00:00:00,000 --> 00:00:06,060
if you've got an AMD processor or just thinking about buying one you might be a

2
00:00:04,319 --> 00:00:10,559
little confused by all the intricacies of team red specific overclocking and

3
00:00:08,639 --> 00:00:14,480
yes I know that there are options for one click quick and dirty overclocking

4
00:00:12,660 --> 00:00:18,660
but there are some ryzen specific idiosyncrasies that are super helpful to

5
00:00:17,039 --> 00:00:24,019
know about today we're going to be talking about Precision boost overdrive

6
00:00:20,939 --> 00:00:26,760
or PBO my favorite type of Sandwich

7
00:00:24,019 --> 00:00:31,320
specifically we're talking about pbo2 the version on Modern ryzen 5000 and

8
00:00:29,400 --> 00:00:36,180
7000 chips but we're just going to refer to it as PBO from here on out is that

9
00:00:34,140 --> 00:00:41,100
okay although it's often thought of as another one-click overclocking solution

10
00:00:38,340 --> 00:00:46,680
it turns out that PBO doesn't directly overclock your CPU which has been a

11
00:00:44,219 --> 00:00:52,079
source of confusion what PBO actually does is send more power to the processor

12
00:00:49,620 --> 00:00:57,420
which allows the CPU to sustain higher clock speeds for longer periods of time

13
00:00:54,840 --> 00:01:01,620
so if you turn PBO on but leave the rest of your settings on defaults you'll see

14
00:00:59,340 --> 00:01:05,760
the CPU spend more time hitting whatever the Boost speed is on the spec sheet

15
00:01:04,140 --> 00:01:10,320
simple enough but here's a recommendation for you the best way to

16
00:01:07,799 --> 00:01:14,939
ensure you do in fact have PBO turned on is to go into your BIOS and specifically

17
00:01:12,600 --> 00:01:20,220
look for the AMD overclocking section additionally although you can enable PBO

18
00:01:17,340 --> 00:01:25,140
through ryzen master in Windows ryzen Master can turn it back off upon reboot

19
00:01:22,500 --> 00:01:28,979
depending on how it's configured so yeah just enable it through the actual AMD

20
00:01:27,240 --> 00:01:33,299
settings in your BIOS and save yourself some headaches so once you've got it

21
00:01:31,140 --> 00:01:38,460
turned on another optional but cool thing you can try is undervolting the

22
00:01:35,640 --> 00:01:43,140
chip through PBO although this sounds counterintuitive as the point of PBO is

23
00:01:40,799 --> 00:01:48,180
to give the CPU more power many Verizon CPUs can actually achieve the same level

24
00:01:45,360 --> 00:01:55,920
of performance with less power also meaning less noise and heat and money

25
00:01:52,880 --> 00:01:58,320
yeah this could be especially useful for

26
00:01:55,920 --> 00:02:03,299
the new 7000 series which runs hotter and consumes more power than the 5000

27
00:02:00,840 --> 00:02:08,700
series so if you want to undervolt just set the curve Optimizer to negative and

28
00:02:05,820 --> 00:02:13,020
enter a value between 1 and 30 in the magnitude field the larger the number

29
00:02:10,619 --> 00:02:16,980
the greater the undervolt but you won't want to go too aggressive or your system

30
00:02:14,819 --> 00:02:20,819
will become unstable try some different values to see which works best with your

31
00:02:18,840 --> 00:02:25,080
specific chip and hopefully your PC doesn't disintegrate

32
00:02:22,500 --> 00:02:29,580
so you know how to use PBO but how do you combine it with an actual overclock

33
00:02:26,819 --> 00:02:32,879
to maximize your performance we'll tell you right after we thank freshbooks for

41
00:02:56,879 --> 00:03:03,480
actually turning your clock speeds up with PBO isn't too hard although you can

42
00:03:01,440 --> 00:03:07,680
just select the auto overclocking option in ryzen master and Windows and call it

43
00:03:05,640 --> 00:03:12,180
a day you can get better results in the BIOS with minimal effort in that same

44
00:03:10,140 --> 00:03:15,659
AMD overclocking section in your BIOS that we mentioned earlier look for a

45
00:03:13,980 --> 00:03:20,580
setting that says something like boost clock override from there you can enter

46
00:03:18,120 --> 00:03:25,440
in a value in megahertz that represents how far past the maximum boost clock

47
00:03:23,159 --> 00:03:30,360
listed on the box you want to push your processor starting small and adjusting

48
00:03:27,840 --> 00:03:34,319
in roughly 25 megahertz increments is a good way to find a stable speed that

49
00:03:32,280 --> 00:03:38,519
maximizes performance without pushing the system too hard now this might not

50
00:03:36,300 --> 00:03:42,959
sound super different from traditional overclocking but doing it through PBO is

51
00:03:41,519 --> 00:03:47,580
actually a bit safer since you're raising power limits without manually

52
00:03:45,120 --> 00:03:52,920
overvolting meaning that there's no risk of frying your poor CPU why do you

53
00:03:51,000 --> 00:03:56,879
torture it not to mention that PBO actually uses a smart algorithm that'll

54
00:03:55,379 --> 00:04:00,599
keep you from completely throwing caution to the wind of course you'll

55
00:03:58,739 --> 00:04:03,900
still want to appropriately stress test your system to make sure your PBO

56
00:04:02,159 --> 00:04:08,099
overclock is stable and your computer won't crash while gaming watching the

57
00:04:06,360 --> 00:04:12,360
final of the Bachelor or in the middle of a crucial job interview unless you're

58
00:04:10,379 --> 00:04:16,979
applying for a job here at LMG in which case I can assure you we'll have tons of

59
00:04:14,459 --> 00:04:20,280
sympathy for a failed overclock oh we might even give you bonus points hey
