Recently I have bought some new 580's(Nitro+ & reddevil) and they overclock so easily.
The problem is that I have many MSI 580 8GB Hynix and Samsung that will only reach 28.2 Mh/s and 29.4 Mh/s respectively.
I have even taken one of the cards apart to improve the cooling as the thermal tape was poorly applied. I even added some mini heat sinks above the memory chips - Made no difference
I have also tried many custom bios and millions of Claymore tweaks.
I always end up with the same problem where if I increase the memory speed over 2000, I get memory errors as seen via HWINFO.
Had anyone got these cards running efficiently over 30 Mh/s ?
