About underclocking, what is the lowest freq?
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?
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.
Be very careful, it's not the total power consumption that's the issue, it's how much current each 12volt circuit can deliver. Read the numbers on the power supply and understand what each connector can actually safely supply, or you risk a meltdown.
Here that will not be an issue. Corsair CX750 80Plus Bronz rated power supply gives above 85% efficiency above 50% load (230V AC).
For Both CX750 and CX 750M the single 12Volt rail supports upto 744W thats why I said to undevolt/underclock the S1 slightly to accommodate it.
S1 can be underclocked successfully till 160W to 166W as of now.
After that someone is trying to undervolt further to keep it running.
After S3 you will get 744 - 390 = 354W which can easily and safely accommodate and underclocked S1.

Always, make sure to check your Power Supply hardcopy Manual comes with PSU for 12V Rail Specification.

I am not arguing with you but, @ 500GHs these units will net you $18/day and assuming another 25% diff increase $14/day. After that, assuming continued 25% diff increases (which I do not expect) it would get very ugly.
I will semi-agree to disagree. My calculations do not take into account power costs or pool fees (use http://eligius.st/ if worried about pool fees). I am pretty confident that my math is on track my friend.
Well you're wrong.

Your current earnings if you had an S3 hashing this very moment is $11.00 per day. And in 2 days it will be $8.80 less power cost. And that's assuming that your pool of choice has 100% luck and the price of BTC doesn't change.
My bad xstr8guy. 500 Ghs will get you $11/day today. Assuming continued 25% increase that means $5.75/day in August. Ugh.
Yes, it's pretty damned dismal. I'm done buying any new miners unless there is some massive breakthrough in ASIC development. I'm just hashing with what I have and watching my earnings decline every adjustment. I couldn't add another watt to my circuits anyways. But I can't help but window-shop and wish.

DO NOT BUY THESE ASICS!!! I keep telling you people!
Right now, at 13.4 billion difficulty, a 500 Ghash miner will get you 0.01868 BTC per day! That's it!
And when the difficulty adjusts to 17.1 BILLION in 3 days, it will make 0.01471 BTC per day!
At the current price of $568 per BTC, that is $ 8.35 a day, before power costs and before purchase price.
ROI - NEVER!!!!!
Send your money to ME if you are so determined to piss it away on something!!!!!
At least I will invest and spend your money wisely, instead of letting it go to some ASIC company owner laying on the beach and laughing at all the people who bought an already obsolete miner.

If the unit costs $568 and I am earning $8.35 a day.. that's pretty good... >.>...
And 10 or 12 days after that you'll be making $6.60 per day. 10-12 days after that it will $5.25 and so on and so on.

spazzdla very dumbly didn't read my post very well and assumed that $568 per BTC (bitcoin) meant $568 for this S3 miner. He was wrong.

No, hardware proliferation caused the diff. (number of hardware units).
Hash power improvement in a single unit/chip can't keep up the diff. rise caused by this proliferation.
Long term, mining bitcoin will be like selling chewing gum. You'll have to work pretty hard to get almost nothing.
Assuming you start with one S3 on July 1 (with BTC @ $600) here is what you can expect during July; .3789 BTC or $227.
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.

Hash power improvement causes the diff. People think more hash is better and get proved wrong every diff rise.
What you need to aim for is the most BTC per kWh. but that doesn't fit the more hash is better mindset.

Actually selling chewing gum is very profitable. For example "Britney Spears has found herself in a sticky situation – her old chewing gum is being offered for sale on eBay, reports the Associated Press, noting that bidding on one piece of gum chewed and spat out by the pop princess, 22, reached $14,000.
