RX 5700 XT stuck at 875 HZ MCLK at 144 HZ

have to give additional feedback to RX 5700 XT having elevated memory clocks while idling on max refresh rate - in my case it is 144 hz. The memory clock is stuck at 144 hz regardless of drivers - 19.7.5, 19.9.2, 19.9.3, 19.10.2.


My monitor is LG 24 GM 79 GB. Graphics: Asus Rog Strix RX 5700 XT 8 GB OC. Downgrading to 120 hz refresh rate causes the memory clock to be able to go down to 100 hz, instead of 875, at idling. But not running your hardware with its specifications is not an optimal solution. 


In the web, you can find similar experience from people on different AMD graphics cards, Vega Radeon VII, RX 580 etc. While others can actually run 144 hz with memory clock being 100hz or 300 hz while idling, depending on their monitor.


The elevated memory clocks may be a part of the issue with having RX 5700 XT crashing in many games, including the newest 19.10.2 drivers (crashed in Battlefront 2 every time regardless of Enhanced Sync turned off or on). 


Some help with this issue would be appreciated.
