Hp Fxn1 E93839 Motherboard Specs 99%

HP FXN1 E93839 motherboard (often identified by part numbers 611834-001 611794-000 ) is a proprietary system board primarily found in the HP Compaq 8200 Elite

series. It is designed for business-class reliability in small form factor (SFF) and desktop environments. Core Specifications Form Factor : Custom uATX / SFF (Small Form Factor). : Intel Q67 Express. : LGA 1155 (Socket H2). CPU Support

: 2nd Generation Intel Core i3, i5, and i7 processors (Sandy Bridge).

Note: Later revisions labeled "E93839" may support newer sockets (e.g., LGA 1150 or 1151), so check your specific socket carefully. Memory & Expansion HP motherboard E93839 FXN1 With Intel I5-6500 - eBay hp fxn1 e93839 motherboard specs

Variant B: Intel Apollo Lake (rare)

BGA 1296 – soldered
Common CPU: Intel Celeron J4005/N4000 (2C/2T, 1.1–2.6 GHz, UHD 600)
Not Core i3/i5/i7 – do not attempt to swap.

No upgrade possible – the CPU is soldered directly to the board.

4. Storage Options

| Interface | Details | |-----------|---------| | SATA 3.0 | 1 x 2.5” drive bay (7mm or 9.5mm height). Uses a proprietary combo power/data ribbon cable. | | M.2 slot | Key M. Supports SATA SSD (B+M key) or NVMe PCIe 2.0 x2/x4 (depends on BIOS). Many boards only do SATA on M.2. | | M.2 length | 2280 (full length) | | Boot order | Can boot from SATA or M.2. BIOS may limit NVMe boot on earlier revisions. |

Recommendation: Replace HDD with SATA SSD for best performance. M.2 NVMe may not be recognized – test before buying. HP FXN1 E93839 motherboard (often identified by part

9. Common Upgrades & Compatibility

| Part | Recommendation | |------|----------------| | RAM | DDR4-2666 SO-DIMM 1.2V (Samsung, Hynix, Crucial) | | SATA SSD | Any 2.5” 7mm SATA SSD (e.g., WD Blue, Crucial MX500) | | M.2 SSD | Use SATA M.2 (e.g., WD Green M.2) – avoid NVMe unless confirmed | | Wi-Fi | M.2 2230 (Key E) – Intel 7265 or 9260 (AC), not CNVi | | Thermal paste | Non-conductive (Arctic MX-4, Noctua NT-H1) |

4. RAM Specifications & Upgrade Path

The HP FXN1 E93839 is picky about RAM. It only has two DIMM slots, so you cannot run four sticks of RAM.

Maximum Capacity: 16GB (2 x 8GB modules).
Type: DDR3, 1.5V (low-voltage 1.35V DDR3L may work but is not officially supported in all BIOS versions).
Speed: 1600MHz modules will work but may be downclocked to 1333MHz if you install a CPU with a slower memory controller (e.g., an i3 or Pentium).
Dual Channel: For best performance, install matched pairs (same capacity, same speed, same brand).

What to Avoid:

ECC (Error Correcting Code) RAM – not supported.
DDR2 or DDR4 – physically incompatible.
Mixing RAM sizes (e.g., 4GB + 8GB) – forces single-channel mode, reducing memory bandwidth by up to 50%.

Recommended Upgrade: Corsair Vengeance or Kingston HyperX DDR3 1600MHz (2x8GB kit).

9. BIOS and Firmware Limitations

The HP BIOS (accessible by pressing F10 during boot) is locked down compared to retail boards.

No Overclocking: You cannot adjust CPU multiplier, BCLK, or memory timings.
Limited TDP Support: The VRMs (voltage regulator modules) are bare. Installing a 95W TDP CPU like the i7-4790 is the max; do not attempt an i7-4790K (88W TDP is fine, but the K feature is wasted).
Secure Boot & UEFI: Supports Windows 10 and 11 (with TPM 2.0 workarounds, though this board lacks a physical TPM module; it uses firmware TPM).
BIOS Updates: Download from HP’s support site using your specific Pavilion serial number. A BIOS update is required for Haswell Refresh CPUs (i7-4790, i5-4690) to be recognized.

10. Common Issues and Troubleshooting

Problem: PC turns on but no display.
- Fix: Reseat RAM. Clear CMOS (remove coin cell battery for 1 minute). Ensure the monitor is plugged into the correct video output (if you have a GPU, don’t use motherboard outputs).
Problem: Computer randomly shuts down or freezes.
- Fix: Usually a failing capacitor or overheating VRM. Clean dust from heatsinks. Replace thermal paste on CPU. More often, the original power supply is failing (they are known to degrade).
Problem: "Boot Device Not Found" after installing new SSD.
- Fix: Go into BIOS (F10) → Storage → Boot Order. Ensure SATA controller is set to AHCI (not RAID). Disable "Secure Boot" temporarily.
