please add me.

I have a couple S9s, L3+s, D3s, and a 5 GPU 1080ti rig.

Would like to discuss mining strategies with folks.

So I've been waiting for Finksy to start selling his power supplies again.

 I have one of each of these power supplies from ebay.  I have only had a chance so far to run the 2,880 one and it works quite well.  In the ebay description they mention that they aren't a fan of power supplies with breakout boards and that connections should be soldered.

For those that have the parallel miner PSUs, how do you think they are compared to these two ebay power supplies?

Take a look at this guy's setup.

Saw your youtube video.  Quite impressive.

Know where I could find a 19 GPU frame to be shipped to the U.S.?

I've looked at ebay.com, but so far, the max they have is a frame for 14 GPUs.

Yah - I saw that as well.  16 PCIE on the motherboard and then add another 16 for 8x GPU cards (at least for the 1080ti cards) for a total of 32 PCIE.  That's quite a lot.

very cool.

I would be interested in seeing if 19x 1080tis will work in Linux using something like nvOC or SimpleMining distro.

please keep me posted on when/if you have a chance to do something like this and when the MB are for sale.  Would at least like to try one out and see how frustrating it is to try to get 19x cards to work/stable.

Hey all.

(I posted this thread here in the altcoin section because BCH is considered an 'alt' by many.)

So right now I have 2 S9s.  One S9 I have mining BTC and the other S9 is running BCH.  I'd like to setup auto-switching between BTC and BCH with payout in BTC.

looks like maybe zpool, f2pool, and nicehash have this capability?  Any others?

Thanks.

That would be cool.

Especially if some/all of the crypto was in an escrow and if equipment wasn't shipped out by xyz date then reduction in price, refund of money, etc.

Finksy,

Are you back up and running yet?  Would like to get a couple IBM 2880W power supplies, cables, and picos from you.

Hah.  I don't expect a reply, (actually they gave me a KNC form to fill out) and the worst they could say is no.  If you don't ask, you don't know.

Yah.

My thought was that if  you had a 1 year lease, you could get a loan (or group of miners together) to pay for the first month, and then use the profits from the first month of mining to hopefully pay back the loan (or at least a substantial part) and future months of leasing/hosting.

Not sure how much the monthly lease would be, but it would be more reasonable to come up with (although would still be a chunk of change) than 1.2 million.

Are they going to release their custom OS so this could be ran on any hardware, or does one have to buy their box?

Yah.  I asked if they would lease one for 1 year (mining equipment gets outdated so fast) and what the cost would be but no response back.   

I asked bitfury and this was their response.

BlockBox IC -
The BlockBox IC (15PH unit) is sold out.  The last batch BlockBox IC sold for appx $2.5m USD per 15PH container consuming 2MW.

BlockBox AC -
BlockBox AC is available as a 7.5PH unit consuming 1.1MW at a price of $1.2M

Windows.    Will give your suggestions a try and report back.

Thanks.

Hi.  I have the following motherboard, PSU, and GPUs.  I bought 5 GPUs and right now I only have 3 out of the 5 working.  I would like to get the other 2 working.  I’m using risers.  I’ve verified that the cards and risers are good – put them in a different machine.

I think there is probably something in the BIOS I need to turn on, or maybe I need to jumper a PCI slot in the motherboard?  I’ve done some googling and it appears that some of the motherboards need a PCI slot jumpered with a wire in order to get the rest of the slots working, is this correct?

Appreciate any thoughts you may have.

So I currently have 5 of these 1080ti cards - MSI GeForce GTX 1080 Ti DirectX 12 GeForce GTX 1080 TI ARMOR 11G OC 11GB 352-Bit
http://www.ebay.com/itm/382016280684?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

Currently have 4 (hope to add a 5th using the M.2 port) of them in the mining rig using nemos-zpool and trying to get the cards stable.  Haven't done any setting tweaks yet.  Will startup nemos and sometimes the rig will start mining for a few minutes other times only a handful of seconds and then the box will reboot.  Currently using nemos-1.7.4 and will try the latest 1.7.6 to see if this fixes any issues.


Anyone using this card and/or has some tweaks for it?  Trying to get nemos-zpool to work, but open to others software/pools if I can't get my cards stable. 

Goal is to mine most profitable coins and then switch/store to BTC/ETH/Dash.

Thanks.

Will be getting 5x 1080ti here hopefully by the end of the week.  Currently, looking to try to get nemos auto-switching on zpool up and running and compare it to nicehash and will report back results so we can compare.  Any other mining software/pools I should be looking at?

Alright.  Just broke down and ordered five 1080 ti cards to mine zcash.  Now trying to figure out Linux/Windows.  If Linux, which distro? Does Claymore's program support the 1080 ti cards in Linux?

How many kW are you running and what are you paying per kWh?  Have you seen your electric bill yet?
