So many more factors to include in this.
You've got PSU efficiency, type of gpu, the way the rom is modded (power draw from the pcie cable or the slot (it makes a difference!)), the risers also pull some power, not every cpu is even efficient, same goes for the memory, etc...
According to WattTool topic starting post on overclock.net the most efficient mode is the default - when a lot of power is going from pci-e slot. Is it right? Well, i will have a detailed answer for that either tomorrow or the day after as i'm testing that  Even if it's only a few watt saved. Less power is less power  So at this moment, i cannot really answer that |

930w from the wall.
System : ~75w
=
855w
Split that on six gpus: ~142.5w per gpu from the wall @30Mhs
Still really good numbers. People should stop staring at gpu-z numbers because they are pretty much irrelevant.
The wattage presented in gpu-z is what the gpu itself are pulling, not the whole card.
The GPUZ number is 69W, the actual power consumption is 142W from the wall, or 125W for the card, so the difference is about 55W. So many more factors to include in this.

Last news: Got a decent offer from someone, i replied to his pm, haven't got a reply back.. So still for sale Greetings! |

It's a custom job. So in other words, not really public Greetings. |

I've done some more testing, trying different xI and rI values, and can say the following:
1) Hawaii performance is great; as good or better than Claymore & Genoil.
2) Tonga performance is about the same as Claymore & Genoil.
3) Pitcairn performance sucks; ~10% slower than Claymore & Genoil.
@Wolf0, any plans to tune this up for Pitcairn?
What are your work size, thread concurrency, intensity values for the R9390? What is your 390 setting? Where did I say I have an R9 390? You mentioned Hawaii cards. There are only two Hawaii cards, the R9 390 or the 390X graphics cards. You forgot the 290, 290x, 295x2(Dual Hawaii "Vesuvius") |

eliovp aka heliox.... I am still ROI-ing my Nanos.... and wondering if you can do a lowpower29Mhs rom for it. The power bill is still killing me. Thanks
What are you running right now? in other words, vddc = at minus how much? -115 is the only that worked. 150 worked for awhile but unstable. Well, just go for a -100 or -94 vddc offset and raise that core. Keep your memory at around 290 and you'll be ok. (HBM memory works in 20Mh steps, just so you know ). Here, because i had nothing else to do :p (haha) Tighter timings, both vddc and mvddc -100mV Try to play around with core and memory clock. I'm sure you'll find something very interesting Greetings!

ohGodAGirl- I did not mean to offend you.
Here are some settings that have been useful for me on 390/290's
Worksize- 256 runs well at xI of 190
Worksize of 192 works well at xI of 167-170
Those are on 1100/1250 clocks
You didn't mate! Don't stress. Just want to make sure folks understand that one or two HWs are normal and to be expected. Thank you for sharing the settings! After one hour hashing,I have 50 hardware errors in one card. If I increase the xintensity from 256 to 1024, there will be hundreds in one hour. Maybe stop using xintensity.. :p I tried your rawintensity value, similar results. Your raw intensity is similar to xI = 2048. How many HW do you get in one hour mining for your R9 390? After 8 days, non stop, 11620 hw errors :p (but still running smooth) |

Hey I already had a nitro rom for 380 Shared it with a few people privately. They're all very happy with it Getting 23.5Mh out of it Will share it later. Got a rom for 370 cards as well. yum yum.... 370? Can you send me download link for 370 and also 370 Nitro? Yups. Should be compatible with these cards (4GB!). (tested on a 370 nitro and MSI 370 4G) ASUS STRIX R7 370 DirectCU II GIGABYTE R7 370 WindForce 2X OC HIS R7 370 IceQ X2 OC MSI R7 370 Gaming MSI R7 370 OC PowerColor PCS+ R7 370 Sapphire Dual-X R7 370 Sapphire Nitro R7 370 XFX R7 370 XFX R7 370 Double Dissipation XFX R7 370 Double Dissipation Black Link: HereBest results (only tested a few hours): core: 1080, mem 1650. Was thinking about creating seperate threads but haven't found the time for that. Greetings! this link is 404，Can give a new one plz Yeah, i took it down. Maybe, maybe i'll put it back up.. |

