Targeted DDR3 upgrade for Intel embedded boards

This 2GB DDR3 1066MHz SO-DIMM is built specifically for the Intel D2500Cc, D2500Hn, D2500Hnd and D2550Dc2 motherboards. It uses a 204-pin form factor and operates at 1.5V with CL7 timings. The single-rank, unbuffered design matches the memory architecture those platforms expect.

Steady operation at rated JEDEC speed

The module runs at DDR3 1066 (PC3 8500) with 7-7-7 latency and no heat spreader, relying on the board's airflow for cooling. Non-ECC chips mean error correction is handled by the platform if supported, otherwise data moves without parity overhead. Voltage stays at the standard 1.5V so power draw remains predictable during long workloads.

Direct slot installation with one limitation

Insert the stick into the single SO-DIMM socket until the retention clips click; no tools or configuration are required. The board only accepts one module and caps total memory at 2GB, so this kit fills the only slot available. Buyers who want more capacity cannot expand further on these motherboards.

Questions about this item

How much power does this 1.5V DDR3 1066MHz module draw during continuous operation?

It operates at the standard 1.5V DDR3 voltage. Actual power draw depends on the motherboard's memory controller and system workload.

What motherboard slot and chipset are required to install this 204-pin SO-DIMM?

It fits a 204-pin DDR3 SO-DIMM slot and is validated for Intel D2500Cc, D2500Hn, D2500Hnd and D2550Dc2 motherboards.

Can this CL7 1066MHz stick run alongside an existing module in a D2500 series board with one socket?

The compatible boards listed have a single memory socket, so only one module can be installed at a time.
