Dell OptiPlex GX620 SFF motherboard

This Dell KH290 system board fits the OptiPlex GX620 small-form-factor chassis and uses the LGA 775 socket for Pentium 4, Pentium D or Celeron processors. It includes the Graphics Media Accelerator 950 for onboard video and provides four memory slots supporting up to 4 GB total. Dual Intel LAN chipsets give two wired network connections on a single board.

Replacement board for failed GX620 SFF units

The board is a direct swap for a damaged original in the same OptiPlex GX620 SFF enclosure. It restores the system to its factory specification without requiring a new case, power supply or operating system licence. The upgrade is worthwhile when the existing board has failed and the owner wants to keep the current hardware configuration intact.

LGA 775 platform limits memory to 4 GB

The four DIMM slots top out at 4 GB, which restricts multitasking and modern operating-system performance. A single PCI Express x16 slot exists, but the small-form-factor chassis limits card length and height, so only low-profile graphics cards will fit. Onboard Graphics Media Accelerator 950 output is limited to legacy display interfaces.

Preguntas sobre este artículo

Will the KH290 board fit my OptiPlex GX620 SFF case?

The board uses the SFF form factor built for the OptiPlex GX620 chassis, so the mounting holes and I/O shield line up with that case.

What is the tricky step when installing this LGA 775 board?

Align the processor notches before lowering the socket lever; forcing the lever with a misaligned CPU bends the delicate socket pins.

How much memory can I upgrade to later on the KH290?

Four DIMM slots accept up to 4 GB total, so the maximum upgrade is 4 GB across all slots.
