470 4gb Nitro with elpida after edit in hex 28.5mhs.
1100/2000 -100mV
1100/2000 -100mV
That is very fast. So there is little incentive to buy the 480x any more. That will not be more than 20% faster.

Can anoyone explain this:
It should be the Elpida. After that the miner crashed, couldnt close the claymore miner window and when i wanted to restart system it hanged at the point where it should boot up, wouldnt reboot. Switched the psu power button off and on and then it started fine no problems at all.

Did you get a OpenGL call in the log files of claymore? The over clock might be to hard on that card.
Also when a gpu crashes like that it could lock up the system hard reset only way to get it back

Getting to 71 W is not impossible but achievable by Trixx and WattTool- that's what I used - just adjust the GPU voltage slider while watching GPU-Z GPU Load, Memory controller load and GPU Power Draw. If PC froze on you, or memory controller load just droppeed , you hit the limit, so tweak accordingly
In fact you can go under 70W if you underclock more, but I set my target to 28 Mh/s with reasonable power draw.
Last, remember evey card is different from the other, even they are same brand/model/lot, so some may require less/more voltage .

how much the percentage you undervolt ? -25% ? my hashsrate only can reach 22mhs at 70watt powerdraw gpu z :/
DAMN THAT'S VERY LOW POWER DRAW.
can you share your rom ?
currectly im running rx 470 4gb at 28mhs+300mhs sia coin, i have polor and saphire too.
I dont remember my setting much ... will look it up on my logs and get back to you ... i had it running 390watt for 4 cards + mobo off the wall. Funny thing is that I am living in the tropics and weather are at constant 31 - 33 C at day time with mid humidity and this rig was not hot in anyway even its not in any AC enviroment.

been running few days without any issue... why you not share your rom ?
Might as well post my results:
4x Sapphire RX470 8GB. 28.5Mh/s each, 530W @ Wall. I'm guessing the system is at around 60, so 470W for the 4 cards, or 115-120W/card. Took me a while to reach this very stable and low power setup...

Hi guys, I am trying 4 days already to make my Asus rx470 rig working.
Rig configuration is following:
Intel G1840,
Asrock H81 Btc Pro,
6 x Asus Strix rx470,
LC Power 1200 V.2.4 Platinum,
8gb ddr3 HyperX 1866,
PCIe extenders with molex.
I succeed to make single card to hash between 25-26mhs, but whole rig (6 cards) is totaly unstable with any configuration I tried. I used Polaris Bios editor to change bios,I copied values from 1425,1500, 1625 strings to columns above. But cards not working stable. I tried different drivers,OS is win 10 Professional, 64 bit, Dual miner - Claymore. For changing memory and gpu core settings i used WattTool, tried with some suggested settings for different rx470 models with Hynix memory from this thread, but without success.
If someone made Asus Rx470 rig working good, please left configuration here or send it to PM.
Thanks in advance.

I have the same problem, I change the BIOS in the first card and everything is running cool, but when I try the second one everything goes to hell, is not stable at all.
My best result so far
ETH only
Sapphire Nitro RX470 4GB x 6
Each Card 25.4MH
Whole Rig 152MH
Power Draw is 640W on the wall
Running for weeks

been running few days without any issue... you have been running a few days without any issue yet its the same picture from 7 days ago with only 2 mins run time.....
let be honest... it isnt stable enough to post...

the power consumption on the R470 makes it better
I'm getting 25-27 mh/s stable on the 4GB RX 470s using modded BIOS. Could get a bit more out of them but its nice to not have to worry about rigs crashing while I am away - negating the small bump in hashrate.
The 8GB models are 28-29 mh/s - stable.
These speeds are running Claymore's dual ETH miner with DCR (-dcri 30, just leaving it stock).

same with my two 470 and a mix of 3 other cards,Im slowly replacing . it's very stable and overclocked from the bios , i think im gonna leave it how it is, both 470 @ 27.892 mh or higher without using Afterburner, and no crashing in the last 2 days after modding the bios and i have no problem with using third party software, if needed.

Two things:
First 470's seem to have a hardlock on 2100 Mhz RAM -my Nitro cards behave like they could blast through that limit with ease.
Does anyone know how to remove the 2100 Mhz limit?
Well, there is a 2100 limit in the bios that can be changed with PBE for the cards that do not have Elpida memory.
Could someone give some details about Sapphire nitro+ 4gb Elpida memory ?
That one is not supported by Polaris Bios Editor and i am not able to fix che checksum necessary to change timings.

if you could do it by editing the hex then flash with -f option.(force)
