so I got my hands on a few cheap metered APC pdus : Input: 208V , Connection: NEMA L6-30P , Cord Length: 12 feet Output: 208V , Connections: IEC 320 C13,IEC 320 C19 I have an electrician coming in to wire to new cicuits for and he said this : Now, are these dryers and or ranges you are installing? Do you have the model numbers? The old 3 pronged outlets are grandfathered in for repairs only, but for new installs you need (and probably want, for increased safety reasons) 4 prong outlets. This requires 10/3 wire (which has 4 conductors) as opposed to 10/2 (3 conductors).
my questions to experts here : -the NEMA L6-30P is three prong, but really only good for pdu's and computer stuff, should i let him do the 4 prong outlet and look for an adapter ? -I don't want to pay another $100 for an adapter for each outlet. he said something about buying pigtails from APC to convert the outlet but that looks expensive. -Anoying thing is do wire up the NEMA L6-30P, seems to require a permit pull which i don't want to pay for. There should be no problem installing a NEMA L6-30 outlet in a home or business without a specific permit. The outlet is about $50 and the wires to your fuse panel maybe $3/foot. Circuit breaker is about $40. If it's a simple run without cutting holes in walls or running wiring through tricky spots it shouldn't be any more than $350 installed for a 30ft wire run. If he quotes higher get someone else to give you a quote or do it yourself if you have basic handyman skills. (remember electrical safety rules and shut off the main panel before touching wires) Yeah your right he quoted me $325 using his breakers , the outlets were around $19 a piece the wires were expensive though I had to buy 100ft since they run in 20 50 100ft increments. We will see how the install goes today and thanks. |

I only like eligius becase they allow merged mining and no fees, but yeah i think ill move to multipool.us
Sorry, never heard of that one.. merged mining? Please explain. Merged mining is when you submit answers to multiple blockchains. In eligius's case, your proof of work goes to solving in both the namecoin and the bitcoin blockchains. Interesting... I will send you a PM regarding this. Correct . so you basically are mining two coins at once. You are supposed to get payouts for both. |

One week for the Group Buy orders is over. Would be nice to compare some pools and or different travel times to the Data Centers. Till now I mined only 0.5 BTC in P2Pool... First day hosted in ST DC. My shares and the pool luck sucks these days...  I feel you pain I'm currrently mining on eligius.st and even though my expected payouts are supposed to be : Your approximate maximum potential earnings at the current network difficulty of 27,428,630,902.26 and maintaining your 3-hour average hash rate of 3,991.63 Gh/s is 0.07318811 BTC per day. I'm barely pulling in .045 BTC per day using 2600 watts might need to switchp pools Yes I am pretty sure you do... it is close to what you are suppose to be getting but should be getting over .050 I only like eligius becase they allow merged mining and no fees, but yeah i think ill move to multipool.us |

I received my 2 x SP30s yesterday, and installed them in my quiet rack cabinet.
These are impressive units! Definitely the "Big Boys Toys" of the Bitcoin mining world.
I got them all hooked up, and they were up and mining as soon as I logged in and entered my pool details. Damn, that was easy. I hung around for a while watching them, and stressed myself out a little bit when they stopped mining. I should have just walked away and left them to it, knowing that they do a series of performance stress-tests to find the optimimum operating speed before PSU/ASIC failure. Sure enough, they settled down into their optimum groove all by themselves, probably still adjusting as they have only been running about 16 hours so far.
These bad boys are the rockstars of my collection. Hash rate at the pool as at 16 hours:
SP30A 4.5 TH/s
SP30B 4.4 TH/s
On my to-do list:
* Upgrade the firmware to the latest version
* Install the rubber feet. I think this might reduce vibration noise.
In a couple of days if you would be kind enough to tell me how much BTC you average daily, I would be grateful. no need to wait, you can plug in numbers here and see BTC/day http://www.bitcoinx.com/profit/4.5Th=0.1147 BTC/day (right now) erm your only making $52.46 per machine in 24/h you spend $7790 6000 watts will be alot per day to run and your expecting to make a profit?  ?? I think we are just looking a break even on this hardware with BTC prices at the current level |

