Why is the SP20 less efficient than the SP35?

I thought they used the same ASICs?

SP20 1100W / 1700 GH/s = 0.65J/GH
SP35 3500W / 6000 GH/s = 0.58J/GH
Indeed same ASICs.
The SP20 should give better results then what we published. We'll get the faster ASICs in 2 weeks and revise the spec.
Also, iit depends on the PSU efficiency.

Thanks! Keen to hear revised specs as soon as they are available. Sounds like SP20 efficiency is understated at the moment.

Good luck finding quiet 100 CFM 80mm fans.


Thanks for the info on CFM.

What is the db of the existing?

here are some 80 mm at 100 CFM or higher ..

While poking around I noted some talked about just putting in more fans, with out knowing the layout of the inside, sounds possible ...

However mute it might be after this year on this unit anyway ...

Well, I have to admit that I'm currently waiting for the S4 specs and price be revealed. Although there is no valid point in investing in mining now with difficulty going through the roof (network hash rate has already spiked to above 260 PH/s, currently sitting at 250.5 PH/s) and BTC price in the cellar, I'm prepared to purchase my very first mining gear, because winter is coming and my plan is to let the miners assist in heating the house.

SP-T has really something going here, but unfortunately the long delivery times, high price and especially the high shipping costs speak against the purchase of a SP20 or SP35. Considering the total purchase price Bitmaintech offers a better $/GH rate, and although SP-T had a better W/GH rate so far, it may be beaten by a S4 with underclocked/undervolted ASICS.

$/GH and W/GH both have to be right, which is why those Tubes with W/GH way off can not even be considered.

I'm not giving up on SP-T, but something has to happen, because it's just not working that way. We need some innovation to bring W/GH below 0.5 and price + delivery times down, which may be impossible right now, but I have hopes for 2015.

Let's assume a static network hash rate of 300 Ph/s, power costs of 0.1 USD/kWh and an exchange price of 500 USD/BTC.

SP20 costs 2.64 USD/day,
SP35 costs 8.4 USD/day,
S3+ B9 costs 0.86 USD/day, and
AM Tube costs 2.16 USD/day.

SP20 at 1700 Gh/s would mine 0.0204 BTC/day or 10.2 USD/day,
SP35 at 6000 Gh/s would mine 0.072 BTC/day or 36 USD/day,
S3+ B9 at 453 Gh/s would mine 0.005436 BTC/day or 2.72 USD/day, and
AM Tube at 800 Gh/s would mine 0.0096 BTC/day or 4.8 USD/day.

SP20 would make 7.56 USD/day profit,
SP35 would make 27.6 USD/day profit,
S3+ B9 would make 1.858 USD/day profit, and
AM Tube would make 2.64 USD/day profit.

SP20 costs 1,500 USD inc. PSU + shipping, it would take 199 days to break even,
SP35 costs 4,035 USD inc. PSU + shipping, it would take 147 days to break even,
S3+ B9 costs 320 USD inc. PSU + shipping, it would take 173 days to break even, and
AM Tube costs 500 USD inc. PSU + shipping, it would take 190 days to break even.

The network isn't static though and AM Tubes are the only miners in stock. I'll leave you to draw your own conclusions.

When will you state your AM affiliation in your signature? It is fair for everyone to know, just like they see in my signature my affiliation to SP-Tech.

When I participate in the signature campaign and get paid to do so. Will that change the maths though?

But you also get paid in form of dividends to advertise AM products so I think it's fair for everyone to know that you are an AM shareholder. I am not getting a direct pay for having an affiliate link in my signature. I only get paid if/when someone purchases a product using my affiliated link. Otherwise I don't get paid, while you get paid for anyone purchasing any AM product.

You can consider this off topic, but I think I must say this.
After working with almost any available for third parity developers ASIC chips for the last year We can state that the RockerBox is state of the art in terms of delivering the advertised parameters , communication  and flexibility.
Also the Spondoolies team could not be more responsive in order to assist us during the development .

Nice to see some twerking of the heatsink going on there SPTech loved to see the results of those tests.

