144Hz elevated memory clocks at idle

Jump to solution

Hello

My XFX RX580 8GB elevated memory clocks at idle on desktop if I set 144Hz refresh on my monitor  .

When I set 120Hz or less then is ok 

144Hz :

2000Mhz Vram

120Hz or less :

300Mhz Vram

This is driver bug or what ?

No it is not a bug, it is expected for the 580 to use a higher memory clock when running 144HZ.

I guess it's not a driver problem. This problem happened to me. This kind of problem may occur if you've edited monitor settings with CRU. If you don't use CRU, you can try editing for 144 hertz values with CRU. Note: CRU software may damage the monitor.

It is mentioned in the driver known issues section as a bug regarding Radeon Vii (but it seems to be the way amd mention bugs that they akwnoledge by marking only their flagman solution).

The issue looks to be pretty common for all amg gpu's: 
RX 5700 XT memory clock stuck causing high temps when idle also had it on RX 590 

 

But have to mention that i don't have the prolem when i connect the exact same 1440p 144hz monitor to vega 56 via the same connection (dp 1.2)

Still can't answer whether it's a hardware or the driver bug.

It appears that this is a driver error if it is on the know issues list, but not only on Radeon VII but RX series too ?

I try this Solution:

https://www.reddit.com/r/Amd/comments/dr5bxt/i_solved_my_max_memory_clocks_at_144hz_problem/ 

and work for my

 I created a new resolution of 144 Hz in the CRU program with the LCD standard parameter, memory clock speed decreased to 300Mhz

Why now, following reddit tips, 144Hz works at a lower frequency 300Mhz ? 

No higher memory frequency needed

It's a bug! How do you explain the custom 143hz then ? It's working in my case if i use that refresh rate. The clock speed decreses when i'm on my desktop as it should.
