So it seems aftermarket cards use Hynix memory and do not seem to overclock so well? Few I have seen struggle to maintain 950.
We’re all reference cards Samsung memory?
Mine are Samsung (Vega 56) One card can't go stable beyond 900. Some of them start failing around 930. One I tested worked at 980 but I don't know which one now and it takes forever to try one by one. So currently my rig has 1 card at 900 and 5 cards at 925. Maybe Samsung mem is overrated?
My devil 13 cards only does 900mhz/950mv
I tried red tweaks made it even worse, tried voltage also did not help.
