What makes you say don't use 2 PSU's?
Is bad for the cards?
I am working on a rig that will use 2, 750W PSU's
The reason being that I am also running storage on the rig.
so need to power 5 HDD's, 5 GPUs + fans
Just curious why you say no 2 PSU,

I got some RX480 8G Sapphire Nitros with micron memory SN: A1704.... Bad luck :\
Is there anything I can do to get more hash from these?
Now mining low power mode...
I'm now mining Ether 25Mh/s each and Afterburner showing 65w.
Settings 1050/1750 and -97 Voltage.

there is a 30MHlowenergy rom link in the last page.
All of my Sapphire 480 Refs rigs are with "28MHlowenergyOK" rom, but I have one or two rigs with 30MH one... not bad on ETH mining however ETH mining consumes too much power and too much heat -- it's like a death sentence for the card, stretching it beyond 30mh is not good because for ETH you need stable cards -- having the low power roms and slightly faster than 25/26MH like 28MH or 29Mh is good enough.
Does that low energy ROM work on the 4GB card?
Okay well I just went in and did it cause I love getting more MH/s..
Currently at 30mh haha, this is kinda ridiculous
Just gonna run 1 card at that rate overnight, make sure its stable..
Edit* 2100mhz producing a lot of invalid shares, down to 2000mhz and looking constant 29.5 so pretty happy

There is some Elpida mem out there, that even when modded with the 1500 strap, that seems only stable at 26-26.5 mhs or so
I experienced this with a 480 4gb nitro (not nitro+)
I experienced this with a 480 4gb nitro (not nitro+)
They do 30Mh as well.. (those nitro's)
Got 2 Elpida 4G's, one nitro and one non nitro, the nitro one does 30+ and the non nitro one does 29.5 stable.
But this is with custom timings.
Greetings
I can post the ROMs that I am using to get 25 mh if you want to try and edit them and I can test, sadly I'm not too comfortable at editing them myself even though I feel the info posted above is more than enough.
I am about a week away from turning my 3 pc's into 1 unit with risers so am in no rush to re flash the cards for the next few days
You should be able to get 28-32 mhs even on a rx 480 sapphire nitro.
Download your bios with atiflash, open it in polaris bios editor.
Copy the memory timing for the 1500 or 1750mhz to the 2000 mhz and higher blocks.
I believe you can copy 1500mhz memory timing code to 1750 and 2000 blocks.
Make sure you backup original bios first.

I don't think you can reach 28 mh's on this card surely. It's 4GB the one I got, if it were 8GB then yes possible. Right?
Haha, i honestly was thinking, no way, that's impossible.
So i checked the rom i uploaded, of course, it's the wrong one
Will upload the right one as soon as i get at my office.

Turning Idiotic mode off again...
Mate if you are still around you made my weekend with this!
Running 25 mh/s dual mining with Sapphire 480 rx nitro 4GB!
Stock 21.5
Previous OC at best was getting 23-24 and was very unstable. Sometimes less than 10 min,
You cranked my MH and my fan speed well down too.
Thanks buddy!
