3600 4.6GHZ
3600 4.6GHZ
I know it sounds a little too clickbait, but I'm actually running 4.6, which is way above the usual 4.3 marks on most reviews. Can you check my picture and see if something looks wrong? Also, what products or tests can I use to really prove it works right, and what should I watch out for?
Oh. The long answer lol. You've got a Ryzen, not an Intel. They're totally different, don't work the same way, and you shouldn't expect them to behave the same way either. You're used to Intel, where their temps feel normal, they have overclocking (OC), and they boost up automatically for everything. Intel sets a ceiling and pushes the processor all the way there whenever it can. So if your base speed is 3.4GHz but turbo is 3.9GHz, then when you move the mouse or play games, it will hit that 3.9GHz limit and keep going until you reach 100°C. At that point, Intel turns down the power to save itself from overheating. But Ryzen can also get hot at 100°C too. They just don't want to do that ever, no matter what cooler you have attached to them. So their boost is all up or down depending on how cool things are. If temps and voltages allow, they'll go as high as possible on the minimum number of cores available.
Please don't use HWMonitor because it isn't very reliable for Ryzen chips. Instead, try using HWInfo (with just the sensors) along with a tool like Ryzen Master. That combination is known to be pretty accurate. 4.6GHz is actually not that hard to get; you can easily do that with PBO set to level 3 or 4. What is really hard though is getting stable PBO levels at 3 or 4 without needing lots of cooling and good VRM temperature control. You won't see those speeds on full load either, and neither will you see 1.1v and 4.6GHz staying steady across all cores. Most people only manage to get 4.2GHz or 4.3GHz at 1.3v or higher during Prime95 small FFT tests. According to the temps (which might be a bit off), you are probably just at idle load, which is totally different from being stable under full stress. You will almost certainly crash after just a few minutes of any stress test.
you were right, but I had some errors thinking something was wrong. now running version 4.3 and honestly, trying to make it stable at low voltage since that's how the system is set up. what are the safe limits for 24/7 operation on the 3600? my reason for wanting a manual overclock is because PBO spikes the cpu voltage, making temps go up and fans spin louder. this gets annoying, so i'm trying to avoid it by just going for a safe overclock instead. is it okay with occt using these settings or should i change the link https://ibb.co/60NbRmV?
Oh. The long answer lol. You have a Ryzen, not an Intel. They aren't the same, don't work the same, don't go about doing things the same way. And you are used to Intel, the way its temps are, it's OC, it's boosts. Intel sets a limit and automatically boosts to that limit for everything. So if the base speed is 3.4GHz, turbo is 3.9GHz then soon as you move the mouse, play a tune, punish the cpu with a stress test, it'll boost to 3.9GHz and stay there unless you hit @ 100°C, then it'll throttle back to save itself. Ryzen can also reach 100°C, they just do not want to, ever, no matter what cpu cooler you have. So their boost is variable. IF temps and voltages allow, they'll boost to max on as minimum amount of cores possible. If temps and/or voltages would put you at high temps, they'll back down a little, so you can maintain at least good performance and reasonable temps/voltages. Both Ryzen and Intel want to give best performance possible, Intel doesn't care how it does it, Ryzen tries to do it within the boundaries. At idle, Intel lowers voltages and speeds to all cores, but all cores remain active. So background tasks are split up between every core as needed. So you'll see idle of @ 30 and spikes to @ 50 in general as temp readers poll the hottest core. With Ryzen at idle, it shuts down all the cores totally, keeping just 1 active. This means the full load of all the background tasks is on 1 core, so idle temps read @ 40 - 60ish. With a load, like moving the mouse, both Intel and Ryzen bring all cores upto working speeds, Intel max turbo and Ryzen whatevers appropriate for the job. So Intel will see higher temps at low loads and Ryzen temps don't really budge from idle. Not until a sizable load. With pbo, you've made the boost more aggressive for those low-mid loads, so the boost is higher, hotter and the fans respond the same. Instead, adjust your fan curves, set minimum duty cycle a little higher and set the curve to not climb until 5°C higher than the spikes. So if pbo is bouncing 45-65, you'd set a low rise from 40-70 ending in @ 50-60% duty cycle and then a short rise from 70-75 with max fans at 75 °C. Also make sure you use Balanced power plan, not performance.
thanks for all the help so far, but I am not using PBO right now because I'm doing a manual run. I've been using Prime95 Small FTT mostly and it works great. Most of my heat/power tests are fine with me, there isn't anything wrong with the readings so far. It's going really well. Currently on a 25-minute prime run, I just don't want to risk degrading my CPU if I use PBO instead of manual settings. I know exactly what the limits are and I have an AMD Ryzen 7 2800X (AIO). My voltage is set to 1.265V https://ibb.co/x5PC145
Actually, it's the opposite. Ryzen Master and PBO control themselves and won't let dangerous amperages happen. This is exactly what is going on with Ryzens when people Overclock (OC). A Ryzen can handle up to 1.5 volts at very low current loads. It can handle up to 1.325 volts at high current loads. The difference comes down to just what counts as a "high current load." So overclockers are bumping the vcore up to 1.3 or 1.4 volts but forgetting that there is a shift in current needed to get that speed reached. They end up with an extreme current load after locking all cores at that boost level level. Honestly, even 1.3v is pushing your luck when you have a very high constant OC. But most people treat the Ryzen like it's an Intel. PBO will control the current, allow for only specific maximums but also allowing spike current. It'll also limit wattage used, thereby limiting voltage at higher current boost levels. It'll mean you may not hit a target speed as such, but the cpu will boost exactly what it needs to, and boost as much as it's able to on as many cores as required. And not exceed limits or temps. With PBO, you won't need to worry about stability. But just like any overclock, you will need to watch temps in order to get the best boost you can.
Ah, okay. So the best way is just to go with PBO and make sure my temperatures stay steady. Thanks!
The best way is just to run Ryzen with PBO off. It only gives a tiny boost to quick tests and adds heat, so I'd skip it unless testing specifically. With great CPU cooling and fast low latency 3600mhz RAM, you can lower the Intel frequency to 1800MHz and push the chip hard without worrying about damage from PBO or static overclocking. Let PB2 do what it needs to do and then be ready.
