For some time SIA was very profitable to mine but there was no public pool existing and difficulty became very high. I believe it's because of the FPGA farms that can use Wolf's implementation. Idea was to have in parallel some mining that will cover the electricity costs and check the luck with SIA's high variance. I did mining of SIA before and I know that down clocking the memory doesn't change the hash rate but lowers the power spent, meaning that it is very relaxed on GPU memory and can be mined in parallel with ETH. Last week price peak of SIA and calculation of 3 times more profit than ETH was a signal to start. Three rigs used, first with one 280X and 7870, second with 4 280X and last one with 3 280X and one 290. Win, Claymore dual miner in mode 1, siad 0.6.0 and precompiled sia_gpu_miner. With sia miner intensity up to 27 there were very low sia hash rates (280X in range of 50Mh/s) but almost no change in ETH hash rate. Intensity 28 dropped ETH hash rate at 35% of normal level and gave 510+ Mh/s on 280X and 600+ Mh/s on 290. More than 3 days passed and I didn't solved a SIA block, SIA profitability went down close to ETH, difficulty continue to rise, ambient summer temperatures gone higher,... so I gave up. Undecided  If someone wants to try and/or believe more in SIA than ETH can share dual mining experience. Or maybe Claymore can make ETH-SIA dual miner where SIA intensity could be fine tuned.
Here are some screenshots during and after unsuccessful try...


Dun blame me! I never finished one for Sia; if someone has an FPGA farm and is interested, let me know, though.
Nano /fury has good hashrate with sia.
My fury-x (I have two) is doing 1800mh/s @stock with gominer and 1700mh/s with -40% powertune and -85mv : nano would be around @1500 mh/s


Wolf0 has a better miner.
I believe the recent increase of hashrate correspond to some major nano farm switching from eth to sia mining.
The difficulty is so high now that I didn't find a block since more than 7 days.

That is what I call clever mining.

Also, not so long ago everyone could buy SC for 3 satoshi...

Not anymore... I'm missing the times when PC with two cool 7790s was making a block every second or third day. I was planning to keep all 5 milions SIA I mined but "lost" all of them daily trading during some wild SIA rises. Not whining at all because made 2 more millions with daily trading and "lost" them on 30 and 60 satoshi values. Not bad for old small PC doing side mining. I will maybe go back to SIA mining when Intel releases XEON chip with FPGA. See ya SIA...

omg what windows is that ??  XP ??

Win7, colors washed because snapshots are from TeamViewer sessions.

First one before...



...and afterward, more cool and relaxed.



Second one...





And third...
