RX 5700 XT memory clock stuck causing high temps when idle

Jump to solution
My RX 5700 XT memory clocks are stuck at 875 mhz (according to wattman) and 1750 mhz (according to gpu-z) at all times - when gaming and when idle in windows with nothing running on the background. Problem persists on a fresh adrenalin driver install without any changes made after installation. Memory being stuck on it's max state causes higher power consumption than intended when system is idle and it leads to 58-68 celcius temperatures even when nothing is running on a system (not even a movie or youtube). Gpu fan is running at 600-700 rmp at that time on a well ventilated system (2* 140mm fans intake +2* 140 mm exhaust), ambient temperature is 24 celcius. I tried clean driver installation, used DDU (display driver uninstaller) and AMD cleanup utility the other time, another displayport cable, tried to disable all windows fancy effects - all that to no avail. Manually changing refresh rate on the monitor to 120 hz from 144hz fixes the issue and gddr6 memory get's unstuck and becomes able to clock down when idle - from 875 mhz to 100 mhz (according to wattman). The monitor is 2560*1440 144hz connected via displayport 1.2. Manually changing refresh rate to 100hz or to 75hz using 2560*1440 resolution still leads to gddr6 memory clocks being stuck at their max state.
Steps to reproduce:
1) download windows 10 install files from Microsoft official site, create bootable usb drive and perform fresh system installation.
2) download radeon software adrenalin edition 19.7.2 and install the driver
3) install the monitor driver from the official site
4) restart computer after driver installation get's completed
5) open wattman in radeon settings
6) make sure there are no background processes that could be demanding on graphical side
7) check memory clock and temperatures of the card in wattman - gddr6 memory clock is at 875 mhz and temperatures are at nearly 60 degrees celcius mark
😎 open windows settings - display - additional display properties and set monitor refresh rate down to 75 hz or 100 hz (2560*1440 resolution)
9) check memory clocks and temperatures in wattman - there are no changes, memory is still at 875 mhz
10) open windows settings - display - additional display properties and set monitor refresh rate to 120hz 2560*1440 resolution
11) check memory clocks and temperatures in wattman - memory is now able to clock down to 100 mhz , power consumption in idle state has significantly dropped too, temperatures are slowly going lower, gpu fan remains 600-700 rpm speed.
Turning freesync, gpu scale on/off, changing colour depth leads to no avail. 
I reported about the issue directly to AMD but would like to know if anyone with a similar problem has found better solution than turning down native monitor refresh rate.

I checked with the product team and their feedback is that depending on specific display configurations (resolution and refresh rate combinations) and background tasks, RX 5000 Series GPUs may maintain memory frequency to ensure an optimal user experience. This behavior is expected and does not impact the RX 5000 GPU in any way.

Seams to be a lot of issues with the 5700 series GPUs. Such a shame they really have promising performance vs Nvidia, but if you have to deal with a multitude of issues it makes the lower price not worth it. So far legitimate issues reported with these cards are.

1. Eventually runs so hot under load the GPU shuts off the computer.

2. Card shipped with bios corruption/bugs that prevent stats from reporting to the driver correctly or at all.

3. Memory runs far too hot damaging performance.

4. The cards are seriously memory speed limited so overclocking yields little to no improvement. 

These issue are serious enough that they will not likely be fixed anytime soon. This underminds the reputation of Navi in the pc gaming community and bolsters RTX just like last generation with vega. Such a same.

Im still waiting on my replacement 5700XT 5AE that suffered from all the issues listed above.

So in your point 2, you mention bios corruption/bugs preventing the sensor data coming through.

How do you know this is bios corruption or a bug and not driver related?

Mainly because in my experience with GPUs I've seen this behavior before and it normally is due to bios corruption or a bad factory bios flash. Also, I uninstalled and reinstalled the latest driver several times using the DDU tool and it literally had no effect on that issue.

Have the same problem with my Sapphire Rx 5700.

Tried a few combinations:

144 hz @ 1080p or 1440p = MemClk 875

60, 120 hz @ 1440p = MemClk 100

50, 60, 120 hz @ 1080p =MemClk 100

Your instructions works perfectly. Hope AMD can/will fix this soon with driver update.

Facing the same issue here when using 3440x1440 resolution. Tried 60Hz, 100Hz, 118Hz, all results in the memory being stuck at 875.  Lowering resolution does work, but that's not ideal.  Hope AMD sorts this out asap.

Edit:  this is on a 5700XT and Windows 10

Edit2:  changed from DP to HDMI and now 3440x1440 is working at 100Hz refresh (max of monitor).  Still would like to see this fixed for DP

Edit3:  turning on HDR in Windows will also cause memory clock to be stuck at 875

Edit4: drivers version 19.7.5 has resolved the HDR issue.  DP issue still persist

I have the same issue at 144hz memory does not down clock. Using freesync premium setting on my benq ex3203r freesync 2 monitor which reduces the monitor to 120hz and was working with an rx 580 is now locked at 60hz (ram down clocks) with the rx 5700, so there is also an issue with their freesync 2 support in the driver.

I just wanted to add to this: Memory clocks stays high at 875mhz on my 5700 xt on the 19.7.3 driver when running dual monitors (2560x1440@144 & 1920x1080@144) causing idle power to be higher than it needs to be, this is fixed when I run a single monitor and it drops down to 100mhz causing idle power to plummet aswell.

Interesting, does it downclock to 100 mhz with any single monitor configuration (1440p 144hz and 1080p 144hz) for you?
What type of connection do you use in a single monitor config for  each? (Displayport 1.2/1.4 or hdmi 1.4 or 2.0+)?
In my case the problem is still here on 19.7.3 driver with LG 32gk650f (1440p 144hz) connected via displayport 1.2.
I don't have hdmi 2.1 cable to test (and 1.4 version can't provide enough bandwidth for 1440p 144hz) and i wouldn't use it even it worked properly since freesync range with any sort of hdmi connection becomes limited to 60-100hz accordinng to LG's manual while it is 48-144 with displayport.
And It doesn't look like the cable/monitor monitor issue since it works flawlessly on my second pc with vega 56

Ok so this spawned an interesting scenario: Only the 1440p Asus MG279Q(freesync on, DP1.2, mini and standard DP has the same results) monitor solo will drop power consumption, the 1080p Philips 242G5D(no freesync, DP1.2) monitor solo will have memory clocks stay high.

I used to have a vega 56 aswell and things worked fine there.
