Ryzen 5 3600 @4.5GHz, 1.425v

[lufusol]

Is this a decent overclock for my CPU?

Set to 4500 MHz and 1.425v in Ryzen Master, HWMonitor shows all cores at 4491MHz, CPU VDD reads steady at 1.400v while running Cinebench (10,408) and a max temp of 81°C

That's a lil hot and my fans get loud but it seems to be stable. 4.4GHz @ 1.3v knocks off 11 degrees (70°C), and 4.2 @ 1.175v runs quietly at just 61°C under load so I'll probably run it like that most of the time.

I have no idea what's typical for this chip, but I haven't tried pushing it any harder. Bwok, bwok bwok. Thanks for your feedback

While that's a good clock speed for Zen 2, and while 81C isn't awful for it, I'd recommend reading into if that is a safe, long term voltage. While some Zen 2 CPUs will go up to 1.4V to even 1.5V (my Ruzen 7 3700X does) on default behavior, this will be seen with low current (amperage). Doing it constantly under an all core load (high current) like that may be dangerous for it.

I appreciate your response and your caution, I just don't know about "dangerous" with voltage and temp both way within spec, maybe it will lose a couple years in longevity, totally acceptable, it's a budget cpu I bought to overclock.

What I HAVE read as dangerous is the initial false claims for the Zen2 (and resulting issues people caused themselves) with UNDERvolting (to the point of clock stretching)

FWIW I verified a performance increase with each clock increase, and verified there was no further performance increase with additional voltage at a given clock speed. So I know I'm not clock stretching.

What I'm hearing is it's a good overclock! Thanks :D

Edit: lol, keep reading, my hubris doesn't hold up 😂

I think it's too much voltage, it might be fine but you should keep it in the 1.3x range just to be more safe, these 7nm ryzen cpus are more sensitive to voltage, up to 1.5v in short bursts is fine for light work/gaming but for all core heavy stuff it always goes down to 1,25-1,30 range to keep the silicon healthy, doing heavy work with that voltage is not safe, you should use PBO instead, fine tune it with the right PPT,TDC,EDC limits and maybe add AutoOC value like +100/200mhz, this way it should boost in games just as much but a bit lower the more work you put on the cpu, at least you feed the silicon with healthy voltages, or just run it stock and you probably won't notice a difference in performance with that weak gpu.

1.35v is enough to do damage within a month, you will kill this CPU very quickly

Okay that's a fair point about the voltage, explained a little better than the previous guy who didn't like it, but you didn't need to make the comment or assumption about the relevance of "that weak gpu" - I just built this system. Have YOU tried to buy a gpu lately?? Who says I'm a gamer? This thread is about cpu overclocking. I tried AutoOC it was garbage. Maybe 2% difference. Cheers.

I'm not entirely in the know of every detail about Zen 2 CPUs. I personally don't overclock mine, as there's little point to with the way they work by default, and I overclocked my prior few platforms. It's just that, from what I understand of it, the "voltage limit" isn't a strict value, because there's other variables. Under a higher core count load, when a lot of current is drawn, the safe voltage limit is less than if it's under low current draw, from what I understand. I would personally not be pushing 1.4V through these under a heavy, all core load.

Ah yeah, I get what both of you are saying now, thank you.

I noticed the voltage requirement for stable frequency did start to get more demanding above 4.3GHz. Until then it was pretty much 25 millivolts per 50mhz increase

I'm happy to run it at stock most of the time and maybe switch to the 4.2GHz profile when I'm doing Ableton or rendering

...or gaming, if I can ever buy a card that isn't weak. I hope cryptominers get scabies.

That voltage will absolutely demolish your CPU at higher levels of current. It's not the voltage that damages the CPU, it's a combination of voltage and current. Stop this immediately, or irreversibly damage your CPU. I degraded my 3900X a bit with much less voltage. Stop.

