Claymores Dual Miner.

Thanks I will check it out.

CDM mines ETH and DCR together.

I use the ETH only mode, and CDM can push the 390 to near 30MHs.

I used qtminer before this because of the Stratum mode, now it's all CDM for my 390 rigs (149.5MHs@5x390@1290w-1350w@-100mV/1028Mhz/1500Mhz). Quite slick this miner, and its has many bells and whistles like failover, monitoring, solo-mode w/o proxy and it's Stratum compliant too.

I will be attempting Eliovp's Nano mod for my first Nano rig (I am still trying to get an afternoon off to do this). And combined with CDM, I think we have a winner for the highest hash at lowest possible wattage, amps for ETH mining.

Have you tried to mine with 1200 memory frequency. For my XFX 390 cards, there is no difference between 1200 and 1500MHz with 1050 Core.

WI'll try it out. My 390 is MSI so I think no issues in underclocking the memory mhz.

Thanks - works like a champ!

Try 1125, 1200 is a weird number in case of your timings.

1500 or 1375 or 1250 or 1125 is more like it

Eliovp.... done -100Mv/1050/1125.... 5x390=151MHs.
Do you happen to have a ROM mod for R9-390?

Btw, I have my Nanos in, I haven't spent time on the applying your mod yet. My first attempt gave me an error "GPU not found", when I ran the atiflash command with the parameters in your guide. I stopped there and will spend a longer weekend to do more reading. Any ideas? https://bitcointalk.org/index.php?topic=1424132.msg14946664#msg14946664

Will comment on that later mate, or perhaps help you out, but gotta go now, already late again for a meeting.

I have a rom for a 390(reference "hard to find") and will share another one that's running on my nitro's as soon as possible!

Greetings!

Hi there - can you share the r9 390 sapphire nitro rom with us - that will be useful
Thanks in advance!