Thank you. RockerBox will improve with each batch starting from October, as we continue to tweak the production parameters.

bla bla bla ...
Due to the diligent work of AM minions, our little thread is now #3 in replies rank.
Thank you.
As I wrote before, FC in person is a great guy. BitQuan seems like a capable company. I like them. Can't say the same about some of their SHs

I wasn't advertising any miners either when I was raising legitimate questions/issue about AM sales and self mining, yet you and the other angry AM shareholders were stating that I am just trying to promote SP-Tech products even if I never mentioned any product name in my raised issues.

Math isn't lying, but sales are a good proof that even with your math the products(Tubes) aren't selling.

I have to agree with this, Spondoolies has by far been the best company out there to work with.  Even with my impatience they have been great.


Keep up the great work Spondoolies.

Once again it has to be pointed out to you that you don't know the difference between fact and fiction. You have no evidence whatsoever to claim that Tubes are not selling. If they wasn't selling, how could they be on batch 3? This is the type of shitty trolling you keep doing on AM threads, spouting off about how crappy AM is doing and how great Spondoolies are while just happening to have an Spondoolies link in your sig. In other words, you are spreading bullshit about your competition in their threads while simultaneously promoting Spondoolies.

Guy, this is the main reason AM shareholders don't like Spondoolies, you have a pathological liar acting as your PR who keeps trolling the AM thread. RoadStress does not know the difference between a fact and an opinion and keeps trying to pass off bullshit as facts. If you keep paying him to do this shit, then don't be surprised if this thread gets filled with AM banners. RoadStress is a liability to your company and if you didn't agree with the shit he's doing you would cut him loose for being such an embarrassment.

I got the information directly from FC:
1. Due to the relatively lower interest from individual miners as well as OEM producers, the self mining has re-started from middle of July.

Also do you know how many units were sold in each batch? Being on batch 3 means nothing in terms of numbers. When you will have some sold units numbers then please come back again and let us know. For example SP-Tech sold 1k SP30 units in August. Have the Tubes passed the 1k units in those 3 batches? We/You don't know so stop assuming things if I'm not allowed to do it.

Edit: Also the lack of activity in the AM Tube thread shows how unpopular are these miners. Let's compare:
- AM Tube thread has 472 replies and it's 1 month and 1 week old;
- S4 thread has 144 replies in just 2 days

This is the type of shitty trolling you keep doing on AM threads, spouting off about how crappy AM is doing and how great Spondoolies are while just happening to have an Spondoolies link in your sig. In other words, you are spreading bullshit about your competition in their threads while simultaneously promoting Spondoolies.

Please show me where I said how crappy AM is doing AND IN THE SAME TIME how great SP-Tech is doing.

I have tried numerous times to have a normal talk about AM plans, but nobody wanted to reply to me with solid arguments. Do you remember this thread https://bitcointalk.org/index.php?topic=715480.0 ? I invite you there to explain to me how will AM self-deploy ~30PH/s.[/quote]

Guy, this is the main reason AM shareholders don't like Spondoolies, you have a pathological liar acting as your PR who keeps trolling the AM thread. RoadStress does not know the difference between a fact and an opinion and keeps trying to pass off bullshit as facts. If you keep paying him to do this shit, then don't be surprised if this thread gets filled with AM banners. RoadStress is a liability to your company and if you didn't agree with the shit he's doing you would cut him loose for being such an embarrassment.

They are not paying me to troll your thread don't worry. I do it for personal pleasure just like I did with scammer Ken Slaughter. I notice a ship full of blind shareholders going down and I try to present my legitimate issues to them. Instead of being rational they keep telling me that I'm trolling them. I'm fine with that, but that will not stop me.

As for the pathological liar...ok. Please show me proofs of lies, but please do not repeat the same mistake as jimmothy who presented as lies some future predictions, instead of facts.

From initial testings with the slow ASICs we currently have, we see great over clocking potential in the SP20.
The limiting factor is cooling, and we're working to improve it. Experimenting with various enhancements to the heatsinks.

Convinced me to use my coupons and giftcard to pull the trigger on an sp20, finall cost was $364.94

not too shabby for 1.6TH i guess.   Hope it delivers quicker than the sp30 did.
