:42,240
don't be afraid of some trial and error that is as long as there's no important

64
00:04:39,919 --> 00:04:46,639
data on your machine just remember to keep your expectations and possibly your

65
00:04:44,720 --> 00:04:50,720
CPU speeds reasonable

66
00:04:48,479 --> 00:04:55,360
speaking of reasonable this segue isn't great but by my standards it's pretty
