The Gigabyte GA-P55-UD3L uses the Intel LGA 1156/Socket H CPU socket. Any compatible Intel CPU will have the same socket entry. It uses the DDR3 memory type, with maximum speeds of up to 2133 MHz, and 4 DDR3 slots allowing for a maximum total of 16 GB RAM.
Released on 01 Dec 2009, the Gigabyte GA-P55-UD3L is now over 10 years old, which means it is extremely out of date and is based on very aged technologies. This motherboard will be dwarfed in performance by its modern counterparts, and will likely have very little support from GigaByte.

The Gigabyte GA-P55-UD3L has 8 SATA 2.0 hard drive slots. These allow for data speeds of up to 3GB/s. SATA 2.0 is a very common standard, and despite the emergence of SATA 3.0 - whose potential is difficult to reach currently - SATA 2.0 remains a viable option.
The Gigabyte GA-P55-UD3Ldoes not support onboard graphics. Any system build that uses this motherboard therefore requires a separate graphics card, or a processor that has a GPU on the same die, such as AMD APU processors. There are 2 PCIe x16 slots on this motherboard. This means it is perfectly capable of accommodating the latest graphics cards, although it is important to try and use a graphics card with the same graphics card interface of PCIe v2.x, as anything below will not reach the motherboard's potential, and anything above will have its performance slashed to the bandwidth maximum of the Gigabyte GA-P55-UD3L's PCIe v2.x. The Gigabyte GA-P55-UD3L supports up to 2 AMD Crossfire connected graphics cards for improved overall graphical performance at the cost of multiplied graphics-based power consumption as well as the price of the cards themselves. Nvidia SLI is not supported.
The Gigabyte GA-P55-UD3L has 12 USB 2.0 slots but no USB 3.0 slots. While USB 3.0 slots are so far by no means necessary, and with a plethora of USB 2.0 peripherals to choose from, the USB functionality on this motherboard should be fine. If planning on building a new system, a motherboard with USB 3.0 is likely to have a longer life cycle, however. Pro tools 10 hd user manual.

Using GA-P55-UD3L with 4x2GB DIMMs.
Triple-boot system Ubuntu, Ubuntu Studio and Windows 7.
Half the memory is shown as 'Disabled' in the BIOS screen and as 'Hardware Reserved' in all the OSes.
The DIMMs work, switching them around has no influence on the results.
This is already like this since some time, but a friend has the same PC and does not have this issue (he has not overridden the factory OS as I have though, if that is somehow relevant).
Currently using Award BIOS FH, I have tried (unsuccessfully) FC and FI as well.
Any help?
