450 h/s in v3.2, 460 h/s in v3.3. Stock clocks and bios, 280x powercolor, hynix memory, no riser. It seems I have to check this problem only remotely with logs, so it will take more time to find the reason.
What if the problem is in memory type? Because I have the
elpida memory and I get only 360 h/s.
