My sapphire Rx 470 4GB Nitro have elpida memory, and I have problem with polaris bios editor.

Any help? I can’t change strap

Good thing Smiley

And it's not because it's Elpida, it has another reason.

My MSI rx480 4gb

eth 30mhs
sc 450mhs

set -ethi 12

Sure not stable. Or high speed in miner but less shares due to memory errors.

sapphire rx 480 nitro+ OC
is not suitable for dual mining?
eth mining 27.5mh
dual mining eth hash rate drop to 24mh

it is normal or just, vbios not configured correctly for dualmining?

Do the same for your card

No go
its only slower

send me your original bios file, I will edit it your or see https://forum.ethereum.org/discussion/9650/sapphire-rx-480-nitro-oc-8gb-11260-01-20g-modded-bios-29-mh-downvolt


claymore miner last version 7.4 i think it is... eth only 27.6mh
eth+dcr 22-24mh on eth ?!?!?!?!?!
but one think.... this is only test pc with core 2 duo, 6gb ddr2 and pcie 2.0 runing ubuntu 16 700W psu
its possible to "my" vbios settings, it wil mine just fine on asrock btc pro 16gb ddr3 ??

Thanks for the replays to the guys posting up on watts used in terms of each modded bios gives me more to go off.. Just another question for the modded people are you guys using the reference cards or others?. Will these modded bios be good for Sapphire, MSI ausu cards as been looking into some of the MSI and the clocks are very close to some of settings people adjusted to? What would you guys recommend in terms of of ones to grab MSI, Asus, or sapphire?

I would like to thank custom work XFX RX480 non-reference GPU's modded BIOS by Eliovp (Heliox)

6X GPU 182Mh/s, 63watt/gpu GPUz and stable more than 1 week (continuous operation 0-24)

So perfect job and perfect finish!!!

Thank you Eliovp  Smiley


wow - this is great results!

which rom did you use from Heliox?

Impressive 182MHs under 1000watts

He did not say 63watt/gp from the wall. It is from the gpuz. So the total wattage could be more than 1000W from the wall.

I think it is understandable:

http://i65.tinypic.com/2rcu93k.jpg
http://i68.tinypic.com/1z73fc6.jpg

impressive!

Here, other's can maybe freely achieve this too.

Finally had some time to play around with my 480's again, and after playing around with WattTool, I am pleased with the results and here to share. Been going stable for a day now with the 29 lower power rom and tweaking out my WattTool manually. Seems like I get better success underclocking with the voltage offset than manually overclocking the voltages for each state, so I made them all flatline and let the voltage offset do the work.

See photo for my settings, can't complain for 65w on GPU-Z and 0.8750 VDDC.

Note: If these settings crashes your computer, then keep increasing the Voltage Offset by +1. So if -10 is too aggressive for your 480 cards, then next test with -9, then -8, and etc. until yours is stable.

Word of warning for those who are planning to purchase branded systems, specially Dell or HP workstations, specially Xeon processor. My only 3 GPU's (RX 480) are consuming like ~70 Watts each according to the GPU-Z, of course that it's not the right number if we take the wattage of the whole GPU, but still let's consider like 150 Watts for the whole card, providing me 27 Mh/s, haven't done very much overclocking, just a bit.

The system is consuming 400 Watts when not mining (in idle condition), and 800 Watts when mining. Meaning that GPU's are taking only 400 Watts and the remaining 400 Watts is being used by my Dell Precision T7500. Angry I'd not never suggest anyone to buy branded system, instead, build one. That should save lot's of power.

Please keep in mind that efficiency of PSU is also important. If your PSU is not efficient it might pull more from the wall than others. I do not think that HP/Dell put highly efficient PSUs into their Workstations.

No, it's not the PSU. It's Silver 80+... overall 1100 Watts supply. I did put in first my Corsair 750 Watts Bronze (CX750M), and it was using all 750 Watts during mining, so I put it off as I hadn't seen any difference in efficiency... The workstations eat the power like beasts.
