3900x super hot , gigabyte z570 master , vcore auto voltage.

[peter224722]

Hi , I've always had problem with my 3900x on my gigabyte z570 master being to hot.
With the default cooler anything other than windows 10 power saver mode would put the fan on full 747 mode.
Just got a 360mm AIO cooler and found that in AMD Balanced etc , the temperature would hit 74 on idle and the water temp would go up vertical.
Reading that dropping the vcore voltage may help I tried knocking off auto on vcore and used 1v from the 1.2v it send it was set to by auto.
Super cool , but only about 3.3ghz , so tried 1.1v and 3.5ghz and 45c idle so better.
Tried what the broad said was auto ( 1.2v ) and it's now 3.8ghz dropping down a little on 100% cpu after a long bender test.

Now on manual 1.2v and a setting the pump profile higher I'm getting a max temp of about 68c after 2 hours blender 100% work , and the task manager say at 3.68ghz .

WHAT I DO , up the voltage a little more , 1.25 ? , what is a best temp for the 3900x I should aim for , cooler the better or a higher temp , but higher clock speed ?

What tool are you using to measure temperature?

Can you show me a screenshot from Ryzen Master Tool?
https://www.amd.com/en/technologies/ryzen-master

Here's mine with YouTube playing and a few Chrome tabs open, using the stock cooler.

it looks like I can't send a image direct , but need to host the images somewhere else.
When I set the vcore to 1.2v , I'm getting 4185mhz all cores 63c ( 35c idle ), and auto says 4038mhz all cores at 81.09c
But task manager say differant !!! .

OP be aware Ryzen Master likes to show averages. In HWINFO CPU Die (average) will be same as Ryzen Master. Only reason you'll see a difference between those two, for that sensor, will be polling interval, by default HWINFO is 2000ms and RM 1 second.

In this ZIP you'll find a WMV where I'm testing 3800MHz 1:1:1 for ~12hrs on a R9 3900X, HWINFO was the main monitoring tool used for test run, you'll see RM opened just to capture some aspects and other apps.

I think i'm just chasing the rabbit , windows 10 task manager is wrong , if Hwinfo and rayzen master are correct.
So it look like I'm getting 4.1ghz all cores and under 70c on amd balanced profile , which is different again to the auto setting .

Shall I link few posts from Martin stating how pants AMD were on providing info? AMD announced SDK and took ages to even provide them the info. It took several attempts for them to finally get anything out of AMD worthwhile.

In post 3 I clearly stated "In HWINFO CPU Die (average) will be same as Ryzen Master.".

v6.12-3930 is from months ago, some where around end of Sep/early Oct.

Spoiler

Even Ryzen Master has changed between then and recent versions on how it reports aspects.

All I can say is kudos to Martin and others efforts. HWINFO now shows FCLK/UCLK and PPT/TDC/EDC info and has been going strength to strength on monitoring of Matisse.

Another aspect I have noted between the 3x R9 3900X I used with same HW, some can have a larger CCD to CCD difference, post on OCN.

What screen capture are you using ? , looking at your result , mine is similar and very different.

MY 3900X Would often go well into the 80's while pushing well over 1.4v. ive put a voltage offset of -0.100v so it sits around 1.3/1.35v most of the time while being a lot cooler.

You would think that AUTO is the safe bet , no over clocking etc , a base to start from .
Setting the Vcore manually to the same value ( 1.2v ) you would think gives the same result , but increasing the voltage the 1.25v gives a better and cooler result to autos 1.2v , So AUTO may be adding a positive offset value somewhere else.

I've found that on auto cpz says the idle vcore is 1.42 volt , So manual 1.2 and manual on vvc to turbo keep the vcore at 1.2 v full load.
