Not MY fault AMD partners want to label EVERYTHING as a CHL822x. If you have the actual card, you can poke I2C and figure it out, though.

is there a list of regulator id's somewhere ?
Wolf, it's not about my card, i know how to check with aida, i want to implement vddc offset adding with SRBPolaris.

In that case, you're pretty well and truly fu- wait. There is one more way to check - the I2C address itself. Never mind - while the PMBus interface for the IR3567B-compatibles can only live at certain addresses, the I2C interface can be anywhere in the I2C address space. I don't think you can do this with the ROM alone.

It depends. If you don't switch control from AMD SVI2 to the SMBus interface, you can't set it. Well, you can, but the SVI2 VMAX applies instead. You have to first take control of it, then you can use 0x24 to set it.

Thanks, i just found the datasheet for NCP81022, and it's 24h indeed! cheers smile.gif

Keep in mind what I said, though - it will NOT take effect unless/until you take control of the NCP81022 from SVI2. I do this with my tools on purpose - but be warned: the driver will no longer be able to control voltage AT ALL. This means you better be prepared to.

Which is the best bios to flash for a XFX Radeon RS RX 480 RX-480P836BM? I have 2, searching doesn't seem to be working at the moment. Any luck flashing any of the 4gb models?
