Trying to oc R5 3600

[YouKnowZampe]

Hello,

I am trying to OC my r5 3600 (with msi b450 tomahawk max) with manual PBO but I have some issues.
I have gotten it to run stable before at 4.2ghz 1.3v but from nowhere it's unstable during stress tests and 4.1ghz does not seem better.

I use 42x multiplier and 1.275-1.3v. According to Hwmonitor and Ryzen master it runs at the set voltage at a constant.

These are my PBO settings:
PBO: Advanced
PBO limits: manual
PPT: 120w
TDC: 85A
EDC: 135A
PBO scalar: manual
Scalar 1x
Max cpu boost clock override: auto
Platfrom thermal throttle: auto
CPU core control: auto
SMT control: auto
LN2: mode 2: auto
NUMA nodes per socket: auto
LCLK dpm: auto
LCLK dpm enchanced PCIe detection: auto

Any help is very appreciated!

May I ask why you're using 42x multiplier? the 3600 should be able to boost to 4.2Ghz out of box, or after simply enabling PBO and no other tweak.

Because when im using only standard pbo it boosts to over 1.4v constantly.

Resell and get a 5600 or 5700x3d (prefferably off aliexpress or atleast used since new pricing is complete bullshit), if it only does 4.2 at 1.3v you have an older sample that simply doesnt clock very high so yeah youll see some real gains when you upgrade

yea an upgrade is far away for me at this stage. So i want to get the most out of my r5 3600 rn until i can get my hands on AM5

I mean, I'm not sure if 1.4v is bad,

 

have you researched if 1.4v on 3600 is bad?

 

I've checked Google and some people say 1.4v idle voltage is okay on 3600, did it 1.4v during load too?

The issues:

When i thought i had a "stable" oc @4.2 1.3v it worked fine for some time. Until I tried a aida64 and cinebench r23 again. Cinebench causes BSOD and aida says hardware failure. 

Of what i have found 1.4v at a constant is bad for the cpu. Which i got with only pbo enabled without any manual tweaking.

And it's 1.4v with everything else on auto?

 

Also, what about BIOS? Is it updated to the latest one that supports 3600? (I doubt tomahawk would drop support on newest version but you never know)

Yes it was 24/7 ≈1.43v before I set a static at ≈1.3v.

 

i updated to the latest bios 5min ago hope it will help. Idk which settings to use. Did not touch the pbo settings this time. Only 42x and 1.275v

 

edit: cinebench still crashes.

well, the cinebench could be crashing because the CPU could actually need 1.4v, and you're trying to run it at lower voltage, but if it crashes lower voltage, it's possibly the reason why it's running at 1.4v stock

You generally want to avoid 1.4V on 7nm.

 

If your sample can't achieve the desirable clock speed, just don't do it.

Just run 4ghz man, it’s 5 percent perf 

don’t waste ur time for 200 MHz

LLC medium, -30mv offset, scalar 2x or 3x, 130 PPT, keep it cool and just let it do it's thing. Not ever CPU is going to clock the same as every other CPU. A slightly slower but stable CPU is better than an unstable or burnt out one. Also keep an eye on SOC voltage, don't let it run too high.

I got it to run at 4.2ghz 1.3v for some time and from nowhere it’s not stable. Kinda there I’m stuck. Imma try more voltage

Seems stable with the settings you gave. Thank you! However it’s slower as you said. If I where to push this closer to 4.2ghz (4ghz now with pbo) how would I do? Multiplier or something in PBO settings?

Give it some more wattage, watch vdroop under load and adjust LLC and/or scalar to keep voltage up at stable levels under load, but watch out for instability when changing clockspeeds up and down when voltage goes up and down, it can over or undershoot and cause crashes or damage to the CPU. It'll do the best it can do, you can try to force it higher but it may simply not be capable of more.
