3600 4.6GHZ
3600 4.6GHZ
Sorry about the somewhat attention-grabbing title, but it seems I’m running version 4.6 now. How is this possible since most reviews are around 4.3? Can you check my picture and confirm anything looks off? Also, what tools should I use to test properly and what should I watch for? https://ibb.co/c60xGb5
You're using a Ryzen processor instead of an Intel one. These two architectures behave quite differently. Intel maintains a fixed limit and automatically adjusts performance accordingly; for example, if the base speed is 3.4GHz and boost reaches 3.9GHz, it keeps that speed until you hit extreme temperatures. Once the CPU reaches around 100°C, it will throttle to protect itself.
Ryzen, on the other hand, can also reach high temperatures, but they don't aim to do so. Their performance adjustments are more variable, aiming for maximum efficiency with as few cores as possible when conditions allow.
That said, achieving 4.6GHz is straightforward and can be accomplished with PBO level 3 or 4. The challenge lies in securing a reliable PBO level 3 or 4 that offers significant cooling capacity and precise VRM temperature regulation. This stability isn't consistently present at full load outputs. Additionally, maintaining 1.1V and 4.6GHz across all cores remains unreliable, with most systems only reaching 4.2-4.3GHz under light Prime95 FFT loads. Based on the reported temperatures (though they may vary), you're likely operating at idle conditions rather than stable full-load performance. Stress tests often lead to crashes within minutes due to these inconsistencies.
ah you're right, i was mistaken about the issue. now i'm working on version 4.3 and focusing on stability at low voltage. what are the safe 24/7 limits for the 3600? my main reason for wanting a manual overclock is that pbo increases the cpu voltage, which raises temperatures and causes fans to spin faster. it's frustrating, so i'm trying to avoid this by opting for a stable 24/7 overclock.
is it okay to continue using occt with the current settings, or should i adjust them?
You're using a Ryzen processor instead of an Intel one. These two have different characteristics—don't function identically, and they operate differently. You're accustomed to Intel's behavior, where temperatures are controlled and boosts happen automatically up to a certain point. With Ryzen, things can vary more; it can also reach high temperatures, especially with certain cooling solutions. Their performance adjustments are less predictable.
If temperature and voltage conditions permit, Ryzen will aim for maximum speed using as few cores as needed. If overheating is a risk, it will reduce its output slightly to protect itself.
Both Ryzen and Intel strive for optimal performance, but they handle things differently. At idle, Intel adjusts voltages and speeds across all cores, keeping background tasks active but spreading the load. You’ll notice idle performance around 30% and spikes up to 50%, depending on which core is hot. With Ryzen at idle, it powers down most cores except one, resulting in lower idle temps (around 40–60°C). Under load, both systems ramp up all cores, but Intel typically reaches higher temperatures initially, while Ryzen maintains more stable temps.
Using PBO can make boosts more aggressive for mid-range tasks, increasing heat and fan speed. To manage this, tweak your fan curves, raise the minimum duty cycle slightly, and avoid steep climbs until the temperature jumps 5°C above the peak. Also, opt for a balanced power plan rather than performance mode.
Thanks for all the assistance thus far, but I'm not relying on PBO at the moment. I'm doing this manually. I've used a Prime 95 small FTT, and most heat/power tests show everything is fine so far—currently after 25 minutes of prime run. I just don't want to risk degrading my CPU by using PBO; I prefer being manual so I can understand the limits. My system has a 280mm AIO with a VCore of 1.265.
Actually, the opposite is true. Ryzen master and pbo manage themselves and won’t let unsafe voltages occur. This is what’s been occurring with the Ryzens and OC.
A Ryzen can cope with up to 1.5v under very light loads. It can sustain up to 1.325v when under heavy loads. The difference lies in the type of load being applied. Overclockers often raise the vcore to 1.3-1.4v without realizing they’re shifting to a higher current for the same speed. This results in an excessive current instead of the desired performance.
Most users still treat the Ryzen similarly to Intel processors.
PBO controls current, sets specific limits, and permits spikes in current. It also restricts power usage, which in turn caps voltage at higher boost levels.
With pbo, stability concerns disappear. However, as with any overclock, monitoring temperatures is essential to achieve optimal performance.
The optimal configuration is to run Ryzen without PBO...it only slightly improves short tests and increases heat, so it's better to skip bench-marking. With strong cooling and fast RAM at 3600mhz, you can set the frequency to 1800 and push the chip to its limit without risking damage from PBO or static overclocking...let PB2 handle the rest and you'll be fine.
