I have the GigaByte X570 AURUS XTREME motherboard and had until the beginning of this week a 3600X in it and now I have a 3950X. My experience - and this is not just with GigaByte mobos, but with other mobos as well - is that you have two choices, both of which are mutually exclusive. 1) You can configure your BIOS manually and NEVER use the Ryzen Master utility for anything 2) Configure your Vcore LLC (Load Line Calibration, in my case turbo, and SOC LLC, in my case high, and getting rid of the logo at boot. Don't configure anything else. After booting into Windows configure the system with Ryzen Master. For God's sakes don't try to configure the motherboard with the utility Easy Tune - your system will hate you for it. If you try to mix and match the two options you will be headed for a world of pain and frustration. The crazy thing is that even if you set the parameters exactly the same in both the BIOS and Ryzen Master, you will have nothing but problems. Now as always there are exceptions to the rule, and in my case there are two of them: A) When I wanted to overclock my RAM to MCLK and FCLK 1867 from 1800 I had to go into Settings and AMD Overclocking then, DDR and Infinity Fabric Freqencies/Timings portion of the BIOS and set the FCLK value to 1867 there. Ryzen Master will change the MCLK but not the FCLK if you are overclocking your RAM. B) With the 3950X being a 16 Core/32 Thread CPU, I don't need SMT for most of the things I do - especially gaming. By turning SMT Off you can take the max clock you achieved previously with SMT On and add 100 MHz clockspeed to each core. The only problem is that Ryzen Master will not actually change from SMT On to Off (or vice versa) as it does with other motherboards I have worked with, so I have to do it manually by going into Tweaker then Advanced CPU Settings and then set SMT Mode to Disabled. I made the mistake of listening to the advice of the Tech YouTubers and of the Tech Media and have found out, after a number of weeks of frustration, that as far as the Ryzen 3000 series of CPUs is concerned they haven't got a bloody clue. Also ALL motherboards will punt way too much voltage into the Ryzen 3000 series of CPUs. Even Ryzen Master on any of the profiles puts an amount of voltage into the CPUs that will damage them over a relatively short period of time (measured in months, not years. To this end, if you want to configure your CPU correctly, then, in Ryzen Master, create a Manual profile and under Voltage Control set the Peak Core(s) Voltage to 1. 3 Volts, and see how far you can clock it stably. When you have reached a stable clock at that, then you can try lowering the voltage in increments (in my case it was one increment to 1. 29375 Volts) and enjoy a system which will give you good performance, low temps and above all last a long time.

The old days when processors ran flat-out, so that a cheap Celeron set to the frequency that only the expensive Pentium (according to Intel) was supposed to run at would get it to operate about like a Pentium, have gone away. It isn't only that processors can throttle to avoid destruction or malfunction, as it once was; processors have to be designed to throttle at all times, because that has become the only possible way to keep temps manageable (and the power draw within specs, as in mobile devices) Processors have far more hardware resources (in order to increase instructions per cycle, packed more densely, than could possibly be fully on all the time and not overheat. All the AMD words (PBO, etc) are market-speak for some hardware implementation of how to shut down and throttle the execution hardware, but also avoid it when unnecessary. Intel and ARM have been doing likewise, of course, but they don't say much about what they are doing. I suppose it doesn't sound very good to say that your hardware is always operating at a fraction of its potential. The better the hardware, and the higher the price, the smaller the fraction. More processors per chip probably do better, if the program uses them, just because the heat is spread out more, keeping the temps down, and allowing each individual processor to operate more to its potential. (If only programs were written to take advantage of more processors)

Ryzen 5 3600, Asrock B450 ITX-AC. Stock config has a power ceiling that I'm able to hit in certain scenarios (Prime95 Small. PBO is able to raise these for a modest bump. Not many real-world workloads will hit this power ceiling though, and I don't know if this is particularly good for this tier of motherboard's VRMs. But I'm running into another problem. I have a freakin' 240 CLC on this thing that's able to keep my A10-7870k at 55 under the hardest loads I can give it. But I routinely encounter 75C during Prime95 Small, up to 80C, immediately, not accounting for loop arm up time on my CLC, and my motherboard's stock fan curves slam the fans and pump to full power. I've reapplied my thermal paste a few times, reseated the cooler, checked my fans, cleaned everything, I just don't know what I'm doing wrong to see such insanely high temperatures. The only other time I've seen CPU temps this high was when I undersized my cooler in an ill-fated attempt to cram said A10 into a tiny SFF box that really wasn't meant to hold a 95w part.

