The Ryzen 5 3600 Discussion Thread

kayone · 12 Jul 2019 at 08:39

Having just moved from a great overclocking CPU in my R7 1700 I'm curious as to what people are achieving with their new R5 3600? I'm yet to have a proper go at mine.

What Motherboard?
What Volts?
Highest stable Clock Speed?
Temperature?

I've not had much chance to fiddle too in-depth but I got mine at 4.2 on all cores with 1.125 vcore. I started off much higher but constantly lowering it I managed to find what mine seems to like.
Memory timings have been odd though each time I change them one CCX goes back to stock clocks meaning half my cores get stuck at 3.6ghz.
Will play around tonight and attempt to figure out why.

No point overclocking, games run a 4.2Ghz and stuff like cinebench is at 4.1, max you could get is 4.3 but might require higher than average voltage.

TNA · 12 Jul 2019 at 10:38

How about underclocking? Anyone tried that with this cpu? Results?

The more I am reading the more I think this is the CPU that I should upgrade to. Will scratch the itch and I can upgrade again in 2 years time to the AM5 platform to the 5000 series with 16 cores as my long term build. By then they will hopefully be able to hit higher clock speeds as they are lacking that right now imo. Then the 3600 can go into partners rig.

RavenXXX2 · 12 Jul 2019 at 10:42

There is no way emodan is running at 1.125v. These chips require at least 1.35v for 4.2Ghz.

I'm blown away by the 3600 performance, highly recommend it and it will not bottleneck even a 2080ti so good for years to come.

Was just reading an article on this and how the 3000 series represents a shift in the market away from overclocking; Precision Boost 2 is getting pretty much all of the performance out of these chips (within reasonable vCore limits) at stock settings.

Interesting stuff. I've been questioning the value of overclocking for a while now TBH. Going back ten years or so, it was a relatively cheap way to get a nice performance boost. Whereas now it has become this entire industry designed to upsell people to better gear in order to deliver that "free" gain.

When the time comes that I need more performance, I'll see what I can get out of my 2600 with the gear I've got. Or more likely, I'll upgrade to a 3600 or 4600.

I think the second '1' is meant to be a '3' looking at his cpu-z validation

seems AGESA 1.0.0.3AB meant to fix 1-2 core boosting .

Temi_D · 12 Jul 2019 at 16:00

Doubt these have much headroom. Mine even runs hotter than I'd like. 75+ in IBT and 85+ in Prime 95.

Exactly my findings.

I'm on 1.0.0.1 (B450) and it already boosts to the advertised 4.2ghz. I was under the impression it is only a problem with the 3900X.

I wouldn't say at least. I reckon very good chips could do it in the 1.3-1.35v range, unless they've all been binned to the 3600X.

It's already known that better binned 3700X and 3900X don't require 1.35+ voltage at 4.2ghz. At 1.35+ they can do 4.3ghz.

*voltages are all at load

https://www.gamersnexus.net/hwreviews/3489-amd-ryzen-5-3600-cpu-review-benchmarks-vs-intel

Our 3600 silicon is much worse than our 3900X and 3700X silicon, so the overclock requires 1.43V to hold 4.3GHz all-core. This lands us at 90W down the EPS12V rails with all power limits manually disabled. This is the only chart that will contain the R7 and R9 data for our 3600 review, but briefly: The R7 3700X stock CPU consumes about 87W when stock and 103W when overclocked to 4.3GHz at 1.35V; note that our voltage required here goes down one full step from the 3600, but core count has gone up. This is a silicon quality advantage, and that carries to the 3900X. Our 3900X could hold 4.3GHz all-core, across all 12 cores, at just 1.34V.

Do old motherboards like B350 have precision boost 2?

I thought this was on the chip?

Yesi remember when a decent overclocking board was maybe 20-30 quid more than a normal value board, not like 130.

No. 300 series motherboards have Precision Boost and 400 series motherboards have Precision Boost 2.

chroniclard · 12 Jul 2019 at 19:29

If you dont mind losing a couple of hundred mhz of boost just try an all core clock with the lowest voltage you can, much cooler and barely lose any performance.

Yeah Prime really hammers mine too under AIO.. instantly upto 85c with Prime95 reporting from Ryzen Master, I hope it's incorrectly read from the bet BIOS I'm using from MSI..

I'm not sure that's true.

You might be referring to XFR2, however, that isn't used by the 3xxx chps.

3xxx chips use Precision Boost 2 + PBO.

edit:

This can be simply seen by the various comparisons done with B350 vs X570 when using a chip which doesn't overly load the VRMs on the cheaper boards e.g. R5 3600.

Jacky60 · 12 Jul 2019 at 21:44

Right now Zen2 and Overclocking don't belong in the same sentence. What you see advertised is rather more than you're ever likely to get. Maybe that will change but given the phenomenal overclocking headroom of the 1800X, 2700X I wouldn't hold your breath.

I think it's the correct reading. I've managed to get it down to 78 max in prime95 by using an offset of -70mV. I'm still getting the single thread boost of 4.2GHz and all core fluctuates between 4.05 - 4.15GHz and voltage between 1.3-1.36v . It's in the mid 60s when encoding so that'll do me for now.

kayone · 13 Jul 2019 at 06:54

I've tried adding an offset in BIOS, but my boost whilst running Cinebench puts the vCore at 1.375-1.4 @ 4075Ghz in Ryzen Master. Seems very high to me, albeit temp is only at 66c by the end of the multi-test.

edit: it has also taken 10c off my initial prime temp.

edit2: If I compare with cpu-z however this is showing 1.29-1.30 which seems more realistic.
