best is to blow the air OUT of the room, no need to pump in fresh air.

60 days to spend your money from the card, but it looks like no more card loading...

f you dont get mem errors or rejected shares i would say don't worry be happy

Maybe it can go 32 but you wouldn't be killing it on those mhz in 24h mining, wouldn't you?

So, 30.2 is not enough?

you can ask 10x times, but i don't understand what do you ask.
I guess the others feel the same as me.

bad mem straps can make this happen too

you can but it's not 100% that it will be applied.

Or i would say maybe even less than 25%.
So far i only seen vddc offset added to some sapphire and powercolor cards, and i opened 'bout 40-50 polaris roms.

DDU and reinstall drivers again.
Maybe you played with an OC app, and some of the settings got remembered (maybe voltage), and that's why the cards keep crashing.

i would love to see a 8 gpu rig, 8x570 4gb

This reminds me of teleshopping

DDU radical 

V2.6

- Editable options: VendorID, DeviceID and Subsystem VendorID
- Added 'Small power limit' option to Powertune
- Added 'Clock stretch amount' option to Powertune

Download and run DDU, it should fix your problem.

haven't seen so much non-sense talk in a while 

probably 15.12 not supported on win10

That would be 0xF8 x 6.25mV, not 0xF8 like you said earlier.
Did you try changing F8 to 00 in hex editor and checking the voltage in gpu-z as i suggested ?
It will be higher.. for 1 step, which is 25mV..

Third option not working on RX5XX cards

31ghs not bad at all
