Question CPU high voltage on auto.

[wizacss]

Hello,

I recently noticed that my 3200G, while gaming, even on not so heavy games, reaches 1.5v core voltage, and accordingly the temps go up too, even reaching 80-85 on heavier games, almost reaching 90 while benchmarking.

Everything in the BIOS is on auto, except for a little oc on the iGPU (1650mhz at 1.2v).
My mobo is a B450 Gaming Max msi, the CPU cooler is the AMD stock one, except for the thermal paste.

I read on some forums that the 3200G shouldn't go higher that 1.4v, so I'm kinda confused why the mobo pushes it higher.
I have to mention that on idle the voltage is around 1, pretty stable, temps around 40c.

I recently updated the chipset and the bios version, basically everything's up to date, the windows power plan is on AMD ryzen balanced.
My CPU-fan runs 55% under 55c, 77% on 65c and 100% on 75c

Thanks in advance!

have you checked it with ryzen master and see the value there?

Actually, I only used ryzen master to test if the iGPU oc was stable, and then just unistalled it since I didn't need it.

whoa that's a high voltage for auto oc.. try follow this step by step in order (read till end):

• Disconnect from internet and close any background apps.
• Uninstall every gpu driver using DDU (clean and do not restart).
• Uninstall all the processors (is a must, should be 4 on yours since it's 4 threads, also when it asks for restart, click on no and keep uninstalling all processors) on device manager like this:
  
  
  
  
  
• Uninstall AMD Chipset Software in control panel (if there is none, skip it.)
  
  
• restart the pc to bios, disable AMD fTPM and secure boot (if it's enabled by default), save and exit, go to bios again, flash to the latest bios (version 7B86vHG1 with agesa 1.2.0.7), go to bios after finished updating, then load default or optimized settings, disable CSM, then save and exit. If you cant boot with CSM disabled, then just enable it.
  
  (OPTIONAL) enable Above 4G Decoding and Resizable bar option (these 2 options wont be available unless CSM is disabled
  
  
• boot up to windows and install the latest Chipset driver (should be ver 4.06.xx), then reboot. after that check in Control Panel > Uninstall a Program > AMD Chipset Software and see if its already ver 4.06.xx that's installed.
  
  
• Install the latest radeon driver 22.7.1, and then connect to internet.
  
  *do this all offline until reboot after installing chipset driver, also you may reboot to bios after all of this to set the XMP (and previous settings you did). Download needed files (highlighted word) before doing step 1, do the step by orders.
  
  
• Run cmd as admin, then do chkdsk /x /f /r, after that do sfc /scannow
  
  
• And check windows update if there is any and install them (except optional update).
  
  
• Make sure the psu connected to the gpu is 1 pcie cable per 1 slot (use main cable, not the branches/split) like this:

1.526V for SVi2 core voltage... Yah, I tend to think that's a high voltage too. This is a 3200G, so based on Zen 1 architecture for the CPU cores...something to keep in mind.

I'd suggest staying with HWInfo64, it's by far the better tool for monitoring all Ryzen CPU's and AM4 motherboards. Ryzenmaster's good for performance/competition overclocking, not 24/7 useage. The service is even been a bit of a problem for many when the app itself isn't running. You did well uninstallng it.

I'd say try lowering Vcore voltage settings in BIOS, get it well below 1.45V max, 1.425 preferably, for the SVI2 Vcore voltage when in Windows with light useage. Use Offset adjustments to do so and check for stability. Once under 1.425V (preferred), if it doesn't stay stable at the frequency it's OC'd to you'll have to lower that till it's stable.

Once you have the SVI2 max voltage with no processing load under 1.45V (1.425V preferably) check it again under heavy workload (something like Cinebench). It should then be under 1.37V, under 1.35V preferably. If not, lower clocks (and voltage) again.

The recommended OC voltage range for any Zen 1 CPU is 1.425V light load (temps <70C), 1.38V max heavy load (temps 90C+). Zen 1 is Summit Ridge for the CPU's...the APU's based on Zen 1 are doubtless going to be very similar.

https://www.reddit.com/r/overclocking/wiki/cpu/amd/#wiki_am4

Please note there is terribly little overclocking headroom in any Zen CPU without raising voltage dangerously high and that's especially so for the Zen 1 APUs (3200/3400 G's). If you're trying to improve performance for gaming, you're much better off overclocking only the iGPU... and especially memory... anyway.

I'm definitely going to try that out, by the way I only overclocked the iGPU, no overclocks on the CPU.

wow...this reminds me of the early BIOS's on my GB AB350m and Ryzen 1700. They were over-volting like crazy then, everyone asking if it's OK, nobody knowing for sure. It took several rev's before GB figured out how to dial in safe default presets...or maybe cared enough to even try.

Added...so making sure both your motherboard BIOS and chipset drivers are up-to-date may be a very good idea.

Yes, first of all I'm going to try to update the BIOS, then see if something changes.

Do you have any recommendations for offsets to start with? I don't really have much knowledge about overclocking in general.

Trying this out right now before making any voltage adjustments, I'll let you know if anything changes, I'm currently updating the bios.

tell all the things you have done later 😀

 

[wizacss]

tell all the things you have done later 😀

I did everything apart from these things: disable AMD fTPM and secure boot and CSM.

Just finished, trying Cinebench, core voltage is stable at 1.34v with a maximum of 1.377v and an average of 1.343v
This is without XMP on and without iGPU overclock, I'll try to turn on XMP first, re-do Cinebench, same thing for the iGPU oc.

