this thread is too long but I saw an advert for an sp20 while I was on wemineltc. I would buy one of them. So is there a group buy for the sp20.

Not yet AFAIK
Sp-20 could be interesting, but i already have more than 2.5 kw.

I would sell my 2 asic miner tubes . the sp20 is finally exactly what I want from them spec wise.

I have 2x evga 1300
I have 1 x evga 1600
and I have 1 x seasonic 1200 watt plat.

I would love to get a decent deal on some of these. of course a preorder for OCT 31st shipping and 119 to ship one truly is a joke.

at 1309 and start mining it today shows a 255 usd loss using 9% diff and 480 usd a coin

A question to spondoolies:

I ordered Sp-30 (September batch 1) and payed for it in the first half of June.
I already asked shipping and got no firm date for shipping in response, which is strange.

Did anybody else received their September orders?

I have had similar response when I asked as well. Be nice if we could get a more firm answer. I had hoped Sept batch 1 meant early Sept, but I should know better by now I guess.

Each of the 4 PCIe connector power 2 RockerBox ASICs, independently. Power diode from each power the management board. In theory, one PCIe connector is enough to run SP20 at 1/4 speed.
Make sure the PSU PCIe connectors can handle 300 Watt.

So if you put an ohm meter across the 12V of one PCI-E and the ground of another, you're saying there won't be any signal back? They're absolutely independent? How were you proposing to put a third PCI-E port on the boards?

Does anyone know if the 4 power inputs on the SP20 are independent? ie: can I use multiple separate PSUs w/o causing a problem? I looked on the product page but didn't see anything in the specs either way.

Guy (Spondoolies-tech) already posted about it:

you can use 2X600W PSU
or 4X300W PSU according to him (perhaps he was joking about the latter one) with the only caveat that PCIE connector has to be rated for ~300W (ATX)-this is actually in bold red in TOS for Sp-20. This information is typically not readily available, but can be had from manufacturers on request.
Seasonic X-1050 and EVGA 1300 have this type of connectors. First-according to Guy, second-according to the post on the KNC forum that I cited beforehand.

You can use 2x PSUs but NOT 4x. Each pair of PCI-E connectors is electrically separate across 12V, but within the pair its not.

I think you are confusing the AntMiner S3 with the SP-20 I asked Spondoolies directly and they said, "Yes, the power connectors are independent. You can use 4 small PSUs, assuming the PCIe connector can handle 300 Watt"

While I wait for tech support to get back online, has anyone had a SP10 just not want to start up?

The symptoms are that it will not stay powered on. It will not even get to the point where is pulls a DHCP address so that we can access it. It will initially power up but then it will turn itself back off. I have no ethernet or fans. We tried different power cables and power ports on the pdu.

Does it sound like a bad PSU or a MMC corruption?

Is is correct to assume that this PSU is providing 1252W DC while using 1392W from the wall?

Thanks in advance.

As per my understanding .. the ASICS page is showing the current flow from the PSUs to every ASIC

The power supplies take in my case 1440/1472 from the wall, giving out 1292 to ASIC BOARD 0 and 1324 to the ASIC BOARD 1, respectively.

Quote from: 'cat /tmp/asics | grep PSU'

PSU-TOP[EMERSON1200]: 1440->1292w[1288 1292 1288] (lim=1295) 0c cooling:0/0x0
PSU-TOP[EMERSON1200]: 1472->1324w[1324 1320 1320] (lim=1325) 0c cooling:0/0x0

Zvi said it's a typo here, one PSU should read PSU-BOT. Then the power is split to every ASIC via the DC2DC ics ..

i.e. 12: DC2DC/1/:[vlt1:693 vlt2:695(DCl:794 Tl:794 Ul:749) 74W 106A 91c] ASIC:[ 85c 855hz(BL: 855) 439 (E:193) F:0]

means that ASIC 12 working at 855Hz is fed through it's own DC2DC with 74W having individual measured voltages .693/.695 and current 106A.

Your total hashrate seems low for 208V and ~30 deg C ambient temp. Going with higher deg C at intake keeping all other configuration constant, increases the asic working temperature and the unit compensates by lowering the current (asic frequency, hence the lower hashrate) to maintain the asic temp at about 85c to 105c. Zvi color coded the asic frequency using CSS for a bigger visual impact. And BTW .. an asic working at 105 celsius degrees is usually military grade / class.

SP30 newbie here with a few questions.

1] I have a few SP30's running on 208V. My hashrates after 12 hours range from 4.27 to 4.38 TH/s. My intake temperatures range from 29C to 39C. Is this hashrate range as-expected for a 208V source and those intake temperatures?

2] My units came with 3 different firmware flavors: 2.3.16-Rushbi3, 2.3.20 and 2.3.26. What advantages, if any, are there in upgrading to 2.3.43? I am of the "don't fix what is not broken" camp, so unless there is some tangible advantage (such as increased hashrate, lower power draw, improved power supply learning algorithm, ...) I'll leave them be.

3] if a unit is 'bricked' by a firmware update, what is the procedure to restore it to working state?

4] I have the 'fan speed' and 'maximum voltage' set at their factory defaults of 80 and 0.75 respectively. Has anyone played around with these values that can report their findings?

5] on the ASIC-Stats page there are PSU lines such as this:

Code:

PSU-TOP[EMERSON1200]: 1392->1252w[1248 1244 1252] (lim=1250) 0c cooling:0/0x6000

Is is correct to assume that this PSU is providing 1252W DC while using 1392W from the wall?

Thanks in advance.

From my short experience (less than 10 days)
1. My unit is at 208V and is able to reach 4500Gh or close by (4450 Gh). Unit's speed seem to improve after 24 hr (I guess it 'learns').
5. 1392 seems to be a lot, it will probably learn to be at 1350-1360 after a few shutdowns/restarts.

additional: if there is no secondary pool indicated, unit will shutdown on a loss of connection to the primary pool.

In general, to win in 2015 you'll need in descending order of importance:
1) Team or access to team with years of circuit design experience in advance nodes.
2) Access to cheap electricity - sub 0.03 $/KWh or less
3) Cheap production

or a nice SHA-256 exploit

Always helpful, assuming you don't abuse too much

1. Did you miss the announcement of avalons 28nm? (The 3rd chinese company to successfully make a 28nm chip)
2. Are you sure absolutely nobody in china can get electricity below $0.03/kwh? Is there a reason the farms need to be built in china?

1. No. I've been expecting it for a month now. It's a bit difficult to "argue" with you when you don't understand what I've meant by "circuit design" and gives standard cell design as a counter example.

2. Yes. I did my homework.

Can you confirm that the PSU-TOP/PSU-BOT typo in the ASICS tab is fixed with the upgrade?
