Re: Bitminter bitcoin mining pool - Pays TxFees, Merged Mining, Fair PPLNS rewards
I'm not sure how familiar you are with the pencil mod but you can mod these in either direction, undervolt or overvolt. The idea of undervolting (what i've done) is to lower you hashing power and your power consumption at the same time. The way the S1's work as you lower both the power consumption lowers faster than your hashing power so you can increase your hash per watt. So far everything is working fine. What you loose is overall hashing power, you gain in efficiency. I think I might actually be throwing less errors (as a percentage of hash) than I did before the mod. Either way I've always had a really low amount of errors.
The nice thing abotu the pencil mod is that its really easy to un-do so when (not if) the price of BTCs goes back up sufficiently high enough I can un-do the pencil mod and overclock these back up for full raw hashing power.
Let me know if this answers your question or if you're interested in hearing more.
Didn't realize the pencil mod worked to under volt them to improve Ghash/Watt. That makes sense. Thanks for the explanation.
Just simple numbers? Mine went from 400w/200gh to 180w/140gh Actually quite a bit more efficient. HW errors on all units under 1% (well under for most) You may have to "re-do" it a little after a couple of days once the lead cures, but mine have been stable for about a month now
Re: Bitminter bitcoin mining pool - Pays TxFees, Merged Mining, Fair PPLNS rewards
The shift size isn't going to affect pool hopping, PPLNS is still safe from pool hopping.
Making the shift size extremely small I think would be a bad idea. It would scare the ones that are shocked to see a shift with zero pay. I have to balance between that and the people who think if 10 shifts take 5 days it means they have to mine 5 days with lousy pay before proper pay starts. So I try to keep it somewhere in the middle.
To be honest? That is exactly what I thought... It is what as been keeping me from bringing more gear online on this pool. At this rate, I'd use up half a difficulty level bringing up my "share per shift" and I just can't afford it. In my other pool I'm being paid per share and if I add more I get paid more.
Where can I read how this actually works?
Definitely a negative to not have the S2 upgrade option. I own S1, 2 and 3... Only my S3 were bought new from bitmain. the S1 upgrade kits were priced NOT to sell. They were priced to match the S3 pricing of the time and it was better to buy the S3 direct.
with the S2, I had really hoped to be able to upgrade them as the cost "should" be less (no case/psu/possibly even backbone...)
But now, horribly high price on S4 (the reason doesn't matter - price fixing, exchange on BTC - fact is it is too high) and no kits for the swiftly ailing S2 - and coupons give no help to a second hand owner.
Even with the current price of BTC, I was enjoying the relationship with bitmain. This situation effectively cuts me off. No choice. I'm not mad... just sad.

Re: Announcement: Bitmain launches AntMiner solution, 0.68 J/GH on chip
Hi CrazyRabbi,
We have no comments before looking into your case, it is better you PM us your order ID and tracking number to double check.
It is no possible that we didn't process refund if we agree to a reasonable request.
Miners must be shipped out if we didn't accept the request of refund.

Just to confirm: Are you already shipping S3 - Batch 8? Thanks.
Re: How to determine which blade in an S2 Antminer is defective
looking at the S2 from the front, I believe the blades are numbered from left to right 1-10 (not counting the controller board of course. Sometimes just re-seating the board in the slot does the trick...
Still just getting going on here for sure, but thought I'd share - probably set this up and reset it up about 10 times now, this is where we are sitting for now - Rigs all vent into the closet over a trapdoor into the crawlspace. have a couple fans sucking the air out into the trap door...(Ideally I would vent the heat up but the floor is where the hole is....)
have 5 more S1 in the garage but farm is 12 s1, 2 S2 and 6 S3 now - pulls about 9200w for 7.2 gh/s

Re: Facilities with $0.02/kWh in Seattle or Washington State
Look here at Grant County rates:
http://www.grantpud.org/customer-service/payments-billing/rates-and-fees
specifically, 'Large General Service Rate 7 '.
200kW minimum load is a bunch of Bitcoin miners.http://www.grantpud.org/customer-service/payments-billing/rates-and-fees
specifically, 'Large General Service Rate 7 '.
200kW * 24 * 30 * $0.021 = $3024 / month minimum
You better be mining on a huge scale!
Also as others have said, even on this scale the dreaded words are still there "TAX ADJUSTMENT: The amounts of any tax levied by any city or town, in accordance with RCW 54.28.070, of the Laws of the State of Washington, will be added to the above charges. "
At my place that is over 3 cents/kwh
