Detailed Specifications

To really appreciate what the Gigabyte GA-H55M-UD2H brought to the table, let's dive into the nitty-gritty details. Understanding the specifications helps you gauge its capabilities and how it stacks up against modern motherboards, or even its contemporaries.

CPU Support

First off, the CPU support. This motherboard is designed to work with Intel's LGA 1156 socket processors. Specifically, it supports Intel Core i7, Core i5, and Core i3 processors based on the Lynnfield and Clarkdale architectures. This means you could pair it with a range of CPUs, from the entry-level Core i3 to the more powerful Core i7, giving you flexibility in terms of performance and budget. It's worth noting that while it supports a decent range of processors, it's limited to the first generation of Intel Core processors, so you won't be able to use newer CPUs with this board.

Chipset

The heart of this motherboard is the Intel H55 Express Chipset. The chipset is responsible for handling communication between the CPU, memory, and other peripherals. The H55 chipset was designed to offer a balance of performance and features for mainstream users. It supports features like Intel's Flexible Display Interface (FDI), which allows the integrated graphics on Clarkdale processors to be outputted through the motherboard's display connectors. It also provides support for technologies like Intel Smart Response Technology, which uses a solid-state drive (SSD) as a cache to improve system performance. While it may not have all the bells and whistles of higher-end chipsets, the H55 was a solid choice for everyday computing and gaming.

Memory

Moving on to memory, the GA-H55M-UD2H comes with four DDR3 DIMM slots. These slots support up to 16GB of system memory, which was quite respectable for its time. The motherboard supports dual-channel memory architecture, which means that memory is accessed in two channels simultaneously, improving memory bandwidth and overall system performance. It supports DDR3 memory modules with speeds of up to 2200MHz (when overclocked), allowing you to take advantage of faster memory modules for improved performance in memory-intensive tasks. Keep in mind that the actual memory speed you can achieve will depend on the capabilities of your CPU and memory modules.

Graphics Output

For graphics, the GA-H55M-UD2H offers a range of connectivity options. It comes with HDMI, DVI-D, and D-Sub (VGA) ports, allowing you to connect to a variety of displays. The inclusion of HDMI and DVI-D ports means you can connect to modern monitors with digital interfaces, while the D-Sub port ensures compatibility with older displays. If you're using a Clarkdale processor with integrated graphics, you can use these ports to output video directly from the motherboard. Alternatively, if you have a dedicated graphics card, you can use the PCI Express x16 slot to connect it and bypass the integrated graphics altogether.

Expansion Slots

Speaking of expansion slots, the GA-H55M-UD2H comes with a single PCI Express x16 slot, which is used for connecting a dedicated graphics card. It also has two PCI Express x1 slots and one PCI slot, which can be used for adding other expansion cards like sound cards, network cards, or storage controllers. The PCI Express x16 slot supports the PCI Express 2.0 standard, which provides ample bandwidth for most graphics cards. While it only has one PCI Express x16 slot, it should be sufficient for most users who are only planning on using a single graphics card.

Storage

In terms of storage, the GA-H55M-UD2H comes with six SATA 3Gb/s connectors. These connectors allow you to connect hard drives, solid-state drives, and optical drives to the system. The SATA 3Gb/s standard provides a decent amount of bandwidth for most storage devices, although it's worth noting that it's slower than the newer SATA 6Gb/s standard. The motherboard also supports RAID configurations, allowing you to set up multiple drives in a RAID array for improved performance or data redundancy.

Audio and LAN

For audio, the GA-H55M-UD2H uses the Realtek ALC889 codec. This is a high-definition audio codec that provides excellent sound quality for both gaming and multimedia applications. It supports 7.1-channel audio output, allowing you to connect a surround sound system for an immersive audio experience. For networking, the motherboard uses the Realtek RTL8111D chip. This is a Gigabit Ethernet controller that provides fast and reliable network connectivity. It supports speeds of 10/100/1000 Mbit, ensuring that you can take full advantage of high-speed internet connections.

Performance and Overclocking

When we talk about the Gigabyte GA-H55M-UD2H, discussing its performance and overclocking capabilities is a must. After all, many enthusiasts of that era were keen on pushing their hardware to the limit. So, how did this motherboard fare?
