i didnt buy from the official site since its really hard to get bitcoins (I live on a Caribbean country) anyway i've learned my lesson but for now i need to solve my issue, so give me some ideas.

0.7-0.2=0.5
0.5 is less than 0.58
Capisce?

...or you could just stay on the current version (same as mine) and do the SSH route with "vimetc/config/asic-freq".

I agree with most of what you say, but isnt the picture and example of a different unit?  Also you are using a .13 cost for electric.  For example I have .07 which would double my earnings.

Don't get me wrong I am a strong supporter that the current change of bitmain to preorders ( 20 plus days out which is an eternity in crypto world ), not lowering price ( like they have done in the past to help their customers have a chance at a 100% ROI ). no coupons for returning loyal customers etc is not a good change.

Just want to help people make the best decisions....

- Note - The Net hash has gone from 132 mil to over 195 mil in last 22 days.  It makes you wonder about the lack of supply from bitmain all of a sudden for next 30 days and yet some other company is bringing so much hashing power out?  Wonder if that new hashing power suddenly goes offline when the s3+ starts to ship or all those new s3+ units get added on top of that staggering 60 million network increase.  I think I would be more concerned if it came off the network slowly as we approach the Sept 20 date.   Giving conspiracy guys some very damaging ammo.

I just don't understand why other people are so obsessed with other people's financial decisions. Why does everyone need to make a profit mining? Why does everyone assume their calculations are correct for another person's scenario? I also love how these ROI calculations never seem to take into account "salvage value" of the old equipment, expected increases in the value of BTC, or the enjoyment some of us get from this hobby. Do you go to the guy down the street who's spending a bunch of money restoring an old Camaro or Mustang that he's never going to ROI? No one is saying I ordered a bunch of S3's and I'm going to get rich!

The world is full of companies who charge too much for product and still manage to find customers, and the world is full of people will to pay more than they should for products. Please accept it and get over it. If anything take advantage of the opportunity and start your own hardware company and undercut everyone else and be a hero.

Indeed.  243.75M is the new 250M; at least for me anyway.  At 243.75M, my units draw less power at the wall (413W at 29C) with lower HWE% and better hash rates than at 250M.  Go figure.

Thanks to philipma1957 for the additional frequency codes.  Now, if he could only do something about my fan speed readings ...




To reiterate, each is only powered by a dedicated Corsair CX500 80 Plus "Bronze" PSU with only 2 PCIe power inputs:

People point out that items won't ROI because...

A)  They hope the manufacturer sees that fact, and reduces their pricing to make it so it will.

B)  Just in case you happen to know some tricky to suddenly make the miner earn twice as many coins for the same gigahash.

and...

C)  So they can get you to convince them that ROI doesn't matter and they should go ahead and spend that Bitcoin burning a hole in their pocket.

I think ROI should be classified as some kind of mental illness......some kind of incurable nervous twitch......

As in: " Oh, you've got ROI - that explains it, sorry",  or "My ROI is killing me".

ROI = Return On Investment

or

ROI = Rate Of Imagination

... according to your link.
