[ANN] Spondoolies-Tech - carrier grade, data center ready mining rigs

[ZiG]

OgNasty measurements:

From the same post Spondoolies-Tech quoted.

In conclusion, the Antminer S5 is a top tier miner. It's cheaper & cooler than it's closest counterpart (SP20) and is available to ship from stock for as low as $480 on amazon.com.  I am definitely grateful to Bitmain for the opportunity to review this product and I will keep my eye on their offerings in the future.  If you are searching for a cheap, competitive mining product with lots of customization opportunities, you can't go wrong with the S5 from Bitmain.  I even purchased an additional unit for my mining operation at retail price and was happy to do so.

BITMAIN, Build a miner,  would like it should be . Along with the bottom and covered top, with two silent fan. Why do I have to take one of S3 and one S5 ,   to get a normal product ? This has to be the right S5

Agreed 101% ... That's how S5 should be...

Don't know.  My S5 units are running stock and in spec.  SP20s are running great.  The 1.7T is not reachable in my environment, but 1.5-1.6 is easy. That ability and better construction makes the SP20 worth a premium over the S5.  But how much?

Offtopic: Until Bitstamp resumes where do Europeans go to exchange their BTC to fiat? I only user Bitstamp and GOX in the past and I don't know of any other reliable european exchangers.

Kraken-not sure how reliable it is and it is in US geographically (San Fran), but , paradoxically, mostly trades in BTC/euros.

I don't like the fact that they [coinbase] take a peek into my transactions.

and who doesn't? they all do now due to regs.

With Coinbase I dont like the fact that you cant place limit orders to buy and sell, only market.  And the spreads are wide too.

Quick question: What's the yellow flashing light (9x repeating) mean?  Everything looks to be mining just fine, but noticed one unit doing this.

I use the bitcoin trader app on my nexus 7 and also running on a PC using an android emulator.  It lets you set limit orders and such.  Picked up some btc at the $258 range this weekend using it.

you can ask the question differently. Depending on your circuits, you can put one SP-20 (downlocked to ~1.27-1.3Th and 700W) AND one S5 on one 110/120v/15A circuit, OR two Sp20 at 800W (1.36 Th) on a 20A circuit. I think depending on what circuits are available and where (rooms, garage, shed) the optimal set of miners might be specific for each situation.
My take: if you like to fiddle with software and typically need good support-SP20 is for you-endless possibilities in adjusting. If you like physical mods-S5 might have an edge as you can build a shroud, try different fan combos, etc. To my ears, S5 sound (at default) is much worse than Sp20 (at least at setting 30), but S5 may sound better with a third party fan.

+1 100% agreed.

[philipma1957]

cool, but SP20's price is no longer competitive

the bitmaintech price drop for the s-5 was very big.

Don't forget you get what you pay for.  Bitmain hardware, unfortunately, now has a reputation for being lower quality.  Also their customer service tends to be pretty poor as well.

M

well I have 8 sp20's and I sold the one demo s-5 given to me.

[DiCE1904]

Kind of bummed that before my three pack of sp20s shipped, the price was reduced $405

::sigh::

[RoadStress]

and who doesn't? they all do now due to regs.

Well for the moment US laws seem to be more intrusive than the EU laws when it comes to bitcoin exchanges and while all transactions are available in the blockchain I never heard any report regarding accounts closure in Bitstamp like those from Coinbase.

Sorry for the offtopic.

$405? Where do you see that price?

...you will like them anyway 

[mavericklm]

Any way, trick, ssh or something to take out the 288W limit on sp20? ? ? ? ? ? ?
thank you!

[Digitalmocking]

Two days into mining with my new SP20s and so far, I'm pretty happy.

I'm running 3 SP20s off of two EVGA 1300G2 power supplies.

All 3 are running at 760 watts and I'm getting 1.3 to 1.35Th/s on them.  When I get home I'll run a kill-a-watt on both PSUs so I get a set of measurements at the wall.

in my home where stacking counts. the sp20 works better for me,but sell me the s-5 cheap enough and I will go back out and buy some just to tear down and fuck around with.

No thank you, we're selling only quality hardware.
For cheap open plastic stuff, look somewhere else.

reduced BY $405 for the 3 pack

So if I would of just waited a few days before ordering I would of saved $405. basically a whole month of ROI

My GB was running since 23 December until today so no excuse there. Sorry anyway! Happy mining!

that's how ROI works this days: you just sit & wait
