Also, anyone have the exact time it went down?

What will happen to all our rented hashes?

Ahh... thanks. Mine is 508,000,000 |

What does the 'Best Share' mean anyways.?

right. it worked when i tried it so somethings changed since we added nicehash support. or westhash is doing something weird. can i get the rental id of that westhash rental so i can see whats wrong with it.
Ahmed
It's on any SHA256 rental. I have changed pools after seeing it not working with westhash, as I'm not a fan of losing money on a dead rental.  |

So, the z750 supplies work under heavy load. Typically a computer supply will claim a certain wattage capability and on the side list the current available on each voltage but don't supply that total wattage to any one voltage.
In switched mode, the z750 has a single rail 12v @ 62.4A which equates to 748.8W. In standby mode it is 3.3v @ 5.5A which equates to 18.15W Okay I was looking at this as it seems to be similar: Abstract from google listing: COMPAQ PS4060 750W. HOT SWAP POWER SUPPLY. + 385V. 660uF. 100-240Vac controller. Primary board. 3.3V/ 40A. 12V/ 25A. ML4824-1. PFC / PWM .. http://members.home.nl/a.k.bouwknegt/index_bestanden/Diagrams/PS4060%20single%20line.pdf------------------------- Are you sure the single 12v rail is suppose to supply 62.4A? Are there other voltages? I stand corrected. I picked up my Dell N750P-S0 today and it clearly states12VDC 62.4A and 3.3VDC=5.5A. --------------------- Have it powered up and seeing 12.20vdc! --------------------- Connecting to the new supply - I could solder here but the lower flat washer makes contact with all three connections: https://drive.google.com/file/d/0B_DLmNkCkkVpcjc4ZUduYmM3dUE/view?usp=sharing-------------------- Tested an older miner the other day and it was 368 watts/281GH/s @ 12.0vdc with 2 of my cheap supplies (<$25 ea). Am running the N750P-S0 to the same miner, 372 watts/285GH/s @12.2vdc ($17.96 w/free shipping). Told you they were great power supplies for the money. You can buy them dirt cheap, I'm just lazy and use a breakout board with 16AWG PCI-E cables on mine. |

Heheh. Sorry if I got out of line, but the reply seemed warranted.  On that note, it still doesn't work. |

Any idea when the issues with Westhash will be resolved? Any time westhash's rate is high I can't switch my rentals over on betarigs as it says you guys are still having issues.
IMO you guys are losing out on a large amount of rentals when people realize they can rent for 30% below payrates with westhash.
Fix that please ASAP.
Also glad the graphs issue is being worked on. On most PC's and tablets it is just way too slow on rendering the graphs. Heck even on a high end PC it is slower than anything else... EVER. (Tested Using IE11 or CHrome)
Hi thedreamer. This was fixed quite a while ago. EDIT: It was enabled but on the user profile page with mass update it wasnt enabled. I've enabled that now Ahmed I tried it just about 2 hours ago and didn't work. The hashing stopped on the rental rig's when set to the westhash pool. Set it back to another pool and they started working again. |

Hmm... sometimes = yeah...   |

Anyone have experience asking spondoolies to ship the miner from their USA datacenter? It's been 10 days since I paid for the shipping and the miner is still in their hands, and plugged out. That's $120 out the window. Unacceptable tardiness.
I remember back in the USB miner days, one guy I bought a Block Erupter from offered to mine using your pool info until your miner arrived. I thought that was quite reasonable offer, and a real inducement to buy from him rather than somebody else. You think you clear $12/day with an SP20 in profit? I am surprised by that. The SP20's I've been buying from members on this forum have all been running until they shipped on my pools by the sellers. (Thanks to all again) which IMO is a very nice thing. An SP20 per day running at normal speeds (let's say 1500GH/s) should earn you about $3.80+- a day with FREE power. |

my miner keeps disconnecting from this pool..
looking at the stats it seems 100T or so just dropped out.
Problem is between your miners and the pool, and usually it's a routing/network issue. There is nothing wrong at the pool end. If you have linux I suggest you try using mtr to diagnose where you may be losing packets. 10% loss at the last step is normal. mtr --report -w solo.ckpool.org the hash is back and my miner reconnected, it must have been comcast then.. it was down for about 5 minutes. I lost connection too. The miner connecting is not on Comcast. |

I think there are no bites because that's the same price as brand new retail. Just FYI.

