Does anybody tried on Sapphire Nitro+ Rx 580 4gb?

Yes, increase REF to 12.

It can be increased up to 100+ for RX 5XX cards. But max stable amount depends on overclock and card quality. This parameter must be select individual for each card. Just need to try and if GPU start give incorrect shares lower REF parameter. Or increase it step by 10 and look into speed and stability...

what exactly is Refresh here? the 5 value added newly? why wasn't it around before? how it links to other refresh timings "tRFC"... so increasing it (beside the strap being already customized for CN or ETH) tends to give better performance? I do mine CN Heavy variants still. let me know
