RX 5700 XT 50th Anniversary Edition core clock rate is buggy

[DedEmbryonicCe11]

The main screen of GPU-Z has blank clock speeds and the sensors tabs shows ridiculously low idle clock speeds (6-22 Mhz??)

Yet in the reviews I see online examples where the clock speed is displayed properly with the same 2.22.0 GPU-Z and vanilla 5700/XT cards. Anything you need to bugfix this?

these are accurate, the card really clocks down that much

i haven't found a way to read the clocks that amd claims in their spec sheets, instead of showing "800", which i can read, i decided to show 0 until a fix is found

Weird I've even seen it adjust the clock in single Mhz increments like 18->19 Mhz and then fluctuate around. At that point can you measure power savings versus locking it at 25/30 MHz and calling it a day?

Do you know what software reliably reads the core clock so far? I can get a single data point at the end of a 3DMark run but other than that all I know is the boost clock I'm targeting in Wattman.

It seems the clock and voltage values are averaged over a short time period, so you'll see it drift around from time to time. nothing gpu-z has control over

there is none

You should be able to see core clock in Wattman, or does it also have bugs.

Im also getting the same issues my GPU CLOCK ranges anywhere from 6mhz - 4000mhz i have no idea whats going on, isnt it supposed to be at a stable clock speed?

the card will dynamically switch speed depending on the situation. down to 6 mhz is correct. 4000 mhz doesn't look right though. what does gpu-z show?

Today it peaked at 1996mhz, on Wattman the other day it was 4006 mhz (peak) - but the speeds literally jump up and down every second anywhere in the 6-4kmhz range.

during gaming?

you should see clocks between 1600 and 2000 or so. below 1600 only when idle or watching video

In the CIMManifest.xml file, from the Radeon drivers, is a full list of codenames from AMD btw. I don't think they are fully implemented in GPU-Z yet. For Navi:
