Hi.
I have a problem with strap settings (-mt value) - the miner can't set the timings

-----------------------------------------------
GPU0: Unable to set VMEM timing to 2 - error: -8
GPU1: Unable to set VMEM timing to 2 - error: -8
GPU2: Unable to set VMEM timing to 2 - error: -8
-----------------------------------------------
Rig is on AMD RX570 8Gb, under Win10, driver 18.3.4 (tried the 19.12.3 as well). Phoenix 4.9c
Miner is running via "Run as admin..."
Any thoughts, what can be an issue?..
