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! Greetings

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!

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

The bottleneck is in the GPU core. That is similar to the R9 390 series.

But the issue isn't the bottleneck regarding the GPU core, it's purely the fact that all these "mining algorithms and their miners" aren't designed "yet" to handle this amount of bandwidth. In short, HBM is in a way not yet fully supported..."

The memory is only used about 96% when the core speed is 1080MHz.

i thought the algo was most efficient running in increments of 250mhz..
that seems to hash out with my testing too.. for another 50mhz mem clock you should see nice gains.

It's unlikely anything to do with the algo or some ratio, and almost certainly to do with mem straps. Don't think I've ever seen the memory timing ranges posted for fiji cards. They may align on 250mhz.

What do you mean by that? Can we disable the GPU parts which are not used in the computing so as to save energy?

Well i'm @ -150mV at this moment and still running stable. Will let you know when i hit bottom..
Srsly? i had no idea this could run that stable tbh and thx for the little movie ~CfA~ what tool did you use to mod your nano ?

What do you mean by that? Can we disable the GPU parts which are not used in the computing so as to save energy? I remember back when people mined scrypt some dude made a great deal of a modded BIOS. One of the things I remember is that yes, he said you can shut down whole GPU blocks. The power consumption was greatly reduced - oddly, as the whole point of using compute is to bypass ROP units. But I don't know if you disable them 'forever' to next reboot or what. I certainly wouldn't do that for cards which are not dedicated to compute only as shutting down the ROPs will make the hardware unable to run any graphics API in existence.

Hey, i use HxD and a calculator to modify the values. After that i use Fiji Bios Editor to fix the checksum Greetings I would like your bios but its hash rate is a bit too low for me I have around 8 saphire nanos I notice on afterburner you cant reduce the memory clock on any cards not even 390s You can reduice voltage a max of 100mv of course and power tune and core clock. would this tool work on the R9 Nanos and the 390s to reduce voltage and Memory clock ? https://github.com/OneB1t/HawaiiBiosReaderor can you provide a new modifed bios that hashes at around 150mh/s rather than 130ish leaving 30 mhs on the table seems kind of a waste.

If the R9 390's memory voltage can be reduced. That is excellent. We need no more than 1250 MHz.

Hey Marvell1, The rom i shared has a mod on the core voltage (-100mV) and a mod on the mem voltage (also -100mV) You can open afterburner and go even lower. So if you set (-12) you will have -112mV You are correct, you cannot reduce the memory voltage with afterburner or any other software. This has to be done with a hardmod. The Rom i shared can easily hit 150Mh because you can still set 1000 as core clock (it is stock set at 1000). Thus giving you full power but with less energy usage. I will share my second rom as well. I will edit the op. This one is even more energy efficient. Although it is set at stock 800Mh Core clock. (you can up this to 1000 in afterburner if needed). Greetings.

If the R9 390's memory voltage can be reduced. That is excellent. We need no more than 1250 MHz. I have no experience with HawaiiBiosReader. But i'm sure you could perfectly modify your bios with a hex editor. I would advice you to look up some tutorials. It's not "that" difficult. I do own some 390's as well, so when i find some extra time i'll look into it and report back. Greetings

Lower mvddc, better timings, fixed dpm values :-) Some dwarfpool-side results, with a watt-meter reading, would be gladly appreciated. Have you tried claymore's dual miner with such low voltages (eth+dcr)? I suppose that it would be too unstable with blake256. Keep up the good work ! thank you!
