I have two S3's, received last Friday. One of them hashes at 440GHs at stock speed (218.5), so I'm fine with it; however, the other hashes at 400 GHs at stock. I've been trying different things like putting it on a different psu's like ATX, Dell/HP server, but nothing helped. I'm taking notes on different clock speeds on this one:
Frequency GHS(avg) Temps HW Watt (Kill-A-Watt) ASIC Status
---------- ---------- ------- -------- ------------------ ----------------------
250 487.26 41, 41 2 428 Chain#2, 1 "x" on the far right
237.5 423.55 39, 37 38 367 All OK
225 422.69 39,36 7 364 Chain#2, 1 "x" at 2nd position & 1 "-" at 8th position from left
218.75 403.58 40, 38 0 355 All Ok
After editing the asic-freq file, a reboot command was issued. All readings were take at 30 minute mark. PSU is a Dell Server Power Supply 750W. All 4 PCI-E cables are plugged in, even at stock frequency.
Yes, it took me over 2 hours to finish writing this post.
I'm setting the frequency at 250, seems to be the sweet spot for this S3.
At what frequency would you run this at? Why?

so you spend 940 usd worth of mining equipment for $16 aday?
Why do you care and why are you even on here. Go away. It will probably get ROI in 3-4 months and thats not including resale value.
Just trying to understand why bother?
I would come up with a killer line and rip you for the blasphemy written,but I often ask myself the same question.
Here is a possible future for 2 s-3's.
Now if I put 950 usd in a bank I get 1% at best so my 950 becomes 959.50 in 1 year.
In my case below my 950 becomes 1008 in 7 months. I don't count internet I have internet. I don't count psu's I have them. I do count cost and power.
1) So I do far better then a bank..
2) There are tax breaks in the usa for mining that do not occur for buying and holding coins.
3) upside coins have been known to have big bull run-ups. under 90 in Sept 2013 to more then 1100 in Nov 2013.\
holding coins will make profit as capital gains, but mining them will create income that is subject to self employment tax. In the usa So depending upon your circumstances you may want to pay into Social Security mining allows this if you profit and report.
