I got two S1 for $200 with free shipping only 3 months old. I got those to learn this bitcoin stuff and to see if it can pay itself back. If so, I will go straight for 2x S3 as soon I get the chance. I am not sure if I will be able to save up $540 for an S3 mining with those two S1.
Also I was worried to put that kind of money $500+ into something I am yet sure how it all works. Plus the room that it will go in I will need to find a stable temp or if I need to add fans etc... I would hate to burn new S3 testing so my S1 are my testers.
I live in FL. I have a "Florida Room" on the back of the house that is not well-insulated, only has one AC vent, and I keep it closed year round (unless we have guests trying to sleep back there. I have 2xS1 and 2xS3 mining happily back there 24x7 venting directly out the window. The room easily get's over 90 deg F almost every day, and they do not care. The S3's have a slight overclock to 225, and BTCGuild hourly charts show they both fluctuate between 440GH and 480GH. The S1's are currently underclocked and undervolted (as I mentioned previously in this thread), but before I got my S3's, the S1's were both overclocked averaging 195GH each (@387.5Mhz). The only troubles I've had with them were entirely power related. Lesson is, make sure your PSU(s) can handle the constant load, and make sure your home's electrical circuitry can handle the load. I recently got new cables in that allow me to put my miners on an extra 220v circuit that I was fortunate enough to have back there. Doubling the voltage halves the Amps required for the same power, and supposedly PSU's are more efficient at the higher voltage too.
That being said, keep being careful, and don't blame me if you burn out your miners. Just make sure you can properly vent the heat they produce, or any room with or w/o proper AC will be hard to keep cool.
Hey Thanks for the information much appreciated. I am just hopping that having 2x S1 for $200 hopefully was not a bad idea since most people were telling me, I should had gone the S3 route right way. My worried would had been burning those S3 and now having a debt with no way to generate money. So, I trying to play it a bit safe here by getting 2x S1, an trying to keep them cool using a direct fan and messing around with the settings etc... I ended up purchasing a room temp digital meter to keep track of unit ambient temps. Other than that if the S1 manage to get ROI, I will then put an order for 2x S3. I have to first see if they will or not.
The basement room temps so far has been 82 degree in the day and 75 degree by morning with no devices running there. I may need a fan if I run both S1 from there. In the winter, I will put the S1 on each of the kids rooms as space heaters. XD and have the other on my room that way I can drop the house overall heating down at night. =)
