Two green DDR2 memory modules with silver heat spreaders

Kingston Technology Corp.

Kingston Technology Corp. KTH-XW667/1G 1GB (2 x 512MB) DDR2 667 ECC Fully Buffered memory upgrade

SKU CH-F0EW-BPVPZ MPN KTH-XW667/1G

A 1GB dual-channel DDR2 667 kit with ECC fully buffered modules and heat spreaders for HP/Compaq systems

  • Total capacity1 GB (2 × 512 MB)
  • Rated speedDDR2 667 (PC2 5300)
  • CAS latencyCL5
  • Rated voltage1.8 V
  • Buffer typeFully Buffered
  • Product type240-Pin DDR2 SDRAM
  • Dual-channel kit doubles bandwidth with matched 512MB modules

  • 80 V operation reduces power draw and heat
  • Heat spreader included keeps modules cool under load

HP/Compaq DDR2 upgrade kit

This 1GB kit contains two 512MB modules designed for HP and Compaq systems that require 240-pin DDR2 667 memory. The fully buffered architecture with ECC provides the error correction and signal integrity needed by compatible workstations and servers.

CL5 latency at 1.80V

Rated DDR2 667 (PC2 5300) with CAS latency CL5, the modules operate at the standard 1.80 volt DDR2 voltage. A heat spreader on each DIMM helps dissipate heat during typical workloads without requiring active cooling.

Sustained ECC workloads

Under continuous operation the fully buffered design maintains signal quality across the memory bus while ECC corrects single-bit errors in real time. Systems needing larger capacities or unbuffered memory will not support this kit.

Questions about this item

How do I install the 240-pin DDR2 modules and which slot order ensures dual-channel operation?

Power down the HP/Compaq workstation, open the chassis, and press each 240-pin module firmly into the paired DIMM slots until the retention clips click; the two 512MB sticks must occupy the matched channel slots for dual-channel mode.

Will the heat spreader or ECC circuitry require any periodic maintenance or replacement?

The integrated heat spreader and ECC logic are solid-state with no moving parts; no scheduled cleaning, re-pasting, or component replacement is needed for the life of the modules.

At what point does the CL5 latency at 1.80V become the bottleneck during sustained workloads?

Under continuous heavy memory traffic the fixed CL5 timing at 1.80V limits throughput before thermal throttling or voltage headroom become factors.
