Qosmio X770 107 PSBY5E Bios2.10 2nd SATA3 is where? +sudden shut-downs

Question

The history of fails:
After 2 years the second HDD (non hybrid) made noises and died a week later. System on C: (Master HDD) was running good (still was the original pre installed one from factory).
I decided to upgrade to an Samsung Evo 840 500gig SSD by cloning the Hybrid HDD on the Prime/Master channel. It cloned the original perfectly and I swapped the discs like this : The SSD stayed in the Notebook on the master channel and the still good working HDD in the box with spare parts to have a emergency disc for future....
like this it worked nearly 8 months perfectly. Then frequently an alert window opened with the message that the RAM will be full soon giving the advise to close some application. With the MS tool "Resscoursenmonitor" I had to kill the processes of svchost.exe and sometimes spoolsv.exe to get the load down by 50% and I could work on till next day the alert window was returning. I did run MS updates more frequent now because skype started crashing now every time somebody called me. At this stage sudden shutdowns (without blue screen) occurred with a followed reboot. There was no intervals for these deaths obvious - sometimes 5 times a day, sometimes not at all.
The system protocols showed at the timestamp of the crashes a mistake named " Kernel-Power ID41" which is not helpful. Hardware or Software problem ? To find this out, I took the original HDD and replaced it for the SSD. The first day nothing happened, maybe because it was mostly idle, so on the next day, I started to make the pc work with all the updates from the last 10 months including Skype, Java etc..... On the 3rd day it started crashing with Blackscreen as well and rebooted nicely.
A last final test should bring up confidence that it is a software caused failure: HDD out - and SSD back in, BUT on the 2nd SATA channel. A miracle - nothing happened for a week - it was just fine. Happy End ?????
With Samsung Magician quickly testing the behaviour of the SSD on this channel, I saw that the channel can do only SATA2 and bottlenecked the SSD.
According to the Intel specification page, the chipset provides up to 6 SATA ports at 3 Gb/s with up to 2 ports supporting 6 Gb/s transfer rates. Also the CPU should support the SATA III but where is the second SATA3 channel ?
Could it be the blue-ray-optical drive ?
Who knows where the second SATA3 channel is hiding??????
Does someone have the same Problems with this sudden shut-downs ?
Does anyone have the same Problem with Memory getting to full?
The manual doesn't give information about it - >> on the Master Channel the SSD gives, according to the Magician Tool, 6 Gb/s BUT after a few hours running Sandra2015 burn-in-test it hard crashed again.
Please apologise for this many lines - but sometimes a full picture is needed.
