Ryzen Owners Zen Garden

[BlindZenDriver]

So I build this new machine and was curious to see how many cores would reach the 4200 Mhz max boost clock of my Ryzen 3600, only to find that from what I can see they all do and they do so simultaneously.

I thought the concept was the CPU would have 3600 Mhz as the all core base and that it would then clock individual cores up to the 4200 Mhz, but that it would be just a couple of cores doing so and it would then be alternating between them to spread the heat. Have I misunderstood something? Somehow gotten hold of a very well performing Ryzen 3600 or?

I have done nothing in terms of tweaking any settings, the only exception is I have made the motherboard use the XMP memory info, so it runs the ram at 3600 Mhz CL 16 which is also the specs given for the ram I bought.

I am curious - if all cores can run 4200 Mhz out of the box could I then perhaps change the max boost clock to something higher and get more performance, even without having to change voltage settings?


Also a somewhat related question, using OpenHardwareMonitor it only shows the RPM of 4 of the 6 fans connected to the motherboard and also only 7 of the 8 fan controls (two of which have no fans connected). Using MSI Dragon Center I can see all the fan RPM's.

Any idea on how to fix that in OpenHardwareMonitor?

Don't use openhardwaremon...

Use hwinfo64, and look at effective clock for the real clockspeed.

Got a new build going and trying to get some stability happening.

3900x is at 4.1 @1.2v, which doesn't sound too great just yet. I'm quite confident that I'm going to need some help in getting the most out of this.

Interesting - I shall give it a good look.

Part of my reson to use OpenHardwareMonitor is a tool called FanControl that uses an API that is OpenHardwareMonitor. I have not tried it yet due to the issue with not all fans shown, but supposedly FanControl will let you setup fan profiles that use several sensors as triggers ie. one can have fans rpms be the result of fx. motherboard and/or CPU temperatures.

Yeah another vote here for HWiinfo64, i left mine on auto and just watched which core(s) was the lowest which was about 4.29 all core so i just set mine too 4.2 and then tweaked the voltages.

I ended up at 1.275 @ 4.2.

I ended up at 1.275 @ 4.2.

That actually is starting to sound really good. I'm a little surprised by how much these chips vary. Seems I got some computational errors at my settings so dropped it back to 4@1.15, which worked before. Testing that now.


Anybody using a 3900x on the stock cooler?

Not surprising when your trying to overclock two CCD dies, and the quality of the cores on one does vary in the top clockspeed it comfortably runs at.

Just be careful your not pushing it to hard with the voltage. The all cores during a heavy load amperage is what kills.

Don't they have per CCD overclocking so they can be done independent of each other?

Yes, in Ryzen Master or the BIOS.

Sounds like good info, thanks. As you say, I don't want to kill it with voltage, but I do plan to run it under WCG so that means maxed all the time, maybe with an occasional rest. At the time I'm more limited by temps, but once the new cooler comes in, it should allow for some additional pushing of the CPU.

It’s not the voltage that kills but the total measured amperage of all cores firing away. Hence the scaling back of voltage, and clockspeed as the cores pick up load in the default/auto factory state.

For most users, fixed Vcore between 1.2-1.3V and under 80C should allow for a long, fulfilling life. But as you're crunching all the time, probably shoot for 1.25V or below and cool it with any respectable 120mm tower equal to or better than a Dark Rock Slim or U12S. Should allow for 4.1GHz all core at the very least, which is more or less the maximum all-core you'd get from default Precision Boost. I'm sure you won't be hankering for a tiny bit more benchmark score anyways

 

[biffzinker]

My early attempts when I first got the 3600 at a all core overclock of 4.2 GHz at a higher Vcore may been what killed my Ryzen 5 3600. After that I noticed I wasn’t able to use any of PBO predefined options. Before that it would work with PBO.

My goal is to keep voltages low and even the core clocks low to be safe. The 1600x has been solid and stable with a slight overclock, which was kept moderate since it too crunched for a long time. Once the 360 AIO comes in, I'd love to shoot for a 4.2 OC, so we'll see how it goes in the next few days.

Outside of hwinfo and cpuz, all other monitoring apps create more problems than they are worth with respect to Ryzen cpus. As for fan control, use the bios? You have a Unify, it should have great fan control.

Thanks for that link. I've encountered what appears to be that very issue, so it was a nice read to better understand what's going on.

Interestingly my new Ryzen 7 3800X is overclocking itself slightly for single thread load another 25-50 MHz above 4.5 GHz.
PBO is disabled so XFR2 is doing the overclock? With all cores loaded it starts out at 4.275 GHz then slowly drops back on clock speed, lowest I seen was 4.175 GHz.
Temperature was just under 70°C, seems this Hyper 212 Black Edition is holding it back?

Sounds like you've got a very promising chip there. R20 @ 4.2+ stock all core only being 70C under load with that cooler seems like the chip isn't calling for much voltage at all.

Yeah, I would call that a good sample, possibly golden!

<SNIP>

Thank you for the info - more to consider than I expected

Now on fans. Unfortunately hwinfo also doesn't show all the fans, so same issue there as with OpenHardwareMonitor - I think I will stick with having configured my 3 case fans identically and I therefore can with some degree of certainty can expect them to behave the same (although I prefer control than just going by expectation). I can monitor them with the MSI Dragon Center that is just rather cumbersome + from your info on how tools should monitor the Ryzen CPU's it also may come with other issues.

The Unity does have essentially the same control as one also have in Dragon Center which is good, but I do like the idea of having the fans being controlled by more than one metric. Only that is then just FanControl that supposedly offer that, so a no go atm since it uses OpenHardwareMonitor API.

Btw. As for the CPU cores and how their speed is being reported by HWInfo. What I can see is that all six cores happily will do 4200 Mhz, but giving Cinebench a go what happens then is looks like they alternate between 4125 and 4200 Mhz so the all cores 4200 Mhz is just briefly and more like all the cores alternate a bit only so fast it isn't really picked up.

I shall leave it as is for now and then perhaps get back to tweaking when I have more time to be systematic about it.

replaced the thermal paste on my ryzen 1400 system with the wraith prism
she just likes the 60C mark, and slooooooowly builds up heat no matter the paste used, stock, generic CM crap, or kryonaut.

Might just be the fan profile the board uses, not sure.

 

[biffzinker]

The Wraith Prism cooler that came bundled with my 3800X has the roughest machine finish I’ve seen on any air cooler. It looks all most as bad as the older Hyper 212 I had with a deep gouge in one of the center heat pipes.

 

[Mussels]

i definitely see some gap lines between the heatpipes, its such a nice cooler overall tho :\

Both get made in the same place ?. Pretty sure i heard they were.

Mine was a bit ruff around the edges too, gotta watch out for those fakes too.
