ryzen 5600x looking to undervolt+keeping performance gains

[squallypo]

hi there, i recently got interested in this topic but im unsure how to proceed other than what ive done so far.

i have a ryzen 5600x with a gigabyte b550m aorus elite 1.0 rev
i have done pbo limits disabled, curve optimizer -30 on all cores and its been working fine 0 issues at all, but i live in a place where temps during the afternoon is not ideal (30+)
so i wanted to go further and undervolt /settings offset to the voltage of the cpu, but im unsure how to proceed with this bios ive seen videos but most of the people are using asus or msi so its hard to know where is the option to do this.
perhaps someone with experience could help me out.
im using f17 bios

thanks for your time.

I am playing with a 5600x currently with an aio cooler.

Perhaps thats what you need. You didnt provide temps.

During those hours on load it can get to 70/75c I'm using a hyper 212 black edition, I might get a thernalright phantom spirit Evo 120 or a ak620 digital version, but at the time being I do wanna try the undervolt section, or is it not advised for any reason ?

you're about 20c from max limit of 95c. Both of those coolers look good enough I would get the TR ps evo has 7 pipes vs 6 on ak620

I think you're pretty much out of luck with that, when I tried using an offset to undervolt my 5600 further it would just decrease the maximum frequency w/ PBO.

out of curiosity for my own purposes:

this is where i can set the value to undervolt, correct? cpu vcore was on auto, set it to normal because theres no other options
then changed dynamic vcore (dvid) from auto to -offset as you can see in the picture, just wanna make sure this is correct.

now if i can or not keep the same performance thats something im willing to accept if this helps with the temperatures that it can get during the hours i mentioned specially recently it has been rather bad in here.

in the end its gonna come down to whats available when i actually get to make the purchase, which is not now.
seems to be likely that ill be getting the ak620 for availability reasons rather than for what i want.

are you talking about pbo limits manual + CO? excuse my noobness.

his vrm will catch fire

yeah no thanks lol, i do have CO all cores on -30 and its been working like that for a year or so without a problem.
i have set the PBO limits to disabled to keep it under default.

I havent tried anything crazy yet with this only playing with ram speeds. im just amazed how this chip is so efficient even with smt off.

That offset voltage looks like the right one to me.

Though honestly I'd just disable PBO, with my 5600 the difference between PBO on/off (4.45/4.65GHz) is negligible for gaming with my 3060. Mainly because it's not really being used enough to actually run at 4.65GHz most of the time anyway.

+1 for some better cooling, but you might benefit from a reseat.
The 212 is HDT, so you need to fill in the gaps and then apply the TIM in small lines between them (not assuming anything here regarding your application, just a possibility).

I'm not sure what prices are like by you but here the 212 is no longer the greatest value proposition here in the US (IMO).
You can find coolers like the Thermalright PA-120 for a little over $30, and that punches in the Noctua NH-D15's weight class.

Oh I agree I wanna change the cooler and I will, what does hdt means ? Also just to point out, I recently reapplied thermal paste like 3 times because I wasn't liking the temps, then again recently it has been hot here so I'm guessing environmental temperature has its effects, I was even looking at application methods I ended up doing the x because the pea size didn't covered the whole cpu, using the mx-6.

HDT means the heat pipes make direct contact with the CPU so it's a different application process than usual.

The small gaps in between the copper need to get filled in (I've used latex gloves / my finger, but an applicator works too)
Then small lines go onto the copper heat pipes themselves, it's been a while but last time I did IIRC I kept the lines about from "please peal" to "warning" (not all the way out).

now this is something i would like to test, to set an example:

i apply pea size on the cpu.
then on the cpu cooler, apply some thermal paste lines from vertical or horizontal?
or by a lines you mean just to spread it around later? dont wanna be confused here and apply more than it requires.

 

[freeagent]

It won’t use all of that power, maybe 140w tops under one of the most insane loads possible. I run my 5600X at 200/140/180 +150 -30 and it is cock solid

well for the time being setting this "negative offset" on dynamic vcore to -0.072v seems to be good and keeps the performance well enough as well.
also i edited the pbo limits to manual and set the default incase my motherboard is doing something that it shoudlnt: ppt 76, tdc60, edc 90 had to install ryzen master to know which are the default values for this cpu.

You will achieve the best results with an HDT cooler using that method.
The lines should run parallel with the copper heat pipes (directly on them), the aluminum gaps between them should have a thin layer applied evenly as well (just the 3x gaps in the middle).

Like this ?

 

[Deleted member 229121]

That's slightly different, but honestly seems like way less of a pain in the rear compared to filling in the gaps and then going direct on the pipes
Give that a go, but you can try both and see which comes out on top

 

[squallypo]

just to seal the topic, by no means does setting an offset like i have above here, produces any harm to the cpu/motherboard, right?
other than that i think my questions are pretty much answered and im very grateful for everyone's time.

If you're only using negative core-offset it's just an undervolt, the only thing you have to worry about is keeping the CPU stable.
It's when you start tuning PBO that you will push the VRMs.

I'm actually keeping the pbo limit to default settings for the cpu manually added it myself just Incase, also curve optimizer with -30 all cores and the offset of the dynamic vcore to -0.102v which is more than I expected tbh.
If something is off what could I expect on the system ? Bsod, crashes ? Or something else ?

 

[Deleted member 229121]

With undervolts, system instability usually rears its head when idle.

My 5800X couldn't handle -30 CO (all-core) without random desktop crashes, so I had to dial it back.
Got luckier with the X3D thankfully and can keep -30, which is good because it's a much toastier chip by contrast.
