Just tried it with nothing more than 150Mhz extra core clock, saw it boost to 1577, and stayed at 53c.
Will try and c how it do in games, as I just got it, so will c how stable it runs, would like to have it up at 1600Mhz :-)
No OV, No extra mem clock.

Bought mine some days ago, just got it 2 day, installed it, tried first with 100Mhz extra, as I saw Jay2Cent run it at 1500Mhz without any problems, mine took the 100 while staying at 53c, dropped 50Mhz on top, stayed at 53c, and ran test without any problems, but one thing is benchmark's, another games, will c how it do, so fare no OV or MEM OC.

Ok, so tried to run it at 1500Mhz, & it got zero problems with staying at that OC, did not touch mem. or voltage, did just put little extra on core Clock, run games smooth, but sure, jumped the gun a bit, now the 1080-1070 r just around the corner, but the offer was so cheap, and with the new WinX, where u can mix & match GPU's as u like, can always use it as second GPU, or for another PC, cant say I seen any GPU OC that much out of the box!!—May '16
