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?

Only 1200? I also have 2 rigs 1 is with 2x xfx 280, gigabyte 280x and r9 390. The other is 4x xfx 280. How much power im using? I have 2x1300w plat. But not sure if i use the powrr at all i cant out watmetter becausr i am already out. Did you know any other method to check the powe that tge rigs are consuming? Thanks you in advanced.

My 2 rigs (7950+7950+280 & 290x+290) are using about 850w, so i think one 7950/280 will take about 150w and 290(x) maybe 200w... so I think your 4x280 rig would take about 600w only...

Ok thanks you.
