Pegatron IPMMB-FM (Formosa) is an OEM motherboard primarily found in HP ENVY Phoenix (e.g., h9 series) and HP ENVY h8
desktop systems. Because it is a proprietary OEM part, a traditional "retail" manual does not exist Key Specifications Overview CPU Support:
LGA 1155 socket; supports Intel 2nd and 3rd Generation (Ivy Bridge) Core i3/i5/i7 processors, specifically optimized for the 4 slots supporting up to (PC3-10600/12800)
. Note that some BIOS versions may cap speeds at 1333MHz even if 1600MHz RAM is installed Expansion: 1 x PCIe x16 (Gen 3.0), 3 x PCIe x1, and 1 x Mini-PCIe Review & User Experience Performance & Upgradability: ipmmb-fm motherboard manual
For its time (circa 2012–2014), the Formosa was a high-end OEM board. It is widely praised for its longevity—many users still run it with modern mid-range GPUs like the GTX 750 Ti . However, newer cards (like the RTX 2060) may require a BIOS update (to version 8.x) to support UEFI booting The "OEM Headache": IPMMB-FM F_Panel connectors from a HP ENVY H8-1455
Comprehensive Guide to the IPMMB-FM (Formosa) Motherboard The IPMMB-FM, commonly known by its HP internal code name "Formosa," is a high-performance Pegatron manufactured motherboard. Designed primarily for HP Phoenix H9 and Envy series desktops, this board uses the Intel Z75 chipset and the LGA 1155 socket, making it a versatile choice for users running Sandy Bridge or Ivy Bridge Intel processors.
While a single official PDF "manual" can be difficult to find since it is an OEM component, this guide serves as a technical manual by consolidating essential specifications, pinouts, and upgrade capabilities.
