I tried assigning a reservation at the router for my sp10 ip address but when it resets it still gets a new ip address for the sp10.  Is there a reason the saved button doesn't work on the UI.  Thanks. 

Please email support@

All in stock SP10 were ordered.
Next production run is mid June.

If there will be cancellation or non paying, we'll open "immediate delivery" stock.
Congratulations on your success!  I'm very satisfied with my SP-10, and am looking forward to great new innovations from you in the future (SP-15, SP-30, and perhaps the next-generation SP-50 - a 10TH/s beast on 20nm chips with the same power draw as the SP-30)

EDIT: The SP-50 is a fictitious product that I have made up (but hope sees the light of day) and in no way represents Spondoolies-Tech product pipeline Smiley

Thank you for your kind words. PickAxe is also 28 nm
Your spec is way off. Please refrain from future speculation about the it's spec. The SP50 will arrived in late Q4 or early Q1
We won't take pre-orders since it's an high risk product. A completely redesign engine.

... Now that I recall that you use large shared heat-sinks ...

In the SP30 we use heat sink per ASIC. Due to mechanical stress issues, we preferred not to use large shared heat-sinks on top of the FCBGA ASICs



Nice picture. Does the flat bottom of the SP30 get as hot as the SP10 flat bottom does?




No

The only heat sinks are on top of the ASICs, per the SolidWorks image.
The design was done with the same thermal analysis experts that did the SP10
Thank you for that information.

Could you confirm that the maximum airflow of the sp30 is around 2.3 times that of the sp10?

This is the number i came up with when crunching the numbers with those new, higher cfm 80mm fans.

Is it safe to say that the combined surface area of the sp30´s heatsinks is around the same as 2 sp10s?

By the way, PCBs look nice.

Will ask the technical guys. Here is some info I have when contacting data centers for quote:

SP10: ΔT=18°C and 110 CFM @ 80% Fans utilization (“Turbo” mode)
SP30: ΔT=25°C and 210 CFM @ 70% Fans utilization (“Turbo” mode)

Does this mean there will be additional heatsinks on top of the chips aswell as under the board or only on top of the chips?

If the second option, will you be looking at higher thermal conductivity ie. copper heatsinks to compensate for the lower surface area or will you be making the heatsinks with a higher surface area?

It seems that work in the spondoolies DC is still ongoing and just took some units of mine offline, but i know they will compensate for lost time so no worries there.

Correct. We'll compensate.

Who cares what rev it is? Do you really think spondoolies went through no revisions?

My friend and favorite AM SH is back. I hope the dividends were substantials Wink
Of course we had revisions.

The answer is no to both questions.
So can you tell us what is the motivation for the unusual design approach:

1) easier to simulate the mini-circuit
2) RF design to minimize reflection and noise in the traces
3) pick&place machine speed optimization or other manufacturability concerns
4) all of the above

The contrast to something like Enterpoint's quad FPGA board is obvious.


My guess is power rails. Each ASIC consumes about 80 Watt
Will ask Harel or Benny


Harel reply:

The Idea was to have the ASIC and it's DC/DC as close as possible.
This block was layout together as one piece. Once the block's layout was done it was duplicated 15 times per each main board.
The location of the ASIC was set based on thermal simulation results that took into account the Heat-sink dimension and the box's air flow.

btw: for ASICs customers, we're giving the entire SP30 production files as a reference design.

SP30 management and main ("ASIC") boards:
...snipped...
I have to ask: the main boards look mechanically designed to be cut/punched into 15 separate mini-boards. Are they indeed designed like so electrically?

Or maybe answering the above question will violate some of your non-disclosures?



The answer is no to both questions.

Any other bundles or discounts for SP-10 / SP-30 planned? I noticed the original post here hasn't been updated in a long time and has old sales.

Contact sales@ for bulk discount

Hi to all,

bitguy.com cloud hashing - good service guys or scam?

Can anyone thinks?
Who use?

I confirm that we've sold a lot of SP10s to BitGuy.com owner.

Hosting for SP10 was added back

Thanks! Typical that BTC has a 10% selloff as I about to pull the trigger. Need to wait until we recover.

Pull faster (or don't attempt to draw, so it will go higher Wink)

I have a late May unit, and it's only averaging ~1300 GH/s at the pool (BtcGuild) using the "turbo fans, highest rate" setting. Is there anything I can do to increase performance?

This unit is running in a data center using 208v power, and temperatures are good (27C front, 69C back). I was expecting a bit more, so hopefully there are tweaks I can make to increase performance and this isn't just a low performing unit.

I have the same thing on 2 units.

This is why the +- 10% is for. There will always be some manufacturing differences.
If you're unhappy with your miner performance, please contact sales@ and we'll work something out.

I was wondering that too for the same reason, had 2 in my basket last night, went to pay this morning and wouldn't let me Sad

Hosting was added back.

Awesome, thanks Guy another 2 bought Smiley

PS Did you spot my follow up email last night about the error in one of my worker names . instead of _

Thank you.
Yes, it will take us some time to fix

We've temporarily stopped accepting new hosting requests, until we'll finish out data center enhancements and expanding work.

Any timeframe for hosting to be available again? The tax/duty on imports kills this for me.
