Is anyone else putting their S3's on LeaseRig?  I have a couple on there and everything works great using the bitmain original cgminer.  However, if I replace that with the new cgminer Ckolivas posted I get very erratic behavior when someone rents the miner.  Things like low or 0 hashrate, it reboots, or otherwise just stops mining.  If I swap out Ckolivas' new build of cgminer with the Bitmain original it all runs fine again.  

Am I missing something?  Setting something wrong?  

chmod +x cgminer

Did you make it executable?

bitmaintech is crazy to sell at the current price  the deal above is far better.

wait a minute here is lower

I can buy s-3 miners on ebay for less then I can buy them from bitmaintech.

 Last week I paid 240 usd for 1 s-3 miner  

at  358  a coin  2 miners to the usa New Jersey are 1.539  so 1.539 x 358 = 550.96 usd for 2 that comes to 275.48 usd a miner.   I paid 240 and got about 11 usd back in discount so

229 from ebay with a 45 day ebay warranty or 275 from bitmaintech and no recourse since you pay in btc.  makes no sense at all.

HA HA HA

just saw it now they ask shipping for two miners for EU 0.419 BTC

Yes am going to proceed with my order now bitmain  just wait for me

Sorry to see this company going down....

Lucky.  Mine actually went the opposite direction.  My 3 S3+ Antminers were steady at 478-500GH/s and after the update consistently below or just under 450GH/s

well, seems it did some magic to one of my S3s, before it was stable at 478 (250 MHz) now, its at 501 after almost 1 hour running...

how do the installation???
478 or 250

?
for 500 gh???

On your Excel spreadsheet you show Rockminer R3 Box (4) having a total hash rate of 2.7 THs (or 675 GHs per unit), but Rockminer's site shows their hash rate to be 450 - 480 GHs each.  Multiply this by 4 and you get 1,800 -  1920 GHs, or 1.8 - 1.92 THs.  Do these actually Overclock up to 2.7 THs?  That would be a 40% hashing power increase over stock (480 GHs).
Secondly, you show the Rockminers as being overclocked at the astounding rate of 2.7 THs, yet the other miners are shown stock.  This isn't Apples to Apples.
Your work looks great, I'm just not sure it's completely accurate or unbiased.

After what I learnt from the S4 investigation, I checked the S3s, and they have a very diminished version of the problem with pools that start at low diffs. Here's an updated binary for the S3s.

This might make startup/pool switching a bit smoother, especially if your pools start at diff 1 and take a while to increase their vardiff.

EDIT: Hashrates even seem a little faster after a few minutes...

EDIT2: No it's not any faster after longer running, it's the same overall performance. Only the startup won't overload the S3 controller on low diff starting pools.

This always happens when a company opens cloud mining. Their prices need to raise to make the cloud mining look like a better deal. Still, with the current price of BTC, the S3+ is cheaper if you consider the cost in fiat.

There are much better deals currently available: Rockminer and ASICMiner Prisma are two.

I use the following spreadsheet to compare apples to apples. I hesitate to share because well, people will freak out because it is not completely accurate in its forecast, but it does use an industry scaling factor, which will probably be overrun unless BTC goes up. I will probably adjust the scaling factor for myself.

You need to understand excel to use it, but essentially, when I go in, I update the difficulty, day and price, unless your electricity rate matches mine, you'd also want to update electricity $/kwh. I then click on the name of each miner, and it takes me to their website where I double check the price. If the principle cost is fiat, I list that bolded, if BTC, I list that bolded. I also use a calculation for the s&h if in BTC. The last three columns are where I compare apples to apples. The notes explain much of what I was thinking when I programmed it the way I did. You'd want to update costs for PSU and other. I have my preferred units that are essentially priced here.
