i have a bunch of s4's i have retired , before i threw them in the dumpster i figured i would see if anyone needed anything
s4 stuff
hashboards
io boards
fans
lcd's
all the psus that use pci-e connectors i have kept as they work well for powering s7/s9's
i have the early and late style hashboards
let me know what u need and what its worth to ya
s2 stuff
free if u need it just pay shipping , and if ur nice enough maybe throw me a few bucks just to cover my time to box and ship it
loads of fans
over 100 hashboards
io boards

what are ur starting voltages at ? i have a few sp20's that will not start below .60 , also check the events tab and see if it keeps saying minergate has died or just post a screen shot of what is int he even log heres an example of one of mine were 2 loops wont start below .60  |

Oh, sad too see that  Did the voltage go way up in that situation? Presumably yes. yes input voltage spiked between 350v to 480v at the psu luckily i was able to salvage some of the boards and put together 1 and 2/3rd's of miners out of the 4 that got hit i run 3phase 480 that i split single phases into 277v power , so the system has to stay balanced on all 3 phases ouch.. im hurting just looking at it. what power supply are you using? doesn't it have any over voltage protection? i run a mix of 2880's dell 750's dl580's and a few others like dps 800gba and dps1200's one of the 2880's actually arced across the input terminals , and the other was fine go figure |

just edited the list to move dps-2000bb from working , to working but unreliable
, i have gone threw aot of dps-2000bb in my dc on 277v power i only get about 1-2 months out of them so i dont suggest using them with 277v
i have ibm 2880's that are 2 years old still going strong on 277
.... So -- why -- don't you just pick up a few buck/boost transformers with 32v secondaries and knock the 277v line down to more reasonable 245vac??? They are not expensive. A DPS 2kw supply would need one rated to handle 266VA, call it 300VA with margin. because its just cheaper to run the reliable 2880's or other 277 reliable psus |

Do you have any reliability data on the Dell Z750P's on 277v? i have 4 of those i have been running on 277 for 1.5 years now they are reliable on 277 |

How much for the breakout + psu and fans to run it ?
I have 4 Avalon 6's that would be nice to have all on the same plug + a little overvolt would be nice
price includes the fans , unfortunately i dont have any psus to include. i run my stuff on 277v power instead of 220/240 and the dps-2000bb psus just arent reliable enough or me on 277, the psus would only last me about 2 months on the 277v so when the last pair quit i never bought anymore. im sticking withthe ibm 2880's as they are reliable on 277v power u can pick up psu's from finsky or off ebay though |

its all good man , i have thick skin im not easily offended, it just comes down to 2 ppl trying to get the best price they can. im just one of those ppl who doesnt have to buy at this second and can hold out for a deal which sometimes makes it hard to deal with me
i might still grab it , im going to watch afew more auctions on ebay first , i paid 100$ for my 280x that does 225 so just hard to pay the same for something that does less

what speed does it hash at ? i cant make it out int he pictures with this crappy monitor
stock setting around 180-185 for zec I only do zec with it. pm me ur best price , ur about on par with the price of a used 280x on ebay The lowest xfx r9 280x is a buy it now for 150 + 8.50 to ship. That is 158.50 shipped. My 99 price for a xfx hd 7970 is more then fair. If you want lower check at 910 pm est on Monday I will drop to 98.00 You could scan on eBay and get a good auction deal but that will take time. So if you want it it is 99 until I drop to 98 next ending auctions ending over the next 5-16 hours are all in the 75-105$ range shipped |

well when i break stuff i break it good    though this wasnt actually my doing this is what happens when somone shuts down 2 phases of ur 3 phase power system and the system goes way unbalanced. |

Hi OP, I am kind of interested in getting this service. However, since I'm not that familiar with mining and how this works, could somebody link me to a guide how to use this kind of service? Op, also, can you please publish your rates and how do we do contracts with you.
drop me a pm , this section of the board moves so fast its hard to keep track of threads here |
