Socket FM2+ foundation

The ASUS A68HM-K uses the AMD A68H chipset on a Micro ATX board for FM2+ Athlon and A-Series processors up to four cores. Two DDR3 DIMM slots support dual-channel memory up to 32 GB at speeds from 1333 to 2400 MHz overclocked. A single PCIe 3.0 x16 slot, one PCIe 2.0 x1 slot and one legacy PCI slot handle expansion.

Thermals and power basics

The board draws power through standard ATX and 4-pin CPU connectors with no extra power phases listed. Passive heatsinks cover the chipset and voltage regulators; no fan headers beyond the CPU and chassis connectors are detailed. Typical idle power stays low for office workloads while the integrated Radeon graphics share up to 2048 MB of system memory under load.

Build and daily connectivity

Realtek ALC887-VD provides eight-channel audio through three rear jacks. Networking uses a Realtek 8111GR controller for 1 Gbps wired LAN. Rear I/O includes D-Sub, DVI, two PS/2 ports, two USB 2.0 ports, two USB 3.1 Gen 1 ports and the audio jacks. Four SATA 6 Gb/s ports support RAID 0, 1, 10 and JBOD for storage flexibility.

Questions about this item

How do I install the CPU into the FM2+ socket without bending pins?

Lift the socket lever, align the gold triangle on the processor with the socket corner, place the chip gently without force, then lower and lock the lever; the step people miss is forgetting to remove the protective plastic cover from the socket before insertion.

What maintenance will the Realtek ALC887 audio and Realtek 8111GR LAN require over time?

No scheduled maintenance is needed for the audio or LAN controllers; keep the rear I/O ports dust-free and update drivers from the ASUS support page when a new Windows build is installed.

Which limit appears first when running the DDR3 2400 O.C. memory continuously at full load?

The memory controller on the A-Series APU typically hits its thermal ceiling before the board's 32 GB capacity or the dual-channel bandwidth is saturated, so sustained speeds may drop to 2133 or 1866 MHz under heavy load.
