HP FXM1 (E93839) Motherboard Specs 2021: A Complete Breakdown

Published: Retrospective Review (Updated 2021 Data)

If you have landed on this page, you are likely troubleshooting, upgrading, or identifying a motherboard from a late-2010s Hewlett-Packard desktop. The part numbers HP FXM1 and E93839 are frequently searched together, often causing confusion regarding their exact specifications.

First, a critical clarification: The FXM1 and the E93839 are physically the same motherboard. The "E93839" is the spare part number (SPN) or PCB assembly number, while "FXM1" is the system board model identifier. As of 2021, this board is considered legacy hardware (circa 2014-2016), but it remains widely available on the secondary market for repairs.

Below is the definitive specification sheet for the HP FXM1 (E93839) motherboard as understood through the lens of 2021 compatibility.

HP FXN1 E93839 Go to product viewer dialog for this item. is a proprietary motherboard primarily designed for business-class desktop systems such as the HP Compaq 8200 Elite SFF. In 2021, it remained a common component in the secondary market for budget-conscious users looking to maintain or lightly upgrade legacy office hardware. Because "E93839" is a regulatory number used across several generations of HP boards, specifications can vary depending on the specific system it was pulled from. Core Technical Specifications

The most widely documented version of this board, found in the 8200 Elite series, features the following:

Socket and CPU: It typically utilizes the LGA 1155 socket. It is compatible with 2nd generation Intel "Sandy Bridge" processors, such as the Intel Core i5-2400 or i7-2600.

Memory: The board includes four DIMM slots supporting DDR3 SDRAM. hp fxn1 e93839 motherboard specs 2021

Expansion: It usually provides a PCIe 2.0 x16 slot for discrete graphics, though upgrades are often limited by the Small Form Factor (SFF) chassis and low-wattage power supplies typical of these units.

Form Factor: This is a proprietary "modified" ATX or SFF design. It does not follow standard ATX mounting or power connector patterns, making it difficult to use in non-HP cases without significant modification. Variants and Discrepancies

There are later iterations listed under the same "E93839" label that support newer hardware, which can cause confusion:

DDR4 Version: Some listings for HP G3 models indicate an E93839 FXN1 variant that supports Intel 6th Gen (Skylake) CPUs like the i5-6500 and uses DDR4 memory.

I/O Ports: Standard ports across most versions include DisplayPort, VGA, USB 2.0, and Ethernet (RJ-45). 2021 Context and Usage

By 2021, these motherboards were largely relegated to "e-sport" starter builds or home office refurbishments. Users often paired them with low-profile GPUs like the GT 1030 or GTX 1050 Ti to create functional, entry-level gaming machines from discarded corporate hardware.

HP E93839 (FXN1) motherboard — 2021-style review

Summary

OEM HP ATX (proprietary) motherboard used in HP Compaq/Elite series (8200/8300/Pro/EliteDesk families). Typical revision: FXN1 / Rev. A (model E93839 / SP/PN variants).
Target: business desktops; not a consumer/gaming board. Strengths: reliability, compact integration, decent I/O for office use. Limitations: proprietary layout, older LGA1155 platform, limited upgrade path.

Key specifications (common across listings)

CPU socket: LGA 1155 (Intel 2nd/3rd‑gen Core / Xeon compatible depending on BIOS). Chipset commonly reported: Intel Q67 (desktop variants) or chipset family used in HP 8200/8300 series.
Memory: 4 × DDR3 UDIMM slots, dual‑channel (PC3‑10600 / DDR3‑1333 typical). Max RAM depends on HP BIOS—commonly 16–32 GB practical.
Expansion: 1× PCIe x16 (proprietary / full‑length), additional PCI/PCIe slots vary by revision/case (SFF vs ATX).
Storage: Multiple SATA ports (SATA II common), some OEM boards include eSATA on rear I/O.
Rear I/O: VGA, DisplayPort, DVI/HDMI (varies by model), multiple USB 2.0/3.0 ports, RJ‑45 LAN, audio jacks, PS/2 on some SKUs.
Onboard features: integrated audio, integrated Intel LAN, integrated GPU support via CPU graphics, TPM on some revisions.
Form factor: HP proprietary ATX-like layout (not guaranteed to fit all standard chassis without mounting differences).
Power connector: standard 24‑pin ATX + supplemental 4/8‑pin CPU power on many variants; SFF variants use proprietary power connectors.
Typical BIOS: OEM HP AMI/UEFI with limited user tuning and restricted CPU support lists.

Performance and compatibility

Performance reflects installed CPU (LGA1155). Common pairings in listings: Core i5‑6500 mentioned (note: i5‑6500 is LGA1151 — some listings mislabel CPUs; true compatible CPUs are 2nd/3rd gen LGA1155 like i5‑2500/i7‑3770). Verify CPU socket/chipset match before buying.
Good for office productivity, light multimedia, and legacy business tasks. Not suitable for modern high‑end gaming or heavy content creation.
BIOS and chipset limit support for newer CPUs, NVMe is unsupported natively (though NVMe via PCIe adapter may work in some revisions).

Build, reliability, and serviceability

Built for enterprise deployment: conservative power delivery, integrated cooling brackets, and long production runs.
HP OEM parts may vary (multiple SP/PN numbers seen). Used/refurbished market common; check seller photos, revision labels (FXN1, Rev A, SP/611796‑002 / 611835‑001 etc.).
Repairable but connectors and front‑panel pinouts may be proprietary—replacement in a non‑HP case can be fiddly.

Pros

Reliable OEM hardware for business desktops.
Adequate I/O and memory capacity for office workloads.
Readily available on secondary market as replacements or parts.

Cons

Aging LGA1155 / DDR3 platform with constrained upgrade path.
Proprietary layout/power connectors in some SKUs limit reuse in custom builds.
Limited BIOS tuning and feature set vs retail motherboards.
Watch for incorrect listings (misstated CPU/socket).

Buying advice (2021 / used‑market perspective)

Verify exact revision (FXN1 / Rev A) and confirm socket/chipset with seller photos and HP part numbers.
Confirm which HP model the board came from (8200/8300/EliteDesk) to match case and power connectors.
For a replacement in an HP machine, this board is a practical choice; for a custom build, prefer a standard ATX retail board for easier upgrades.
Expect typical used prices (varied by condition): low for defective/parts boards; mid range for tested working boards with shipping.

Verdict A solid OEM motherboard for maintaining older HP business desktops—dependable for office use and repairs, but obsolete for modern performance or upgrade flexibility. Buy as a replacement/repair part; avoid as the foundation for a new long‑term custom build.

If you want, I can:

extract exact specs from a specific HP part number you found, or
compare this board to a modern inexpensive ATX board for reuse in a custom build. Which would you prefer?

Note: This board is often mis-typed as "FXN1." The correct model number from HP’s internal markings is FXM1, with the PCB part number E93839.

2. Memory (RAM)

This is a critical spec for users looking to upgrade. The E93839 board utilizes DDR4 SO-DIMM slots (laptop-style memory) to maintain its compact size.

Type: DDR4-2666 SODIMM (Non-ECC).
Slots: 2 Slots.
Maximum Capacity: 64 GB (2 x 32 GB).
2021 Standard: Most units shipped in 2021 came standard with 8GB or 16GB, but the board handles dual-channel memory efficiently, making it a strong candidate for RAM upgrades to boost performance.
