Best efficiency settings for Radeon RX 480

[pikachuy]

Great thread pikachuy, can't wait to try your settings when my lasts RX480s come to my house, and finally build my first rig..., with 6x of them but (Saphirre 8GB not 4GB models), hopefully i will reach a low power consumption, with nice settings like yours, because the price of Kw is 0,15€ cts here

Thanks 

PS : I think for be right back the ROI of the rig faster the dual mining for exemple "ETH - SIA", should be a great idea, did you try to find some good settings for dual mining with a nice ratio of undervolting aswell ?

Hi, our residential home has a 15amp circuit breaker. So since each rig is about little under 700watts at the wall, I place 2 rigs per breaker safely. So that is about 1400watts running at the wall on a 15amp breaker. I believe a 15amp breaker maxes at 1800 watts before it trips. So if I dual mine, the power increase might trigger my circuit breakers, and I don't want to be that close to maxing out in power on each circuit breakers. I want a little cushion in case for spikes or other safety issues.

But if I was only running 1 rig per breaker, then I can definitely dual mine because there will be extra power slacks for me to play with. So with a 2 rig of 6x 480 set up on a single 15amp circuit breaker, in my opinion it would be best to underclock and single mine only. But if you have like a 20amp circuit breaker, that is a different story.

these settings are great
but as far as i can understand wattman does not support profiles. so when i want to play a game i have to mess up the settings.
recently sapphire released TriXX Utility 6.0.0
http://www.sapphiretech.com/catapage_tech.asp?cataid=291&lang=eng
which supports EVERY rx 480
and indeed it works AND supports profiles so i can easily change settings.
but don' t seem to find a equivalent set of settings for trixx. It allows for:
gpu clock, power limit, memory clock, gpu voltage (goes down to -200mv but starting from what?) and fan control.
can anyone help me archieve same settings 50 watt power draw using trixx which supports saving profiles?

i think there is something with this card .. why after market coolers taking so long is the power issue is the problem ? companies are afraid cards will fail or what 

Great job!! Do you have "your well-tried settings" for zcash as well?

I tried it on my rig for my 2 480 it is great thanks. Anyidea do down voltage 470 and 570  I have 2 470  on rig making 27.5 at 70w and 2 570 making 28 on 90w (570 is terrible)

Great thread! Thank you! Amazing results. I'm brand new to mining, so I haven't yet decided to take the leap and flash my bios. I'm no newb when it comes to computers, but at the same time after such a big investment in several machines, the last thing I need to do is make one mistake and brick several cards. At least not until I get my ROI - At that point, I'll probably give it a try.

Right now I have my stock MSI RX580 at 1230 / 2050 with 910 on core and 920 on memory. I'm doing Zcash and pulling between 305-320. I'm going to try to do some more fine tweaking - do some memory tests and make sure that the card is doing it error free. Fan speed is 30-40% and temps aren't getting higher than 70. They hover between 60-65.

I'm probably about 125 a card. Though, I'd like to get it just a little lower, but still stay at roughly 300.

Hi!
I'm following this thread because is full of great and useful informations and advices.

I've found this video on yt: https://www.youtube.com/watch?v=Mwb67g4skGM
He is flashing the RX 480 with the same bios, but modifying just the last state (I think).

My question is: could this be achieved also on a 4Gb RX 480?
Would this be the same procedure as modifying these values in Wattman?

Thanks

My MSI RX480 4G runs Dagger Hashimoto at ~21,7-22 MH/s at default MSI Afterburner settings with 143 W (GPU-Z). By reducing temp. limit to 60, core clock to ~800 MHz and fan speed to 25%, I get 21 MH/S with 77 W. I wonder is there a way to reach higher MHs with this card? To my understanding suggested Wattman efficiency settings can only decrease MHs?
