Title: ASIC quality correlation to undervolting potential RX 580 Post by: sc8nt4u on June 22, 2017, 11:36:13 AM I have 8 RX 580s, 6 of them ASUS RX 580 8GB and 2 of them XFX GTS Black Core Edition RX 580 8GB.
In GPU-Z, my ASUS cards' ASIC quality ranges from 69 - 76%, while both my XFX are >76%. My two lowest ASIC quality ASUS cards, 69% and 70.2%, require 25 more mV more at 1100 core clock while mining (825 mV). All the other cards are stable at 800 mV, including XFX cards which are clocked higher at 1175 core. There seems to be some correlation between ASIC quality and undervolting voltage, but at the moment, with such a small sample size, it is just anecdotal evidence. How about you guys?

I have an rx 580 Sapphire. Where in the GPU-Z to see what they are? What does the ASIC and XFX show?

Yes, it's true, it is well known that there is a correlation between the ASIC quality and undervolting voltage. So if you buy cards that are factory overclocked higher than other cards, you have a good chance at getting higher ASIC quality, and therefore better chance at getting a card that will undervolt better than others.

How about you guys? 825mv and 800mv are outstanding numbers my sapphire gpus being 78% asic quality cannot handle 825mv have to run them at 850mv for stability |
