No dashes before -- all o's on both blades. And it was hashing fine out of the box at stock freq for a few hours, then I cranked it up to 400 and it was doing about 1.3 TH nicely. But so frickin loud. That's when I decided not to leave well enough alone, and to replace the fan with an S3 push.
Today its hashing on the one blade at 350 freq again. And I can see the S3 fan is not going to be enough. Its barely keeping the one blade at stock clock under 60 degrees...
I did reseat all the power and data cables I can see and reach from the top. I guess a full tear-down is in order. What was the good thermal paste again?

Did you only use one fan off the S3? I don't think that is near enough for the heat. You'd need both push and pulls form the S3. I tried adding just a 104CFM fan to the back of the S5 tonight and use with the stock fan to see if it makes any difference tomorrow after I get a chance to put it in my rig. Should reduce temps enough to warrant a fan speed reduction. We'll see. The fan speeds of the S5 and it's extreme heat generation IMO is a downer on this. My SP20's create less heat at much quieter fan speeds. I was hoping to rock a few dozen S5's but I might have to just buy more SP20's unless I find a decent way to quiet them at least to SP20' levels..  (I run my rigs in one of my garages under the house. Can't hear it inside, but it's quite loud and toasty in the garage.) **Love a heated garage that kind of pays for itself**  |

Ofcourse, you need tools (that's a no-brainer) ... a dremel would be a good start .... but definitely not a task to be undertaken by feeble minded at DIY. But like I said, not that hard (does not mean it is easy!)
 Having worked at my family's machine shop, programming CNC mills/lathes and Wire EDM's for a few years, if you can do what you're saying with a dremel and have it actually work, I'm sure we ALL would love to see that. On another note, to do it properly, it is not financially feasible for a few extra GH/s, considering the time and costs involved. That's like saying you want to add 15HP to your toyota corolla by spending 30-50% of the value of the car itself and only gaining about 4HP at the end..  |

.... I wish a company made a copper option with heatpipes, could make a huge difference for overclocking.
Should not be that hard to fabricate on your own .... just need to find out what thickness of the copper slab to get, slice some slots / channels in it and then split a few copper tubes to for the fins that are slid into the slots. All you are left to do is drilling tapped holes for attaching the PCB. I wonder how cost efficient it would be though for just a handful of units ..... ? Doesn't sound that easy to me. Unless you have a machine shop and all the tools necessary as well as the skills to do properly. |

Sweet. So I more than doubled my rental cost in less than 5 days. I'll have to do this on a weekly basis. LOL. Helps the pool too. No don't do it for at least 2 or 3 weeks. this is an exceptional run of luck. Wait for a 300% or 350% block and then do it. It may help to change the luck when the pool needs it. Ok. I'll do that then. Until then. More of my miners have arrived and I'm aiming them at this pool. |

Guess I got luck too.
Rented 300TH for 3 hours at 0.49BTC (Pricey, I know), but it already hit 6 blocks and the 300th has still not left my shifts. I think I still have 1.5 or so days left before it falls off (If I understand it even remotely right). LOL
ps. It earned me 0.873895753BTC. If we hit one more block tomorrow, it has doubled itself in 5 or so days. Not too shabby.

How do I manually update the firmware on an SP20E? I can't find the download anywhere on your site. (Spondoolies).
I have 2 that are using the 'latest' Firmware per the webgui, but it's using cgminer 4.7.0 still and westhash doesn't seem to work on those.
All the others are 4.8.0 with the same firmware revision. Weird.
 go back to manual firmware load and show me the choices it offers  Thank you. I didn't think it worked that way. I selected the 2.6.14, did the reboot but no changes. Cgminer still shows 4.7.0 . Should I try the test versions? Bump. |

Awesome. Since hitting the pool with the 300TH 77 shifts ago, I have got 5 blocks, about 0.715BTC. Already 40% profit and my shifts are not gone yet from that rental. Nice Job! |

How many shifts before any hashes disappear? My 300TH rental is still well up there and has paid more than it's cost already with the 4th Block found since I hit the pool with it. It's at shifts 76 or so right now. How many more before it is not used anymore? Is that what the 130Hour Plus thing is for? Also, looks like Westhash has crashed since their prices went up yesterday. All my miners went to secondaries a bit ago and westhash's price is in the toilet again. |

I'm starting to think these miners should have been what the C1's were.
They run with that open-built extremely loud full speed fan and still are over 50C.
Even the SP20's at Fan speed 50 are more quiet than these things.

The variance in hash rate is normal across all miners IMO.
I have 10 SP20's that have a 10% variance across the board. A few need more juice to get to the same spot as the others, or less hashes to consume the same power.

Have the firewall on a nightly reboot. Unless you're using a Sonicwall or other pro FIrewall/router you need to have them autorestart at least every couple of days for optimal performance.
Cisco ASA, so that is probably not it. Uptime isn't a problem for the ASA-- sometimes I wish it would die so I could replace it with something more friendly, but it just keeps on going! Yeah that should be ok. Although I've seen SPI on those cause issues. |

Last night I had a dream that my miners were down. It turns out it wasn't a dream-- I woke up this morning to a dead Internet connection and 9 shifts with 0 hash!
The bad part is I don't know exactly what happened yet. The problem was on my end-- my firewall became unresponsive. This morning it was unpingable and every switch port was flashing away like crazy in unison like a broadcast flood. The only thing running during the night was the miners so nothing should have set off a broadcast storm (or whatever appeared like one), nor has it ever happened before. After power cycling the firewall everything returned to normal. I'm left scratching my head as to what happened (and worried it will happen again).
Anyway, my 6T is back.

10-4, soy. I will post back if I have to try the reset.
I am moving my internet hard line into my home office tomorrow.
If I still can't locate the miner on 192.168.1.98 or 99 on my hardwired 192.168.1.1 router then I will reset.
I want to try to narrow this down before I re-boot the miner.
Thanks for all the replies!
I had to hard reset a few S3's and a C1 before and all it took is push the button, count to 10. Power off, push button again for 10 seconds, power off and after it comes back it's factory reset. |

Okay I rented for 100 shifts of hash
5 at 100th
94 at 10th
1 at 200th
I paid in .572712 btc
0.10886129
0.10901577
0.07543100
0.06897737
0.03443683
0.03192053
0.42859279 paid so far.
I have a payment coming for .11 and I have about 4 days left to collect if we hit a block or 2 or 3 .
I need 1 block more for a certain profit.
Nice! the pool luck has been great even with us dropping under 2PH. I love that my payments have almost doubled lately while putting in the same amount of work  Well... Not quite that good, but still decent. Don't forget it takes longer now to solve blocks on average. |

What does the 'Network' time counter mean?
That is the elapsed time since the network found a block. Duh. Never figured that pit. Lolol. Thank you. |
