1 00:00:00,000 --> 00:00:04,840 If you've got an AMD processor, or just thinking about buying one, you might be a little confused 2 00:00:04,840 --> 00:00:08,440 by all the intricacies of team red specific overclocking. 3 00:00:08,440 --> 00:00:12,720 And yes, I know that there are options for one-click, quick and dirty overclocking, but 4 00:00:12,720 --> 00:00:17,600 there are some Ryzen-specific idiosyncrasies that are super helpful to know about. 5 00:00:17,600 --> 00:00:23,440 Today, we're going to be talking about Precision Boost Overdrive, or PBO, my favorite type of 6 00:00:23,440 --> 00:00:30,520 sandwich. Specifically, we're talking about PBO2, the version on modern Ryzen 5000 and 7000 chips, 7 00:00:30,520 --> 00:00:33,760 but we're just going to refer to it as PBO from here on out. 8 00:00:33,760 --> 00:00:38,880 Is that okay? Although it's often thought of as another one-click overclocking solution, it turns 9 00:00:38,880 --> 00:00:45,560 out that PBO doesn't directly overclock your CPU, which has been a source of confusion. 10 00:00:45,560 --> 00:00:51,400 What PBO actually does is send more power to the processor, which allows the CPU to sustain 11 00:00:51,400 --> 00:00:55,040 higher clock speeds for longer periods of time. 12 00:00:55,040 --> 00:00:59,160 So if you turn PBO on, but leave the rest of your settings on defaults, you'll see 13 00:00:59,160 --> 00:01:04,400 the CPU spend more time hitting whatever the boost speed is on the spec sheet. 14 00:01:04,400 --> 00:01:11,720 Simple enough, but here's a recommendation for you. The best way to ensure you do, in fact, have PBO turned on is to go into your BIOS and 15 00:01:11,720 --> 00:01:15,320 specifically look for the AMD overclocking section. 16 00:01:15,320 --> 00:01:20,320 Additionally, although you can enable PBO through Ryzen Master in Windows, Ryzen Master 17 00:01:20,400 --> 00:01:24,200 can turn it back off upon reboot, depending on how it's configured. 18 00:01:24,200 --> 00:01:29,000 So yeah, just enable it through the actual AMD settings in your BIOS and save yourself 19 00:01:29,000 --> 00:01:35,320 some headaches. So once you've got it turned on, another optional but cool thing you can try is undervolting 20 00:01:35,320 --> 00:01:42,800 the chip through PBO. Although this sounds counterintuitive as the point of PBO is to give the CPU more power, 21 00:01:42,800 --> 00:01:48,000 many Ryzen CPUs can actually achieve the same level of performance with less power, also 22 00:01:48,000 --> 00:01:52,520 meaning less noise and heat and money. 23 00:01:52,520 --> 00:01:58,880 Yeah. This could be especially useful for the new 7000 series, which runs hotter and consumes 24 00:01:58,880 --> 00:02:06,400 more power than the 5000 series. So if you want to undervolt, just set the curve optimizer to negative and enter a value 25 00:02:06,400 --> 00:02:09,800 between 1 and 30 in the magnitude field. 26 00:02:09,800 --> 00:02:16,480 The larger the number, the greater the undervolt. But you won't want to go too aggressive or your system will become unstable. 27 00:02:16,480 --> 00:02:20,280 Try some different values to see which works best with your specific chip and hopefully 28 00:02:20,280 --> 00:02:27,920 your PC doesn't disintegrate. So you know how to use PBO, but how do you combine it with an actual overclock to maximize 29 00:02:27,920 --> 00:02:32,920 your performance? Actually turning your clock speeds up with PBO isn't too hard. 30 00:02:32,920 --> 00:02:37,400 Although you can just select the auto overclocking option in Ryzen Master and Windows and call 31 00:02:37,400 --> 00:02:41,640 it a day, you can get better results in the BIOS with minimal effort. 32 00:02:41,640 --> 00:02:45,800 In that same AMD overclocking section in your BIOS that we mentioned earlier, look for a 33 00:02:45,840 --> 00:02:49,160 setting that says something like boost clock override. 34 00:02:49,160 --> 00:02:54,640 From there, you can enter in a value in megahertz that represents how far past the maximum 35 00:02:54,640 --> 00:02:58,560 boost clock listed on the box you want to push your processor. 36 00:02:58,560 --> 00:03:02,920 Starting small and adjusting in roughly 25 megahertz increments is a good way to find 37 00:03:02,920 --> 00:03:07,720 a stable speed that maximizes performance without pushing the system too hard. 38 00:03:07,720 --> 00:03:12,160 Now this might not sound super different from traditional overclocking, but doing it through 39 00:03:12,160 --> 00:03:19,000 PBO is actually a bit safer. Because you're raising power limits without manually overvolting, meaning that there's 40 00:03:19,000 --> 00:03:22,440 no risk of frying your poor CPU. 41 00:03:22,440 --> 00:03:28,480 Why do you torture it? Not to mention that PBO actually uses a smart algorithm that'll keep you from completely 42 00:03:28,480 --> 00:03:33,840 throwing caution to the wind. Of course, you'll still want to appropriately stress test your system to make sure your 43 00:03:33,840 --> 00:03:38,600 PBO overclock is stable and your computer won't crash while gaming, watching the final 44 00:03:38,600 --> 00:03:42,120 of The Bachelor, or in the middle of a crucial job interview. 45 00:03:42,120 --> 00:03:45,680 Unless you're applying for a job here at LMG, in which case, I can assure you, we'll 46 00:03:45,680 --> 00:03:48,760 have tons of sympathy for a failed overclock. 47 00:03:48,760 --> 00:03:52,240 We might even give you bonus points.
