Hello All,

How did the SP upgrade to 2.3.43 went?
Did anyone have had to manual power cycle the machines?

thx

Hello All,

thx

Mine went seamlessly, and then to 2.3.46 as well. Haven't seen it make any difference though

[jimmothy]

I wouldn't be betting against what Guy is putting out here. There is certainly a deepening divide in the quality and if you are required to go develop or find a

1) Team or access to team with years of circuit design experience in advance nodes.

Who has that team or access to that team?

BFL? Pfft
Bitmain?
Bitfury?
KnC?
Avalon? Really you'd trust them given their last few offerings chip wise. Nope.

Who is left that is actually not struggling with current tech?

How am I (or Guy) supposed to know without knowing every member of every team and each of their experience in advanced nodes?

Is Israel the only country with people who have experience in advanced nodes?

Not sure what you mean by struggling. Is bitmain selling out batch after batch of S3's considered struggling?

You seem to ignore the actual product that SPTech has shipped is exceptionally well engineered. Go ask the competition about it. Some of the people I have talked with WISH they had the team SPTech has.

It's a nice product and efficient chip (even though they advertised much better) but I'm not going to share my magic crystal ball readings about their future potential.

I'm just wondering why a company who has hardware development problems of their own is suggesting all companies from China will all of the sudden stop being competitive. All evidence would suggest the contrary.

[Guy Corem]

These competition points raised by Sptech could be valid, but i think he forgot about a major factor that may undermine the whole industrials at this point: btc price..
Whatever cheap electricity or manufacturing costs you could get, peofitability will be driven by btc price obviously. And with it stabilisîng or tanking even more, some rushers might get squeezed and go bankrupt.
Interesting times ahead.

Under current BTC value, the bounty is $1.2BN until the next block incentive halve.
For sake of argument (only ), let's assume you're able to develop 0.2 $/GHs or 0.1 $/GHs (or below ) hardware.
How does the math look like ?

[Guy Corem]

Is Israel the only country with people who have experience in advanced nodes?

Definitely not.

[Guy Corem]

Where did I say that?
You've missed the point that I was talking about 2015.
The nature of the business is that it resest itself with each generation.

[Guy Corem]

The russian self taught asic designer?

Valery (both of them) won't appreciate being called Russian.
But yes, BitFury is #1 on my list.
They have enough $ to hire top world talent.
They have proven execution track record.

[wh00per]

Anyone with a SP30 on the latest firmware?
Can you confirm that the PSU-TOP/PSU-BOT typo in the ASICS tab is fixed with the upgrade?

Cheers!

[Guy Corem]

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.

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

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.

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.

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.

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?

[dogie]

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"

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.

[Biodom]

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?

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?
