Chances are the tubes will not work though...the fail rate is amazing.  I agree SP is expensive, but at least it works. AM does 0 quality control.

Wasn't it actually your Ethernet controller which failed? You know, that cheap, separate component you were told by FC to buy a couple of because they were known to be shit? That component you only bought 1 of for some reason despite being warned about their failure rates? That component you can just easily swap for a new one? That component which isn't even actually necessary to mine with?

Didn't you sell the Tube anyway?

Those percentages relate to the luck of the pool during the time it was mining.

You can't compare the SP30 stats and the S3 stats unless they STARTED mining at the EXACT same time and have both been mining for 100% of the time.

If you check several users in the contributors list you will see everyone has different percentages, if you don't believe me ask in the eligius pool thread.
https://bitcointalk.org/index.php?topic=441465.0

I guess the awarded shares have to move closer to 100% over the longer term, correct?

I think the long term average on eligius is around 98% (mine is 96% but I don't mine there all the time), it'll never get to 100 due to orphans, but it will certainly rise though 2x 8.5 hour blocks today won't help, just bad timing starting during a bad luck period Sad

Take a look around...tons of bad boards, controllers, and dead chips.  Yes I ditched it ASAP after seeing feed back on them plus dead controller.  Fact is they are poorly made and no QC.

Sorry SP I will not litter your thread any more.

Any actual numbers about the P2Pool performance of these devices?  Is anyone out there willing to mine on my 0% fee p2pool node for a while so I can see what one could expect out of one of these devices?  If so, please PM me.

Hey Og, both the SP10 and SP3X have been confirmed to mine within specs on p2pool.

I must admit that the hashrate and the DOA varies a bit. I will return on Sunday and I will update one more time.

That explains some things.

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.

Because it's a major discussion in the S3 Thread:

Is Spondoolies-Tech using the latest version of cgminer (v4.6.0) in all their products?

I have respect to AM and Bitmain past achievements, but they're not high on my list. I don't believe China will be able to compete in 2015

Can you elaborate as to why?
I'm under NDA with various parties, so I can't give concrete information.

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

From what I was able to learn, the Chinese teams (including some publically unknown) has only (3) above.
Some of them are rushing to bleeding edge nodes (TSMC 16 or Samsung/GF 14) but it's not enough.

Spondoolies is the ONLY company remaining that is in sync with the mainline cgminer code and always push upstream any driver changes.

That alone should be THE reason to prefer SP over Antminer!

To be fair, bitmain are a close second, putting their code up when requested, but it's a fork and not really mergeable with the mainline cgminer code as is; they expect us to make it mergeable but then when Kano did that with the S1 code they never bothered to get back in sync with the mainline code. This ends up being worse for both parties but there is cooperation unlike with a lot of companies.

Spondoolies on the other hand are following and staying in sync with the mainline cgminer code which is the reference for how it should be done and they should be lauded for it. Other companies have done this in the past and after a while given up and done whatever they wanted and ignored us even though their hardware is absolutely dependent on our software - in the end they have missed out on guidance from the very people who wrote the software, and features and bugfixes in newer cgminer versions.

number 2 is pretty irrelevant for miner manufacturing.  Question regarding number 1.  How strong is IP protection since you still have to get the chips made over there anyways?

My reply is regarding 2015, which will be all about mega industrial farms or franchise / JV type deployments.
Access to multi MW low cost electricity will be the limiting factor. China lacks cheap electricity and free MWs.

No issue with IP protection, manufacturing is done at Taiwan (TSMC) at least for us.

Always. It depends on our relative advantage.
In 2015, it might be in a form of a mining facility "bond".
