Graphics Cards

I just noticed my GPU Memory Clock reading 3,000+ Mhz in HWinfo64. I have been just browsing the web for a few hours so there should have been virtually no GPU load at any time since I started HWinfo64.  I am kind of at a loss because I am not running any OC. Everything has been running well at stock settings so I saw no point in tweaking anything beyond turning off ZeroRPM mode in Adrenaline and enabling advanced fan control. Attached is an image of the read out. Any ideas or help would be appreciated.

I ran Time Spy and this is what results look like. While HWinfo64 reports max of 3,024 Mhz, the benchmark reports 1,990 Mhz. I don't know which to believe and what could be causing this if it is a bug.

Disable all non windows apps from startup in task manager and/or from each app (that includes any fan control and/or oc app.)

If that changes/lowers readings, one of those apps could be the issue.

I was able to get in touch with someone at HWinfo and they told me that the GPU Memory Clock has been buggy for quite some time now. Basically, it is a driver error and I shouldn't be too concerned.

@cpurpe91 what is Radeon Software showing?

You could also use GPU-Z's Sensors Tab for graphs that show the changes over time.

Just in case I'll run gpuz while I game later to see if it reads different. Last night before I went to bed it stayed around 1988 to 1990 on my HWinfo osd while I played Splitgate but when I exited to desktop it shot to 2300. I did do a fresh re install of the drivers too. DDU in safe mode then restart and install 21.11.3. Thermals seem fine. Just because I haven't said system consists of

MSI MPG X570 Gaming Edge Wifi

Ryzen 7 3700X

4 x 8Gb DDR4 3200mhz Corsair Vengeance RGB Pro RAM

Gigabyte RX 6800 XT Gaming OC 

1TB NVMe WDBlack SN750 PCIe 3.0

1TB Crucial MX500 SATA SSD

Corsair H100i Elite Capellix AIO 

Corsair RM850x 850w PSU

SO GPU-Z also showed a GPU memory clock that is quite high. Next I will see if Adrenaline shows similar results. I hope my card isn't busted.

One thing I think fixed it is exiting Wallpaper Engine. We'll see. Hopefully I don't need to save up for a new motherboard and PSU. That is what I will end up doing if this doesn't fix it.

So I just got done playing some Halo and it isn't fixed. Could it be that there is a bug at the driver level, and it just isn't reporting correctly?

Please refer to the 21.11.3 driver release notes.

Known Issues
Radeon performance metrics and logging features may intermittently report extremely high and incorrect memory clock values.

You can safely ignore this since it is just a software reading error. Your GPU memory is not running at that frequency, so please do not worry.

Hey, sorry to necro this post, but I'm seeing similar behavior with memory clock on my 6700xt. Found few people with the same thing, but other cards. Have you ever figured it out? It seems to only happen when I'm using Freesync and I am tabbed out of the game. When I'm playing it's sitting at ~2000 like it's supposed to. I assume this is just a reporting error caused by freesync and I can safely ignore it?

[cpurpe91]

I am pretty sure it is just a problem with the readings. There was a note for on the release notes of drivers for a really long time, and I don't remember reading if it was fixed. I can confirm my RX 6800 XT still has this issue.

[qazqazqaz]

Yeah, I went through the release notes and never saw it fixed, they just stopped putting it into known issues, I think. Thank you for the answer, guess I should stop worrying about it.
