Can anyone share hashrate of Sapphire R9 Fury on mixed with RX 480 rig. I get 395 sols with 1140/500 stock bios on 17.1.1 drivers.
Shall I get better performance of 16.3.2 ?

The RX 4 series works better with 16.x drivers. I cant speak for the Fury, never had any.

Fury runs best on 15.12 with asm enabled. Stock clocks and bios gets you around 415 H/s

use msi afterburn. i've been able to lower the 290x to 125 watts average as per gpu-z. In my case i'm more worried on the fan noise so this voltage lowering brought the temp to the mid 60s and the fan to 60%, this while maintaining the sols at 337 to 347

What you see on gpuz is not the total power consumption of the card. 125w for the gpu only is possible but with the rest of power components on the pcb the real consumption is much more(about 200w). Check with wattmeter if you don't believe.

Agreed, but the numbers for the GPU are still absolute so any savings you see on GPU level are still 'real' power savings.

In theory this is true but it is possible that only the asic power is dropping while the rest of the package is going up to make up for it. Use hwinfo instead of GPUz, it will show you multiple power readings. You can usually add the core power and "GPU Chip Power" together and thats your actual at the wall wattage. (your results may vary!)

Basically there is more than core voltage, asic values and TDP. These are the things commonly thrown up on these forums because they are the easiest to understand/adjust.

And if I understand it correctly, lowering core voltage forces the GPU to perform 'more work per watt' while setting power limit simply sets a hard limit on power consumption, forcing the GPU to throttle down rather than suck more power when it approaches the set limit. Right?

1) Correct. It does the same work while using less power and producing less heat. But at some point it will get unstable.
2) Correct. Less work but also less power and less heat + safe & stable.

Do you undervolt/overclock your Nano? I have Fury's and would like to drop my power draw. What's your settings?

nothing!

off the box on Windows 10 (Pro)
install 15.12 drivers
set power limit 50%

i don't play with volts or OC of the Nanos i get electricity pretty cheap like € 0,05 per kW (normal consumer pay like € 0,23 per kW)

I also have cheap power, but I would still like to run 6 x Fury on a 1300w PSU. That's why I'm wanting to undervolt them.

use msi afterburn. i've been able to lower the 290x to 125 watts average as per gpu-z. In my case i'm more worried on the fan noise so this voltage lowering brought the temp to the mid 60s and the fan to 60%, this while maintaining the sols at 337 to 347

Noob question. Does afterburner write to Bios or does it alter the wattage on software load? What do you set to lower the power? Powerlimit or actual mv offset?

Afterburner does not change the bios. Some cards you can lower the core voltage with it and you can adjust the power limit on most, if not all cards to some extent.

And if I understand it correctly, lowering core voltage forces the GPU to perform 'more work per watt' while setting power limit simply sets a hard limit on power consumption, forcing the GPU to throttle down rather than suck more power when it approaches the set limit. Right?

Care to share bios/settings?

I have 6x rx480 4gb , it is simple copy 1500 timing to 1750 and 2000, i run 1350/1950, -106 mV, 1580 sols 910W at wall

Do you use a custom bios or do you use software to set the timings, clocks and voltage offset?

I use original bios with changed memory timings (polaris bios editor), i use trixx to set clocks and undervolt, always checking for memory errors in hwinfo, but have only one rig so have time to do it manually

I have heavy overclock, undervolt, 6 cards rig. I run hwinfo, if any card produce memory errors it will be unstable, i have to sometimes start miner 4-th 5-th time to not produce errors and then it runs stable all time ..

Do you Bios mod or undervolt/overclock via software? If so, what software? I am trying to figure out how to run my Fury/480 at stock or over with as low power draw as possible.

Yes they have memory timings changed, i undervolt by trixx with offset, not by miner

Optiminer 1.6.1 seems to be some 15% faster on 280x and 270x, power draw is equal.

I see about a 15% increase on a Radeon R9 380X (175 h/s vs 200 h/s)and about a 35% increase on a Radeon HD 7870 (125 h/s vs 175h/s) using Optiminer. However, I've found Optiminer to be far less stable than Claymore. I've been having to restart it every 3-4 hours and I'm also seeing "block" pixelation pretty consistently while Optimer is running. I do not have these issues with Claymore and for that reason I've switched back. At this point in time neither application is perfect, so pick your poison. I'm hoping Claymore's next release can match (or exceed) the speed of Optiminer while remaining a stable build.

hmmmmmmm So far optiminer hasnt crashed on me once. Maybe scale back the core clocks ? running 380s, 390, 280x on 15.12. Maybe i'm just lucky.

Yep, 20+ rigs running optiv1.6.1 and rock solid, not a burp for days.

Same here.. Optiminer seems to be winning miner 5x R9 Nano at 2100/2200sol and i have 115 of them:)
