I have 2 rigs x6 msi rx480 8gb cards(ellesmere 1303/2000 stock) on win 10, z97 gaming mb and 8gb ram, 1200watt psu.
Rig 1 has a small overclock of 1350/2100 using afterburner, tried the same on rig 2 and one of the GPU's crashed.
I am getting roughly 720-750 on each rig, 120 - 130/s per card. Is there anything else I can do to increase speed? I'm not sure what mod I would need for the cards bios or how to do memory overclock. Any help is much appreciated.(I am happy with these speeds but would like to learn how to push the cards harder)
Also, what does undervolting the cards do? Is that just to lower power consumption or does it help increase speed?
Undervolting core allows it to maintain the top speed without overheating. Increase the voltage on memory slightly increases stability.
Theses settings are 100% stable; I use them for gaming and mining:
Core clock - 1350
Core volt - 1135
Mem clock - 2200
Mem volt - 1100
Set target fan speed to max and target temp to 70C so that it does not throttle itself.
