Ok mathmeticians, figure out the answer to this one. Let's say you had one of these 500 Ghash miners, and you could time travel back to January 2009, when the difficulty stayed at 1 almost the entire year. And let's say you put this miner to work, pimping out the hashes like a mutha. Now here's the math part: since BTC is limited to a 4X difficulty increase with each adjustment, would it be more profitable to: 1. let the thing hash non stop and let the difficulty rise over a few adjustments to its equilibrium point,... OR... 2. once the difficulty rises, shut off the big miner for a few weeks and let difficulty drop back to 1, then turn it on and run it up again? I think letting it run non stop, even with higher difficulty after the first few adjustments would be more profitable. Math it out! ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) Do you have a time machine handy? You'll have to convince me first, LOL http://www.youtube.com/watch?v=SR5BfQ4rEqQ

S2 delivery date pushed again 30th
That's how bitmain works: you give them money first, then they send you a machine two days later.

Hash power improvement on hardware can't keep up with the diff.
As someone said above, no ROI, no care. And it looks like it will be the case.
you sir are likely correct....er due to bank issues...i'm a legal miner in usa (sigh) have to pay for mining profits as income (gross income 25% taxes like the rest) er those of you not in my boat run away till hopefully they fix these IRS guidelines from 2013 to something more sensible in 2015 (i think they will..just say at that point 2015 gee IRS it was a very very good year if you wan to report) heh ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) anyway MY ONLY angle is that I can get off 25% in real $$$ towards actual taxes paid thru equip depreciation (and have credits on such from last year) so i got a spondoolies sp30 w/o being in my situation it makes NO SENSE to get equip in the foreseeable future imho in order for BTC to survive this massive equip dump and difficulty rise the price MUST go up for BTC thru increased demand or we are all in trouble and yes I may barely break even on the sp30 ROI wise due to my above (sigh so lonely) position of er ahem being a legal miner (i feel so dirty)...but i suspect after all is said and done and it probably will end of life by Dec 2014 at the rate of equip dump i will take a loss so yeah any equip you buy at this time thru fall will likely be a loss vs just buying btc imho ...it may level off etc after fall but I think it is gonna get really really ugly this last 1/2 of the year but then again they are such 'cute' little boxes..the s3's ...nice whirly sounds...pretty LCD's so cuddly . ack must resist ..its a trap ack Searing A. For all new purchases of computer equipment, you can deduct up to $105,000 of the actual purchase price, under what’s called Section 179 of the IRS code, which has to do with equipment depreciation – as long as all of the equipment is purchased by December 31. This is for any business of any size. http://www.startupnation.com/articles/small-business-tax-advice-computer-deductions/

When you shut the machine off, your time-machine-less peers will still be minig with their CPUs at difficulty 1 rates. You've quadrupled the difficulty, so it's going to take about 2 months for the difficulty to decrease. The other thing you have to worry about is pissing off 2009 Satoshi. You don't want to do that...

My last 3 S1 boxes came 5 weeks ago, total price BTc 1.07 for the 3, that is 540Gh I hope the S3 is a better price than this, 2 steps of difficulty increase since then, has reduced my income to the same as before they arrived.

Yea, I am currently talking to someone from the FaceBook page, BITMAINtech. It looks to be the most legit one, however; the person I am messaging just requested I send them 1.057 BTC to a BTC address they just provided.
.97 for the S3 .087 for Shipping to US
Which I'm not going to go.
I requested that they create an order for me on the main Bitmain website under my profile and then I would submit a payment.

Well, I just emailed webmaster@bitmaintech.com with a copy of the conversation asking for them to verify the transaction and then I would go ahead and send the BTC. We'll see what they say. I'm not willing to risk 1 BTC yet.

Basically, from simple maths, 1 CX750 can run a 180GH/s S1 and a 500GH/s S3 with no problem?
S1 normal speed <--- 360W S3 normal speed <--- 390W
360+390=750
Did I do anything wrong here?
You math is correct. But in practical case you need to allow some free room in between the power supply output and power consumption. There 360 and 390 are rated power consumption from the manual and they can be lower or higher slightly for each device. So, I will advice you not to load one S3 and one S1 in to a 750 Supply. Most probably you may need to undervold and downclock your S1 in 2 months and that will make you run if S3 is not overclocked. Better take a decision after you secure the S1 and S3 if you already bought the 750 Power Supply Unit. Else buy a Dell Server PSU and mode it or buy an already moded server psu. Better stick to 1000W or above. Cool! I got the cx750 for my s1 already. Probs under lock once I get my hands on an s3. I don't know specifically about the CX750, but with most Corsair PSU's I have used this would not work. I know it's not advisable, but it just plain may not work at all. It seems if I load a PSU with multiple miners I need to be at least 10 -15% under the rated wattage or the PSU will just turn on and then off as if overloaded. Sometimes this is solvable by starting one device, letting it warm up, then adding the second. But there seem to be safety mechanisms to prevent you from pulling too much juice. I always try and be 100-200w under the PSU rating. Then I don't have issues. For what it's worth....

I've managed to run two overclocked S1's on a Corsair CX750M no problem although its not advisable. I've also had good luck with the corsair HX750, and the EVGA SuperNOVA 750G2.
I just hope I have the same result with the S3's. - Edit: When we eventually get to underclocking them.
