Aaarghh... anybody noticed the rise of the hash rate during the last 24 hours. This is really frightening. Spondoolies: Could you please make sure that September starts tomorrow :-)

Looks like someone was waiting for the difficulty change before turning on a few PH

Where do people get this ridiculous notion from?

No one in their right mind is waiting for a difficulty change before turning on a massive amount of expensive mining equipment. Everyone knows you can't make money if your machines aren't running.

And no one entity (or multiple entities, for that matter) can just instantly turn on enough hashing power to influence the difficulty by any significant margin these days. It takes weeks of setup and testing to deploy multiple PH farms. No doubt they are switching units on one at a time until fully deployed.

Thanks Collider, already done ... I await a response from them.

EDIT: In true Spondoolies fashion, I have received a quick reply from Guy who has confirmed they will replace the PSU and send it directly to the DC. They even want the burnt out one back so they can analyse it.

Thank you again Spondoolies for an excellent service, I have nothing but praise for the timely support I have received today, and in the past.

Does the DC charge you to swap PSUs?

One of my SP10s which is hosted in Iceland is unfortunately down, as the PSU has burnt out. It went down a couple of days ago, at first I could still access the miner, but couldn't get it to start mining again. Remo from Spondoolies kindly had a look for me and confirmed the voltages weren't right which is why it wouldn't mine. After a couple of hard resets, things were no better.

The last reset was a reset too far, and the tech emailed me saying: "There is definitely something wrong with the power supply i think it has burned out. I unpluged the server and plugged it back in and then a strange smell and a little smoke from the server, so i have unplugged it for now".

They even emailed me a picture which I thought was quite good of them.

Anyway ... has anybody else had a PSU go down? I'm not sure how to proceed, but await to see what advice Spondoolies give.

I would expect this problemto appear more frequently with the sp30 what do you expect running psu at 110% capacity?

send then email, they will send you a new psu + give you hashrate while your unit is down

wow, this is excellent, i hope that it will continue into the fall...have doubts about the robustness of PSU "learning" procedure because of high temp variability in most hosting sites.

I can tell you that my Sp30 doesn´t show the initial (very short) resets anymore, so the learning seems to work quite well.

It is basically only discovering the highest thermal stress the PSU can take at the current settings, and limits itself to the maximum stable current.

You might therefore be able to achieve a small increase in performance in a cold hosting environment, but the overall impact of temperature on hashrate should be even lower than on the sp10s.

If within 3 months from buying they will send you a new PSU for free (to the DC).

I was hoping this would be the case, Spondoolies shipped my orders on 13th May so all should be OK.

Just make sure you actually send them an email (and get an automated message back that your ticket was received), ideally with your order number and "PSU failure" in the subject of your email.

You can also upload the picture of the burnt-out PSU and link to it in your email, it should accelerate the process.

Alternatively, you could buy a used PSU for around 40$, but please check with spondoolies before doing that, as I am not sure whether it would void your remaining warranty.

Is there any P2Pool near the US and or Spondoolies own DC?
It would be awesome if Spondoolies setup an own P2Pool inhouse with very low latency for the hosted miners!

We will be hosting a p2pool node soon. It should be up in about two weeks, I'd guess. Our latency to Titan, the DC that Spondoolies uses in central Washington, will probably be about 5 ms.

Of course, if you hosted with us too, then your latency would be under 1 ms, and you'd pay less money on hosting fees.

using a gas with higher thermal conductivity than air?

It's true that moving the heat from the ASIC to the air is an interesting problem, and the current heatsink and gas combination will struggle to transfer heat to air in that much space at that power rate with that small of a temperature difference between the ASIC and the air. However, doing things the traditional way is boring. I'll just leave this here for you guys.

Thermal resistance is about 0.2°C/W, about 1/4 of a typical heatsink+fan setup.

Hi There,

I'm new to Bitcoin mining. I ordered a unit from China but it came with many faults to i'm returning it and looking to get the new SP30. I have a few questions which I e-mailed directly to the company but received no reply. Would anyone help me with the following questions.

- If I ordered the item next week would you still ship the item to me in September?
- Do you accept bank wire payment from London
- How is the on-going support if there are any damages while shipping the item to London
I'm asking this because I had a miner shipped from China which came damaged and then could not refund the item.
- Can I plug the miner into the normal UK power supply? 240v? Or will I need a step down transformer?
- Does the item come with warranty?
- What is the cost of the duty when the item arrives in London?
- How long will it take for the SP30 to come to London?
- If there are any faults after delivered will you take the item back under your own shipping costs and repair the item and send it back all inclusive?
- Finally when I go into the payment section it's asking whether I want hosting too? What is this hosting for?

Sorry for the overload of questions. I just want to be clear before jumping into this investment.

Thanks,
Charles

I think its too risky to order the Sept batch right now because you would not get your units till near Oct
Only a few Aug batch units have shipped and its a quarter of a way through the Month which means Aug batch won't be shipped till almost Sept imo. Diff seems to be going up already so Sept batch could be very risky

Part of it could be statistical variance.

We can wait until 2-3 days before the next change and discuss this, as anything right now would be pure speculation.

Yes, that would be awesome and I suggested it to Zvi.

He apparrently didn´t have enough time to do a quick setup of a p2pool server or did not want to do it.

I would also not recommend you hosting your sp30 at spondoolies own DC for an extended time, as it is quite pricy (as power in Israel isn´t cheap).
