So when they forked Litecoin, did they also change the algorithm from SHA256 to Scrypt?
Litecoin Cash is SHA256. I'm investigating. Yes and they will try to make a weak hashing item like sidehacks sticks and pods mine to a lower Difficulty. It is an attempt to bring older gear back to life. It could add value to the pods and the 2 pacs. Buysolar got a spondollies sp20 running at a pool. He said it was earning better then the s9 he pointed at it. Lcc.multipools.club |

A suggestion. Do 45 not 51
Run 15 on each leg.
I say this due to a guess that you mine in a hot spot not cold.
Heat will reduce the psu efficiency so 15 per leg or 45 may be the safe way to go.
45 is still a lot more then 32.
You can keep 3 -6 extra and add them later if 45 work great .

I have this rig https://www.youtube.com/watch?v=1hZ0U1x_uZoan absolute monster. if you really have 50k and few power I have good things for you to buy. Some from real companies with real warranties. I could show you how to order from hp.com some very good rigs. Thanks for the video that was informative. I would definitely be interested in hearing your recommendations from hp.
I would start by paying about 1k and finding a consultant. 49k + a consultant will give you a much higher ROI than 50k and a bunch of people in a forum talking crap.
Any experiences or testimonials for consultants in pursuit of this path? I have never worked with consultants before. Where are you located?
The mining would be located in US East - if that is a sufficiently specific answer to your question  Regarding motherboard and CPU, the Octominer B8PLUS motherboard with integrated CPU is probably the best value and is very reliable. http://octominer.com/This seems like it could be promising, and I will investigate this product before giving it a test run. Thanks for the conversation everyone! You never sent me a pm the hp rigs are gone sold out |

If you use so noisy fans (above 53dBA) why did you select 25mm thickness fans? Delta fan models like ffb1212VHE or even ffb1212SHE with 38mm thicknes has 1.5 times better airflow and air pressure than you use. Also about 70C degree GPU temperatures at datacenter conditions is not good especially for 1060 GPUs. What will be with 1080 or 1080ti GPUs that have 2 times higher power consumtion and correspondingly heat production? The review is not mine and the reviewer states temps are under 70 c not at 70 c He used Delta FFB1212SH 120x25mm Super High Speed Fan and each one uses 5-6 watts less then the ffb1212she Delta FFB1212SH 120x25mm Super High Speed Fan http://www.sidewindercomputers.com/deff12suhisp.htmlffb1212she https://www.digikey.com/product-detail/en/delta-electronics/FFB1212SHE-F00/603-1081-ND/1014412since the gear has a lot of fans you save some power over the one you mentioned. now the ffb1212vhe uses same power and moves 170 cfm that may be an improvement of course the gear will be 1 inch deeper using that one. He may do that when the more power gpus are available to him. I will find the 70c reference in the stock review. "From another angle, you can see the twelve Delta brushless fans that keep the 16x NVIDIA P106-100 GPUs cool. These are the class of fans we commonly see in servers instead of consumer focused fans, and they move a lot of air. Our GPUs were kept sub 70C without issue." "The system performed extremely well during a few weeks of testing. We did not see any issues during our testing in a 72F / 22.2C data center." See the two references. Temps may be an issue in an 85f room. But don't fear when I run real world tests they will be more rugged. My garage will be 85-90f. The solar array will be 90-95f we will see how cool gear stays. I also plan to add panels to direct air flow left and right sides and top and bottom. fan images below   |

Sent the email below a few minutes ago: Re: Dragonmint Sunday, February 25, 2018 12:35 PM From: "PHILIP Axxxxxx" <philipaxxxxxx@yahxxom> To: philipaxxxxx@yahxxom "Yoshi Gxxx" <yoshi@bixxxxxxxxxxxxyom> Dear Yoshi Happy New Years! Now that holidays are over I thought I might ask if you can get 1 early unit as you mentioned to me in our emails. I would not reveal anything to the public other then that it works along with the power it consumes to hash at 16th. I will soon be doing a nice gpu review a large industrial style 16 gpu unit. https://bitcointalk.org/index.php?topic=3015786.0It would be nice to get a unit from you as soon as you can provide one. I can pay with paypal when you are ready to ship the early one to me. I would need 5 all told.. 1 soon then 4 in late March . Buysolar and I are planning to add a second solar array which will more then double our power So units from you and the 16 gpu units will be nice to have on hand. Best regards, phil Note I am posting this email in the dragonmint thread |

It uses one of the best server psu's on the market. The delta 2400watt that parallel miner was selling. For that alone I like it. It has 1 small low end gpu I think a nvidia 730(not sure) so you can have a screen to view. Plus the 16 mining gpus. Does around 4800 to 5100 sols of zec. This is the cpu. https://ark.intel.com/products/91558/Intel-Pentium-Processor-D1508-3M-Cache-2_20-GHzIt can use ECC ram. It has a TDP of 25 watts. It has ethos on a usb stick to run the gear. The display GPU is provided directly by the onboard ASPEED Baseboard Management Controller (BMC) from the Supermicro X10SDV-2C-TLN2F motherboard. We have recently completed development of the 'Power Backplane' which will allow up to 5 x 1200/1500W Common Slot PSU's to be combined into a single power feed. This is to support up to 16 x P102-100's, or higher wattage GPU's (300W TDP each) once they become available.  Thank you for your clarification on graphics gpu. The Power back plane is a good option. Will you use it to create redundancy for the psus? Or just to allow for upwards of 5000 watts per unit? My solar array with buysolar is not small and I hope to have it expanded from a 1 ⅓ acre array to 2 arrays of 1 ⅓ plus 2 acres. If buysolar and I do this the dense option of 1070's or 1080ti's would be best for us. I would hope nvidia continues to shift miners into specialty cards such as the ones in your build. This would help keep both the gamers and miners happy. I could see your build with the backplane loaded with a new mining card as it is rumored nvidia is trying to build a card line for miners beyond the one in the review above. I would love to have a unit with 4-6 psu's on the backplane running 16x 1080ti varients using about 3200-4000 watts. Each unit could have its own 20 amp 240volt circuit. No need for pdus since the software allows access to the unit world wide. Oh to all kjs is the person involved with supplying the demo to me. As we continue to iron this out via pm and emails I will hopefully get more details on this item. |

