Sorry to hear you are still having problems. What model Dell do you have?
If you enter the Dell Tag number on the Dell support website, it will provide you with their documentation for your system as well as the appropriate drivers they provide. Check the User Guide and look for a Service Guide which is sometimes listed and other times you need to search for it. Usually between those documents you can determine the more technical details of your system to determine which SATA ports are which. You could also try connecting another drive to a SATA port and checking Device Manager to see if it shows it connected to an Intel port (just make sure it does not have a bootable OS or it could cause problems).
As for your drivers, Crucial_AgentC mentioned in your linked thread that the MS SATA drivers work best with Win7. Make sure to install the chipset driver first, then your other ones for the SATA controller, Intel RST, etc. If you do another clean install of Windows, then install them one at a time to see how the system behaves. The Intel RST driver has been known to cause issues, and other times solving them so test before and after. Due to the way Windows handles drivers, once you install them there is no easy way to completely remove them since they seem to hide the remnants on the system. Make sure the Dell's firmware is up to date first.
At least the UDMA CRC errors have not increased which is good news.
The SATA controller your SSD is connected is in IDE mode. You need to set it to AHCI mode, but doing so will break Windows. It may be possible to prep Windows for this change, but I'm not sure. Check the other threads on here as I know there were instructions to do this or something similar within the last two years (most likely posted by targetbsp or bogdan).
I'm concerned about your memory. It appears it thinks there is 16GB of RAM, when in fact it shows you have 6 sticks installed totalling 20GB (two sets of 2GB and four sets of 4GB). Most Dell systems I'm familar with usually only have 4 memory slots and those which have 6 slots usually cannot be completely filled. The documentation on this can be confusing. Also it is better to put the larger sticks in the lower slots if you are mixing them. You should definitely check the official Dell documentation (User Guide and Service Guide) for upgrading memory to make sure it is installed correctly. If your system can utilize all 6 slots, then it appears your 2GB sticks are not being recognized fully or perhaps one of your 4GB stick is bad.
If on a cold boot you press F12 during system POST and let the system idle there a minute, then select your Windows SSD will it boot? If the drive does not show up as an option, then in the BIOS change the POST configuration to "Thorough" to allow the system more time to initialize everything before booting.

First of all, you never provided any details of your system make and model. Its almost impossible to guess on what port you are reffering to. Please provide more details so that someone can guide you in right direction. Just reffering to colors on the port does not make any sense.