The noise is killing my roommate in the basement as well , I think ill work on getting it shipped to you, how much will it cost to ship from Minneapolis.
$52 UPS Ground, $132 3-Day Select, etc. 18 kg. Contact orders@toom.im if you want a shipping address. The PSUs are also much louder on 120V than on 200+V. Lower efficiency means more heat, which means faster fans. You could also reduce the noise by putting them on a 240V line. how much would you need for the hosting up front ? |

Is it ok to turn fans down from 80% to like 60%
That depends on the intake air temperature. The chips should throttle before any damage can be done though. I think much of the noise comes from the PSU fans, but I might be mistaken. True. Try 70 and see on asic stats page. If asics or dc2dc get too hot return to 80. The problem is I dont remember what is too hot for dc2dc, but under 100c is definietly not too hot. Thanks for the tip I tried 60, the miner seems slighty louder and temps are around 86 85 also increased the voltage from .76 to .79 to see if I could get more hash rate , seems to be stable at 4050 TH Also noticed a new firmware build , what is in it and should I update the miner ? Edit @Zvisha is there any way I could up the max wattage setting to at least 1200 or so ? |

is toomim up for ...sam?
will be interesting to see how it plays out
I don't understand this question. Is it possible to have a drop in the sp10 hosting fee ?
sp10 3 month = 600$ => 1050 Watts => 0.57 $/Watts/3months
sp30 3 month = 1200$ => 3000 Watts => 0.4 $/Watts/3months
We at Toom.im host SP10s for $390.60 for 3 months. By the way, an SP10 uses about 1390W. The 1050W figure is the DC rating of the power supply. SP10s are typically run at about 1250W, or about 20% above their rating. (Emerson, the PSU manufacturer, approved this.) When supplying 1250W of DC, the PSU uses about 1390W of AC, for an AC2DC conversion efficiency of about 90%. Right now the box is hashing on egelius at ~3989 TH VOLTAGE
119/120 front temp 20c rears around 60c
In settings it seems the default watage is capped at 1300 or so on 120v
I wont tweak anything for a day or so to see what hashrarate I can get from factory settings
Anyone have any tips for 120v perf tweaking?
3989 GH/s sounds about right for 120V. I was able to get better hashrate on 120V when using 2. 2.28. I got the performance of my SP30 up to 4150 GH/s on that version by tweaking the PSU limits manually. Zvisha hard-limited the PSU performance to something like 1100W in later versions of the FW, so even though you see 1300W on the settings page, you're not getting it. On the next difficulty (27B), the extra 500 GH/s you'd get by running on 200+V would earn you about $137/month. This is about half of our hosting fee at Toom.im, where we use 254V. In order for hosting on our 254V to be a worse deal than running it at home, you'd have to get your electricity for less than $0.07/kWh, and you'd have to have free cooling and not have the noise be a problem at all. The noise is killing my roommate in the basement as well , I think ill work on getting it shipped to you, how much will it cost to ship from Minneapolis. That also sucks that the psus are limited that way though. Edit: Its doing 4100 th now 120v |

All in all people really understated the build quality of the hardware and software
I looked at the logs and saw the code where the miner tests each of the 29 asics running them
Through a battery of voltage/high/low freq tests and have to say wow @zavisha is amazing.
The hardware is so clean and compact I can even forgive the shipping delay now even if it only
Breaks even just the chance to play with hardware and software so meticulously designed was worth it
Great job sp tech , ill definitely use my coupon on an sp31

Had to go to FedEx depot to pick it up they had to search the truck and they found it yay!
btw what's the default IP address on these ? I have a ton of devices don't know the IP
try with hostname myminer.io the IP is on DHCP .. or get a network scanner app on you phone  cleaned out all my DHCP resevations and limited the amount to 20 so I could see when a new one got request and still nothing. It seems that the SP30 is not requesting a new IP , how do I reset the box ? hard reset worked punching the button on the front |

