Topic: Ethereum mining still profitable? - page 34. (Read 131243 times)

A hot summer could possibly provide some salvation if those farms have to throttle down on their mining activities, I think some of the numbers could be some variance in the hash rate.  I would be happy if we could chill at the current numbers for a bit, the increase has been slowing down a lot.  Eventually the farms have to stop growing and wait to catch up on ROI, hopefully we are in that phase now or wont see crazy increases like the past 2 months.

...and then the difficulty drops hurray!

I just watch the Youtube video of Genesis Mining farm.They added a lot of GPU in the past. That could be the reason of the big rise.

If the difficulty doubles again from here, most people in Europe and California will not be profitable in mining.

The difficulty has resumed its upward trend. It is a new all time high of 34.9T. When the new efficient GPU cards come out, it will be even higher.

Ethereum mining is still profitable for most of us. It seems there is a pause of the difficulty rise at the moment.

I think there is no P0 state in the AMD cards. I might be wrong. Where do you change the P0 state parameter?

try to runt hem in p0 state, and overclock the core a bit, the mem isn't needed for etheruem

Stilt modified the GPU memory timing, it is faster than the stock setting.

tell me how do I do that ?? Stilt memory , never heard of it

That is quite slow. It should be around 17-18 MH/s. You might have a slow video memory. You need to use Stilt memory mod.

Mining with single 7950 @ stock clock and getting 15-16 mhashes, is it ok ? What should I do to make it more profitable ?

I have 5X390, I use -200 mV and 950/1000 MHz. It does 137 MH/s. The power consumption is 910W. No bios mods.

Does you 290x hash the same speed as 290?

Gonna be interesting to see how well the GTX 1070 and 1080 mine Ethereum.

 I just wish they were releasing them at the same time - the extra 2 week or so wait for the 1070 is gonna su..... er, be irritating.



 Also going to be interesting how soon and how far pricing on the higher end GTX 9xx series tanks, especially the 970/980/980ti and the Titan....

Surprisingly warm weekend here so did some power saving tests with my 5xGPU rigs AMD against Nvidia.

AMD 295x2 x2 plus 290 (=4x290x + 290) undervolted -100mV does 140MH (Claymore), 1120W from the wall. No bios mods.

Nvidia 4x970 + 980 TDP limit at 61% 90MH (Genoil 1.0.7), 680W from the wall.

W/MH:

AMD 8.00
Nvidia 7.55

For the Etherem mining, the R9 390 is the same speed as the 390x. Is the R9 Fury the same speed as the Fury XT?

Yeah but if you're also a gamer running two water cooled nanos is awesome!

Nano is more power efficient than the R9 390. But its ROI dates are much longer than the 390. So it depends on your power price.

Nanos aren't all that efficient at mining Ethereum - probably for similar reasons anything much past the R9 280/380 aren't either.

 They're OK on a hash/W basis but pretty bad on a hash/$ basis - R9 280 / R9 280x / R9 380 are all a TON better on hash/$ while being competative on hash/W.

 My triple GTX950 soaks a little under 350 watts to do a bit over 30 MH/s - but that's with an A10-7860k running Prime95 on all 4 CPUs *AND* dnetc RC-5 on the GPU (it doesn't have enough memory to mine with) so if I went to a more efficient build I could get that under 300 watts without trying hard.



 AMD cards are definitely the way to go for Ethereum on a Hash/$ basis, but Nvidia Maxwell cards (other than the 750Ti, not enough memory) are pretty competative on Hash/W basis despite being way down on hashrate vs "comparable" AMD cards.



 Only reason I went Nvidia on the 2 machines I have mining Ethereum is that the ORIGINAL plan for those machines was FAH - where Nvidia DOES blow AMD out of the water (a GTX970 is capable of better PPD per every comparison I've seen to ANYTHING AMD has out currently except the dual Fury card and MAYBE the Nano/Fury - for LESS power usage).
 
AMD on the other hand blows Nvidia off the bloody PLANET on RC5 work, my ancient HD7870 outhashes my GTX970s by about 15% when both are not OC despite being a 5+ year OLDER design and having the same number of Stream units as the 970s have CUDA units - keep in mind that AMD cards have 1.5-2X the Stream units vs the "comparable" NVidia card.

mine is 132 MH with only 1kw, six 970 rig, very stable, +150 on both core and mem, iot give you almost 1.5 ethereum per day
