Hello - Is 2.5.12 a stable version?
did you encounter any issues upgrading from 2.4.x to it on SP3x?
thx
Bobsmoke, I was speaking with SPT support about one of my power supplies which failed. Michael first updated the firmware to 2.5.12 then we started to debug the issue.
Since then (3 days ago) the miner is running stable (with a bad power supply) at half a hashrate .. but I could not see anything wrong with the update.
2.5.12 is as good as 2.5.6 which was the first firmware making my SP30 to run stable. Way better than those before which, in my opinion were pushing the SP30 above the stability limits.
The main update in 2.5.x is CGminer .. which is upgraded to V4.7.0, being optimized for the SP3x units by ckolivas. It has a lower size on disk and eats less processor time.
There is also a power supply limitation to 1250W output, but with different engine settings it gives out the same hashrate as before, when running the 1330W configuration.
The unit likes to run a bit hotter, make sure you still have the fans to 80% after the update (2.5.6 had them set at 70% by default, 2.5.12 preserved the existing 80% settings).
Else, I'm still waiting for an email from Barbara with respect to the PSU RMA which is not happening as quickly as one would imagine.
However the unit is running decently flat ..