Since Zen2, Ryzen processors rely heavily on the chip's health management (aka the Silicon Fitness/FIT) to manage voltage automatically in order to prevent potential damage to the chip at higher current draw because of how fine and sensitive the manufacturing process has made the CPUs. The lower the current, the higher the voltage, which is why you'll see your CPU reach 1.5v at idle or while browsing the internet, but at full current load (i.e. P95 small FFT testing), these CPUs can have the voltage cap out as low as 1.1~1.15v.

Any voltage that the FIT doesn't consistently allow in a particular level of current, that's higher than that voltage, is plainly hazardous to the processor and will damage it over time, which will drastically affect the CPU's ability to perform as well as it did when you first bought it.

These CPUs are best left to stock settings or PBO (with scalar untouched/set to 1X) because a manual OC disables/impedes the chip's health management. If you refuse to listen, it's your own damn fault if you wreck your CPU. Tons of users have ruined their 3600s by overclocking on even just 1.3v. 14 and 12nm Ryzen had a cap of around 1.3625v according to AMD, but there is no official safe voltage recommended by AMD for their 7nm chips because they can't recommend one. It differs from chip to chip and is decided by the FIT based on the load.

Leave it at stock and forget about it. You're not going to get worthwhile performance from overclocking a 7nm Ryzen processor because the risks are too high and it's a huge increase in power draw for usually only ~5% extra performance.

It's pointless overclocking that cpu. Just get a good cooler and let your cpu do the rest. No point in ruining your cpu and voiding your warranty. A 24-hour run of prime95 small will let you know if it's stable.
Still pointless. What you really should be doing is running in eco-mode to take advantage of the best features of your cpu. It will still be fast and powerful and whisper quiet.

[GOD RAYS ON ULTRA™]

Oh, and if you really want to overclock you go with intel, not amd. Intel is the enthusiast platform. amd is mainstream/value/efficiency.

Not untrue, but not completely true, either.

Zen 3 currently outperforms Intel in many areas, and likewise, Intel is close enough, but much cheaper, so in a way roles have somewhat reversed a bit. Enthusiasm isn't defined by financial status.

Also, even on Intel, overclocking is far less meaningful than it used to be, because modern CPUs are just much closer to their cielings than before. With AMD, it pretty much pushes itself much further to that limit, though. Intel may push itself less by default, I imagine, because their CPUs use more power.

So it'd be more true to simply say "overclocking is usually less meaningful than it once was, more so on AMD".

And very dangerous on TSMC 7nm and smaller. Anything more than 1.2v is very likely to not be good for most 7nm chips.

It's not that hard to cool those cpus down. Get it down to at least where it never peaks above 70-75*C and this will help in the long run.

Except it's going to degrade regardless of temperature because it's damage caused at high current and not by heat.

TSMC N7 can't take high voltage at high current. The best way to find a safe voltage for 7nm Ryzen is to see the lowest auto voltage while running a torture test like P95 small fft. Most chips are between 1 to 1.2v.

The number is set by the chip's health management, which changes voltage limits based on current. So, whatever you get in p95 small fft is the ideal maximum for a manual OC.

Anything higher brings a risk of degradation, which many users experienced after they ignored warnings.

People need to stop applying old OC logic to 7nm processors ffs.

Whoa doggy! You're passionate about saving my CPU. Well thank you.

Guys, I only benched the oc potential for one evening (with ryzen master) and I haven't run it like that again. It's been mostly at stock, I haven't committed any full-time OC settings in the BIOS yet.

But just to contradict one of your statements... Just so you know, on completely stock, running Cinebench R23 (all cores and threads absolutely pegged) it does 4092MHz on all cores while CPU VDD reports a steady 1.35v (reaching 72°C). I can do this all day and that's "under warranty" (pretending I haven't already voided mine)

So how could a manual OC of 4.35GHz at 1.25v a bad thing? Maybe this is usually true, but I just have REALLY great chip? Or maybe I'm still just really abusing it, but that doesn't explain the stock behavior in comparison to your cautions. Hmm.
