Will it be feasible to fit 6 rx 580s 8gb on a 1000w gold psu with dual mining(dcr) ? I think the new rebrand uses more power than 400 series, or with tweaks is it comparable ?

It uses more power stock because of higher clocks, if u mod/undervolt, the power is almost the same as 400 series.

For dual mining i wouldn't even use a 1200w psu, let alone a 1000w one.
Dual mining with 580's will get you close to 1000w, way over the safe, 80% PSU usage.

Hi Pennywis3 I asked Apneal but he missed that so if you can help I would appreciate that

Today I received one more new sapphire (11265-01-20G) Hynix I used the '777000000000000022AA1C00B56A6D46C0551017BE8E060C006AE6000C081420EA8900AB0300000 01B162C31C0313F17' straps and was able to hit 29.2(1100/2150), then I raised to (1200/2150) and it could hit 30.6 but the gpu-z power draw is 115-116W, I flashed again with 950mV@2000 but there is no change. please advise me how to reduce that I am newbie for voltage issues.

It probably didn't accept the values, as u can see ur are running them at 1.05xV.
Try to set the voltage in Claymore or use Wattool if u cant set it through flash+AB.
Also i recommend u watch your memory errors closely in HW Monitor for errors. Those errors can sometimes make a rig unstable, the miner or the ati driver can crash because of the errors.

The memory errors showing zero and the rig is stable but I wish to reduce the power consumption. Is that possible to use AB to undervoltage? and if not possible how to make wattool load the undervoltage on start up pls as AB do with clocks?
