Introduction

We analyzed the Gigabyte H81M-S2PH, a value socket LGA1150 motherboard based on the Intel H81 chipset. It has only two memory sockets, one PCI Express x16 slot, two USB 3.0 ports, two SATA-600 ports, and supports legacy serial and parallel ports.

The Intel H81 is still the most basic chipset for fourth-generation Core i CPUs from Intel. The main differences between this entry-level chip and the high-end model of its generation, the Z87, are the lower number of SATA-600 ports and USB 3.0 ports (two versus six of each), the absence of RAID and SRT (Smart Response Technology) support, and the support for only one PCI Express 3.0 x16 slot. There is no support (at least officially) for changing the clock multiplier on “K” unlocked CPUs, which makes it a bad choice for overclocking.

You can see the Gigabyte H81M-S2PH motherboard in Figure 1. It uses the micro ATX form factor, measuring 9.6” x 7.1” (244 mm x 180 mm).
