Great choice of cards, I bought 20 of these, and they all came with Samsung Memory, so thats a good thing.
The only problem with them is they are 3 slot cards, so they are much bigger than others.
However, if you are able to find Sapphire RX580 Special Edition, then that would be a better option in my opinion.
My Special Edition cards are all 85%+ ASIC Quality, where the power color ranged from 70-85%
Do you know how much each RX 580 will be worth? i only have gtx 1060 here running and planning to build a new mining rig can you give me some idea how much RX 580 each with samsung memory? if i have a very cheap or free electricity i was thinking that its more profitable than nvidia graphics card..
4GB model ranging about 249-279$ , while 8GB models range from 289-599$

Do you know how to modify them i heard that hashing power of RX 580 is 24 mh/s claymore but there are someone reflashing it and increase the hashing power of almost 31 mh/s do you know that tools and how to reflash the Rx580..
Just searched right now from google that i thought the hashing power of rx580 is the same as just gtx 1060.

I got my Sapphire Special Edition cards from the local distributor in my country, got them got 315 US$.
Most 8GB Cards whether 570 or 580 come with either Hynix Memory or Samsung Memory, these can normally overclock to 2150mhz easily, Samsung can reach 2250mhz.
4GB cards can come with Elpida memory, which can barely overclock to 2000mhz.
I just found a video that someone can modified and reflash the program of AMD graphics card from youtube.. i don't really know if its true or not since i only have gtx 1060 i would like to know to other experience miners here that reflashing amd cards could improve the hashing power?
Yes it is very easy even a newbie can do it if he is knowledgeable enough to follow the steps on the video, this video is really user friendly and you can find it in the link below :
