Won't be long till you reach 300‎€ at 0.06 ‎€/kWh. A few miners (5-10 depending on what you chose) will do it and you won't be able to reach the 1000‎€/month you want.
It doesn't use much data and you'll be fine mining on 4G.

I'll ignore the last point and strongly advise against mining with infrastructure that isn't yours.
You will be noticed (noise and unusual electricity usage).


If you run a zec gpu miner with 3 gtx 1080 ti cards. You will use about 600 watts per hour with not that much heat or noise. Should be more than adequate and will get you halfway toward your goal.
42  Alternate cryptocurrencies / Mining (Altcoins) / Slim PCI-E riser on: May 23, 2017, 12:23:12 AM
All,

I wanted an opinion on the slim pci-e riser. They are for sale on eBay and I have some as part of a open air mining case. Should I swap them out with a version 6 pci-e riser. From the pcb layout it looks like a gen 1 riser that is a fire hazard. I contacted the seller and they claim no problems and have sold thousands of these without any issue. The seller also say that it's a redesign and that they are a gen 2 version of the slim pci-e risers. It does not use a molex connector for power but a 4 pin small type connector on the backside of the PCB.

What do people think? I don't want my rig to go up in flames.

Are the latest batch of S9''s still autotune? I want to be able to adjust the fan speed and hash rate.

Hello mining community,

I would like to ask for some help. Recently bought a mining rig 6x RX 480

https://www.mindfactory.de/product_info.php/8GB-PowerColor-Radeon-RX-480-Red-Dragon-Aktiv-PCIe-3-0-x16--Retail-_1124443.html

I am using Biostar TB85 motherboard, 12 GB RAM, EVGA 1300w, 120ssd, intel celeron 2x2.8GHz, windows 10 64.


I have this problem. On minute after I start claymore miner hashrate on one card drop to 0 and I get report - GPU hangs in opencl call - Need to restart miner.

I am searching for solution for couple of days already.

- I tried different GPU drivers, if I try to install 17.3 or 17.4 crimson computer crash.

- Virtual memory is on 16GB.

- If I start a miner without this card which lost hashrate then same thing happen to other 5 cards, hashrate drop to 0 on all 5 cards.

- I reinstall windows and all drivers, still same issue

- I switch cables and cards, nothing positive happen.

- tried other miners, pools, old version of claymore miner..

- tried function -gser -eser

Tried probly everything i could find on google, still no solution. Not sure if that is specific problem of motherboard, graphic card? other parts are more or less standard mining parts and probly have nothing to do with that problem.

Hop someone can help or give any proposition what should I do or try.

Thank you

Best regards

Have you tried bring up the cards one at a time in windows.  Also depending on the alt coin you use crimson 15.12 for eth or for zcash crimson 16.12.2. Bring up the cards one at a time until you have all 6 going.

It takes about 3 months to get the rebate, but you will get paid at least.

Yes there is a limit of 1 per household per manufacteur per model. So with 3 manufacteurs and different models and between your home, work, friends, parents, address you can easily buy 20 of these GPUs with rebates.



did you ask your [former] wife/gf to do it when that monitor was damaged?
(I remember seeing the picture of it posted with a crack/hole, believe it or not, I have a good recall)  Grin

in short, maybe, but not very realistic. My son cringed when i asked him for such favor. "Why, dad?"

Last time I asked a friend to use his house to ship a card, it got stolen because he has shit neighbors and UPS left it as his door. So not as easy as you think to get  multiple rebates. Also if the rebate address and name does not exactly match the name and shipping address on your invoice, you won't get your rebate. Then you have to get the rebate from your friend if he hasn't spent your gift card already. Too much hassle.

I didn't even check for the limit this time since all I was buying was 1. I just know a lot of the times I see it come in stock I see someone else say they just bought 30+

These board are hard to get new. When they do get a shipment they sellout quick. Limit is good because then more people get a chance to get one. Before these came up, I was going to pull the trigger and buy one on eBay for $200 for a build I am doing. Now I got two, one just in case I want to build another rig.

