Ryzen 3600 Overclocking

So I'm pretty new to overclocking, and I know there isn't a lot of headroom for Zen2 overclocking, but I thought I'd give it a go.

At 1.4V I was able to get my all core clock speed stable at 4200MHz which I was quite pleased with. I've backed off the voltage to the recommended safe level at 1.325V and I'm stable at 4150MHz all core.

The respective Cinebench R20 results for each are:
4.2Ghz - 3802
4.15Ghz - 3725
3.6Ghz (stock configuration) - 3502

Does anyone have any results of their own to compare these to?

If anyone's got any advice (apart from don't bother overclocking), or suggestions of other informative benchmarks I could do then I'd be all ears.
 
3800 with 4.2ghz is spot on. That's the best you will get.

Try PBO overclocking for a comparison.

PBO boosts to 4.05 and gives me a score of 3631.

That's also about right. However, with AutoOC (Clock Override +200mhz) you should be able to get more than 4.05ghz. Should also be able to get 4.3ghz or more on single threaded loads.

Do I have to enable AutoOC wiith Ryzen Master or can that be done via the Bios? I can't see an option for it anywhere near the PBO settings...

You have to go into advanced PBO settings and use clock override. Also depends on your board and BIOS as to whether its properly set up.

And I can do that in conjunction with a manual overclock? Or do I just set the clock speed to Auto and enable PBO and AutoOC?
 
Right well I think I've done that and its still only boosting to 4074:

What's really weird is that when idle the clock speeds are up at around 4200MHz but as soon as it's under load it jumps down to 4074. I assume this is some kind of thermal throttling? Doesn't seem right.

You want to increase PBO limits from auto.

There should be a motherboard limit level to select.

For best results need to keep temps below 70C (light loads should be easier to keep under 70C). By the time you hit 80C you've lost any additional benefit.

Hmm no that doesn't seem to do anything, still throttles back to 4049.

Using the new bios from yesterday?

If so, I don't know why you aren't getting anything more. There is variability in chips, but with no power limits and low temperatures you should see single cores go up to 4.4ghz. All core loads should be 4.2+ghz when lightly loaded.

I have an Asrock B450 board and I get that with a 3600, but only with their latest bios which came out less than a week ago.
 
It's strange that most people seem to be able to run their R5 3600s at 4.2 GHz all-core no problem. Definitely no point spending extra on the R5 3600X.

I've not updated to the new Bios yet. Quite a few people are reporting that their system has become unstable so I think I'll just wait. I'm not that desperate to get PBO working right this minute that I'd risk it.
 
So it seems my problem was having my RAM clock speed set too high. I've set it to just use an XMP profile now and cores are boosting up to 4374MHz. However, my performance under extreme load is still nowhere near as high as a manual overclock - my Cinebench score with this setup is 3561 and still only boosting up to 4049MHz. I guess the answer is that using Cinebench isn't a real-world scenario so I'm best to use PBO to boost performance of individual cores as required?
 
Depends if you feel you will be loading all cores often. If so it might be better to have your speed fixed at a known stable 4.2ghz.

We are talking such small margins anyway.