One of my PSUs was DOA, so I've been running 9 GPUs with success until today. I received a replacement PSU and connected the last three GPUs today. ...and that's one hell of a shit storm. I finally got the 12 1080 Ti to be recognized in the device manager but many miners aren't so happy with all of these. I wonder if MSI Afterburner can handle that many cards.  Any advice? ( Other than "just split your cards into two rigs") yes go to the monitor section of msi afterburner. it has a stock setting of 1000 micro seconds so it samples all 12 cards 60 times in a minute. each card has at least: 12 things to look at so 12 x 12 x 60 = 8640 things are checked every minute = a shit ton of lag time unless you have an i7 cpu. so set the sample time to 12000 micro seconds that is only 12 x 12 x 5 = 720 things every minute this will help. if you need a photo of the screen in question I can provide it. |

Interesting design considering most high-gpu count prebuilts I've seen are usually enclosed in a case, and the PCIe switch they're using is full custom and seems to actually work! I'd personally be interested for the exact noise level of the device in decibels and possibly temps. Looks nice and neat on the link you posted to another review, keep us updated!

This is for a medium or large scale setup. Buysolar and I are trying to develop a second solar array in NJ this would be an ideal unit for us. Our second array will be 2 acres and generate 30-40 kwatts 24/7/365 via tie in to the grid (NJ has good rules for this) We can operate it remotely which will be nice since it is about 50-60 miles from Howell, NJ where the 2 of us live. I hope to get this gear in under 1 month. I will run it in my garage meter power use and sound. Do a few videos for my you tube channel. I will then move it to the solar array do another video. Get a feel for power use per sol etc. |

4 billion so 45,000 x 20,000 = ? 900,000,000 they did that in capital gains last year but 45,000 x 10,000 = 450,000,000 loss since the peak 20,000 a coin this happens to be a wallet they have that I know exists.

You can also use a power supply from a computer like I did:  I had a spare one laying around. that works well . just as long as he does not use those bricks he linked |

I have 3 omen pc's that could do 32tb each and mine 2 1080ti's
Is it viable to mine gpus while the pc mines hdd?
you could be on to a good idea.
Yes, 32tb is not an issue. From rough estimation an i7 8700 can scan 50x 8tb drives before maxing out 100% cpu usage. I'm extrapolating my 1950x's performance, which is underclocked to 3.3ghz use 40% cpu scanning 40 drives. I think nows the time to get in early on HDD, all it takes is a whale swiping all <$200 drives. This $150 drive works: https://www.amazon.com/Seagate-Expansion-Desktop-External-STEB8000100/dp/B01HAPGEIE/ref=sr_1_3?s=pc&ie=UTF8&qid=1519479080&sr=1-3&keywords=8tbOr wait for $160 WD easystores, which has 2 year warranty. The seagates only 1 year warranty.
I currently have 417TB online for HDD mining. Plot speeds are good at around 90,000 nonces/min on a dual E5-2660 V4 rig (paid $350 each for ES versions of those CPUs):
And scan speeds are really good:
Takes around 20 seconds to scan 417TB worth of plots.
Those are really good write speeds and no bottlenecks when scanning. ES cpus is definitely the better option. I once struggled for 3 weeks with an Xeon e5 2630v4 ES and evga x99 ftw K. never got it to post, bought 6800k and called it a day. Think I got a ES revision that's too early. haven't dived into ES again, but very cool to see it working. Which mobo are you using? Any rig pics?  Writing over my usb hub only has 40+ mb/s despite there being no bottlenecks. 120mb/s if directly connected to the usb port though.  Img: https://ibb.co/ePqNTHMy threadripper plotting. Underclocked to 3.3ghz. Using 25/32 threads. do you run the hdd mining with or without gpus
I run my 1950x with an rx480 (no choice, need a gpu to post). But gpu is quite troublesome to work with for burst. Plotting with gpu is 2 step process, plot to a drive then optimize to another drive. You can use a software called turboplotter to directly plot optimized for gpu, but then the speed halves... For cpu once plotted it's already optimized. With price of gpus it's not worth using it. Crazydane's ES xeon setup seems like great value, definitely better than threadripper. But an i7 8700 should be easier to work with. Grab a mobo with many usb 3.0 slots, like Evga Z370 FTW or gigabyte Z370 XP SLI, 5 drives per usb3.0 port, cheap 500w psu, borrow 16gb ram and all good to go. When mining just 4gb should do. I have so much gear buying mobos are not something I need to do. I need to explain better I have these 3 pc's I can put 4x 8tb hdds in them. that gives me 96tb for hdd mining I still want the gpus in them to mine zec and the cpus to run the hdd mining  |
