thinking of bios modification to my ref vegas 56. Can someone please (that has done it) tells me a good stable config and the pros/cons of all this? does it worth it? already stable 56's with 1880h/s each

You cannot mod the BIOS of a Vega 56, you can only modify PowerPlay tables for Vega. Alternatively, you can use Win10 and the latest beta version of OverdriveNTool 0.2.8beta1. Also, you can swap the Vega 56 BIOS with the Vega 64 BIOS. But you cannot mod a Vega BIOS.

HEllo thanks for your reply, yes i meant swapping bios..do you know any drawbacks like high temperatures etc or all just the same, my problems is that im living in a country with high ambient temps so i cant bear to set the fans any higher already i have a vega fan headache.already using overdrive (older version) to config vegas everything seted up via vega mining guide and powertable

IMO, temps are a big problem for vegas. If you don't maintain the HBM2 temps BELOW 70 C, you will lose hashrate. I didn't not notice a huge increase in temps when swapping 56 BIOS with 64. Greater range for clocks and memory frequency increases temps proportionally. Before messing with swapping BIOS, I'd solve your temp problem first. In other words, why increase the clocks and frequency capability when it is simply going to throttle back?

Totally agree; I've found success with keeping core volts below 950, memory to 800, fans set to 3200 min with a 4900 max, and set target temperature to 66 (you can even try lower if you don't mind the loud noise of the fans).

I've also had cases where the cards run much hotter for no apparent reason and my only guess its a radeon software or driver issue whereby it's ignoring my minimum core volts, driving more volts through the card and making them hotter. A reboot and disable/enable in device manager for each card has fixed this, and then they run 10c cooler until it mysteriously happens again.

I'm on a mixed rig of nvidia and amd, and often wonder if that's not causing me some weird issues.
