My RX460 2G do, with TRM 0.5.6 + mmpOS over 500h/s
(Hynix and Samsung mem, 1000mV, lower than that they all at some point fail. Straps copy/pasted ofcourse.)
4+3 for 16CU and 3+3 for 14CU
4G cards could try 5+4 and 4+4
:BAB is a good default tweak on these cards.
My fanless 460 2G too, makes my 580 look stupid lol.
