So it seems aftermarket cards use Hynix memory and do not seem to overclock so well? Few I have seen struggle to maintain 950.
Were 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?
Yeah maybe. I thought it was common to get them to run 1100mhz.
As far as I know, if you have a V56 with Samsung, it should be able run around 1100Mhz, but you have to flash a V64 BIOS on it.
For my V56 with Samsung it works.
