How does ryzen overclock?

[ayazam]

the last time i overclock is with intel haswell (4670k), where i lock the multiplier @45x and set the vcore @1.25v,
but the vcore fluctuate at how much usage, but the multiplier stays @45x
i forgot what settings i do that make em fluctuate...

example: when just browsing vcore stays @0.7v~ still the multiplier stays @45x

 

does overclocking ryzen cpus work like that? where you set Xv and Xmultiplier, but the vcore fluctuate
or it stays at static vcore?

i tried OCing a 3500, by setting the multiplier 45x, vcore 1.32v, and leave the rest at auto
even when indling it still stays 1.32v, or is there any option that i missed?
i do intent to lower the voltage below 1.3v, with any stable multiplier...

motherboard: B450-A Pro MAX
RAM: 2x8GB SniperX 3600Mhz C19 (B-Die samsung if thats even matter)

thanks~

Try using PBO instead of forcing all core multipler. Doing a all core overclock will often hurt performance as the peak clock is lower as you can't hit max boost on all cores.

Ryzen overclocking is best done in Ryzen master, and not the BIOS. Because of this I can't answer the vcore question. PBO is what I would recommend, though you can always try doing single core overclocks. But they aren't the best, as you don't have a lot of control as you might think. For reference, my 3600x can do 4.3 ghz at ~1.320 peak core voltage.

so... baseclock is 3.6Ghz and my rated boostclock is 4.1Ghz,

i could easily do 4.5Ghz allcore with just 1.3v, with better multi and single at R20

Just turn on PBO and be done with it.

so the answer is "no, just let the cpu do the calculation"

with just pbo, r20 multi only reached 2400, where my allcore 4.5 reached 2900
and the single r20 too, with only 400something where the 4.5 reached 515

im just doin what jayz2c do tho, do it in bios, not bothering the ryzen master

also for reference, my friend's 3600 hit 4.5/4/6 1.35v allcore stable
and 4.2Ghz at 1.1v something

I didn't know Jay said that. I followed the advice that Anthony gave in the ryzen oc guide on LTT, which is to use Ryzen master. It's also faster to stress test it, as you don't need to restart.

Yeah, but PBO is a zero effort solution. You just tick the box.

thats no fun

jayz said it, i think its on the 3900X oc video

i did watch the anthony too, but im confused might try to do at the ryzen master later on,

since this allcore-bios oc-ing is faster than what pbo can do, but i cant handle the high static vcore at idling

I have my wife's 3600 at 4.2ghz all core at 1.25V.

 

Mine is at 4.4ghz all core at 1.352V medium LLC.

 

Those are bios voltages. I got tired of turning on ryzen master and was in there for RAM anyway. Read voltages on HWInfo read lower. 1.344 for me at idle. Like @piratemonkey said, Ryzen Master is a good testing tool. I used it to dial in my OC before committing it to bios.

 

As far as lowering voltage at idle etc, I'm not sure. It seems to, though. Core VID drops, and I run cooler at idle vs auto settings. But I honestly don't know enough about it to be sure.

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.

yeah, i was looking a c3 state-like option in ryzen, c3 state (intel) lowering vcore while idle/low usage

ryzen master (RMU) just doesnt work with me,

i always dial it in BIOS, it crashes whenever i tried to dial it in RMU even when i let the BIOS at default state

mine were ryzen balance setting in power option

this what i want my ryzen to do, that only happen with my Ci5 4670k 4.5Ghz 1.25v (c3 state enabled)

how can i make my ryzen do this too?

 

so just leave my cpu alone, but gained the memory...

Just enable PBO!

I don't know if voltage fluctuates based on clock speeds like in auto, but I do know that cores still park and stop drawing power. According to monitoring anyway.

Yuck, no. PBO is for the tech illiterate or lazy people that don't mind higher temps and worse performance.

Typhoon burner  isn't always correct. 

Look for your memory in the B die list. (Google for the list, I'm on mobile)

 

Try a program called QuickCpu.  You will be able to change the boost and frequency scaler on the fly and also have control of core parking and other features the program has for tweaking the power plan.
