| | Specification | Additional Notes | | :--- | :--- | :--- | | Motherboard Model | GA0402 / Dell 0C27VV / 0G214D | The primary model number is GA0402 . DP/N C27VV is a specific variant commonly found in the Optiplex 780 Mini Tower. | | Chipset | Intel Q43 Express with ICH10D Southbridge | This chipset provides support for Intel's Core 2 Duo and Core 2 Quad processors. The ICH10D Southbridge handles I/O functions like SATA and USB. | | CPU Support | LGA775 Socket Supports 65W & 95W CPUs (later BIOS may add support for 95W CPUs like the Core 2 Quad Q9650) | Compatible CPUs: | Intel Core 2 Quad (e.g., Q9550, Q9650) – Best for multi-tasking and modern workloads. | Intel Core 2 Duo (e.g., E8400, E8600) – Good for basic tasks and gaming. | Intel Pentium Dual-Core / Celeron | | BIOS must support later CPUs. A16 is a common final BIOS version for related Optiplex 760 systems and should support most LGA775 CPUs. | | Power Delivery: The motherboard's VRM (Voltage Regulator Module) design limits CPU upgrades. Some variants only support 65W CPUs (e.g., E8600), while others can handle 95W CPUs (e.g., Q9650). Check Dell's support documentation for your specific Service Tag (e.g., 8CKX62S). | | RAM | 4 x DIMM slots DDR2 (for most variants) or DDR3 | Variants: | | | DDR2 variants: Max 8GB (2GB per slot), speeds 667/800MHz (non-ECC, 1.8V). | | | DDR3 variants: Max 12GB - 16GB (e.g., 4GB + 4GB + 4GB), speeds 1066/1333MHz. You must use DDR3L (low voltage) or standard DDR3 depending on motherboard specs. | | Storage | 4 x SATA 2.0 (3Gb/s) ports | Supports SATA hard drives and SSDs (solid-state drives). An SSD is the single best upgrade for any older system and will provide a massive performance boost in boot times and application loading. | | Expansion Slots | 1 x PCIe x16 (Gen 2) | - PCIE_X16: Use for dedicated graphics cards (GPU). | | | 1 x PCIe x16 (Gen 2, wired as x4) | - PCIE_X4: Often physically an x16 slot but wired for x4 speeds. Best for non-GPU cards (e.g., NVMe adapters). | | | 1 x PCIe x1 | - PCIE_X1: For network cards, sound cards, or USB expansion cards. | | | 3 x PCI | - PCI: For legacy expansion cards (e.g., older sound cards, TV tuners). | | Back I/O Ports | - 1 x PS/2 Keyboard/Mouse combo | These ports are standard for the era: | | | - 1 x VGA (Integrated) | | | | - 1 x DVI-D (Integrated) | - VGA: For analog monitors. | | | - 4 x USB 2.0 ports | - DVI-D: For digital monitors. | | | - 1 x Gigabit Ethernet (RJ45) | - Ethernet: Realtek or Intel 82567LM (check your board). | | | - 3 x Audio jacks (Line-in, Line-out, Mic) | - Audio: 6-channel HD Audio. | | Internal Connectors | - Front panel header (Power/Reset/LEDs) | - Front Panel Header: Pinout is proprietary. You cannot use a standard ATX case's front panel connector without adapters. | | | - Front USB 2.0 headers (usually 2) | | | | - Front audio header | - USB/Audio Headers: Standard for case front-panel USB and audio ports. | | | - 4-pin CPU fan header | | | | - 3-pin Chassis fan header(s) | - Fan Headers: Often Dell-proprietary pinouts. Standard fans may run at 100% speed. Use fans designed for Dell systems or rewire connectors. | | | - 24-pin Main Power | - Main Power: Standard ATX pinout, but the PSU itself may have proprietary wiring. | | | - 4-pin CPU Power | |
