Hp Fxn1 E93839 Motherboard Specs 2021 ((top)) «TRUSTED – HACKS»

The HP FXN1 E93839 (often labeled as the E93839) is a proprietary OEM motherboard primarily designed for HP's business-class desktops and workstations. In 2021, this board remained a popular choice for budget-conscious users looking to refurbish or upgrade systems like the HP EliteDesk 800 G2 or G3 series. Core Technical Specifications

The E93839 FXN1 is typically built on a modified ATX or SFF (Small Form Factor) design, depending on the specific chassis it was pulled from.

Socket & Chipset: It features the LGA 1151 socket, which supports 6th, 7th, and sometimes 8th generation Intel Core processors (Skylake and Kaby Lake architectures). Some earlier variations using the E93839 designation may feature the LGA 1155 or LGA 1150 sockets for older 2nd to 4th generation CPUs.

Memory Support: Most 2021-relevant versions support DDR4 SDRAM across four slots, allowing for a maximum of 64GB (4 x 16GB) with speeds typically up to 2400MHz. Expansion Slots:

1 x PCIe 3.0 x16: Primary slot for dedicated graphics cards. Multiple PCIe x1: For networking or sound cards.

M.2 Slots: Many versions include an M.2 socket for NVMe SSDs and a separate M.2 socket for WLAN/Bluetooth modules. Ports and Connectivity

The board is engineered for professional environments, offering a robust array of I/O options:

Video Output: Dual DisplayPort and often a VGA or HDMI port for multi-monitor setups. hp fxn1 e93839 motherboard specs 2021

USB Support: Includes a mix of USB 3.0 (SuperSpeed) and USB 2.0 ports; some G3 models even feature a USB-C port.

Storage: At least two to four SATA III (6Gb/s) connectors for internal HDDs and SSDs.

Networking: Integrated Intel I219-LM Gigabit Ethernet for reliable wired connections. Compatibility and Limitations

While the FXN1 E93839 is a versatile board, its proprietary nature introduces specific constraints: HP Desktop PCs - Motherboard Specifications, Row

Product Review: HP FXN1 (E93839) Motherboard

Verdict: The HP FXN1 is a reliable, OEM-specific motherboard designed for the HP ProDesk 600 G7 Desktop Mini (DM). It offers excellent 10th Gen Intel performance in a tiny footprint, but it suffers from the typical limitations of proprietary boards: non-standard power connectors and limited expansion slots.

9. BIOS and Firmware (2021 Status)

• BIOS Type: AMI UEFI (with HP Corporate GUI)
• BIOS Lock: Yes (Modern HP boards lock the "Intel ME" region; you cannot flash retail BIOS)
• Latest Version as of 2021: v2.37 (Rev. A – Released Dec 2020)
  • Fixes: Spectre/Meltdown microcode patches, Windows 10 20H2 stability.
  • Removal: You cannot downgrade past v2.30 due to Intel BootGuard.

2. Performance Analysis

CPU & Chipset: The FXN1 utilizes the Intel Q470 chipset, which is a step up from the consumer-grade B460 boards. The Q470 chipset supports Intel vPro technology, making this board ideal for corporate IT environments where remote management and security are priorities.

• Socket LGA 1200: This board supports the Comet Lake-S series. In 2021 configurations, this typically shipped with CPUs ranging from the Core i5-10500 up to the i7-10700.
• Thermal Constraints: Because this is a "Desktop Mini" board, there are no VRM heatsinks. It relies on the chassis blower fan for cooling. While it handles standard TDPs (35W-65W) well, it is not designed for sustained turbo boosts on high-end i9 chips without aggressive fan curves.

Memory: It uses SO-DIMM slots (laptop-style RAM) rather than standard DIMMs. This saves space but limits you to standard JEDEC speeds. While the board can handle 3200MHz RAM, it will often downclock to 2666MHz or 2933MHz depending on the specific CPU installed (i5 vs i7).

Storage: The board is modern in its approach, featuring a primary M.2 NVMe slot. It lacks native SATA data ports on the board itself, meaning traditional 2.5" SSDs or HDDs require a specific HP drive cage and cable kit that connects to the motherboard's SATA header (if populated) or USB header.

Storage Bottlenecks

• The SATA 3.0 port is fine for a SATA SSD (480GB–1TB).
• No M.2 slot – cannot use NVMe drives (a major limitation by 2021 standards).

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?

5. How to Identify Your Exact Version

1. Look for E93839-xxx on the PCB. The suffix matters:
   • -001 = H81 chipset, supports i7-4790S
   • -002 = H61 chipset, max i7-3770S (Ivy Bridge, not Haswell)
2. Check BIOS version at boot (F10) – version 8.21 or later is required for 16GB RAM support.
