z790 Hero, Voltages going crazy up

[Salamandrix]

My system I9 13900KS, 32GB RAM 6400mhz CL32. Motherboard Asus z790 Maximus Hero. AiO Ryujin II 360mm. Nvidia 4070 Ti.

For a year,  I've been setting the PCores to 5400mhz, 200mhz down from stock,  and the voltage offset to -0.075.

Temperatures have been OK, normally topping around 55-60C in games and just browsing around 38-45C.

I've started playing The First Descendant a week ago,  and ingame the temperatures go up to 70-75C, sometimes with spikes of 78C. I saw a video of Debauer on YouTube where he was saying that lowering the PCores to 5100mhz and the ECores to 2200mhz would reduce the temperatures even further down, consumption with a bit of FPS hit in games... but not much. 

So I went into the Bios and reduced the Pcores to 5100mhz and the ECores to 2200mhz.

But when I logged back into windows 11, the fans were speeding on the AIO, the temperatures  up to 70C with pikes of 75, until after a while they went down to 55C...with only HW Monitor...

It feels like the motherboard is now pushing the voltage up over 1.65v per core.

And I didn't touch the Voltage. Just the same -0.075V offset.

If anyone has any idea what's happening or how to solve this problem, let me know please 🙂

I'm attaching HW Monitor screenshots. 

 

Thanks in advance

Hi @Salamandrix 

Which BIOS?

When was the last time you reapplied the TIM?

Check to see what the package draw is when playing The First Descendent. I've noticed some games such as Hell Divers 2 hit the CPU quite hard, sometimes peaking around 200w.

Inspect the vcore voltage within HWINFO64 under the SuperIO/Nuvoton section - the VID is the CPU voltage request and not the real-time voltage.

Ok, after posting this, I had to go get some sleep, so I am back up, and when I started my PC, the temperatures and voltage appear as it should be with the PCores and ECores frequency reduction. No idea why before the temperatures where all over the place.

Now, the CPU temperature is between 55-63C inside the main city Albion in The First Descedant with voltage not exceeding around 1.25v requests as you said.

In windows with a 35-42C temperature after starting windowsWhile inside the gameI think this what you requested, but let me know if I'm missing some info

Also my Bios is the previous one, the ROG MAXIMUS Z790 HERO BIOS 2301 from 2024/05/30.

I haven't installed the latest one (ROG MAXIMUS Z790 HERO BIOS 2402 from 2024/07/12 with the "Updated with microcode 0x125 to ensure eTVB operates within Intel specifications.

When you asked me about TIM I guess is the Thermal Interface paste? I used Kryonaut Extreme - Thermal Paste and it was applied a year ago around July 2023, when I installed the second KS CPU, because the first one came with 2 Faulty PCores and RMA replaced it as fast as it could as there was no stock(had to wait 20days)

If the TIM is a year old, consider replacing it—especially Kryonaut Extreme as it tends to dry out quickly in my experience. Voltage and temperature looks fine from HWINFO screen grab.

I still have to install the new BIOS, but I have special FAN Curves for the AIO Fans and Case Fans so they keep the case cool and AIO with minimum Sound Vibration with a slightly different speeds so they won't resonate. So every BIOS update I have to redo the FANs Curve in the BIOS..... It is tedious lol

Save the fan profile via OC Profiles under Tools to a USB pen drive.
