Title: GPU Etherium mining concerns
Post by: molitar on February 21, 2016, 05:09:41 PM
Windows 7 x64
Sapphire Vapor-X R9 280x

Running on nanopool and I notice that my hash rate keeps dropping from the almost 21Mh/s for Ethminer to 8.8MH/s a second. Not only that after a good 12+ hours running I did not receive any payout.   I have now moved to Suprnova and mining average 22.37MH/s and already got a small payout of .12 us dollars..  I don't trust nanopool.org at all..

Also is there a better software than ethminer that you can tweak GPU settings can it be tweaked in ethminer?  I would like to know how to tweak in ethminer for my GPU if it's possible.

same thing with me on nanopoop hashrate not stable and gets stuck on 8.8 lots of time , i dont even get stable hashrate on supernova .

Ethereum shouldn't be pool mined. Solo mine instead. Even if you only have 1 GPU. You'll hit a block in about the same time it'll take you to earn 5 eth on a pool, probably even quicker actually.

with 17.8 hashrate how long it will take u think ?

8.6 days to find a block on average.

When the difficulty is rising fast, it is better to do pool mining now. As you can get payment when the difficulty is still low.

You cant be serious, mining on a pool is far better than solo mining unless you have over 2ghz of hash
You waiting days for a block is not smart unless you have free power.

You have to wait days for a block. When the block is found, the difficulty for the next block has already risen, the chance you will get next block is reduced.

I tried to get solo up and running but found pool setup to work without issues.  Nano pool does fluctuate with extreme spikes, thought it was my settings.  I find Ethereum to be a challenge due to scattered bits of info and guides that are too general.  Much like any new crypto I suppose.

yeaa me too on nanoopool i get really bad hashrate on the site with spikes up and down to 0

i've got 19.454929 ETH from http://dwarfpool.com/

What is your 390x hash rate? What is the core/memory frequency. what is the reading of power in and power out in GPUZ?

about 28MH

So that is no better than the same clock R9 390. I wonder why. The power consumption is also higher than that of 390.

strange should get little more owell get more then with my old GPU 66ti = 8MH

sanadas

what settings are you useing?
mine are
ethminer --opencl-platform 1 --opencl-device 0 -G -F http://URL/gpu1
windows with Non-WHQL-64Bit-Radeon-Software-Crimson-16.2-Win10-Win8.1-Win7-Feb23

tried latest 16.3 but then i got slower speed like 20MH so i went bak to 16.2

True. And it's possible to do even better deals. Although, you'd have to buy in bulk...

Is the Fury nano faster than the R9 390? I heard the HBM is not suitable for the Etehreum mining due to high latency.

Is the Fury nano faster than the R9 390? I heard the HBM is not suitable for the Etehreum mining due to high latency.

First, it's just R9 Nano, not Fury Nano, Fury is a different series.

You've got

R9 390
R9 Nano
R9 Fury
R9 Fury X

I own all of those cards, the Fury X gives the best hash rate.

Regarding power use / hash the Nano tops it with ease.

Further, the memory doesn't matter at all as the ethereum algorithm doesn't use the memory of your gpu.

I even down-clocked the memory of my nano's to 300 and i kept the exact same hash rate. (obviously..)

So in other words. HBM based cards are perfectly fine for Ethereum mining.

How fast is your R9 nano and the power consumption? If it is better than 5J/MH, I will think of buying some.

Well, at this moment i'm doing around 2.6Ghz on Ethereum while using 9.5KW (from the wall) (95 GPU's)
Downclocked to 850 core and 300 memclock. -100v.

You can do the math yourself :)

So it is 100W each Nao. What is the hash rate per nano? Is that better than the R9 390 which is 29 MH/s stock?

the nano does 26 so it's lower than the 390 but the consumption is far better, the price not so much..ah and gamers does not really love expensive gpu so it will be hard to sell

The nano does 26 MH per 100W, or 3.8J/MH.  The 390 does 31 per 220W, or 7J/MH. Which one ROI faster?

The Ebay price is quite high. The 7990 costs about $450. But it is a good card, it has 4096 cores in total.

there are plenty of other, you searched in the wrong place lol

That's a reseller,they do not offer free games/gift cards/rebates & promo codes to "sweeten" the deal.
Plus "Returns:No returns accepted" means if you get a defective card,you could be in for a rough time getting satisfaction.

A new Sapphire 380 4gig on Newegg was actually $194.99 (I goofed up the above price),got a $20 gift card with purchase so + shipping=$179  ;D

Has a $15 rebate too,but they rarely work,so no rebate for me  :(

Plus Newegg offers promo codes on their homesite (DFHSDE892) as of now  ;D

op needs to learn how pools work.  Basically you submit shares that tells the pool you have done some amount of work for a specific block.  Your hash dips like that becuz you don't find shares over a certain time frame, then you get lucky and find a bunch so it levels out over time.

Forget buying vid cards on Ebay,WAY overpriced  :P

I got a new Sapphire 380 4gig for $199 with 3 day shipping from Newegg & $20 gift card  ;D

It does 22mhs @ stock clocks & fan @ 80%= 57c  8)

Check thru all the pages,deals can be buried deep  ;)

The Ebay price is quite high. The 7990 costs about $450. But it is a good card, it has 4096 cores in total.

The 7990 can mine about 40MH/s. That is more than the Fury X or Nano. But the power consumption is more.

i'm wasting 166w per card , 970 for mining ethereum with 22mega

someone has a better performance?

Sure Nano's..

well it cost 60% more, so it's not that better, you pay upfront the electricity for 1 year

I have seen some retailers selling XFX Nano for 399€



That is very cheap, in UK, the cheapest price is £379 including vat.

The R9 nano price has risen quite a lot now. That could be due to the GPU mining of the crypto coins.

could this be that my R9 290 became effective mining . Previously, she gave out 27 mh. and now 28.5

Did you do anything to increase the speed? I am very surprised that the hash rate will increase by itself.
