Four green DDR DIMM modules with gold contacts

Simmtec, Inc

Simmtec, Inc 4GB (4×1GB) DDR DIMM 184-pin 400MHz PC3200 CL2.5

SKU CH-TWGH-WX7BW

Four 1 GB DDR DIMMs running at 400 MHz with CL2.5 timing on 184-pin modules

  • Capacity4GB
  • 4GB total capacity from four matched 1GB modules
  • 400 MHz DDR speed rated as PC3200
  • CL2.5 latency for responsive data access
  • 184-pin DIMM form factor fits standard desktop slots
  • Low-density chips tested before shipment for reliable operation

4GB DDR DIMM Kit for Legacy Desktops

This kit provides 4 GB of DDR memory arranged as four 1 GB modules. Each module uses a 184-pin DIMM form factor and runs at 400 MHz with a PC3200 rating. It is suited to older desktop systems that accept this specific DDR generation.

Suits Restorations Needing Low-Density CL2.5 Modules

The kit targets builders repairing or upgrading boards that require low-density DDR DIMMs with a CL2.5 latency. Systems needing a different module density, alternative pin count, higher capacity per stick, or a faster speed grade will not be compatible with this package.

184-Pin DDR 400 PC3200 CL2.5 Specification

The decisive specification is the 184-pin DDR interface operating at 400 MHz with PC3200 bandwidth and CL2.5 timing. Matching these exact parameters to the motherboard documentation determines whether this kit will function in the target machine.

Questions about this item

What does PC3200 400 MHz mean for real-world bandwidth?

The modules run at 400 MHz DDR, which is the PC3200 rating; actual throughput depends on the motherboard chipset and memory controller.

Will these 184-pin DIMMs fit my motherboard slots?

They require standard 184-pin DDR DIMM slots; low-density 1 GB modules are keyed the same as high-density but some early chipsets only recognise the latter.

What is the correct installation order for the four sticks?

Populate the primary channel pair first — usually the two slots of the same colour — then add the remaining pair; skipping the primary pair is the common mistake.
