What is the temperature of SP10 chips and what temperatures do you estimate to have for SP30 chips?

In both cases the max Tj=125c. we design both system to allow the die working temperature to be up to 125c
To reduce leakage, we keep the temperature by sw control below 119

In the picture that you posted regarding the PSU there are no technical specs. There are only Environmental Specifications. Nothing about Ampers and Watts. You are the first company in the bitcoin mining field that draws more power than the PSU can handle. I just don't understand it and while on SP30 the overhead is low, in the SP10 the overhead is 30% which i find it pretty big.

The official DS1050 rated power is 1050W but the actual value the PSU was designed is 1200w.
After consulting with Emerson, to achieve max performance, we wallow to draw almost 1250w form the PSU.
We tested it and the systems in our lab runs under those conditions.
The PSU have built-in over current and overheat shutdown mechanism that protect itself and the system.

You can find the spec here: http://www.emersonnetworkpower.com/documents/en-us/products/embeddedpower/documents/documentationarchive/technicaldocumentation/01/trn_ac-dc_ds1050-3_release1_0_1312516765_techref.pdf

Sounds like ...NO running engineering sample for SP30...right...?

Correct.
We're deep into the design cycle of RockerBox, the ASIC inside SP30 Yukon. By running simulations, we know it's parameters and we're able to design and simulate the miner.
In SP10, we've aimed for 1.3 TH/s with margins and we got 1.4 - 1.6 TH/s. SP30 parameters will be according to the spec we've published.

When do you plan to tape-out the RockerBox?

I see that you are avoiding the temperatures questions. Will try again. What is the temperature of the Hammer ASIC chip while running? What is your estimation on the temperature of the RockerBox?

Thank you for this clarification...

On the other hand you are taking pre-orders for that "deep design cycle"...based on simulations...Just trying to get the "whole picture"... Wink

Clearly Meni has never seen the hardware. Where is Adam's review of the hardware?
My point still stands. Why were you so desperate to open orders before delivering any actual sample hardware?

Meni will get his evaluation unit tonight. Adam will get his evaluation unit next week.
Desperate ? Definitely not. We are proud of our product. We opened orders the moment the web site was ready.
We didn't ship until yesterday because we preferred to do the necessary burn-in testings. In addition the UI wasn't ready.

Please see the thread, several respected members of the community (Adam Back, Meni Rosenfeld) have visited us in person and seen the units, before providing their confirmations.

Small correction, Meni didn't visit us in person yet.
We're giving Meni an evaluation unit tonight (Israel time).
Adam Back did visit us a month ago.

"This message" being that I consult for Spondoolies-tech and have known some of the people involved for about a year. I haven't seen the hardware yet, but hopefully that will be soon.

I really wanted to order one SP10 unit, but i couldn't find enough information about the PSU. I don't want a fire hazard and i don't know how long will the PSU last before going dead.

Sorry, missed this one.

The PSU we are using was designed for the telecom and communication market by Emerson, one of the most respectable PSU providers in the world. It meets all the required safety certifications and it's MTBF (mean time between failures) is over 50 years.
In addition it supports over-current shutdown and over-heating shutdown, hence there is no fire or any other hazard risks.

SyRenity please address the issue of SP30 heat dissipation. How do you plan to dissipate 2500W from that small case? Also i see that you under power it again. For SP10 you have a 1kW PSU and the unit needs 1.3kW and for SP30 you have 2 1200W PSUs, but the unit needs 2500W.

Also what is the inside temperature that SP10 reaches? (chips, components etc)

Answer from the team:

Quote

When designing a cooling solution, the most important factor is the heat density, rather then the performance or the total amount of the dissipated heat. The second factor would be the max allowed ASIC’s Tj.

You are right, we are going to maintain the same air flow cooling mechanism for the SP30 as well. We going to use a custom heat sink that was designed and manufactured according to ASIC’s heat dense and Tj with 80mm Fans with a total of ~300 CFM.

The heat sink will be composed of Aluminum K=167 W/m*K 6061 T6 and copper base attached to the ASICs themselves.
The entire design is backed up with a thermal analysis simulations that we are performing as part of the mechanical and electrical design process

What is the temperature of SP10 chips and what temperatures do you estimate to have for SP30 chips?

You should have done that before accepting pre-orders. It looks like a desperate money grab when you take pre-orders before any community member has seen the hardware.

Please see the thread, several respected members of the community (Adam Back, Meni Rosenfeld) have visited us in person and seen the units, before providing their confirmations.

That said, the first unit will arrive to dogie soon, who will provide a professional review for the community.

We have shipped the units for review, we hope the reviewers enjoy mining with them as much as we have enjoyed making them.

SyRenity, it all looks legit... like I said, if turns out to be a scam, someone will make movie about you guys :-)

However let me ask you few questions that yourself have asked in the past in other threads...

1) Are you guys willing to lower the declared value for VAT purposes?

2) Are you guys willing to lower the price for batch #2 if not for batch #3? May onwards ROI is horrible (-1 BTC) if BTC stayed around $600 and difficulty increases 15% per increment but we know it will be higher that with Bitmain and you guys releasing your machines in April onwards...

3) Are you guys pre-mining with the machines at the moment in your datacenter?

Fair enough

:

1) Unfortunately not at the moment, though we are looking at the available options for the VAT markets.

2) We will need to get back to you on this one.

3) We do not do any self-mining with our clients units (beside standard limited burn-in tests) - this is one of our company principles.
