Just thought I would share my benchmarking of the R9 nano.

All power measurements were done at the wall to be 100% accurate.
Benchmarks were done with: Claymore ETH - v7.4 (not dual mining) & Claymore ZEC - v8.0 (-i 4)

Stock:
1 gpu: ETH: 26.8 h/s Watts: 205w
1 gpu: ZEC: 272 h/s Watts: 200w

-100mV ROM
1 gpu: ETH: 22 h/s Watts: 103w
1 gpu: ZEC: 211 h/s Watts: 91w

-125mV ROM
1 gpu: ETH: 22 h/s Watts: 84w
1 gpu: ZEC: 217 h/s Watts: 90w

What an amazing piece of hardware, thank you for the mods.

It seems the the -25 mV extra memory undervolt just makes 1W difference. For my R9 nano, if I use -150 mV, they can run at 400 memory speed.

I only uvolted with AB 96mv( the most allowed), and get 1750H/s@1200W (6 gpus) from the wall. Even just using sw for uvolting its getting better results, any mem settigs just made it slower, so its 1000/500

I get 290ish w stock bios on V8, is there any better hr with modified ROMs?

with the -100mV ones, the Nanos runs lower power and less heat, but I managed only 260-280 H/s.

with the power savings, I dont mind with lower hash.

the Nanos are easily the best performer in my small farm, followed by 390s then.... then 480s.

@citronick are those the bioses with the 300 mv undervolt ? the ones that work for eth ? or are they different i cant find the rom you are talking about ? All my nanos
are stock around 270h/s but use a ton of power even after 100mv undervolt

-100mV ROM mods from Heliox - I got good power savings less heat too when mining Zcash and Monero.

With HBM 8GB and more compute cores, most of my Nanos are super performing currently at zcash.flypool

At stock settings without mods, Nanos uses far lower power compared to 390s but with -100mV I can achieve a good 30ish more watts savings below TDP 150w. Unfortunately, I could get past -100mV ROMs.... a few managed the -150mV ROMs but crashed after an hour. So I decided to just use -100mV version for all my Nanos.

When mining ETH, with Claymore 7.4, power and heat will increase up to 20-30%.

Btw, 16.7.2 seems to be good for Nanos.... however, I have one Nano rig with latest Crimson installed recently... and I couldnt tell the difference.... anyways, if it aint broke dont fix it -- so all my remaining Nanos are still with 16.7.2

Folks, with stock ROM the Nanos hash at 100 H/s with Claymore 4.0. I have undervolted core by -72mV in Trixx and they still draw 200W each (on a rig of 4, total draw from wall incl. 1820 CPU = 800W)
With -li 2 they do 75 H/s at 160W (640W total a rig of 4 incl 1820 CPU), which I prefer for my rigs, though it means quite a bit less in profit.

What is your maximum speed at the latest Claymore V5? Have you tried the tight timing bios supplied?

I tried one of the mod with tight memory timing. It seems it makes no diffierence in the Nano mining for ZCash.

heliox do you have moded bios nano for 950mhz core with lowest stable core voltage + mvddc, for zcash mining
i tried in front page but using lot of power, inst efficient, rx series has better efficiency
thanks ..... Wink

whats -li 2

li   low intensity mode. Reduces mining intensity, useful if your cards are overheated. Note that mining speed is reduced too.
   More value means less heat and mining speed, for example, "-li 10" is less heat and mining speed than "-li 1". You can also specify values for every card, for example "-li 3,10,50".
   Default value is "0" - no low intensity mode.

I'm now getting 113 sols/s with a Nano, Ubuntu 16.04, amdgpu-pro 16.40, and Silentarmy v5. Who needs Claymore's 2.5%?

I get 100sol/s @ 90 watt with a modded Nano bios. (an older eliopv etherum powersaver bios) (claymore 4.0)
Stable 12 hours now..

older rom was 800/250 (or 800/300). what freq do you use for 100sol?

My Nanos are with Heliox -100mV mods and under Claymore's v4 ZEC miner.

The Nanos are running strong some cards touching 82 h/s but most runnng at 70ish h/s

Some say they can run faster at stock ROMS but with the current power savings, I am real happy at current speed.

just changed to "-i 0" and overnight I see several GPUs (Nanos and 390s) touching 100-105 H/s !

I can reach 100 with last rom (no core undervolt) but crash every 15min (returned incorrect data).. I tried 1000/550...900/550...800/550. It's the same
