Topic: choosing dedicated miner vs gpu (Read 713 times)

Zeus miners were quite a bit LESS efficient than the A2 or Alcheminer, much less the Titan.
*IF* you have cheap enough electric they MIGHT be profitable enough to repay an investment into them.

hello, listen if I put in his two 280h, worth Needless to drip or ether, or still consider other coins, I have now is 280h and 270h, I realize it is not enough in the day to 0.07 ether somewhere. that advise?

Hi thanks for the info i'll have a good read, unfortunately I don't have 2xhd7970's I was asking if these cards and the other hardware I posted would be suitable.

dude you have two working hd7970's correct?

you should be mining eth coin with them

ltc needs dedicated asics

eth coin you can make cash  profit right now with your hd7970's

right now

you have around 34-39mh  with your two hd7970's
you can mine here.

get your self an account here

https://bittrex.com/

deposit that ltc you have and change it into ETH coin you will get an address use it to mine to.

this is so easy for you to do.  And Eth will turn profit instantly since you have gear that can mine it at a profit.
even with 25us cent power cost.

maybe even with 35 us cent power cost.

Thank you for the detailed reply it seems you may well have just saved me a lot of money and disappointment. I like the sound of the Innosilicon A4 but I suspect it's going to be way way out of my budget.  Funnily enough i'm currently mining on a Gridseed GC3355 and while a neat little unit i've made around 10c in LTC in about a week hence the need for more hashing power.

I will keep an eye on the for sale ads and try and pickup an A2 or Alcheminer. I did look at the titan but again way over budget. What is the Zeus 20M box/range like?

Don't bother trying to use a GPU to mine Litecoin (or any other Scrypt-based coin) with.
You will LOSE money bigtime.

 In the 100MH/s range, you'd be looking at an Innosilicon A2 "Mega Terminator" unit - max turbo mode on those is about 110MH/s, non-turbo mode around 90ish at slightly higher efficiency.

 That ONE UNIT will consume ballpark 1200 watts in max turbo mode (depending on efficiency of the power supply) - getting to that hashrate with GPUs would need ballpark a HUNDRED GPUs (perhaps 50 if you go with the dual-GPU on one card type) and would eat quite a few kilowatts.


 The other commonly used options currently are KNC Titans (somewhat more efficient, but more prone to die and tend to cost more) or Alcheminers (and their clones, about the same efficiency as the A2 units but need an external PS and only come in 250MH/s units).

 Innosilicon has a new unit showing up in around a month, the A4 Dominator - you might want to look into one of those units.


 As of this time, Innosilicon is the only remaining company making new Scrypt-based miners - everyone else has either gone bust (KNC, Alcheminer, Silverfish), gotten out of the business but might still exist doing something else (Zeus, Grideed/SFARDS), or was a scam.
 The Alcheminer folks announced they were planning to work on a second-generation unit, but apparently never got the pre-order/crowdfunding together to actually do so.

 For reference, even the original Scrypt-capable ASIC (the Gridseed GC3355) was capable of quite a bit higher efficiency than ANY GPU ever managed - my bladed routinely did about 2.7 MH/side at about 40 watts/side.
 They probably are more efficient than even the new AMD RX480 would be capable of, much less older 28nm GPUs like the R9/HD7xxx AMD series was - but by CURRENT standards the Gridseed-based miners are money-LOSERS mining Litecoin unless you have VERY VERY CHEAP electric (they CAN eek out a small profit at 3c/KWH) or FREE electric.

would one of these models be suitable?

In terms of gpu , u would want to get one that is efficient ,R 9 3XXX series can be considering your budget. You can check e bay for good 2nd hand or gpushack.

I've recently dipped my toe into litecoin mining and looking to expand. I've looked at lots of different dedicated miner hardware but when I search the forums I find the company has either gone bust or was a scam. I'm looking for around 100mh/s. I've also looked at gpu based mining but thought I read somewhere that this will be obsolete soon is that right? I have a budget of around £500/$650 (slightly more for right setup).

PC based I was thinking of something like
ASRock H81 Pro BTC motherboard
Celeron G1840 CPU
HyperX Fury 8GB DDR3 1866MHz Memory
SAPPHIRE 2x HD7970 (BOOST EDITION HD 7970 3GB 5800MHz GDDR5 950/1000MHz GPU 384BIT OC) gpu's
PSU

Would this be a good setup? or would I be better going with a dedicated miner?

UPDATE: i've just read the 7970 will do around 750 kh/s is that right? if so I may as well buy 2nd hand gridseed blades?
