Ryzen Master is probably more accurate right now. NZXT is still having some issues tuning the temp readings on Zen 3 (but at least it can be detected now), but is working on it for a future update to CAM. My z63 is measuring a similar 10 degree difference from Ryzen Master too. Answer from Angelic_Jin on reddit.com

October 2, 2020 -

For my Ryzen 5 3600, I was actually able to push 4.6 GHz on all cores with 1.3125 volts as stated in Ryzen Master. So i would like to ask if the program is actually accurate?

Below is a snapshot of my Cinebench run

Hello, I got the 3900x yesterday, and I would like some info on the softwares we can trust.

  • Motherboard: Asus 570 TUF

  • Cooler: Noctua U12A

  • I have updated the bios, installed AMD Chipset drivers, and I am using the Ryzen balanced power plan.

  • Bios uses default settings, just the ram is clocked to 3200 with the automatic profile.

According to Ryzen Master, I have 35 degree celsius on Windows and 60 in Battlefield V. I have not tried any stress test, and I honestly don't care about them.

Using CPU-Z benchmark tool, the all core boost is 4.15, the single core boost is 4.55

My question is on the idle core clock, and the softwares we can trust.

According to Task Manager, HWInfo, HWMonitor, or CPU-Z, even with 1-3% CPU usage with just Chrome open, the CPU lingers around 3.5-3.8ghz, and sometimes goes past 4ghz.

Instead, at the same time Ryzen Master tells me that 8-9 cores are sleeping and that the Peak Speed of the active cores is below 1ghz most of the time. Peak core voltage is usually around 1.1-1.2.

Should I just rely on Ryzen Master and disregard the info provided by all the other tools? It is honestly strange that the results are so different. Also, I expected a lower voltage on Windows, but maybe I am wrong?

Instead, at the same time Ryzen Master tells me that 8-9 cores are sleeping and that the Peak Speed of the active cores is below 1ghz most of the time. Peak core voltage is usually around 1.1-1.2 Ryzen master iirc, shows "effective" clockspeeds now. HWINFO64 also shows and labels that as "effective clockspeed" "Effective frequency" tells you how much work the CPU actually did, not the actual frequency. If Ryzen Master tells you a core is running at 1Ghz, it doesn't mean the CPU run at 1Ghz at any time. It could be running 4Ghz at 25% time and 75% of time the core just goes to sleep. https://www.reddit.com/r/Amd/comments/cjcrv2/how_can_ryzen_master_show_clocks_up_and_down/evd8tqs/?context=3

Here's the thing. The core sleeps when it's not doing anything, it literally shuts off. Now, if you ask the core "HEY, what frequency you runnin at?", you'll wake the core up, it'll report the frequency after it wakes up, and then go back to sleep. So, most software either report that frequency (when you wake up the core by asking it what frequency it's running at) or they report the last known frequency before the core went to sleep. Ryzen Master takes a different approach. It shows a rolling average of frequencies over a second (1000 milliseconds). So if your core was at 4 GHz for 100 milliseconds, but sleeping for the rest 900 milliseconds, it'll report 400 MHz (4*100+0*900/1000). As for how does it know if the core is sleeping, I assume it's counting the program counter or some other counter in the CPU to first see if the core did anything, then if it sees an increase, it check the frequency.

Hello,

I don't really understand why people don't like Ryzen Master, is AMD such a awful developer ?

I'm new to AMD world (X870 Pro RS with 9700X), and I wasn't a crazy overclocker on the intel platform. But when I ears all the troubles made by the Asrock voltage and amperage choices, I just wonder why people don't use Ryzen Master to tweek the BIOS parameters, as it's certainly more accurate and respectfull of what AMD want to see in BIOS settings.

Of course, the first thing to do is to uninstall Ryzen Master if you already have installed it, clear CMOS, default settings, and reinstall Ryzen Master. Then you can try all the PBO and Memory tweek you like, with trying it first without writing in BIOS and then when you are OK with stability, push in BIOS.

the only thing I'm aware of is that Ryzen Master is too optimistic with the CO settings and you have to do your own stability test.

