As mentioned, PCS+ R9 390x. Stock frequency is 1060mhz/1500mhz
Overclock -> I can get to 1120mhz/1600mhz on STOCK voltage. No added voltage, +20 power limit, no extra juice at all. Once I hit 1150, its almost like a voltage wall. +100mv in msi afterburner, and theres still artifacting. Powerlimit to 50, and still artifacting. Even downclocked the ram to 1400mhz, still no joy.
Swapped to "Trixx" for the +200mv, and it still doesn't work. Artifacting, crashes.
Is this "normal"? 1120/1600 vs 1150/1400 with +200mv just doesnt seem right. Any ideas?
