Before i change roms i made another check. http://i68.tinypic.com/2ugi8b5.jpg GPU-Z showing under 100w powerdraw per gpu but the total consumption for four cards + system is around 738w from the wall.
738w - system 75w = 663w / 4 = 165w per gpu
Can someone confirm that their 480s @ 30Mhs pulling 100w from the wall measured with a killawatt ?
I was supposed to try it out today. But if you check my picture gpu-z is telling me that my cards are pulling under 100w each but the real powerdraw is 165w when i meassure with a wattmeter.
edit. will try it out on one rig first, will get back with the result.
70W gpuz, 100-105 on the wall 29mh. 60% fans(2350rpm), 64-65c temp
Why not dual mine? it's like 7.5w or so more in gpuz... I thought the extra profit from sia would pay for the extra watts but maybe it only equals out now..?
Ok. Now running the "low-pwr-29MH-Boysie" roms in one of my rigs. Powerdraw at the wall: 680w for the whole rig (4 cards) Still over 150w per gpu from the wall
As long as no one shares a rom with real voltage offsets in the rom, there won't be a decent one. And no ones going to share that as only a few know how to do that and they're not active here.
PolarisBiosEditor is fine, but it's a toy.
Will have a rom with voltage offsets done this week for sure. However not going to share it for free. Sorry.

Hold on what exactly do you mean?
Do you mean that either 1. Roms can't be decent because you have to still lower voltages in wattman or 2. That even if I lower my voltage in wattman, you can do some special thing in the rom to make it MORE efficient at the same voltage I could set it in wattman?

You need to go in wattman or watttool and lower the voltages on mem and core to 890 as it is in the rom if you open it with the bios editor. Just flashing a rom is doing nothing because the driver is setting the voltages on auto, you need to see what is se it the rom and then manually apply them through wattman or watttool.
Basically the same as what i did with my nano roms..
Will leave some more info when i'm at the office, on my phone right now.
Sure, I am not familiar with what you did with nano roms
What i do exactly is this.
I do an i2c register dump, after that i do an AIDA dump which will tell me what the gpu needs in case of voltages at a certain clock.
After that i modify the rom to have VDDC, MVDDC(if possible) and VDDCI/AUX offsets.
In other words: so that i'm able to tell the voltage controller to start delivering voltages at a lower start.
So if it calculates your VID for a specific DPM, it auto deducts -100mV (because it already started calculating from -100mV than what it usually did. Thus making the gpu more energy friendly and in a lot of cases a shitload more stable in case of throttling.

Ah ok. I got gpu errors trying to run the bios on several of my gpus so i tried to switch back to the one i had before. Now i get gpu errors on that rom too. I will try to sort it out when i get back home after work today.
every 3 hrs maybe? if yes, PSU or your breaker. try to connect the rig directly to the wall, no breaker in between. if the problem persists, its your PSU. i had a platimax 1350 and needed to switch it to a single rail PSU. mutlirail seems to suck to mining. single rails being overloaded.
I'm running two rigs with 6 x RX480 on Linux/ethOS and I seem to consistently have a problem with GPUs crashing. I used the low energy rom from Heliox and that helped stabilise the GPUs hugely but I'm still experiencing issues. The weird thing is that it always is the 2nd, 4th and 6th GPU that crashes. I have tried changing mobo which actually also helped but didn't cure it. I'm not sure if it is because of the drivers that are not very suited for linux (I know that ethOS is using a back ported driver as it runs Linux 14.04) or if there is something else I'm not thinking of.

Actualy I figured that it was BSOD when it crashed. Sometimes it crash after 5 hours, sometimes after 20 hours.. I checked the minidump file and I found this:
Anyone know what could be the problem? I'm using Crimson Edition 16.8.3 Hotfix drivers.
@boysie sorry for this question that maybe you have receive, there is actually some permanete drive signature procedure for ati driver on windows 10 or I have to follow the steps describe every time I reboot the machine ? Can I use the last 16.8.3 driver or I have to use the old one in order to override the signature check ? your bios modded works on XFX RX470 4GB black ? Thanks again

480 only not 470s
16.8.3 is fine.
yes you need to self sig the modded driver and run windows in test mode...lots of threads about how to get there working...

Thanks, I've read the steps but I'm lost, I don't understand if each time I reboot the machine I have to redo the signature procedure on windows 10.
Anyone can tell what is the watt consumption of 6x Sapphire Radeon RX 480 NITRO+ OC 8GB DDR5 256-bit Lite ? I am about to make the rig this days but i am not really sure about the psu.. 1300w is ok?

I got 5 of these exact cards running on a 1000watt psu with my watt meter says 750watt usage. Still waiting for a custom rom...

60-100 more coming! Really need that custom rom. The 27,5 mhash on 80 watt is very nice, but they can do a lot better! Cooling is just awesome, i got temp's from 50 to 55 C.