 

[wizacss]

Okay I think I know what's the problem here.
Everything was working fine till I opened the OC part in the bios by accepting the agreement.
Before this was done, CPU on Cinebench max clock was around 3670.
When I OC'ed the iGPU, the CPU on Cinebench could go up to 3900mhz, and the core voltage could still go up to 1.5v.
I think that by accepting the agreement it "unlocks" the CPU, the problem is that I think it tries to automatically overclock the CPU, but it's a pretty unstable oc, making voltage go up to 1.5v.

This is just a theory, but I noticed that till I touched the oc part, everything was working fine and the voltages were stable.

EDIT: Just flashed the BIOS, voltage is stable at 1.34v.

So yeah, that was the problem, when you touch the oc part in the BIOS it just automatically unlocks the CPU and tries to OC it automatically.

AHHHH...I wonder if you're seeing this because of Radeon Settings, which is supposed to be a GPU overclock utility. da*! AMD...they've taken to including the RyzenMaster service in their GPU drivers and "auto-overclocking" their CPU's to improve performance even if you're not asking it to. You probably have to accept the agreement before it kicks in, but when you do then.... bam.

https://www.tomshardware.com/news/amd-confirms-its-gpu-drivers-are-overclocking-cpus-without-asking

What I do is run a little utility called Radeon Software Slimmer and remove the RyzenMaster service from the installed driver package after installing my Radeon drivers. It works perfectly for this.

Another method is install the drivers using the minimal install option but that won't install the GPU overclocking packages either. Instead, you can use MSI's EXCELLENT Afterburner utility for overclocking the GPU. That is, if it works for APU's... I don't know.

Have you reset CMOS since you updated BIOS? you should do that too as a safety measure.

I downloaded Radeon Software Slimmer, can't seem to find the RyzenMaster service, where's it?

Also, when I used Ryzen Master, OC mode was on "Automatic OC", is that a Ryzen Master feature or is it bios or Radeon?

It's a bit of a quirky app with it's user interface...

open it, then click on POST INSTALL, then click on the LOAD/REFRESH Software Installed Components banner, then click on SCHEDULED TASKS. Clear the checkbox beside "AMDRyzenMasterSDKTask" which loads the service, then Apply Changes box.

EDIT ADDED: BTW, it's not doing anything that's a deep-dark secret. In this case, if you go into Windows' Task Scheduler you can find the same task and disable it there. It just puts the way to make the changes in a central place so you can easily see the state of it along with a way to change it. The same is true with the Host Services and System Services: you can disable them using Windows standard admin tools if you know just where and which things to disable.

I'm not sure how Radeon Settings, BIOS and RyzenMaster app all play with the full RM app is installed. Probably any of the three can set AutoOC on under varying circumstances since Ryzenmaster CAN CHANGE BIOS settings. Doing what AMD did by adding it to the Radeon driver package makes it confusing to understand what's happening. It's much better to completely uninstall Ryzenmaster and leave it uninstalled IMO...as well as take it out of the Radeon driver installed package.

Thank you, managed to disable it.
Although I discovered something else: it's not the agreement, voltages go up just when I OC the APU through the BIOS, if I put APU on Auto, CPU voltages will remain stable, it's pretty strange.

How are you OC'g through BIOS? Using an 'auto oc' one-click setting? they do tend to do such things.

Leaving VCore voltage setting on AUTO is probably best. But also avoid using any kind of "auto oc" setting in BIOS or anywhere else. They never work well, in my experience.

No auto OCs enabled, gaming boost off, just XMP on.
Everything else is default, except for GFX clock @1650mhz and GFX Voltage at 1.2V.

Well, I think I'm just not going to OC the APU thorough the BIOS at this point, it's not that of a difference after all.

Also, is it normal that on Cinebench or AIDA64 max clock for every core is around 3700mhz?
The voltages and temps are pretty stable, never touching 1.4v.

Another thing I'm gonna try to OC the APU without using the BIOS is MSI Afterburner, gonna try that tomorrow since it's late.

Is this system primarily used for gaming? If so, you're better off not overclocking the CPU at all; only the GPU. There's a couple reasons why: first, CPU and iGPU are in the same package so heating up the CPU with an overclock only serves to degrade the iGPU with it's heat load. Second is the iGPU by FAR has the greater contribution to improved FPS for gaming, you don't want to compromise iGPU performance in favor of CPU when it offers less benefit.

The other major contributor to gaming performance with an APU is memory overclocking: you're already running with XMP but you could go for more if you're the type to tweak with the timings and DIMM voltages. That's not for the faint hearted as there are a lot of timing parameters. You have to go looking for some guides to get started at it.

Afterburner does not OC the CPU, only the iGPU. If you want to use it make absolutely certain you've completely disabled any OC settings in Radeon Settings.

Yes, it is mainly used for gaming, I was not even planning on OC'ing the CPU to be honest.
Since OC'ing the iGPU from the BIOS seems to mess with the CPU voltage, I will definitely try Afterburner.
Actually, in Radeon Software it doesn't even give me the option to OC anything.

Hah...yah I've never set up a system with a Ryzen APU so don't know how the overclocking works. I thought they used Radeon Settings just like AMD's discrete GPU's.

Hopefully Afterburner works out for you. It's really good with my 5700XT in particular.

You do realize that the igpu is part of the cpu, it's not a seperate entity. The igpu has little cache of its own and zero vram, so relies on the system ram for any virtual vram usage, which goes through the cpu, the memory controller.

Considering both cpu and igpu are in part symbiotic, gotta be careful when looking at voltages, you shouldn't take Ryzen Master word for it. The cpu will only use whatever it needs, the cores are not being force fed the full 1.55v.

That's where you'll need to look at HWInfo, to see exactly what the cores are using, not what's supplied because part of that voltage is going to the igpu to sustain the OC, part of that being increased LLC.
