well, it was an error in my notes...so, pretend the v3.2 never existed I delete it from the first post

Just use the v3.3 set if you memory can't clock past 2100-2125Mhz (i have two card and both are 100% error free using these)
If you can clock your vram past 2150-2175 try the v3.4 set (it's 95% stable for me, some EDC error, no corruption). Also try to set the IMC voltage to 1050mv (I use the "hellm" bios as base), it helps when clocking past 2125Mhz

Hello, guys! Please help me, I believe you can. I have 3 cards MSI Armor OC 8gb RX580's and I've edited their vBIOSes with Polaris Bios Editor and SRBPolaris 3.5 to slightly downclock and downvolt core of them to 875mv and after that on my Windows 7 rig with "dag fix" drivers atikmdag 22.19.659.1 27.07.2017 they showed about 938mv in AB (v 4.4.0 beta 16) and thus I've downvolted them via AB to about 900-912mv (that was my goal) and all was ok and stable. I'd mention that I've set static voltages (like 875) in PBE for all core frequencies (at first I've set 900 mv, but after the problems I'll describe further, I set it to 875, but result was the same). Now I've had to migrate to Windows 10 and: with the same drivers (but from separate .inf file that is for windows 10) they show 938mv in HWinfo, but AB voltage monitoring and control didn't work (the slider was greyed) whatever I did.. Then I've followed the instructions to set VDDC_Generic_Detection=1 in AB's cfg files and this enabled the slider (but not voltage monitoring) and minimum voltage to set is 800mv, but it appeared that with this slider I can only increase voltage, but it still doesn't go lower than 938 mv. I also tried OverdriveNtool and it also only can increase voltage.. I've been doing all this mostly blindly, not knowing the vBIOS algorithms and/or formats. So, can you please:
1. Advice me how to get voltage monitoring/control in AB enabled (maybe different drivers/AB version, etc)
2. Explain why this low limit of voltage (938mv) appeared and what causes it (driver? vBIOS?) or point me to some guide or FAQ where it is explained.
3. Point me to some guide or FAQ to Polaris vBIOS algorithms, tables, PowerPlay, vBIOS and driver interaction, etc because I'd like to know what I'm doing and I still haven't find any..

@hellm @generaleramon
Could you help me with bios editing for my msi rx 580 gaming x+? My card can't get stable 2150mhz memory clock even with ubermix 3.4V and 1000mv on IMC set over OverdriveNTool. After 5-15 minutes(depends on power target) on 2150mhz card starts getting EDC errors. Also is it possible to change passive mode temperature for 50 degrees, because stock target has 60 degrees and my card in some AAA games turns off fans and only for a while turns them on to cool gpu under 60 degrees. Additionally, I want push card's core clock as far as possible, so I wonder how do I set stock voltage value for 1200mv? In attachments you can find fully stock bios.

Your fan table is this:
01 17 00 00 02 00 1D 00 00 09 03 A0 0F 64 19 34 21 D0 07 A0 0F 70 17 94 2A 01 64 00 E4 12 60 09 28 9A 01 00 46 1C 96 00 96 00 64 00 96 00 96 00 96 00 64 00 01 3B 3C 00 00

01 = ZeroFan Enabled
3B = 59c Fan Stop
3C = 60c Fan Start

i changed it to
30 = 48c Fan Stop
33 = 51c Fan Start
and some other fan related stuff.
The memory clock might be limited by the IMC, you can't really do a lot about it....
Remember to patch the drivers to use the modded Bios (https://www.monitortests.com/forum/T...-Clock-Patcher)

How can you edit the throttling temperature? Mine starts downclocking at 80C. No way to change this.
