Anyone running Sapphire rx nitro+ 570 8g cards with Hynix memory at a rate higher than 25 Mh/s?  I can't seem to get the cards to run over 25 Mh/s even when running blockchain drivers and with running 1750 straps or the uber straps.  Hoping someone has found a way to make these things worth it.  I can get the cards with Micron memory to run at 27 Mh/s, but can't get any more with Hynix memory.  Looking for some suggestions.
