mining etherium with sli 980tis

[jjohnthedon1]

hey guys so just watched jokers video 

and it looks pretty easy to set up i wont have it running all of the time but i was thinking of leaving it running over night and when im not at home to make some extra money, do you think it will just lead to a quick death for both of my cards or a complete waste of time ?

 

looks like easy money that i can just put back into computer stuff, ei 8 hours a night and if my cards last for another 2 years that should be enoough money earnt though this for a free gpu right ?

First question: Do you (or your parents, if you live with them) pay for electricity?

 

Second question, assuming question one was yes: How much does it cost?

 

GPU mining isn't free money. You have to take cost of electricity into account. With that in mind, if you already own the GPU's, and your electricity costs aren't too crazy, mining can be somewhat profitable.

Though you better have cheap power to run a 2x 980 Ti all night. They draw a lot of power, AFAIK.

Depends on how high he OC's them, but yes, 2x 980 Ti's mining will probably be drawing 600+ Watts.

Noobs can use Nicehash for auto algorithm switching. People using Nvidia cards shouldn't mine Ethereum it suits AMD cards far better. If you don't want an easy option like Nicehash then mine Zcash (ZEC) directly as it likes CUDA. Bear in mind the average per kWh charge in the UK is near double the US -.- For me its $0.18/kWh

 

Also Pascal/Polaris cards are popular because they are much more energy efficient than previous architectures.

 

EDIT: So far that is Linus, Austin, Bryan (Tech Yes City), HWB and Joker jumping on the crypto currency bandwagon. All in the last week. Strap in folks because the GPU shortage is only gonna get worse now the exposure has exploded.

I'd also have to advise against using the 980 Ti. It's powerful, but it uses quite a lot of power to do so.

 

I don't think you'd see any damage at all as long as temps are in check. I rendered for days on end using Vray on my 980 Ti, it's still alive, overclocked as well to 1.5 GHz.

 

I'd say try to get the pascal cards (If you can even find any at a decent price). I'm actually trying to sell off my two 1070s to some one on ebay so I can change them out for 1080s for faster rendering times.

Not really worth it, 980 Tis draw a crap ton of power so you won't make a lot of money.

Two 980Ti cards right now can bring you about $5 to $6 per day mining zcash with NiceHash if you mine 24/7. I monitored power draw and each card pulls about 250 watts under full load while mining so you're looking at 500 watts/hour. Determine the cost of electricity per kilowatt/hour and then you'll see how much profit you'll make (if any)

For those who are saying not to do it on a 980Ti due to power, have you actually looked at the math or just making it up as you go along?

 

980Ti is rated at 250W TDP. You can use that to work out your estimated energy costs. I'm charged equivalent to US$0.13 per kWh, so running 250W for a day costs $0.78. If the return from the 980Ti is greater than that, you're in profit. Based on software monitoring, my cards run below 100% TDP while mining.

 

If you go through nicehash, they're currently indicating an estimated payout just under $3 a day for a 980Ti. Subtract electricity costs and you've got just over $2 a day profit. Nicehash will switch mining to whatever is more profitable at the time so you're not limited to etherium. For nvidia cards, you'll more likely find it doing zcash. Regardless of what you mine, they pay out in bitcoin.

 

Now there are further refinements to this. The actual power consumption may not be the rated TDP. If the cards are over-volted, removing that will often lead to a good reduction in power. The system power would also need to be factored in. Also factor in the performance of a given card may differ from the example from nicehash calculator. You can download the client and it will do a benchmark and give you values for your card.

 

As a further caution, the power above only applies to the power directly taken by the card or system. If you're using air conditioning where the system is running, that will have to remove more heat and the electricity cost will go up more.
