PBO for cpu?

[Mando772004]

So tomorrow im getting a new cooler corsair h100i pro for my ryzen 5 3600 which runs fairly hot. anyways i enabled pbo from my bios for now but is there anything else i should do like something with voltage cuz i heard i think i should lower voltage of something for more performance on cooler cpu's which i think my cpu will run cool cuz im also getting a new case with better airflow. way better airflow actually. what else should i do in the bios?

I've never heard that a cooler CPU will run better with lower voltage. What you probably heard was that lowering the voltage makes the CPU run cooler, and thermal throttle less.

Unless you're gonna go really deep into the weeds, PBO will do a better job of overclocking than you would manually. Just max out the power limits (there are three IIRC) and the scalar, and let it do its job

when i get the cooler supposedly it should auto oc my cpu to the max it can go which i think a r5 3600 can go up to 4.3ghz so if it does is there any other step i should do after that or just game?

there was an option called PBO scalar u mean this?

Yes. It basically defines how aggressive the auto OC is

Follow @Yebi's advice and max the power (not voltage), and let it do it's thing. That is, unless you want to try some manual tweaking!

alright count me in  supposedly my cooling will be good i mean 2 200m front fans 2 120mm top fans and 1 rear fan and the cpu is liquid cooled by a h100i pro so i think i can run at 4.3ghz fine at gaming temps of maybe 55-70

ok so i never did anything with the voltage. its default for now. what ur saying is i enable PBO and PBO scalar at max and thats pretty much it. also i have the options enabled i dont think there is a "max option"

Yes, my understanding is that ryzen 3000 does a great job on it's own, although I was foolish enough to get stuck on intel 9th gen, so I haven't tested it for myself.

alright thanks mate. i will finally be able to game on good temps!

To be more specific, the power limits are PPT, TDC, and EDC. You can use Ryzen Master to check if you're hitting them:

 

If any of these go red under load, you should increase the max number in BIOS. Normally that shouldn't be an issue, I think they get maxed automatically when you enable PBO

what max number exactly? im sorry i really am not very good with computers but you mean which numbers in bios or in ryzen master and how do i exactly change them?

It will depend on the BIOS. The general idea would be to find those acronyms in there and set them to something like 999 (it won't actually let you go that high, but it should roll back to the highest allowed number). But first of all I'd suggest to see if that is even an issue, you might not need to change anything

im testing a cpu heavy game ac origins i will tell u if i see red in any of those

ok so it did go to red like 2 or 3 times but it stays in red for a second or two and goes away. is this ok? also i dont have good cooling tomorrow i will though

Might be a better idea to run something like Cinebench R20 (it's free in the windows app store) - it will consistently hit your CPU to 100% and you won't have the trouble of trying to look at Ryzen Master while running something fullscreen. Also, you might want to wait unitl tommorow for that, because even if you're not hitting the limits with your current cooler, the new one might change that

ok one more thing. in the ryzen master it says my ram latency is 22!!! thats terrible. i have ballistix sport LT 3000mhz ram i OCed it to 3200 i think the normal is CL16 why is too high?

ok i tried and it is always at red  what do i do now?

Did you OC the ram manually? Generally speaking, the most hassle-free way is to enable the XMP (sometimes called DOCP on AMD) mode in BIOS. That should automatically set the frequancy and timings to what it says on the RAM's box. If you overclocked RAM to a higher frequency that it is rated for, it is possible that it can't handle normal timings with that frequency

turns out i oced manually but didnt change the timings. i did it again and in cpu z its running at 3200mhz and in ryzen master its at cas latency 16!! thank god i fixed it.
