Besides security, what performance or efficiency gains will I get from the cgminer update on my S3+ B8? and Do I even need to update?
Also because I have the overclocked from the factory S3+ B8 do I need to plug in all 4 PCIe cables or am I OK still only plugging in two? I plan on putting 3 S3s into 1 1200 watt PSU (Corsair AX1200i)
Thanks in Advance for your response!!
1. cgminer 4.6 has bugfixes for some security holes, however, in terms of performance gains, the jury is still out (see update to OP here: https://bitcointalk.org/index.php?topic=750220.new#new, suffice to say it will reduce the load on your controller.Also because I have the overclocked from the factory S3+ B8 do I need to plug in all 4 PCIe cables or am I OK still only plugging in two?

2. Running 3 S3 units at stock on a 1200 watt PSU will push it to the max. I personally would run only 2 on that.
Thanks. Appreciate the advice. Very comprehensive information!!
Since my 1200 watt PSU was able to easily handle 3 S1 Antminers overclocked to 200GH Im confident that it can handle 3 S3+ Antminers, that is unless 4 PCIe Connectors are required per miner. Ill test when I get the units and report back.
answer is no on a 1200w axi plat corsair, the psu sense an overload (most likely & will power off itself with a red light) even with all 12 pcie's plugged into all 3 s3's. that's what i experienced as it may be different for you.
yes, it is pushing the psu to it's limits. i would rather power 2 with 4 pcies with a mild overclock. * try using psu on a computer & run corsair link & untick the OCP*
keep an eye out as it does heat up very near to the connectors & i find that corsair's pcie connectors melts easily from experience.
i tried powering 1 s3 with 2 different 1200w axi corsairs & it is working fine. (have few different psu brands & had spares so i'm powering them in various configs)
I'm running a number of groups of 3 S3 Batch 7 Units off of 1 Corsair 1200axi. Been running for weeks without a single hiccup. 4 PCI Cables on each unit.
All units clocked to 237.5

I made need your advice on how to set that up
My PSU shuts down if I connect to the antminer using the splitter from 1 PCIe cable. I have had to use a single PCIe cable for each connector which means at most I can use only 2 connectors on each of the 3 S3 antminers (1 can probably have 4 connectors since i have 2 PCIe connectors remaining on my PSU).Im definitely not experienced on how PSUs work, but i read somewhere it's about distributing the power across the different rails. I had to do a lot of research to get my current connections and config to work with my prev 3 S1s and now my S3s (just using the same config.)
The Ax1200i is single rail. Your unit should have come with some 8 pin to dual 6/8 pin cables. You can use those. Just use 6 of the 8 pins on the split side.
Keep them on the same unit too. Don't split them up.

Yup. That's what I did initially with my S1s and I made sure that the split was on the same miner, but the PSU would shut down with a red light after a few minutes. When I tried using only one of the 6 pin connectors on the split cable it worked fine, so now I am using 6 cables in order to power the 3 S3s. Havent tried again on the S3 - figured I would just use what is already working. If I do end up needing to plug all 4 PCIes per miner I may try again, but for now it's working fine so I'll just leave it
Thanks though - good to know it's working for you and that if I need it SHOULD work for me as well
? Facts are just that:
