Does anyone know if it is possible to use 2 or 3 coupons on 1 order (1 single S2 miner)?

~ Luc

No, one coupon per miner in the order.

So if you have 3 coupons you have to have either three separate orders or one order with three items in it.

SP10's chip that is on 40nm is more power efficient than Jupiter's chip that is on 28nm by far. (0.85W/Gh vs 1.1-1.2W/Gh at system level) SP30 will be at 0.5W/GH at system level which is on par with your prediction which will turn out false. I feel that Neptune will be 0.7W/GH which is worse than SP30. So why pay the expensive 20nm mask if you can get the same performance from a 28nm chip? What's the advantage?

I think to be fair at system level a Jupiter is a lot less than 1.1-1.2W/Gh

My sole surviving one sits at 840Gh at 800W at system level and thats obviously overclocked.

OK so $1650, then if you have to ship to an EU country we have to add another 20% or more on top? Plus shipping from Switzerland?

Would it not be better to get it shipped direct from China to the final destination?
1925  Bitcoin / Group buys / Re: [GROUP BUY][CH + EU] SCRYPT & SHA256 Miner (Hosting & Versand) New Products! on: June 13, 2014, 12:15:16 PM
Can you explain more the VAT situation?

You get charged 8% VAT to import into Switzerland correct?

Does that mean your final price for pickup or hosting in Switzerland is:

e.g. 1500 A1 miner @ $1500 + 8% = $1620?

Can you indicate what the hosting costs would be for a single A1 miner? As from what I can ascertain hosting in CH isn't cheap.

Anyone got any news on how Payment to Hosting company works , what are the payment options. e.g (all up front or on a month by month basis).

Asked Spondoolies for this info two days ago, no answer.


The email said that hosting required a 6 month commitment, which would indicate to me that it required 6 months up front. What other commitment would there be for a company selling hosting to a bunch of geeks on the internet from all over the world?

Bad news.
Over one week ago Juan called me and stated the refund was issued that very same day.
8 days passed, no money, phone calls bounced to voicemail.
Our company's legal firm luckly operates in both UK (where the company reside) and US, on monday if the money are not there we're setting up a meeting with them.

I just got a refund today for 3BTC after chasing for 10 days, I know he's been pretty flat out. Just keep emailing.

Sorry for the delay I run out of BTC to complete the refund.

Now I just have to complete one last refund of late payment orders.



No problem Juan, as I said I'm happy with the result both of the group buy and your flexibility allowing me to put a collateral down while my bank transfer cleared.

For me, you did a great job.  Smiley

Basically,

Swapped out the intake fans Corsair SP120's ~2300rpms and added two 140mm exhaust fans 1900rpm
temps are ~ 46-51c  in a 20c room. Left to run overnight.

https://bitcointalk.org/index.php?topic=545642.40

Doesn't sound like a vacuum cleaner after this

J


What are your chip temps? I have two bgears PWM 120mm pushing 110CFM and a pair of 140mm bgears PWM pushing another 110CFM and it still gets hot in ambient above 75F to a point where it shuts off.

Thats because bgears are shit

Hi everyone;

I had an issue with the PSU (broke because of bad luck). Spondoolies replied to mail 5 mns after my request with : "give us your pool credentials".
Few hour later I had a SP10 configured in israel hashing for me. Thanks Spondoolies !
I now received my fresh new PSU and everything is back to normal. Thanks Spondoolies !
Firmware 1.4.3 is awesome, 1.5+TH/s with 1%-0.5% HW errors. Thanks Spondoolies !

If anyone read me and want to invest in a miner, I highly recommend SP-T. They are reliable, great after sales support and well... good at what they do.

@SP-Tech : Thank you again team, you have better after sales support than some of the biggest IT actor on the market.


Oh shut up SP-tech now you are just showing off. Cripes. LOL.

lol, every right they have to do so too! every day is a day closer to SP30...  Grin

Gotta say, best customer service of any bitcoin company so far. Better than many big IT hardware manufacturers. Also helps the hardware rocks Smiley

I used to use another Israeli company a long time ago for similar sized hardware, called RadWare, they were awesome as well for cool hardware and great CS.

Only service I have had on here that comes close is Mr Lee's group buys and hosting.

[edit] Oh and Roadstress' group buy was pretty smooth too Smiley

It's useless for people to want to develop a new ASIC.  Even if you have a good idea you have a bunch of broke dicks that will just tear apart any idea you have.  You all want a decentralized currency but in reality all you are doing is supporting China because that's the only products you want to buy. 

Bullshit.

If you actually have a product to sell, just produce the proof, people will be falling over themselves to buy it no matter where it is from.

Why can't they produce pictures and videos that prove what they say? Its not hard, they had the camera there, they had time enough to to take two crap videos that proved nothing.

None of this angst would pour down on them if they just do the minimum sensible things.

1. Full technical details
2. Good pictures of all internal and external features
3. Videos of real hashing hardware showing the machine booting up, hashing, cgminer/bfgminer screens, pool screens updating in real time etc.

Its not like its too much to ask, hell its in their interest to do it if they have a real product.

Unless they don't have anything and are trying to skim the gullible percentage. That's the only reason

I don't understand, why would you charge more for hosting a SP-10 than Spondoolies do themselves?
1932  Bitcoin / Hardware / Re: Novello Technologies new Mining System Project, prices as low as $0.3/GH on: June 12, 2014, 02:51:47 PM
Great move.

Let us see what happens next. My guess some sort of Spondoolies like rebirth. Anyone else?

My guess is a couple of dozen "investors" who never get their money back.

Hope this gets resolved soon. 6hrs for me now.
The good thing is that this only effects the stats page. I posted about the stats error to bring awareness to the problem to those that can correct it.

The mining is going along just fine.

For me, if its 6, 12, or 24 hours I don't care as long as shares are still being accepted from my miners and the pool is solving blocks.


Its not just the stats page, it delays payouts as well.

And 13% extra efficiency is BEFORE PSU so in the end it's more than 13% extra efficiency.

SP10 is ~1w/gh at the wall.

rk-box is ~1.15w/gh at the wall.

Default for SP10 is 0.85W/GH and can go down to 0.7W/GH if needed. RK-BOX is 1.15W/GH and nobody knows if it can go down if needed or not. More likely not.
I don't see why not. since BE200 chip supports a range of frequencies.

Haven't seen any live demo of it so I will be reserved until I see proof.

Theres plenty of BE200 chip based miners out there, at a wide range of freq and efficiency.

No miner is under 1W/GH so the range isn't so wide for better efficiency.

Isn't it all a moot point seeing as you cannot buy now, nor in the future SP10's?
1938  Bitcoin / Hardware / Re: Why is BITMAIN selling used products ? on: June 12, 2014, 08:47:38 AM
To be fair edgar does tend to have had some bad luck with the mining gear he has bought Wink

I've had two S2's one from batch 2 that arrived with a few cards out of alignment and after about a month the PSU stopped powering up the rig unless I removed a few boards.

So I just popped another PSU I had lying around in there and its been working fine, then I began the elaborate support dance with Bitmain, in the end they are getting it picked up at their expense to send back to them and get me out a new one. No biggie.

I also got a batch 4 from the group buy, much better packaged, everything survived intact and it mined as advertised first time.

As to the car allegory earlier in the thread wtf? How many cars do you import from China? Cheesy

Mexico mostly and parts from Canada. Or Japanese. Do they even make cars in the US anymore?

I mean as an individual buyer, what do you think your chances are of getting it fixed quickly if you imported your car from China and you found someone had been driving around in it for a few weeks before shipping? Smiley

I can "guaranty" nothing good will come of this scam

When he had the opportunity to provide demonstrable evidence of the existence of these units
He took a 10 sec video of a box with a LCD Screen and claimed he didn't have enough time to do anymore..

I'm mean fuck me! Seriously?
What do you do that is so important during the weeks/months in the lead up to selling these devices that you couldn't spare 30 minutes to record a video of the entire unit inside and out
And showing a video of it hashing with cgminer to a verifiable address?

How is it that you can't manage your time properly to allow an hour to do that?

Because the longer he spins it out, giving out tidbits and hints and promises, the more people get suckered into it. This is the bitcoin long con, its not like its not been going on for ages anyway.

If you had product you know you could sell a lot more of it if you can prove that the product is real and works as advertised. There is ZERO excuse for not showing that proof.

Anyone who buys anything, miner or hair growth oil without hard proof is a prime candidate for a Darwin Award.

couldn't find the "Picture of your mining farm" thread so i guess this will do.

phase 1



Niiice Smiley

Was but the room turned into a furriness hitting 47Degrees, the A/C units are shit anyone any recommendations on cooling that doesnt involve proper DC grade heat extraction and recovery?

Its not hard, work out how much power (energy) you are pulling out and then get the equivalent amount of cooling power.

Heres some ideas to get you going:

Heat is measured in either British Thermal Units (BTU) or Kilowatts (KW). 1KW is equivalent to 3412BTUs.

Most aircon units are measured in BTU's so I'll work in that unit.

Equipment BTU = Total wattage for all equipment x 3.5
Room Area BTU = Length (m) x Width (m) x 337
Lighting BTU = Total wattage for all lighting x 4.25

There seems to be no windows, or people working in there permanently so you can probably leave those calculations out.

Total Heat Load = Room Area BTU + Windows BTU + Total Occupant BTU + Equipment BTU + Lighting BTU

So you need enough aircon cooling to handle that amount of heat.

I'd say on equipment alone you would need minimum 100KW or 350K BTU's of cooling

It only appears that you have two of them, thats max 50K BTU if you have the most powerful (25K BTU) wall-split units, so you would need 14 of them.
