i reversed the airflow one of my sp20, temperature was very stable 23 / 29 27 with the 0.627v and 950ghz (underclocked), noise also bit low now as i think 5-10 db low

Has anyone found a 120mm fan they put on the other end of these and find it helps at all? although sucking is one option, I'd think a two fan approach would drive even more airflow?
why do you need more air flow? are you looking to run this at 1600gh+ ? Thinking more for noise, and cooler is always better if I can get it down. |

Has anyone seen an entire loop on one of their SP20s constantly disabled? LOOP[2] OFF TO:0 (test serial failed)
4: disabled (no power to DC2DC)
5: disabled (no power to DC2DC) And if so, were they able to remedy it without sending the unit back to Spondoolies? I've tried rebooting, power cycling, trying all different versions of the firmware, disabling each ASIC in the loop one by one, etc. I tried contacting support@ and they referred me to their Skype usernames...which is difficult to catch them online due to the time difference and their availability. 22/02 19:23:54:Loop missing in discovery 2 (code 5)

move the cables around to see if the problem follows a bad cable. try another psu. try a middle clock not real low not real high. 0.63 0.63 0.63 0.63 0.635 |

 The power supply is a Seasonic SS-660XP2 platinum, which comes with 18 AWG pcie cables (I thought I wasn't skimping  ). Although it appears the modular connector itself failed rather than the wire. I'm using 2 of these power supplies per SP20, with each PCIe power connector connected to its own separate cable from the power supply. I guess I need to dial down my voltage/power settings from the factory defaults. Temp Front / Back T,B 31 °C / 78,74 °C
Fan Speed 100
Start Voltage 0.69 / 0.69 / 0.69 / 0.69
Max Voltage 0.75
Max Watts 288 / 288 / 288 / 288 Power is cheap so I wasn't worried about efficiency, which is why I didn't change the settings any. Seems those are too high for the PCIe power connectors. Isn't the 6-pin PCIe power connector specification 150W max to begin with? |

Anybody know gauge the cables are for EVGA G2 power supplies? They are red, and sleeved, with nothing to indicate 18AGW or 16AWG. This seems to be a risk associated with use of the PCIe standard way beyond it's original intent.

Just wanted to let everyone know that the SP-20 Jackson is confirmed out of stock and out of production by a Spondoolies-Tech rep via email. Transcript below: Dear XXX, Thank you for your e-mail. As you know, due to high demand the SP20 has sold out. In order to focus on the SP31 and our next generation of machines we will not be manufacturing more of the SP20. We do offer the SP31 which at 4.9 TH/s is the most efficient miner on the market today. It is very attractively priced at $2075 plus shipping. For more information and to order please visit our web site at http://www.spondoolies-tech.com/products/sp31-yukon-shipping-from-stockPlease check back on our web site at www.spondoolies-tech.com periodically for product updates. Regards, Barbara ------------------- Kind regards, Spondoolies Tech Support To me, this means a few things: A) SP-20's current, used aftermarket price should not depreciate much (if at all.) B) Used/New SP-20 + PSU bundles will soon be hitting the market from third-party vendors or re-sellers. C) A more efficient miner should be about to hit the market relatively soon c-1) (The theorized) SP-20's bundles would drop in price once the new products are released. WILD CARD: Difficulty rate is ridiculously high when the new products roll out. The margins would be so low for miners that hardware costs should keep dropping. Stay tuned for the rumored SP-50. (don't hold your breath) |

the evga 1300 g2 are 16 ga. I have never had an issue with them. and I will say running the gear beyond a 240 watt is risky I set mine at 200 and underclock. |

(don't hold your breath) Access to the latest techmology is the home miners biggest dwawback as there is not much incentive for manufacturers to sell them retail. Bitfury and knc are pretty much private companies now self mining. Asm is shareholder amd investment vehicle so is wolf. Spindoolies is comcentrating on wholesale. Bitmain could be next. Everyone is saving limited resources and moving to shared or cloud mining. |

Thanks. That's a good idea. Since WestHash is closer to me, here's how I've configured my pools now: westhash.com p=0.0159 nicehash.com p=0.016 kano.is f2pool.com antpool.com Looks like I'm all set. At least until the next difficulty change and I have to recompute the profit constant. Of course what we need now is some event to drive rentals through the roof, like what happened with Paycoin  yeah but sometimes people do all the hash at a top rate for ½ a day you will pick up on that every time now. philipma1957, I've got more thoughts about pool strategy. I guess I'll continue the conversation here, unless you think we should create a separate pool strategy thread. I've had fun with the above pool strategy, but it's been a bit harrowing being primarily on a high variance pool. If it wasn't for that fairly recent string of insane luck on kano.is, I'm not sure if I'd be ahead. I know that everyone says that variance doesn't matter, long term. But if you're gunning for a short term ROI (relatively speaking), it seems like low variance is critical as difficulty goes up. As the difficulty was floundering up until recently, I haven't stressed too much about variance and have been playing on smaller pools. But now I'm 80 days in with my SP20 and about 75% of ROI, and the difficulty seems to be rallying a bit. So rather than gambling on smaller pools, I'm thinking of going the conservative route of low variance until I hit ROI. The problem is that I don't like contributing to the dominance of larger pools. So here's what I'm thinking. I'll set NiceHash/WestHash as the primary, but with a low profitability threshold. I'm thinking about 1% over nominal BTC/THs/Day. With a 2% NiceHash fee, basically this means I'm agreeing to lose 1% over nominal to mine there, which seems fair. Then I'll set up f2pool.com as the secondary. The idea here is that as long as NiceHash is doing slightly better than nominal BTC, I'll mostly be mining there. This way I'll capture nominal profits as well as any upticks. And when NiceHash is in the dumps, the miner will revert to f2pool.com. Sure f2pool.com has high fees, but if it pays for every submit that means that the fees are the only cost of frequent bouncing between NiceHash and f2pool.com. I'm hoping that by mostly mining on a rental site, I'm effectively contributing to decentralization (hopefully), while enjoying lowering variance. How does this strategy sound to you? |
