Green 172-pin MicroDIMM DDR2 module, 47mm by 32mm, eight BGA chips on both sides

Simmtec, Inc

Simmtec, Inc 1GB DDR2 533MHz PC2-4200 172-pin MicroDIMM desktop RAM

SKU CH-Q1S7-7B8MV

A 1 GB DDR2 module running at 533 MHz in a 172-pin MicroDIMM form factor measuring 47 mm by 32 mm, operating at 1.8 V with an unbuffered, non-ECC design and double-sided BGA chips

  • Total capacity1 GB
  • 1GB capacity upgrades DDR2 systems
  • 533MHz speed matches PC2-4200 standard
  • 8V operation reduces power draw
  • 172-pin MicroDIMM fits compact boards
  • Unbuffered non-ECC design for desktop use

Simmtec 1GB DDR2 MicroDIMM

This Simmtec module delivers 1 GB of DDR2 memory at 533 MHz through a 172-pin MicroDIMM interface. It suits owners of legacy compact desktops or embedded boards that require the 47 mm by 32 mm form factor and 1.8 V operation. The JEDEC-standard PC2-4200 rating ensures baseline compatibility with platforms designed for this speed grade.

Sustained load behaviour

The unbuffered, non-ECC design with eight BGA chips split across both sides of the PCB provides standard desktop-grade throughput for continuous workloads. Without error-correction circuitry the module relies on the memory controller for data integrity during extended sessions. The fixed 1.8 V supply voltage keeps power draw predictable under prolonged use.

Upgrade context

This part replaces a failed or lower-capacity MicroDIMM in systems that accept only the 172-pin, 47 mm by 32 mm layout. The jump is worthwhile when the platform supports PC2-4200 speeds and the application benefits from a full 1 GB rank. It does not fit standard DIMM slots or SODIMM sockets, so buyers needing those formats must look elsewhere.

Questions about this item

How much power does the 1.8 V DDR2 module draw when running continuously?

The module operates at a standard 1.8 V supply voltage typical for DDR2 memory. Actual power draw depends on the motherboard's memory controller and system load.

What motherboard slot is required for this 172-pin MicroDIMM?

This stick uses a 172-pin MicroDIMM connector measuring 47 mm by 32 mm. It only fits motherboards with a matching MicroDIMM socket, not standard DIMM or SO-DIMM slots.

Will the 533 MHz speed work if my board only supports slower DDR2?

The module is rated for PC2-4200 at 533 MHz. DDR2 memory typically downclocks to match the motherboard's maximum supported speed.
