Two green low-profile DDR2 modules with gold contacts

Kingston Technology Corp.

Kingston Technology Corp. KTD-DM8400B/2G 4GB (2x2GB) DDR2-667MHz PC2-5300 240-Pin 1.8V Low Profile Desktop RAM

SKU CH-3KBY-FHKJ2

A 4 GB DDR2 desktop memory kit running at 667 MHz with low-profile 240-pin modules at 1.8 V

  • Capacity4GB (2 x 2GB)
  • 4 GB total capacity from two 2 GB modules
  • DDR2-667 MHz speed rated at PC2-5300
  • Low-profile 1.8 V design fits compact desktop cases
  • 240-pin DIMM format for standard desktop motherboards
  • CL5 latency for responsive system performance

Kit Contents

This Kingston kit supplies 4 GB of DDR2 desktop memory in two matched 2 GB modules. It is intended for owners of older systems that still use 240-pin DDR2 slots and want a simple capacity refresh.

Interface Limits

The modules run at the DDR2-667 data rate, also labelled PC2-5300, so peak bandwidth is capped by that standard. Motherboards limited to slower DDR2 speeds will clock the kit down automatically, while boards without DDR2 slots cannot accept it at all.

Form Factor Fit

Each stick uses the low-profile 240-pin DIMM outline and operates at 1.8 V. Builders whose cases or CPU coolers leave minimal vertical clearance will find the reduced height essential, while standard-height slots will also accept the modules without issue.

商品問答

Should I pick the 4GB kit or a different capacity?

The kit provides 4GB total in two 2GB modules; choose it if your motherboard supports DDR2 and has two free 240-pin slots.

What does the 667MHz rating deliver in my desktop?

Running at 667MHz DDR2, the modules operate at the PC2-5300 data rate for standard desktop workloads on compatible boards.

How does the 240-pin DDR2 interface limit performance?

The 240-pin DDR2 connection caps transfer speed at the 667MHz bus, so the system cannot exceed the PC2-5300 rate regardless of other components.
