R9 Nano mining results + power draw

[coins101]

Prices seem a little high, but the savings on power and cooling might make them worth the price?

[_javi_]

i´m planning on buying new gpus for mining..

but 650 usd for a Nano to get 25 Mh/s.. hmmm

long life my 7950/280x`s

Not worth it. You can buy a 7990 for $300 and undervolt and under clock it. You have higher efficiency and more mining hash.

True but you will have bought an old technology, old card, plus, i'm not so sure about your statement though.

His statement belies the fact that Southern Islands aka 7xxx and all their rebadges (R9 2xx/3xx) is still the best hash/watt/$$ you can get on the AMD side. 

The only new chips AMD has put out at a more efficient nm process are the Fury cards, and their mere cost alone removes them from hash/watt/$$ considerations.

they are still 0.28 nm: AMD just added some CUs and changed memory interface.

Thanks for the correction, i was imagining the Fiji chips at 22nm for some reason.  Still on the 28nm TSMC process i see.

I also am a bit surprised at the Nano / Fury / Fury X hash numbers.  Was expecting better.  Guess it goes to show that most algorithms are definitely not bandwidth limited these days.

Most algorithms are memory speed (frequency) or latency limited. For example, for Ethereum mining, there is no benefit of using HBM.

Evening.

I have done some testing the past few days with a Nano and i want to share my findings.


First picture is a picture of the power usage of the system without a gpu installed.

http://s29.postimg.org/6dcpvu1mf/nano_NOGPU.png
So 43watt when running idle (i7 processor with 32GB Ram, Win10Pro 64bit)


Next picture is a screenshot of the Nano running Ethereum.

Stock clocks (1000/500) @ 26Mhz average.

Power draw
http://s1.postimg.org/chsy3n2rj/nano_Ethereum.png
102 watt give or take for the Nano running Ethereum @ 26Mhz


Than we have a screenshot of the Nano running X11 (not the newest Nicehash optimized miner)
http://s4.postimg.org/9ayxqaotp/x11.png
Again Stock clocks @ 12Mhz average + not even playing with intensity, XI 1024 would have given me probably more.

Power draw
http://s23.postimg.org/nd2h9wckr/nano_X11.png
105 watt for the Nano @ X11


Next one is Quark, again, not the newest Nicehash optimized miner.
http://s10.postimg.org/68j3y2ufd/Quark.png
Stock clocks @ 16Mhz, a little disappointed here..

Power draw is almost identical to Ethereum power draw.


So my conclusion.

Best card i have ever had, Period!

There's no Nvidia card that can beat these numbers (yet).

Although, as mentioned before. It's an expensive card.
But worth every penny and it looks better too!  

Yeah, i'm an AMD Fanboy, i know :p

If there are questions or if someone wants to see another test, just ask.

Hello, I understand you're the resident r9 nano expert. I am new to nano and have it running in a rig at a consistent 78c degrees with the fan at 100% - my question is will this card survive or is there a max temp you'd recommend for 24 hour 7 days a week operation? Thank you in advance.

haha, i completely forgot about this thread :p

Funny to bring it up again, reading my posts i feel like a kid in a grown up world.


Anyhow, Nano's are reference models, they're designed to be able to run at such temperatures.
However, i wouldn't recommend it to have them running at or over 80 degrees for a long period of time.

What you should do is start with pulling that voltage down by 100mV, they can easily handle it.
That'll get your heat down significantly.

Greetings and success!

I will try that - thank you so much for your prompt response!

Hi Nano-Fan,

I know this is an old thread, but figuered I just use this one intead of creating a new one.
Mining ETH I get ~26 MH/s with the latest drivers from AMD.
I was wondering if higher hashrates are possible and if you (or anyone else with a R9 Nano) can recommend any drivers + tweaks for the Nanos?

Thanks,
KW

EDIT: I did some undervolting and slightly overclocking and managed to get 29 MH/s from the R9 Nanos! Anything else that can be tweaked?

[stoon]

Your at the max of the card on Eth/Etc. You may want to run it on Zcash/zcl. They get 400+h/s pretty easily. Or possibly dual mine with it.

Ok, thanks. Right now I am dual-mining DCR and ETH. I checked ZCash, with current prices ETH is slightly more profitable.
I wonder if there are any mining algos that make good use of the High Bandwidth Memory (HBM) of the Nanos?

[sikkan]

For a reference I run radeon 7990 cards and they certainly doesnt shine in Eth mining but when it comes to zcash its rather great.. Bought 3 7990s for under 300 USD 4 weeks ago. Downvolted to 1 volt and underclocked to 900 Mhz GPU. 560 sols/s and 260W per card.

For such old shite its pretty impressive I must say

That's pretty impressive. Well I got my new R9s for 360 EUR (a ~$400), they are dual mining right now @ 30 MH/s ETH and 900 DCR.

You may also want to R9 for the ZEC.

Can I see a screen? Can´t believe that 🙈

I run the cards at 800MHz and can get about 480H/s. So it is possible to get 560 around around 900MHz.

[pogsnet]

nice but i dont see definite answer. How much hashrate it can provide in modded state?
