Socket FM1 AMD A75 ATX board
The GIGABYTE GA-A55-DS3P rev.1.0 is a Socket FM1 motherboard built on the AMD A75 chipset. It fits a standard ATX layout measuring 30.5 by 22.5 cm and provides four DDR3 DIMM slots supporting up to 64GB of system memory.
Suits FM1 APU builds only
This board suits builders assembling or repairing a system around an AMD FM1 processor with integrated graphics. It will not accept AM3, AM3+, AM4 or AM5 CPUs, and the four memory slots are limited to DDR3 modules only.
Single PCIe x16 slot at x16
The expansion layout includes one PCI Express x16 slot running at x16, a second x16-size slot wired for x4 operation, and two PCI Express x1 slots. That single full-speed x16 link is the specification that decides whether a discrete graphics card can run at its intended bandwidth.

Questions about this item
What CPU socket must my processor match for this GA-A55-DS3P board?
The board uses Socket FM1, so the installed processor must be an FM1-package AMD APU.
Will my existing DDR3 memory modules work in the four DIMM slots?
Yes, the four DDR3 DIMM slots accept standard DDR3 modules up to a total of 64GB.
How can I confirm the onboard Realtek ALC889 audio is active after assembly?
Boot the system, open the OS sound control panel, and verify that the Realtek High Definition Audio device appears and plays test tones through the rear panel jacks.
