How do you guys know which memory brand a certain card has? Is it just luck or can we actually buy a card with the specific memory we want?
I'm an old time altcoin hobbyist, about to buy myself a new pc and I was thinking about getting a Sapphire 570 pulse 4gb because it's a reasonable gaming/mining card and I can get one for under 200 but I'm afraid to get crap memories. Should I opt for a different model instead or are pulses (and their memories) decent for mining?
Thanks
There is something like this: http://1stminingrig.com/spot-memory-types-rx-470-480-hynixelpidasamsungmicron/I'm an old time altcoin hobbyist, about to buy myself a new pc and I was thinking about getting a Sapphire 570 pulse 4gb because it's a reasonable gaming/mining card and I can get one for under 200 but I'm afraid to get crap memories.

But yeah you have to be lucky. In CZ Pulse is overpriced we have here very good prices for Gigabyte, I've never have Gigabyte GPU, but they same price for Gaming and even Aorus, price is about 199 EUR. You can find what GPU use which memory, usually 2 types, but they can use them all
I thought when I was buying my second Asus Strix 470 that I will have Elpida which I've already have one or Hynix and I've got Samsung instead I'm verry happy it's my most profitable card almost same hashes as 480 and lower power consumption 
I also have bad luck even with Samsung memory, but you know you can send the card back, right? I've bought RX 480 Dual, few days testing... pure shit... so I give it back and I've got my money back in few hours.
