How does ryzen overclock?
previously I used Intel Haswell (4670K) with a multiplier of 45x and Vcore at 1.25v. The Vcore changes depending on usage, but the multiplier remains fixed at 45x. I’m unsure which settings cause the Vcore to vary while the multiplier stays constant. For example, browsing keeps Vcore around 0.7v yet the overclocking still works. On the other hand, when I set a multiplier of 45x with Vcore at 1.32v and left other settings auto, it still maintained 1.32v. It seems there might be an option I missed to stabilize the Vcore without changing the multiplier. I’m trying to reduce voltage below 1.3v while keeping a stable multiplier, and I’m curious if there’s a specific setting or feature that addresses this.
Ryzen overclocking is most effective through Ryzen Master, not the BIOS. This means I can't address the vcore topic here. PBO is my preferred option, though single-core overclocks are possible but limited in control. For context, my 3600x reaches around 4.3 GHz with about 1.320 peak core voltage.
baseclock runs at 3.6Ghz while my boost is 4.1Ghz. I think 4.5Ghz allcore is possible with just 1.3v, especially with good multi and single at R20. The pbo only hits 2400, but my 4.5 reaches 2900 and single at R20 does too, around 400 something. Just let the CPU handle it without tweaking Ryzen Master. My friend's 3600 also reached 4.5/4/6 at 1.35v allcore stable, and 4.2Ghz at 1.1v.
That’s not what Jayz said, I believe it comes from the 3900X OC video I watched Anthony too. I’m a bit confused, so maybe I’ll try the Ryzen Master later. This all-core BIOS version runs faster than what PBO can do, but I’m not sure about the high static Vcore during idle.
I've checked my wife's BIOS at 4.2ghz all-core at 1.25V. My is running 4.4ghz all-core at 1.352V medium LLC. Those are the voltage settings. I've stopped using Ryzen Master and just tested RAM anyway. The readings from HWInfo look lower—about 1.344 at idle. As @piratemonkey mentioned, Ryzen Master helps fine-tune things before setting it in BIOS. I'm not sure about lowering idle voltage, but core VID drops and cooler performance at idle compared to auto settings. Still, I don't have enough knowledge to confirm.
When you manually over-volt, the cpu will be set and should stay where user applied it. If it fluctuates beyond that, check windows power settings. Should stay constant with High performance setting. This is normal. When you see the Multiplier stay 45x and the Cpu v-core drop to 0.7v, that is also normal. The cpu can accomplish this when a lot of cores/threads (transistors in general) are gated or parked. perfectly normal, can sometimes cause instability, generally when running stock power states, the frequency multiplier will lower in accordance to that given p-state voltage. The Cpu can do any work in a p-state. The c-states are idle voltage variations and typically no work load is being done. The threads that enter a c-state are then eligible for being parked. When SMT is enabled, these threads are generally parked to save power thus decreasing the power demand but continue to remain at high frequency. A great test is to set defaults and run a stress test. watch it for a little bit. where it settles is based off the algorithm based on temps. If your manual overclock creates more heat than the stock cpu, then you then start increasing the degradation of the processor. Increasing the voltage beyond it's max all core boost at given frequency and x temperature, it'll boost to it's max. As mentioned before, turn on PBO, but even that won't get you past the thermal restrictions. Here is when I stop to think if I should give advice to OC when there's not a great deal to be gained honestly. Also, if some see that in Ryzen Master say EDC is in the red often, click game mode and then increase the threshold. This may help with boosting when in default settings. Hope this helps some of you. Not sure about that. Check for this part number instead. These are B-Die. https://www.neweggbusiness.com/product/p...20-232-437
I was searching for a C3 state in Ryzen, but Intel’s C3 state (Intel) doesn’t lower the voltage when idle or with low usage. The Ryzen Master (RMU) doesn’t work for me, and I always have to manually set it in BIOS. It crashes every time I try to adjust RMU, even when the BIOS defaults to mine’s settings. This is what I need—my Ryzen should behave like it does on my Ci5 4670K (4.5GHz, C3 enabled). How can I get that same behavior? Just let the CPU run alone but boost the memory instead. I already know from the ThrottleBurner that my RAM specs are correct.
I'm not sure if voltage changes with clock speeds like in auto, but I do understand that cores still shut down and stop using power. Monitoring confirms this. Yuck, no. PBO is for those who don't understand tech or who are okay with higher temps and lower performance.
