For a user working with this board, this specification dictates the upgrade path. If the system currently runs a Pentium or an i3, there is a viable upgrade path to an i5-2400 or i7-3770. However, a common pitfall with the H61 chipset is the lack of native USB 3.0 support in early revisions and limited overclocking capabilities. Therefore, users should not attempt to push "K" series processors (like the i5-2500K) beyond their stock frequencies on this specific board, as the power delivery system on the MIH61R is designed for stability rather than performance tuning.
The is an OEM motherboard manufactured by Foxconn exclusively for Dell. It’s based on the Intel H61 Express chipset and uses the LGA1155 socket, making it compatible with Intel’s 2nd‑generation (Sandy Bridge) and—with certain BIOS modifications—3rd‑generation (Ivy Bridge) processors.
