Hi guys! I need help with this
I have a 5600 xt sapphire, I was using the last drivers of amd, 2021 version (not sure which), and phoenix miner 5.5c and:
After I flashed the bios of the youtber: Red Panda Mining, the video is called "BIOS MOD for the RX 5600 XT For Ethereum Mining" I follow the things I have to change in the bios, video: ULTIMATE 5600xt Ethereum Mining Guide, by: Son of a tech
So, the bios worked, I started phoenix miner and instead of use 78-79W, now with this new Bios Im using 120 W (reported both by Radeon Software and Phoenix miner), and I undervolted to 690 with More Power tool, rebot and,Randeon software shows 690-690-690, and still at 120W power usage reported by radeon software and phoenix miner. I just flashed the previous Bios for my sapphire 5600 xt, and undervolted to 680, Radeo SW reports 679-679-679 in options, and while Im farming it show in the single display 681mv. So now the Power consumption reported by both programs again, is 73W. Not sure what I did wrong, but for 3.9 more Mhash, at the cost of like 30W more, dont worth for me.
EDIT: okay, Im trying it again: 43.8 Mhash, at the cost of 120W and temp 44°-45°, but the temp is the same like when I was using the stock Bios (just modified with More Power Tool, results was like 40.3 Mhash at 77-78W and temp 45°). This is a visual bug? I will try to add screenshots.
EDIT 2: screenshots


Now Im using the drivers: 20.12.1
Don't take into consideration what the SW (driver) says about power consumption. Use a kill-a-watt and measure it a the wall. You should get the same power at wall for both non-modded and modded bios, just the Mhs is higher in case of the modded bios. I did the same for my 5600 XT sapphire Nitro cards and all are hashing at around 41.3 Mhs (43.8 was not stable long term) @ 95W at wall.
