Hello. I am new to this forum and my english is bad.

I have a motherboard (Gigabyte GA-P55A-UD3R rev. 1.0). It has a "Marvell 9128 SATA 6G" controller, which is responsible for the G-SATA3 connectors. Сontroller this version is out of date, therefore i am experiencing problems when connecting to G-SATA, modern SATA III SSD / HDD. This is expressed in the following: when connected to one or simultaneously to two ports G-SATA3, SSD or HDD SATAIII, the PC, when turned on, turns off after 1 second, and turns on itself. Also, when turned off from under Windows, it turns off abnormally (recording in SMART "C0 Power-off Retract Count"). When connected to SATAII ports - it's fine, no troubles.

I would like to fix this problem and most likely this can only be done by updating the controller firmware. I ask for help from experienced members of the forum!

I enter the BIOS of the controller from under the BIOS of the motherboard. Data from there: 2009, Vendor ID 1B4B; Device ID 9128; Revision B1; Bios 65535 65535 65535 6553; Firmware 2.1.0.1316.

This board also has such a nuance that when turned on, SATA3 and USB3.0 work from PCI-E x16, while PCI-E x16 becomes x8.
Please tell me if there is a solution to my problem. If yes, help, write instructions. Are there any risks, etc. For earlier, i am very grateful to those who responded!
