'The right to privacy matters'




which one of those SLOTS labeled as 1,2,3,4 are the slots that power the back chips ?
Thank you !

Slots 1 and 3 powers the two back ASICs on each board

Back being farthest from the fan or closest?

the closest to the fan run hottest so they would be the back ones.

this is true due to the fan pulling the hot air from the  asics closer to the pcie jacks (front asics)  those two  get cool air  from the grill by the pcie jacks.

90% sure I have it correct.

Interesting observation related to
http://en.wikipedia.org/wiki/Active_noise_control

i have three Sp20 and one S5 in the same room with S5 running with Noctua and Scythe ultra kaze fans (push pull).
I suddenly realized that i have much less noise in comparison when I had just two Sp20 and one S5.
Upon measurement, approximately same amount of noise is coming from each Sp20 at ~69dB and a little less (maybe 64db from S5 with two fans) with all measurements at 1 ft.
However, at the door, just four feet away, the noise already drops to just 61 dB, which is a much faster drop comparing with a single machine.
My point is that most likely some of these miners produce the "anti-noise" (see article).
I set up (accidentally) my three Sp20 in such a way that one is at fan 10 (fixed), one at fan 6 and one at fan 14 (these two on auto).

Right now with all four miners running, I have just 51dB ten feet away and can barely hear them- a great improvement.
My point is that by having multiple machines at the different fan speeds they might produce a canceling anti-noise and the whole setup would be less loud (at least this seemed to happen in my case).

My dog has ability to move and see at ultra high speed (at nearly 150 FPS). Thats my conclusion after witness him doge a light spark from my fireworks by bending down and lick his balls.

Anything wrong with my conclusion? Should i test this with a Glock?


PS. you didnt understand jack about sound wave let alone calling something "Active Noise Cancellation". Go to a Cinema, buy all the seats then start experiment listening at every seat.....

Is it possible to change to PSU efficiency in the formula that calculates "wall watts" ?
I know the preset one is 0.90, but mine are 0.93
If I can update that number in the firmware, I'd have more correct readouts.

Has anyone that has upgraded to firmware 2.6.9 seen slightly slower hash rate? I've flashed 6 SP20's and everyone of then is  10-20GH/s slower vs firmware 2.6.4. Just curious if anyone else is seeing the same.

Yep the same behavior. Less aggressive with the hashrate even if the temp goes down.

On auto fans? Or on any fans?

I tried auto-fan and it's too hot here for my setup in my home. The fan went to 90% on both machine. I run one of them at 40% and the 30% (to avoid an annoying resonating noise)

Hello,

I had an increase in problems in one of my SP31...the Loop9 keeps being disabled.
I made 2 upgrades yesterday and is now at version 2.6.1 ... but looks like it continues - please see below:

FW Version 2.6.1

Temp Front / Back T,B 18 °C / 62,47 °C
Socket Voltage 224/225 volt
Fan Speed 80
Start Voltage 0.655 / 0.655
Max Voltage 0.75
Max Watts 1290 / 1290

LOOP[9] OFF TO:0 (test serial failed or something)
27: disabled (i2c good, no OC)
28: disabled (i2c good, no OC)
29: disabled (i2c good, no OC)


messages log has:
Jan 25 21:45:15 miner local1.warn minergate[855]: Loop BAD DATA (0) on 9
Jan 25 21:45:15 miner local1.warn minergate[855]: loop 9 disabled (code 5)
Jan 25 21:45:15 miner local1.warn minergate[855]: Critical: ^[[31mBad loop 9 = set loop as disabled^[[0;0m

Any ideas? .. hard reboot sometimes resolve but it comes back after a while ....

thx

Sketchy part is that the fees are currently about 75% of the BTC mined, and the provision allowing them to terminate the contract with no refund to the customer puts the consumer in a weak position, actually a little surprised Spondoolies partnered with them given the gray area the contract puts the consumer in..

  yeah.  I think it is pretty expensive.  you do not own anything physical just a contract that can be cancelled.
the s-5 deal is better you own an s-5 not a contract. plus it is far cheaper per gh to buy it.  and a little cheaper by gh to run it.

Genesis made the first proposal for cloud  hash via spondoolies.

Bitmaintech is making the s-5 proposal own and host  via lee on this thread below:

https://bitcointalksearch.org/topic/lee-group1980-the-sales-of-first-batch-hosted-antminer-s7psu-included-934581

Genesis needs to do better or won't sell much.

I never understood if you have profitable hardware and set up a farm why would you then offer mining to others via cloud? The only other reason is that the hardware was not paid in full and cloud farm kicks back the supplier.  After dealing with Hashfast I just stay far away from these. I have had great dealings with Spondoolies so far just hope this works out for everybody.  

IMHO, cloud mining is simply shifting the risk of ROI and etc onto the customers, so that the operator of the cloud mining can pocket the roi and potential profits months ahead and leave all the risks involved solely onto the customer Grin   
and if it all fails then you simply get a message saying " sorry due to unforeseen circumstances cloud mining is closed now" .  At least if you buy the miner and all fails, you can use it as a door stopper or something, with cloud mining  you don't get jack sh!t for it  Cheesy

Put this way, if I had a money printing machine that is profitable why would I want to share it with someone else? would you? unless you know that you would never ever roi so it's better to offload it to a greater fool  Cool

Hi Guy
So i want to buy Genesis-mining , but you have to sign up a contract before you see Information.
What is that?
How can you recommend such a Company?

i looked at the contract and wasn't terribly impressed.
its a lifetime contract with a $/GH/day fixed maintenance cost (The math worked out to something like $60/TH/month (or about $120/kW/month assuming the hardware is SP3X series)

Quote
"2. Remuneration
As a consideration for the Services the Customer agrees to pay to the Service Provider an amount of (the "Fee"):  
a. 0.449 USD per GH/s upfront
b. USD 0.0019 per GH/s and day, deducted on a daily basis* from the generated Coins
4. Term
This Agreement is entered into for the term indicated above.
The Service Provider may terminate this Agreement with immediate effect if the Coins generated in the preceding 20 days do not suffice to pay the Fee under 2.b above."

ie: once the fees>daily revenue, the contract is almost over, with a 20-day maximum period for daily loss before the agreement is terminated

Not terribly impressive considering that $449/TH is the approximate pricing of the SP3X series, in which case the hosting costs are about equal to $0.17/kwh. I personally have colocation elsewhere thats <$0.13/kwh and the hardware is actually owned by me.

Genesis is too expensive.  The deal offered by lee using s-5's that you own allowing for paypal payment is far cheaper.

$340 for 1 s-5  they will run it at 1150gh and charge you 43.60 for power.  

to match this deal genesis needs to offer 1000gh at 295  and charge you 37.90 for power.

Now I love sp20's for my home and I am running 9 of them.   I only run 1 s-5 at home.

I also prefer spondoolies-tech over bitmaintech as a company.

But the numbers on genesis cloud are just far too expensive.

The nature of mining is very competitive. 
I could buy from lee with paypal get a small paypal discount 2% time the order and have about 40 days to pay it. I would also be protected by paypal for 45 days.

genesis needs to step up its game to compete with that offer.

Hi Guy
So you said in miami you would not go into hardware, but keep an eye on next gen.
When this could be?
Can you make a example?
Thanks