Edit: Forgot to mention, currently working on shedding rops, will "hopefully" have a working result by the end of this week @Eliovp Any luck diabling ROPs? I'm curious how much power it would save. I never came across any info on how much of the power saving of the Stilt BIOSes was from ROP shedding vs under-volting. Will have some more time to continue my work on this next week. how about to mod bios so 280x can give at least 20MH?
20Mh = not possible. 18+ is perfectly possible but to give a comparison. If you run at 16ish and you mod your rom to do 18+ which will give you "as an example" + 25% hash increase, your power usage will go up like 30%.. so is it worth it? Nah.. |

Just wanted to push some updates in this thread. Had a few offers, one that was rather large. in the end they didn't came through (as i kind of suspected :p). So in other words. Still for sale Latest analytics info.  Greetings! |

How do you keep them cool? Mine are close like that and have a tough time with temps.
Heavily underclocked |

i have 100 Nitro's running and i turned on the led indication color for the heath of the PCB Board
Checked my power meter and it was at 10.43kW, i turned them all off and i checked again. 10.42kW.
So i put them back on :p
100? Nice, pretty great amount, wish I had that much too to mine with.  Single GPU carrying LED light doesn't take more than a watt. I'd never suggest you to turn it off since it looks pretty beautiful than the money saved with a watt. Haha, it's kind of handy as well, they change when the pcb gets to hot. So at this moment, they're all blue (which is good) as soon as they turn red, i know something is going on Here's a picture:  Greetings! |

flashed RX480-30MhOTB on my 2 units of XFX RX480 8gb Reference, it does run up to 30Mh/s however it wasn't that consistent (dropping down to 23-27 most of the time), is there something else i should look at from Radeon software tweak?
Do your XFX cards have backplates? I tried flashing the LowEnergyOK ROM onto my (reference?) XFX cards (w/ backplates) and was unable to. Yes, but its not the black oc edition... Just an update, so far i reflashed back the card, open the radeon software, set the voltage to 920 and others as manual, the rate is consistent between 28-30Mh after resetting my PC due to low hashrate along the way, the hashrate now went back to inconsistent 23-27 ... why is that happening anyway? :/ Could be a few things. Memory to tight. Memory clock to high, you can check this easiest if you open up Afterburner and check if the Frame buffer is over 95% "consistant". Could also be that the TDP limit in the rom is to low. So it's bottlenecking there. Could also be a temperature issue. Could be a lot of things :p |

@Eliovp I still wait your test with 2100 mhz - 1500 strap.
@All VDDC can easily drop with Msi Afterburner. Just edit your bios for gpu frequency, ram frequency and also for ram straps. TDP and VDDC can tune with Msi Afterburner.
Don't consider the idiots who drop the VDDC and give no information. They behave as if they are Mandrake.
1500 strap all the way up, frame buffer will drop, as so will hashrate. I only have Samsung cards and a Micron card to test with, perhaps on hynix this will work, i can't say. Still, i doubt it Btw, your pictures are unclear, like always. No clear info. have you ever done anything for the community? Nope i don't think so. A lot of words. But nothing to show for. Adding VDDC Offset will let the voltage controller start calculating the needed voltage for a specific DPM at a lower start. Therefor it is better to do it like this. You have lots to learn young padowan :p is there a 470 that doesnt have hynix? Hey, I have an MSI 470 Gaming 8G with Micron <-- yeah i know.. sucks and also have a Sapphire 470 Nitro 8G with Samsung mem. Greetings sry I meant 4G, do you use 1500 straps on the MSI 8g & 4g(assuming you were to use polaris bios editor) even though its clocked lower? The MSI one can't handle anything. Clocks higher than 1750 is a failure.. I think i'm going to donate that card to charity.. The Sapphire one can take it all though :p |

Those strix cards have mvddc control which makes them unique and very interesting! :-) In other words, adding an mvddc offset is possible for these Yeah, but you gotta put it in yourself. No easy GUI tool there. Exactly, already done it on the reference and on my nitro's (vddci for these models ) |