Mine going to Toomin Bros, delivery confirmed by FedEx for Thursday 28th August ... thanks to everyone at Spondoolies, it might be the last week in August, but you have kept to your schedule, appreciated.
In other news, we also received our first X-3 today. The customer paid over $5k for this one in November, expecting a February 24th shipment date. One of the hashing units is only running at about 700 GH/s instead of 1.1 TH/s, probably due to a heatsink dislodged during shipping--I'll try to fix this tonight. Each hashing unit has a touchscreen LCD on the front running Android. You can literally browse the web with your mining rig. It's mildly amusing. Each hashing unit hashes at 1/4 the rate of an SP30 in 50% more space while consuming about 25% more power per GH/s. But hey, at least they shipped. I was close to pulling the trigger back in December on these BA units I had an order for 20 X1's but cancelled it due to not being able to get the funds in time to meet batch 1 lol ! how lucky am I. I did go ahead and buy near 10k worth of GPUs for scypt though to increase my farm. : at least I was able to recoup those via eBay after they stopped making me $$ |

So as the weekend is here, I guess it's safe to say that my GB unit will not ship in august after all, as repeatedly reassured. Not that a few extra days really matter, but it is a bit disappointing. ST's word have lost a bit of credibility as far as I'm concerned.
Don't feel too bad : Dealt with this crap on my SP30 order the item shipped from Israel to the US in one freaking day and has been help up in customs for two days. I had to email what is called a customs form 50 with my taxID/SSN and address. Basically information they already had. Then the FDA decided to also hold it another 12 more hours and the finally released it at 3.30 am today. Guess what lass a$$ FedEx now tells me it missed the morning sort even after they had already got the clearance at the 3.30am release. So now I am looking at a Tuesday deliver for an item that was shipped with $300 two day intnl shipping. So no hashing for me over the weekend before DIF goes up to 27k that's almost $240 in lost fiat earnings basically .5BTC I could have earned. I asked them to request Saturday deliver and still have heard nothing yet WTF. FEDEX sux!!! Either I will contact billing over the weekend and bitch and moan for a refund or something on the shipping and then try and get it credited to me by the hardware vendor. long short calling FedEx is a waste of time they do stuff at their own pace. I already knew they needed this info on Wednesday and phoned in the info , requested the form etc. but they still did not submit anything until the person that processes international orders in Memphis TN (stupid lazy southerners) called me at 8am Thursday to tell me what I already know : my item was being held by customs. and that the needed the import form. I emailed it to her within 45 mins and she claims she submitted it but the item was not released by customs till 3.30 am. Its a clusterfuck bro, if not for the rising DIFF I could handle it in a relatively sane fashion but like the rest of us I'm in a race against time to ROI. |

Greetz everyone.
I'm in the United States.
After 4 months of having a paid in full status on KNC's website for my batch 2 Neppy (even though I requested a refund, they still shipped) I get this message yesterday from the UPS Message center:
"UPS DELIVERY Exception Reason:
A VALID TAX ID OR DEFERMENT NUMBER IS MISSING AND IS REQUIRED FOR CLEARANCE. WE ARE WORKING TO OBTAIN THIS INFORMATION. Exception Resolution:THE PACKAGE IS AT THE CLEARING AGENCY AWAITING FINAL RELEASE."
Does this mean that I have to have a Tax I.D., go to UPS & pay taxes which is even more money than I already paid $10.2KUSD? If so, lesson learned. Never again.
Does anyone here have this experience?

wow its in Memphis already , cant help but be excited to receive it now even with the lower hash rate : This is my first bitcoin miner after mining scrypt the last two years.
wow spoke to soon just checked the tracking and saw this : Clearance delay!!! Shipment requires importer's registration/identification number for clearance. (Examples include EIN, SSN, VAT, GST, RFC, etc.) what ? Well you get something imported from another country. So it needs clearance. What exactly is needed I don't know for USA but somebody that has done the process can help you. You should just call DHL, provide your tracking number and ask what they need. So I took your advice and called FedEx and gave them my Business's TAXid (EIN #) as well as my phone number. I hope that's enough ugh I don't want t wait till next week. |
