To community:
It looks like my rig is super unoptimized
I have
3x RX 480 Sapphire Nitro+ 8GB
2x XFX RX 480 8Gb references
1x MSI RX 480 8Gb
My total hash rate is ~148MHs (ETH only, CDM)
Wattage from the wall: 1200W
All stock values no OC, flashing etc. Win 10, last drivers
Any ideas?

Do you at least turn down the power by 15 to 25℅? That should help. What is your power as reported by GPUz per card?

UPD. 1 - I tried. This card hash dropped from 24.8 to 4.22MHs. And is not going back - have to restart UPD. 2 I've undervolted all of them by -50mV and now getting 1130W UPD. 3 Tried to increase mem clock from 2000 to 2100MHz - system crashed |

Well, I continue to try and tweak my clock speed and voltage settings on my 4 RX 470 rig. At last check, I had finally got all 4 cards up slightly from 20.75 to 21.45 Mh/s by setting clock speed to 1700 (max amount in my Wattman for some reason...Afterburner allows all the way up to 2100 so not sure why the disconnect). Unfortunately, this increased my wattage at the wall to ~730-740 (from ~625 before the tweak). Obviously, this was a net negative trade-off, so I went back in and tweaked some things a bit earlier today.
First thing I did was reset everything on all 4 cards. I wanted to get back my power savings first and then start to mess with clock speeds. Looking only at the GPU mV by state, I first took a crack at lowering state 4-7 of my 2 hungrier cards. For what ever reason, these 2 suck like 15% more power across the board than the other 2, so I chopped them down a bit. Unfortunately, I must have lowered it too much as 1 of the cards crashed, then my system crashed and rebooted. So, I dialed back the reductions a bit, as well as lowering the other 2 cards. This time all 4 cards were stable and I was actually showing a bit lower total wattage than my original low at about 615.
From here, I upped the clock-speed to 1700 on only 1 GPU to test the result. The HR did go back up to 21.45 and surprisingly, Afterburner was showing almost no increase in wattage pull! BUT... when I checked my kilawatt, the wattage had jumped up about 50W! So... 2 questions here:
1: is a 50W bump for only a measly 1650 to 1700 over-clock reasonable? I never OC'd before but this seems high for such a nominal increase
2: why would Afterburner still show the wattage on this card at around 74 both before and after the OC, but my overall wattage pull increased by 50 at the wall? Does this sound "normal" or is there possible something wrong elsewhere in my system?
I also did some benchmarking on other system resources finally. At boot up with nothing running (except windows of course), I am at 95W (not including monitor that is not plugged into my Kilawatt unit). Then I launched MinerGate, that I have 7 cores of CPU mining XMR. This added about 45W. That CPU is hashing about 260 on XMR so that's a semi-decent side-profit of about $10/month lol.

Alright, I got 6 full cards hashing at stock at the moment. (not for a long time, last time it took 10 mins to crash) After uninstalling and reinstall amd driver a lots, I downloaded their cleanup utility. I manually removed all rx470 from the device manager with driver's delete option. Launched the cleanup and rebooted, launched the clean again and rebooted. Downloaded the latest driver, I always used 16.9.2, installed the 16.10.1 drivers. Rebooted. I'm going to bed, but it looks good ! Thanks to everyone for all the inputs. Hoping I can OC them a bit tomorrow  EDIT: And GPU hangs in OpenCL call, exit... It tried to restart but it's not working I get those from time to time too. Mostly now when. I updated to claymore 7.0 and above Not saying it is calymore but I see it more with 7.0 or newer Great infos ! Thanks you. What's your frequency ? I run 1500 strap with 1130core and 1945 mem all modded bios I make 1 more setting change for my MSI RX 470 Gaming X: Start WattTool - Set Voltage offset to "-15" and click set for each card. This will decrease your overall watts TREMENDOUSLY; therefore, reduce cost! This will make you smile.  Hey Aries... I've been studying your posts in the hopes of at least partially re-creating the power/watt ratio you've been able to achieve on your 6x470 rig and was hoping you might be able to answer a few questions for me  1- You are using MSI RX 470 4GB, correct? Or, are you using the 8GB version? 2- When you say "1500 strap", what are you referring to? I googled it but couldn't find anything that made sense 3- I looked up WattToll and will download it on my rig later, but had a question about the command you used "set Voltage Offsett to -15". I see this field at the lower right of the WattToll window (shows "0 x 6.25mV" where user can over-write the "0"). Just to confirm, you simply enter "-15" in this field and click Set? Thanks! |

Anyone here use sapphire Trixx?
If so how do you get it to load a profile for all gpus

Replace the "0" with -15. |

Thank Lone & Aries! I saw a bit of the video last week but watched all last night and it seems pretty straight forward and even made sense for a noob like me lol. I will be taking a crack at doing both the strapping and power reduction on 1 card today as a test and see how it goes.

let us know mh and watts watts for 140mh should be 950- 1000-1050
Phil, I used AfterBurner. Started from all stock parameter incrementally decreased voltage on all 6 cards to -65mV Now I have 148 Mhs with 1015W from the wall
Is it good number? |

Is it good number?Yes you are close to 25 mh per card 24.9 or so and,you are lower then 7 watts an mh say 6.85 It is possible to get to 6 watts but titanium psu 240 volts and all really good chips in the One rig I have touches 590 watts 101 mh but mostly does 610 watts and 98 mh. I have four card rigs titanium psu 240 volts. |

I wish I had 240v. If only we didn't need that pesky dryer....
I suppose I could convert two 120s into a 240 circuit in my basement. Has anyone done so? Just seems like a lot of hassle.

Thank you Phil! I'm renting a home - and have no idea do I have 240V socket or not. It was super easy in EU  |

It is possible to do,so. A lot depends what is in the circuit box. I did two in my house. But they were dedicated lines. In the first place. I did a show n tell but it will take a day to find the thread. I can provide two thirty amp 240 circuits which is about 12 kwatts once you derate by 20 %. Not ever happening as the house would be too hot and too loud. 2 kwatts summer 4 kwatts winter pretty easy to handle heat wise. |

That would be fairly easy to do if you understand electricity but change out the receptacle to a 240v rated receptacle. You need to make positive that the receptacle you plan on switching over to 240 has a DIRECT LINE to the circuit breaker and is not daisy chained to other receptacles. All you need is room in the panel for a 240v 2 pole dual ganged breaker. Make sure to wrap the white wire in electrical tape as required by electrical code, here is a simple pic I drew http://i67.tinypic.com/2wrnqm8.jpg |

You cannot do that. In order to get 240 from 120 V, you need a transformer to do that. That will consumes energy as well. |

I just figure out how to get more out of my system!!! Overview: -total system hashing = 169.6mh -each gpu hashing = 28.3mh -ave card wattage = 67W -total system Watts = 831W (At the Wall) -total system Amps = 6.91A (At the Wall) Efficiency per Card = W/Mhs = 67/28.3 =2.37 (Less is better) Efficiency per system = W/Mhs = 831/169.6 = 4.90 (Less is better)  |
