Missing data for AMD Ryzen 7 5700G

If I click on Lookup I get: https://www.techpowerup.com/gpu-specs/radeon-vega-8.c3768

The same I get with GPU-Z 2.41.0

Interesting, for some reason the driver doesn't return clocks, despite it being installed.

Does a reboot or graphics driver reinstall help?

I updated AMD Drivers last time and than I switched back. But the Redeon Software shows the clocks

I removed the AMD Redeon Software 21.8.2 and now it looks better

But the GPU Clock should be 2200. And the BIOS Version will be not shown. Like in CPU-Z or Ryzen Maaster. Is set to Turbo Mode in BIOS.

GPU-Z gets the clock frequency from the driver, which apparently doesn't return the correct clocks.

Will be back from holiday next week, will check for options then

BIOS Version
For some reason it can't read the BIOS version on some APU systems, haven't figured out yet why. You are running with UEFI boot?

You've set 2200 MHz in BIOS, right? Or through Ryzen Master?

This just looks like OP is on an old/bad BIOS? Or maybe 21.8 is bad? I've never seen GPU-Z fail to report info for 7nm Vega 7 and Vega 8.

Does this mean that it will never be possible for GPU-Z to read OC iGPU clocks on its main screen for Renoir and Cezanne? I use HWInfo for that but don't recall ever seeing correct core clocks on my 4650G/5600G/5700G in GPU-Z (2275/2350/2300MHz).

Never say never. Just needs to be important enough for me to put in many hours to work around AMD's software bugs

I mean, I can't say I blame you. For a while back there AMD firmware on i think AGESA 1200 couldn't even figure out what its stock clocks were supposed to be for Cezanne Vega 7 and 8 :D

Also, I don't think GPU-Z is reporting the right voltage for iGPU. Even if just transient and fluctuating, 1.437V doesn't make any sense.
  • #1 If it's at stock iGPU clocks, VDDCR_GFX is dynamic and varies all the time but usually doesn't exceed 1.0V
  • #2 If it's set fixed clock at anything not stock clocks, VDDCR_GFX = VSOC as a static rule, barring minor disparities between the two (~0.01-0.05V)
  • Not sure exactly how the new iGPU Curve Optimizer and PBO works yet, but seems like it only applies when no static OC set for GPU, otherwise #2 still applies
iirc it still works exactly the same way as Renoir minus the iGPU CO and PBO so applies to all 7nm Vega 6/7/8
