Can't wait to test the low Iceland temperatures 

Ooh, source code?  This sounds like it could be even more fun than I thought.


... I'm aware of that, thank you. I'm also aware that publishing my intent on a thread watched by several Spondoolies employees means that I can't play dumb later when things go wrong.

I think what I'll do for now is just buy one Emerson and use it to test out some mods in a fashion that only risks a $35 ebay device, and doesn't require me to take my SP30 offline while I play. If it seems like the case mods should work, I'll either recompile the source, swap the PSUs guts (along with its I2C ID), or if I'm feeling cocky, just perform the mod on all of my Emerson PSUs.

The SP30s will restart a lot for the first 24 hours or so after you plug in the PSUs. The purpose of this is to test the limits of what the PSUs can handle before they go into thermal shutdown. The SP30 brings the PSUs up to the limit of their performance, then over, and remembers the power level at which it exceeded its tolerances. During the next boot, it uses slightly more conservative settings until it never exceeds those tolerances. Personally, I think this is a pretty cool feature (although a little bit crazy). The SP30 basically overclocks itself automatically.

Disconnecting the PSU's power will reset the SP30s knowledge of the PSU's limit, and will cause this algorithm to start again. If you change the cooling conditions for your SP30, you should power cycle your PSUs so the SP30 learns its new limits.

Edit: See zvisha's reply a few posts down for the correct way to reset the PSU's limit-finding algorithm.

Don't buy emerson on ebay unless you want to recompile the source code to recognise it. We have special I2C id.

once you made a bigger hole, it is usually cannot be undone easily (without replacing the whole net/panel).
could void the warranty

My first SP30 arrived on Friday. It was part of the April/July Better Together batch. I placed the order on March 21, 2014.

That sounds about right. The air coming out of the PSUs was about 15°C hotter than the air coming out of the main fans, and the PSU fans run at a much higher RPM. Maybe today I'll record an audio sample and run it through a Fourier transform.

I bet SP30 performance could probably be improved with some aftermarket modifications to the PSUs for airflow. I see the Emersons are available on ebay for reasonable prices, but I can't find the Murata PSUs there. Perhaps I'll buy a couple extra Emersons and see if I can mod them for better airflow. For example, the hole that the fan exhausts out of seems to be quite small. I'd guess that expanding those holes a bit would likely improve airflow, thereby reducing temperatures and expanding the load headroom before thermal shutdown. It also might be possible to mount a fan external to the SP30 case in push configuration in front of the PSUs. In my DC, we're already planning on setting up a sealed tunnel hot aisle config with fans forcing extra air through the SP30s. Perhaps we could set up baffles to encourage a higher proportion of the extra air to flow through the PSU. I'm looking forward to playing around with this. I think the hole widening would probably result in the biggest improvement.

Obviously, Spondoolies cannot condone or support such behavior, I know.

I have not deleted any of my posts and I will not do it. I do take responsibility for what I have said in the past. Can't say the same thing about you since you would delete your posts.

As for the shipping queue if you are not a customer SP-Tech isn't obligated to present you the shipping report daily, same for the compensation package too. There are only a handful in the wild because there were just a few July orders and my July order was shipped in July and until now nobody complained about any delays. August orders will be shipped in August. Since it's just the 3rd day of the month I don't see how can there be tons of units in the wild. Since the compensation package will be offered in October for me as a customer finding the details now or in 2 weeks or in 4 weeks it's exactly the same since whatever I will receive will be in October.


My unit arrived today in Iceland. I hope to have it hashing online tomorrow if not then it will be online Tuesday for sure.

disappointing I guess.....that was a pretty huge miss the hashrate and the power use...but to be expected I guess...min compensation...more then that

too much to hope for.......now just need all this stuff to creep out a couple weeks late...to wrap it all up in a bow...

I read this that if you ordered when machine was considered 5.4TH, then your base is 5.4TH, same logic for those (like myself) who ordered when machine was advertized as 6Th. Power use is a point of some contention, allegedly. If you ordered when it was 5.4, then the deficit is ~17%, and 25% for 4.5vs 6.0Th. It is not clear what would be a fair procedure for power calc.

well looks to me it is just gonna be $$$/gh nothing for the worsening elec/wattage increase...

or am I reading the below wrong



so....we look to be compensated for the 6Th (or are they gonna use 5.4TH? as the BASE speed?) but not for the increased power usage....
or I missed another memo and am reading the above incorrectly?

Are sales people there at SPT? No reply from sales.

It is normal in the first day.
Let's see how it settles down. Should stop restarting.

Dunno … maybe RoadStress got an early one ? I remember him crowing a chapter or two back about expecting his first one with Collider.

It is only fair. What we have here is ST rushing out their small batch of early orders with what amounts to test samples from the foundry. Normally, these would be used for testing and adjustments would be made in the manufacturing process until the design target was reached. Then, and only then, production would start. ST chooses to ship em, they should compensate fairly.

The compensation will be for the missed GH/s, per the specific $/GH/s ratio of each customer order. It was explained numerous time before.
We'll allow each customer to select the form of compensation. More details soon.

Thats a very good question Edgar. Very good question.

I am not trolling anybody's threads Z. Several of us are active on the Alpha-T thread at the moment because Alpha-T is a disaster in full progress and I have been helping people like Vesperwillow, Retro72 and Aderl pull the curtain back on the Alpha-T operation so their customers can get a better view of the developing disaster and act to save their deposits before it is too late.

You won't find me trolling the Bitmain thread either. I have some Bitmain equipment and I think highly of Bitmain but whenever I mention  Bitmain in this thread it is only to point how what a bad deal the Sept. SP30 is compared to S3 because S3 is shipping now, its not a preorder. By now everybody realizes I hope that 10 S3 in the hand will mine 4-5 BTC before the Sept SP30 even starts mining and therefore the Sept. SP30 is overpriced.

I get it that you don't like that and would like to bury that message with accusations of trolling, but its just a fact.

On the 110 volt underperformance, I've followed this thread for a long time and never noticed any statements by anyone that the SP30 would have the same problem in this regard as the SP10. I was nearly a Farmer's Choice customers and I was nearly a RS GB customer (I got lucky and dodged those bullets) and rewiring my house was not in the budget, is not as cheap as running down to Home Depot and picking up a new box and some wire and in any case is not an option for me. There is no good reason why correctly designed equipment should perform worse at 110v than at 208-240v. Sure the efficiency may vary, but there is no reason the hash rate should. I consider it a design fault.

I am so glad I skipped on the SP30. And I am so surprised at the amount of pushback I am getting on what I consider to be very legitimate observations and questions.

And Z, if you want to take issue with trolling, ST have several well known trolls of their own whose behavior ranges from bad to infantile. Go read the KNC thread if you need to for examples.

Maybe it depends which part of europe but trust me I have put a voltmeter on the supply and it is 240v not 220v.

You can also get three phase with 415V which relates to sqrt(3)*240=415.

Adam

usually the US/CANADA is wired with a Hot 120V, neutral (0V return), and Ground (0V safety). Changing the neutral wire for a select outlet to run on the secondary phase of 120V will give you 240V at the outlet and work with a 'typical' PC power cord.

however, running 240V in a 120V socket is against code, so it should be switched out to a 240V-speced outlet.

ok what did I miss...er....OK I get it....because of the decrease from what 6TH to 4.5TH ....vs power use...DUH!

anyway what he said above (better minds then me)
