Does the SAPPHIRE Pulse RX 580 8GB have Samsung memory?
Would love to know that too, otherwise I am about to pick up some gigabyte xtr aorus - they have samsung on it.
The one that i have has Hynix (Sapphire Pulse RX 580 8GB), but i get 30,2Mhash while GPU-Z shows power usage of 93W (i am trying to lower the Voltage at the time).
But i am Using Custom Timings, i found them in this forum, at page 9 or 10 i think, with these timings i could get 30,5 Mhash but i think this costs too much power with higher core clock speeds, so i lowered them a bit and i am Happy with 30,2Mhash.
