It appears that the primary Spondoolies thread is now unlocked. I just posted to it a minute ago.

Anyone care to comment on how/when this thread got lockaed, and no unlocked? Seems odd. I am guessing it was a mistake, and probably not by Spondoolies.

Has anybody set a static IP address for their SP20? I found the "Network" section of the Settings page. As you would expect, the "Use DHCP" box is checked. When I uncheck that box, all the usual items for the IP address and other usual IP addresses on my network are set as you would expect from when it got them as part of the DHCP exchange. I then just change the miner IP address and leave all the other stuff as it was since it's correct. I hit the "Save" button. Nothing obvious happens. When I do anything else, the Netwrok essentially reverts to "Use DHCP".

Is this something I need to do via SSH, or am I just missing something on the Settings page to actually make it "stick"?

Take the answer from Spondoolies, but as I understand it, 2.6.14 is more recent than 2.6.7. Hence 2.6.14 has additions over 2.6.7, and not the way you describe.

What I have never understood is that if you have a single  "large" miner (e.g. an SP20), and then decide to provide multiple pools to it, doesn't that just appear to be "pool hopping" at the whim of the mining software?

I have routinely mined at Slush. It always seemed to me that if I provided a "backup pool", then as soon as there is a hiccup with Slush, then as viewed by Slush I have "pool hopped" off to wherever. This seems to run counter to the "don't pool hop" strategy.

I completely understand splitting up multiple miners amongst pools, but I've never had enough hashpower to make that beneficial it would seem.

What am I not understanding about multiple pools here?

So presumably Lee doesn't have a $45 shipping cost, and his hosting deal should be $369 for the S5+PSU, and then his usual daily hosting cost? Has this been confirmed with him? This would mean that is was only an effective $29 increase over the original $340 cost for the S5+PSU. Not bad if correct.......

Assuming this is legit, it seems like a possible alternative to Lee's S5 hosting deal in China, particularly for US based miners. The $399 price for an SP20 seems quite reasonable, and a termination/shipping fee of $50 is a little high, but probably no worse than what it would cost to finish up at Lee' facility. Lee has a significantly better daily rate though.

Could Oregon Mines set up one or two SP20's with the "downclock rate" (i.e. 180W on the 4 loops), and report what the hash rate is after several hours?

I think I spoke for -1.26 to -1.50%.

For such a facility, is the hosting cost a fixed amount of Bitcoins per month? Or does it vary each month, presumably with the price of Bitcoin?

It seems to me that if you are the kind of person that calculates ROI only in terms of Bitcoin, it makes no sense to just buy and hold Bitcoin. No matter how much, or how little, you pay to purchase N Bitcoins, that's exactly what you'll have 1 year from now (i.e. N Bitcoins). In that case your return on investment is actually zero, since you neither gained or lost anything (as measured in Bitcoins). You strictly "broke even" as measured in Bitcoins.

Not quite sure why "last Batch of S5 production" is good news, but I would also take the statement with a grain of salt. It's the last currently planned batches. They can change their mind for any number of reasons, primarily for what's in their best interests. I expect that the statement is there as much to encourage possible buyers to buy them now, and not wait. I expect they want to make sure they don't have any S5's, or specific S5 parts left on the shelf if possible.

I'll take -1.26 to -1.50%

I'd swear I recall a member called "lightfoot"? He seemed to be doing serious work on various generations of BFL gear, including Monarch repair. I think you can search for him, and see if would be interested.

I am pretty sure you'll need to contact Spondoolies. I think the controller is actually "Beaglebone Black" centric, and has an FPGA on it, likely for connecting to the hash boards, and/or the fan.

You might also try the "Maketplace" forum and see if somebody has an SP20 that's dead for a different reason, and would sell you the controller board. I'd try Spondoolies first though. Since it's coming up on their weekend, give them time to respond.

I think you'll find that 1.4Th is pretty good for an SP20. You might well get another 150 GH/s, but it's generally felt that the advertised number of 1.7Th is generally not going to be realized. The basics for maximum speed are all the "Settings" tab. I don't think there is much magic beyond setting the "Voltage Limit" to the 0.790 value, and the "Max PSU" value to 288 for each of the 4 loops. Obviously the Fan then needs to be at 100. I have  seen a "Basic Settings" button that then lets you choose from 3 "combinations". There is one combination called "Turbo Fans, Highest Rate". While I haven't used that, I would bet it just maxes out the values.

Make sure you have a high quality power supply setup (1200+ Watts) with 4 high quality cables and PCIe connectors. The quality won't influence your rate much, it's just important if you don't want something to melt. Also make sure you have a cool environment (say 15-20C), cause everything will get warm.

Don't forget the ear plugs, but I expect you know that already.

One thing that isn't obvious is that the fans for the S5 and the SP20 seems to require a fair amount of static pressure to get the actual colling effect. The CFM (volume of air moved) isn't the only consideration as I understand it. You might find a higher CFM doesn't actually yield the result you expect, because it doesn't have a high enough static pressure.

Based on some of the comments here, some folks might consider $700 too much!!!

You'll want to capture the result of the "ASIC Stats" page and post it here, and/or possibly under the primary/official Spondoolies thread.

I think it actually is worse. Even if the electric company, and landlord, and employees, accepted Bitcoin would they want a 50% "pay cut" after the halving? As a miner your production of blocks remained the same, you just get 1/2 the reward.

I have this mental image of the "farm manager" going home on Friday, the halving happens over the weekend, and then he returns on Monday to realize that his "gold mine" has been reduced to a "trickle". Yes this is an overly dramatic view, but I can't think of a single other industrial enterprise where that kind of thing happens "overnight". I expect when the halving approaches, things will get crazy in the mining business.

Looks like the "0% luck for a day" has finally come to a close at 27+ hours. That was BRUTAL!!!!