I bought a dell inspiron 5676 for 629 on amazon about a month ago with a ryzen 7 2700 and rx580 4gb model. the problem i have with it is that it doesnt boost to its rate 4. 1ghz on any core, it justs stays at 3350mhz on all cores and doesnt boost at all. ryzen master doesnt launch either it just says not responding every time i try to open it. i also looked at the bios and the cpu speed is 3200 mhz and it doesnt give me any options to change anything, not even the voltage. the problem isnt temperature because its 35C at idie and 47C when gaming. i just want to know if its the motherboard thats stopping me from getting my boost clock. ohh and on cpuid hardware monitor the min is 2600mhz and the max is around 3600mhz, but i never see anything higher then 3350mhz on msi afterburner. Dell Inspiron Gaming PC Desktop AMD Ryzen 7 2700 Processor, 16GB DRAM, 1TB HDD, AMD Radeon RX 580 4GB GDDR5 Graphics Card, Windows 10 64-bit, Blue LED, Model Number: i5676-A696Blu t

That warranty voidance thing doesn't sit well with me. How does it make sense that you loose your warranty when you use the same motherboard to get the maximum power and Amperage for a 3700X on that of the 3900X? Why is there no in between step that you say for a 65 TDP CPU that it will use the 95/110 TDP setttings. That should be perfectly responsible assuming that you use a proper motherboard for it (not some B350) and AMD could let you keep the warranty in that case. Now it is either a ridiculously low setting because of AMD its crazy 65 TDP rating for an X part or you go overboad and say: don't care about any of it at all. Maybe in practice it doesn't matter if every 3700X gets to that 4. 4 GHz boost without getting the amperage and voltage too high but regardless AMD could make that OC'ing more flexible. A TDP-setting would be a nice addition. Is it fair to say that TDP is just an indication for which class cooler you need?

5: 50 This is essentially wrong. PBO, through its current limits, allows you to configure away all power delivery limits (you can set all three variables to 1000 to make them irrelevant, if your MB is sufficiently provisioned with capable VRM's. That makes the only variable thermals, which means the better your cooling, the better your clock speeds. For example, a TR 2950X under water, with PBO, will hit 4. 1GHZ on all cores forever. Not saying that won't happen with a sufficiently good AIO, but an AIO is not real water cooling, and the quality of cooling varies considerably (i. e. sometimes no better than air, which all custom loops that aren't cheap Ali Express buys will be better than. Provided the motherboard doesn't fail on power delivery, PBO is equivalent to better cooling = better performance.

Obviously this videos oldish by now, but one of your last points about providing all of the performance out of the box simply isn't true. I haven't been able to actually OC my 3600x. Just couldn't find anything stable. But PBO and auto OC had me locked to 4. 1ghz max. Rated speeds are 3. 8ghz with a boost to 4. 4ghz. I was able to get to 4. 4ghz all core speed without much trouble. Like I mentioned, I can't get anythnig past that stable, but the fact that I couldn't even boost to the rated speeds bothered me. I'm using an x570 TUF. I'd love to see some really in depth ram OCing using ryzen master, or at least a video of it done on the x570 tuf since it's basically this generations b450 tomahawk max.

So basically it is a bunch of BS. My own tests confirm no benefits worth talking about or even poorer results. So I find leave it at stock to be best. So AMD markets as unlocked this should be false advertising although I know technically is not false. So another issue related to marketing is price, is it really cheaper than comparable Intel products? Yes and No! Cheaper if you already have a MB from last gen, but not really cheaper when you get an x570 board. I am fine with my 3700x system, but I do wish I had gone with 9900k. When compared a bundled 9900k system vs a 8core16t Ryzen system the price is not that different at least when the 9900 was on sale. I hope future AMD updates change all this.

I wonder if these numbers are just because of the great motherboards? I saw HUGE benefits in single and multi core scores, like 20% single and 16% multi core with PBO enabled on a B450 Steel Legend board with R5 3600. I also think I won the silacone lottery because I was able to get all core 4. 12 ghz stable 1. 3725 v with a CryoRig H7 cooler and under looped Cinebench R20 tests never broke 75c. I don t think AMD planned on the 3600 or the B450M being that good lol. That said I just left PBO in my system is super snappy and responsive, and it BARELY ever creeps over 60c with a budget board and cooler, and I m sure one of those cases you ripped to shreds for its airflow because it was 45 from Newegg

Thank you sooooooo much for this video! This compiles so much information that I needed, all into one place. I am exploring PBO vs. Precision Boost 2. 0 on my ASUS X570-E + AMD 3950X + 64GB DDR4 3733 (CL16. Much of what you said were precisely the type of questions that I had. Such as the options under the PBO tab that seemed to have nothing to do with PBO, haha. If I am boosting to 4. 5 GHz right now on my 3950X using a Corsair H110, do you think it would be possible that Precision Boost 2. 0 could boost me to 4. 7 GHz if I upgraded my cooling to a dedicated H2O rig? I know it comes down to the silicon, but I am just wondering, in general terms of thermals vs gains. Thanks again and keep it up!