I just rented 10 TH to throw in and hopefully help break this damn block.
maybe it will do better then the 1ph I tossed at it last nite. (only for just under 2 hours About .5btc worth of rentals) Wow. How do you get it so cheap? Hook me up bud! |
|

Daym man. You're almost at 1 PH!! 1/2 my miners are rented out at betarigs, so I'm down. |

Wow man, you are waaay overthinking and building your power supplies/usage. All you need is one Dell Z750, breakout board, cables and done. It can power 750W at 90+% efficiency for ever. They are VERY robust. I run a few SP20's off them underclocked at 600 watts, but have tested them for a few hours with no issues at 900W, even peaked them at 1000W by accident at full speed. You can get the Power supply for around $20, the breakoutboards for under $30, cables for a few bucks. NOTHING ELSE NEEDED. On another note, the C1's are only worth using if you have cheap or free power, or if you want the quietest system possible. (I will be running a few in my office after my $0.779 / KWh price kicks in in a week.  Until then, I don't use them constantly. I use mainly Spondoolies, as IMO they are the BEST miner on the market. Bar none. |

Okay, in the post he says the most efficient test was 575-590watts, 804-817GH/s so the best would be (575w/817GH/s) or .703w/GH/s. The 1008GH/s test doesn't show a wattage. His highest frequency test 1123GH/s drew 943watts or .839 w/GH/s.
Wish he had provided the watts at stock settings but yes, these are good numbers, better than mine.
I thought I did, but stock was 1008 / 802Watts @ .74v The best was 805-821GH/s @ 575-600 watts between all 3 C1's I have. After that they start sucking Juice like my 3year old . I stopped using them as I'm concentrating on much more efficient miners for now (SP20's / S5's), but in a few days my $0.0779 / KWh kicks in and I'll put them to work in my office as they are quiet as heck, so the quiet factor I agree is much better at the trade off , of low hash rate/ high power usage. On the other hand, now that I think of it, it's like an Avalon 4.1. I think those go down to 800GH/s @ about 550 watts and are very quiet. Almost the same I guess. I'll have to try one. Okay. So, $0.0779 will be your power cost. Down here where it will get hot this summer my bill shows power to cost $0.075 but when I add in taxes but not line charges I see $0.0805 but it's not all that clear with their adjustments. I worry about the heat damaging the ASICs. To be honest, using the Kill-A-Watt, I don't see a big deal in cost savings when tuning for lower energy but I haven't tried the big jumps down. Interestingly, with your numbers for C1 run at almost stock frequency and voltage, your 1008 / 802Watts @ .74v, compares well with these I took: after 1 hour at 250M/0760 I had 1008.57 / 818 watts for .811w/GH/s but the same unit at 2 hours showed 1002.88 / 819 watts for .816w/GH/s. Ambient was 80°. So reading of 802 watts is 98% of my 818watts. That's only a 2% difference in supply efficiency. I'm using four 360 watt LED power supplies each modified with a heatsink added to the bridge rectifier, the one turn pot changed out for a Bourns 3299w-501 500 ohm trim pot that has, what, 20 turns from 0-500 ohms for more precise adjustment of the output voltage, and each supply has added a 6 amp 120vac line filter (reducing noise so it doesn't disturb my TV watching/recording), but, each supply costs under $25 with free shipping. Each supply drives one blade. I don't put them in parallel anymore as it's easy to burn one up in parallel. Then again I had to build my PCIE harnesses. Also I add 4 digit LED voltage readouts to each as it's easier to tell if there's a problem. Downclocking gives you 11% better efficiency. Since we're all working on small profit margins that is worth it imo. Also all that work and gear to power 1 c1?!? .. Why?? Not easier and cheaper to buy a Dell z750+bboard+cables for like 50-60$ and be done with? |

Purchasing the 24 S5. $3500 has been sent as part of the upfront payment.
U got a good deal bud. Dang it. Lol That is only part payment. I know, but as far as I heard from the seller, I was #2 in line for the whole lot, so I know the price. |

Send me pricing in pm Plz.
Looking to buy a few, USA only. Prefer face to face in the northeast.
Thanks
