28MH @80 watts at the wall per card  I can get these suckers to go up to 29-30mh but this is rock solid stable and sips on power...run super cool at mid 50's with low fans. Took alot of bios modding but finally these Polaris dies are living up to expectations.  |

Where the GPU fault errors fixed in recent versions of this miner for Polaris cards running the AMDGPU Pro drivers on linux...or anyone figure out whats causing them? The miner runs but these messages are spit out at like 1000/s which degrades performance and eventually fills up the dmesg log/drive with gigabytes of log files. [ 422.094330] VM fault (0x01, vmid 4) at page 135290878, read from 'TC7' (0x54433700) (132)

Here is what I have the 470s up too (impressive little cards). This is completely custom bios, and had to hack the shit out of the amdgpu pro drivers on linux to get it to work properly.  Nice! I have mine to over 27MH/s (4GB) - you just edged mine out. How long is it stable, though? You can see mine here has been going for a while (NSFW): https://ottrbutt.com/miner/ethwolf-470-08172016.pngMy 6 cards havent crashed yet...but I have auto-reboot scripts anyway even if they do  Mine does about the same with the stock kernel so speedup is probably just because of claymors slightly faster kernel. |

Definitely not doable under Windows.

The Rx480 4gb was suppose to be $200 USD. Highly doubt we will get the Rx470 for under $200 USD>
$200 is only for reference, and we won't see it in huge amounts because it's a locked 8GB version. True aftermarket 4GB RX 480 will cost $220-230. The pricing for RX 470 is ridiculous now, the logic of sellers must be "it's as fast as RX 480 so it will cost the same". Yea they are taking all the shitty 480 dies that didn't make the cut, repacking them into a 470 with crappier components/memory and charging the same cost....ridiculous. |

Any updates?
Long story short, they sold out their current wafer run before I could ink a deal. I gave the chips to another prominent hardware dev on here  Hopefully something can materialize from this chip for their next batch. Meanwhile I will hopefully have something fun on the scrypt side of things with the new A4. |

Amph, you know what .... i dont care
See what you get when you do shit for free? Motherfuckers act like they're entitled to not just your work, but your time. They do not value it. he didn't do it for free he was payed already and do we really need to pay each time we ask about a little help here and there? this place is fucked with greedy people for sure Funny. You calling me greedy, when you pay nothing and get pissy when developers - who put in more time and effort than you probably have in life acquiring the skills - don't do what you want, when you want. But I'm greedy. Okay. i was talking in general not directly to you, i just find it absurd that everyone need to donate just to have little help Being a developer myself and having done many free and paid projects for people around here and litecoin, I think the issue is that this "help" is generating you income...why wouldn't you pay for it? Im not directing this at you per say, but I don't think the devs are the ones that are greedy, but everyone else that is making money off our work, and get very little in return, especially when we help out the community and put our stuff out there for free. Of course there are greedy devs too, especially the ones that use their skills to scam people, but thats another discussion. I think people would get a lot more out of things if more people donated to stuff that people put out for free, and they would be more inclined to fix/improve stuff instead of not caring. |

Where are the settings for 29@ 120 watts?
Here...if you look closely you can make out the proper Hex values for the bios squeezed a few more MH out if it with some BIOS hacks  |
|
|
|
Yeah in linux you can run any type of bios, while in windows if you try to run those modified bios's it will just crash on startup.
jstefanop, how much in total from wall ?
120 watts at the wall for one card...180 total system power. |
|
|
|
never said anything about running crap windows  squeezed a few more MH out if it with some BIOS hacks |
|
|
|

Yep...running custom BIOS on ubuntu 16.04..29MH @ 120 watts.
|
|
|

elpida+380x pulls over 21.5mh/s
23mh/s with bios mod
What bios mod, do u have a link? 380's pull same amount...my BIOS does about 21 MH @ 110w |
|

Well if thats the case then your better off buying $200 worth of eth Even if it doubles back to $20 in 2-3 months...diff will have doubled by then as well so even more reason to buy coin instead of GPUs. |
|
|
|
Someone that is gonna buy this GPU is from EU ?
In my opinion even with 30Mhash/120W with european prices it's difficult to ROI.
Yea its definitely not worth it...at the rate diff is going up even at $200 you'll be lucky to ROI. The days of crazy ETH mining profits are over. |

FYI you can down clock the GPU core to around 1160-1180mhz...the GPU waits on the memory controller after those speeds so no point running it full speed. Saves a few watts.
on claymore miner i jumped my hash rate from 50mh to 54 mh by moving clock from 2000 (stock) to 2200 this is for the 480x not the r9 390's GPU clock not mem clock :p |

I have fans set to 60% and temps are around 70c....its undervolted as well and pulling around 120 watts at the wall. Im still working on it, hopefully I can pull over 30MH from them. BTW this ONLY works with linux.
That is very low power consumption for the whole system. How did you undervolt? Do you modifiy the BIOS? I wish it was the whole system...its 120 watts at the wall for the card alone. |