Newegg makes it hard to buy more than one sometimes. This was a limit of 1 per account. I have two accounts. I tried ordering 5 for my first account and they rejected 4 and let me buy only one. So I ended up with 2 and that is all I got.
51  Alternate cryptocurrencies / Mining (Altcoins) / Re: ASRock H81 PRO BTC R2.0 LGA 1150 on: April 26, 2017, 04:42:54 PM
Wow fast. Out of stock now. Hopefully people picked up a few.

Newegg.com has them in stock right now. I just got a few. Better get them while they are available.

Well that is too bad about Segwit.  I guess we will get a lot more drama then.  Never boring around crypto I guess.  The banker class will own cryptos if we allow the transactions to be sucked off the network.  I guess we will see soon enough as the games begin.  It is brilliant really pushing Segwit out there to the public and letting us think it was our idea, and then when that wasn't enough they had to create an "enemy" who must be fought by signaling Segwit.  I swear we are just sheep...  Roll Eyes

The price increase for the L3+ makes no sense.  With Segwit there will be less profit to the miners period.  Couple that with increase in hash rate and diff...  I am curious how sites like What To Mine will calculate profitability with transactions getting sucked off the network.

On the L3 hardware nightmare issues.  I have parts coming back from China this week.  And just as I get back home another L3 has now decided to die.  This one appears to be the controller from what I can see so far.  The miner fault light is coming on and has to be reset to get the miner back online.  It has now been reset a couple of times and looks like it is not coming back this time.  I don't see it dropping boards or anything so just as I am about to get parts back to get a miner online another one is down.  This has now reached the point of being ridiculous.  

 



Bitmain seems to be having quality control issues with their hardware. I sent back two R4's that died. They didn't have any more R4's to send back as a replacement so I got as a replacement a T9. One loud MOFO. No more Bitmain gear for me unitl they fix their quality control problems.  I have a bunch of alt coin rigs going with Sapphire cards. No return of any of the cards and they have been going 24/7 for over a year.
55  Alternate cryptocurrencies / Mining (Altcoins) / Re: AX1200i dies immediately after starting up - KNC Titan on: April 23, 2017, 04:55:24 AM
Hello,

I just bought an AX1200i and an AX760i to power a KNC Titan. After connecting everything up, I hit the power and both PSUs shut off almost immediately with a clicking noise. I've seen lots of similar reports, but I can't find a solution. I've got the 24pin jumped correctly, all connections are tight, and I am using the KNC supplied Y cables.

Does anyone know how to get these supplies to run with a Titan?

I used a AX1200i once to try and power a Titan cube. Caused the same issue. The Corsair AX1200i has a power throttle on rails to protect from over current.

Well I have been off grid for a week, I come back and pop in to see what is going on.  Always the drama in crypto!  So NOW I see Bitmain has the ship dates of 15-25 July and the price has now jumped up to $1644 per unit!  Holy smokes... Talk about a gamble... they are selling further into the future and at an even higher price! 



What are they up to with the price increase? Do they have a crystal ball that sees the future and know that LTC is heading north of $20 so they increased their miner price?

T9 is located in California.

Looking to sell a T9 11.5 TH/s  that I got in exchange for a broken R4 from Bitmain. Not really happy with the situation. Wanted a quiet miner like the R4 but they couldn't replace the one I purchased so they sent me a replacement T9. Send me offers thanks.

Well my faulty R4 is now fixed and on the way back to my place. Fedex has it in Cologne (Germany) at the moment.
No details about what was repaired though.

At least they fixed your R4. They sent back a broken R4 that would not hash. I resent it back for repair and now they said they can't replace it because they don't have any more R4 units. They want me to pay some BTC to get as a replacement a T9. It's faster but also louder. Terrible customer service.

Try to get a swap without additional payment. The R4 are doomed.

Ya they won't budge. My only options are to have them send back a busted R4 or pay up and get a T9. I asked them to provide the cost and also to send me a unit that has been fully tested 100% good. I don't want to pay and then have them send a busted up T9.
