I think I paid $180 for my "refurb through Newegg" 290s.

thanks for info..

At this point I am mining with 4x r9 nanos doing around 100mh at 750 watts

-65 mv 1000 clock for gpu 500 clock for memory no mods

i'm consuming the same with my 5x970, 773w(system included) at 100MH, i think you can do 88MH at 320w(system excluded)

p.s. shouldn't nano be at 80w, with that mod?

I think his setting is not right. I use the mod BIOS with 6x nano. I can do 159 MH/s at 750 W. He should be much higher.

My 6xNano@[email protected]@133MHs using Heliox's -150mV rom mod

Did you use the -175mV or -200mV rom mod to get 159MHs?

I have similar setup with 6xNano. I run 900/260 MHz, with about 760W, 159 MH/s. I use the -200, -175 mod. I use the 93% platinum power supply.

so you use the DPM-175mv.rom file? What brand of Nano?
I am at -175 now, but I use 1060,300 getting 60MHs with 2 x Nanos.
How do you use the -200, reduce another 25 from -175?

I was lucky. So I use the -200 and -175 ROM. They are Sapphire cards.

4 cards work with -200, two cards work with -175.

There was a -200mV BIOS.

So I've finally consolidated my four 480s onto one platform, utilizing the Biostar Z170 board noted below.

However... The stability of having all four cards hash consistently at/near 24-25 MH/s is just not there. After a few hours, one of cards seems to drop down to about 8 MH/s and stays there. Is this par for the course, or are other peoples' rigs "rock solid"? I have a 750W gold-rated PSU pulling about 630W at the wall. I do have a 850W I could swap around, if that would help. I've been contemplating a script that reboots the machine every 12 hours, or so, to get things to return back to normal. Are other people rebooting often?

Could you please add your data here?

On the card dropping the hash - I had a similar problem with rig on 4 R9 R390 cards. It was one black sheep (PowerColor) which does not hold any settings except stock. At the moment I've stopped to over/under it - rig works perfectly

When you mine it, it is more profitable than the ETH, but when you sell, the price is lower.

It is not "profitable" - due to lower difficulty you getting more coins per MHs spent

And price is not volatile - it's going down as crazy

be careful ETC is much lower in price then ETH make sure you know what you are doing.

I sold mine yesterday at 0.004BTC - today it is 0.0023BTC

But who knows - maybe tomorrow it will 0.4BTC (I will be crying)

The ETC price is too volatile. When you mine it, it is more profitable than the ETH, but when you sell, the price is lower.
