my MSI runs with 1100 MHz@-60mV nonstop since two weeks. Good compromise between power consumption and mining power.
Also overclocked HBM memory temporary to 525 MHz, but this seems to have no effect to MH/s, so I lowered it to 500 MHz again.
Anyway, R9 Nanos are amazing cards! Cool

The HBM is already fast enough. The bottleneck is in the GPU core. That is similar to the R9 390 series.

@Termie Can you say a little more about mining results using that settings? Power consumption, noise, hashpower, etc.

Awesome! Your mod is going to my "to do list". What OS are you running? win10?
Thanks

Yes i am.

Also tested on ubuntu and works perfectly as well.

Have fun!

Very nice results, i am impressed with your modification. Did you tested stability under other circumstances than ethereum mining? For example other Dagger coin (Soil or Shift)? What about other, more energy consuming algos (DCR), are they also stable with modded bios?

Hey,


Yeah i have tested other algo's as well.

They all work perfect with my bios.

The only difference is power usage. Which is obvious. Smiley

thank you eliovp, unfortunately it's not working.. still ..

I'll go to bed but I'll try to check it when I have some spare time.

Thank you


Have a good night/day

We will sorten things out. Get on IRC and we'll talk about your issues and try to solve them.

I'm off now though. We'll talk later!

Great success.

I have some problems with the driver crashing.

Using windows 7 64 SP1 with Radeon 15.12 drivers.

It usualy crash when i press the start menu or file explorer etc, but if i get the mining started its stable until i cancel the program. then it crashes and hangs the computer.

Strange Smiley

EDIT: Fixed with disabling Aero..

Haha, you were quicker than me.

I know it happens, had it too. Further it should run smoothly.

Have fun!!

Will you share the latest modded rom that is stable?

The main link isnt working anymore either.


Not yet sure about the latest one. Still testing to get it perfectly stable.


The Nanomod.zip link in your OP doesn't seem to work?


Link is fixed!

Click it again Smiley

Thanks!

hi eliovp

at first, congrats for the nice achievement

It must be said that the nano it's very interesting regarding the power requirements, especially with the stock downvolt capability.

Considering the measurements in W as the PEAK values, and the Speed in MH/GH as the minimum ones (average ones a 10% more), I managed to let it work:

ETH - dagger hashimoto: from 88.5W(16.5MH) to 232W(26.5)
DCR - blake256 8: from 202.25W (1,980GH), and higher than 217.25W (2,264GH)
X11 - no more than 7.1MH on nicehash 5.1.0, where it's reported at 20MH (WIN 10 Pro 64 bit and WIN 8.1 Ultimate 64 bit)

Have you made tests in regard (X11 nicehash)?

About power consumption of R9 390 and Fury/FuryX, have you gathered any reliable, real, information?

An R9 290 will need at least 289W on X11(13.5MH) and the same amount with ETH(25)

Thank you



Hey Nikolaj

I managed to get that 88.5W you have there for Ethereum, to get the same, well even less power usage but @ 22-23Mh/s.
So you could go A LOT lower on power usage vs performance.

Regarding Blake, i haven't done any testing for Decred lately, only when it just came out.

X11, well to be honest, tried to run it earlier this day on a rig of mine. But Failed miserably, must be the drivers because i know i have done a test in the past with older drivers.

Here is a screenshot of that test
http://s29.postimg.org/a745dros7/X11.png

I did however manage to run Quark on a 6xNano rig.

here's the picture of that.
i included the config for that (X11 config is a bit different, i'll get you that as well)
https://drive.google.com/file/d/0B_cBBoZ_PTwOa2xjMXFQWktnYi1rQUh4SERpdWNmSllTV0I0

As you can see in that picture, only gpu 1 & 2 are doing what they need to do.
That is because of the miner. It's a hack, it works if you have less than 3 cards, but if you have more or 3 it starts to screw around.
As you can see in this picture, it screws around with 3 cards as well, Third card is doing it alright.
(this is also an older test with older drivers.)

Mm don't think i ever said that.

What i could have said is that you can lower the core clock voltage to a minimum of -100mV for Fiji.

You canNot change memory voltage with software. You can only do this with a hardmod. (Fiji and 3** series).

Have you mod the memory voltage of the R9 390 cards? If so, do you mind upload a bios file to share with us?

I haven't, sorry.

I could look into this later though.

Thanks in advance. If we can undervotage the R9 390, we may save 20W per card as we just need less than 1250MHz for Ethereum mining.
