  • 1GB desktop DDR2 module for legacy system upgrades
  • CL4 latency supports responsive operation at rated speed
  • PC4200 (533 MT/s) rating matches DDR2-533 motherboard specs
  • Unbuffered 240-pin DIMM fits standard desktop slots

Kingston 1GB DDR2 Desktop Module

This Kingston Technology Corp. desktop memory module provides 1GB of DDR2 capacity for older systems. It operates at PC4200 (533) speed with a CAS Latency of CL4 and runs on 1.8V. The unbuffered DIMM uses a 240-pin interface and a 2RX8 chip organisation. It is supplied in new condition.

Suits legacy DDR2 upgrades; not for modern builds

This module suits owners of desktop motherboards that accept DDR2 PC4200 memory and need a 1GB stick to maintain or repair an existing system. It will not help builders who want higher capacities, faster speeds, ECC error correction, or laptop SO-DIMM form factors. Systems requiring buffered or registered memory should look elsewhere.

Key spec: DDR2 PC4200 at CL4

The single specification that decides fitment is the DDR2 PC4200 (533) rating combined with CL4 latency at 1.8V. Your motherboard must explicitly support this exact speed grade and voltage for the module to function correctly. Verify the required part number against your board manual before purchase.

Questions about this item

Will my motherboard accept a 240-pin DDR2 DIMM running at 1.8 V?

This module uses the standard 240-pin DDR2 form factor and operates at 1.8 V, so any desktop board with DDR2 slots that support 1.8 V will accept it.

Can I run this CL4 PC2-4200 stick alongside slower CL5 DDR2 modules I already have?

Yes, the memory controller will down-clock all modules to the slowest speed and highest latency present, so CL5 sticks will force this CL4 kit to run at CL5 timings.

How can I confirm the module is detected at 533 MT/s with CL4 timings after installation?

Enter the BIOS or use a tool such as CPU-Z; the SPD tab should show PC2-4200, 533 MT/s and CL4-4-4-12 for this 1 GB DIMM.
