VBIOS flash supported for RX 6600?

[Dojo76]

I tried to save the bios of a Sapphire RX 6600 but I always get:

AMD VBIOS saving failed in HiveOS.

I had a look at the flash tool message and it’s unable to find the adapter:

AMDVBFLASH version 4.71, Copyright © 2020 Advanced Micro Devices, Inc.

Adapter not found

Is it possible to flash VBIOS for the RX 6600?

I found out that firmware 113-2447LHS-UDB seems to have different memory settings compared to 113-2447LHS-UDG, is more stable at lower voltages so I’d like to flash it

Hey!! could you solve it? I am having exactly the same issue and my RX 6600 XT is just doing 28.4 MH

No hope, I downgraded to UDB but with very little improvements if any. On same cards memory needs more power, is not stable if undervolting to less than 1140 mV

I used AMDVbFlash tool, backed up the bios I need from an identical card and then used it to flash another one
