is a highly reliable silicon layout built to handle heavy office workloads without thermal throttling:

Note: The "E93839" code is actually a UL regulatory marking often found on many Dell boards (manufactured by Foxconn), so precise identification usually depends on the Dell Part Number (P/N), such as C27VV or 200DY. Core Specifications CPU Socket: LGA 775 (Socket T). Intel Q45 Express with ICH10DO. Processor Support: Intel Core 2 Quad (up to 1333 MHz FSB). Intel Core 2 Duo Intel Pentium Dual-Core DDR3 SDRAM (non-ECC only). 4 DIMM slots. Max Capacity: Officially dell e93839 ga0402 motherboard specs upd

While the "E93839" markings refer to a regulatory component tracking registration used across various Dell, HP, and Foxconn OEM assemblies, the specific combination of pins it down specifically to the workhorse LGA 775 configuration. Core Architecture & Chipset

Optimally paired with high-frequency dual-core chips such as the Core 2 Duo E8400 (3.0 GHz) or E8600 (3.33 GHz).

: Driven by four SATA 3.0 Gbps interfaces, the board easily handles multiple Solid State Drives (SSDs) and traditional Hard Disk Drives (HDDs). Expansion and Connectivity Ports In this comprehensive guide, we break down every

| | Specification | Additional Notes | | :--- | :--- | :--- | | Power Supply | Typically a 255W to 305W PSU, often with proprietary form factor and connectors | Upgrading the PSU is challenging due to Dell's proprietary standards. If you're adding a powerful GPU, you may need an adapter (e.g., 24-pin to Dell 8-pin) or a PSU specifically designed for Dell systems. | | BIOS | Legacy BIOS (Non-UEFI) | - Version A16 is a common final version for Optiplex 760 systems. | | | | - No UEFI support: This means you cannot boot from GPT drives or use modern bootloaders without legacy compatibility mode. | | | | - Settings: You can access the BIOS by pressing F2 during startup. Key settings include boot order, SATA mode (AHCI or IDE), and power management. |