But wouldn't be a good start and a way to bypass strange Asrock choices ?

r/Amd - Ryzen Master Update Inaccurate?
August 1, 2019 -

Now apparently over at MSI_Gaming, someone mentioned not to use HWinfo as it does not display accurate temps and thus should use Ryzen Master.

Now my fan curves are set like

35 & 60c running at 65% 65c running at 80% 70c running at 100%

Now.. Ryzen Master is displaying 45-50c while Steam is downloading in the background. Now fan should run at 65% with this temp. However I hear the fan throttling up and down meaning its bumping to 80% then down to 65%.

Now.. Hwinfo however is showing my temps reaching fluctuating to 65-67 then down to 50s. The fans are throttling according to what HWinFo is showing.

So why is Ryzen Master showing different temps when my fan throttles to different % speed?

EDIT: Seen someone say Ryzen Master โ€œtweakedโ€ to display Average Temps. Kinda useless when youre trying to monitor current temp not average.

I just got the 9800x3d and got everything booted perfect and downloaded Ryzen Master and just enabled Expo. On restart I'm now stuck on 15 mobo error code(memory issues).

I've tried reseating each one, swapping them, used just one in the correct slot, tried using the incorrect slot with both one stick and two. It's still stuck on error 15.

Do I have to tear down my rig and pull the cmos battery from under the heat sink??? I don't exactly have extra ram sitting around to try.

March 13, 2024 - I confirm,almost lost my mind 2 years ago when i was building some pcs,updating the chipset drivers and installing ryzen master completely broke my windows installation and had to reinstall it from usb cause the pc would just black screen on startup then restart back in an infinite cycle. Apparently it has nothing to do with overclocking,the problem is the way ryzen master can corrupt important files randomly upon installation

Is Ryzen Master accurate? | Tom's Hardware Forum
December 9, 2017 - I have tried using cinebench and using ryzen master as my temp monitor and it still kicks to 70C, just for added info before i overclocked my stress tests temps only records 50C and I only overclocked my processor to 3.7 ... 50c is too low for an overclocked Ryzen under load (like when gaming or benchmarking) unless you are a room that is near freezing.

r/AMDHelp on Reddit: Ryzen Master vs Bios temp
January 6, 2021 -

Recently, I found out that I can use my Q Code read out screen on my motherboard to display the CPU temperature if no pressing issues are occurring. This has been very handy as I haven't been able to monitor my CPU without alt tabbing out of games and checking ryzen master when gaming. However, I have noticed some discrepancies between the two. At idle both temps are pretty close, within 1-5 degrees of one another at any given point. However, I wanted to test this under load and ran Cinebench20 and got a fairly large discrepancy. My motherboard was reporting temps of ~70 degrees where Ryzen Master was showing around ~80-83. I am curious which one of these readouts would be more accurate? If it is Ryzen Master, I am unsure if 80 degrees during cinebench is too high. If so, should I try to reseat my CPU?

r/Amd on Reddit: Most accurate software to measure temps for 3700x?
August 14, 2019 -

I have been trying to figure out the temps on my 3700x but that seems to be quite the task since every software I try gives different readings. I have tried Ryzen Master, HWInfo and HW Monitor. Before I try Speccy I thought I'd ask what software is the most accurate an reading temps.

The problem is that Ryzen Master report idle temps at 35-37, HWINfor says its 30-33 and HWMonitor says its 39-41. It gets even crazier under load. In Battlefield V RM says max temp at around 70-73, HWInfo ended on 65 and HWMonitor went all the way up to 80.

I'd like to think RM is the most accurate considering it comes from AMD but I dont like the software since I cant seem to get a log saying what max temp is and when alt tabbing the temp do change a few degrees so I have no chance to get the correct max temp. On the two others it says Max temp so I do not need to alt tab all the time trying to find where the cpu ends up. I have kind of ruled out HWMonitor since the case fans doesnt go up to 100% when HWMonitor report 80 degrees.

So anyone have any idea which software really is the most accurate?

And are there any way to get a log out of RM?
