  • Capacity1GB
  • SpeedDDR2 800 (PC2 6400)
  • CAS LatencyCL5
  • Voltage1.80V
  • ECCNo
  • Buffered/RegisteredUnbuffered
  • Boosts older desktop responsiveness with 1GB DDR2 800 capacity
  • Delivers stable operation at standard 1.80V voltage
  • Keeps latency low with CAS latency CL5 timing
  • Meets PC2 6400 bandwidth specification for compatible boards

1GB DDR2 800 Desktop Module

This Patriot Memory PSD21G8002 module provides 1GB of DDR2 800 desktop memory. It runs at PC2 6400 speed with a CAS latency of CL5 and a voltage of 1.80V. The unbuffered, non-ECC design fits standard desktop DIMM slots without a heat spreader. It is a straightforward upgrade for older compatible systems.

Suits legacy DDR2 upgrades

This module suits users upgrading or repairing a desktop that specifically requires DDR2 800 memory. It is not for builders who need higher capacities, lower latencies, or platforms that use a different memory generation. Systems limited to slower DDR2 speeds or those requiring registered or ECC modules should look at other options.

PC2 6400 speed rating

The PC2 6400 designation confirms the 800 MT/s data rate that the motherboard must support. Matching this speed rating is the single specification that decides whether this module will operate correctly in the target system.

Points forts

  • Delivers stable operation at standard 1.80V voltage
  • Keeps latency low with CAS latency CL5 timing
  • Meets PC2 6400 bandwidth specification for compatible boards
  • RoHS compliant build reduces hazardous substances

Questions sur cet article

Will this DDR2 800 module fit a motherboard that only accepts DDR2 memory?

Yes, it is a DDR2 800 (PC2 6400) unbuffered DIMM, so it fits any desktop board with DDR2 slots that support 800 MHz operation.

Does the CL5 latency at 1.80 V match the standard JEDEC profile for DDR2 800?

CL5 at 1.80 V is the standard JEDEC timing for DDR2 800, so the module will run at its rated speed without manual BIOS changes.

Can I add this 1 GB stick alongside an existing 1 GB DDR2 800 module for dual-channel operation?

Yes, pairing two identical 1 GB DDR2 800 CL5 modules will enable dual-channel mode on a board that supports it.
