Micron 240-pin DDR2-667 UDIMM module

This Micron Technology, Inc. switch module is a 240-pin UDIMM operating at DDR2-667 with a PC2-5300 rating. It uses a 128 x 8 organisation, 2Rx8 configuration and runs at 1.8 V. The part is supplied new and matches the manufacturer highlight specification exactly.

Suitable for legacy systems needing DDR2 memory

This module suits technicians servicing older networking gear or workstations that require 240-pin DDR2-667 UDIMMs with a CL5 latency. It is not for systems that only accept newer memory types or different pin counts.

Questions about this item

Will the 240-pin DDR2-667 UDIMM need any firmware updates or capacitor replacements over time?

No firmware or capacitor maintenance is required; the module is a passive DDR2 DRAM stick that operates at 1.8 V with CL5 timing.

What thermal or electrical limit appears first when the 2Rx8 module runs continuously at 667 MHz?

The 1.8 V supply rail and CL5 latency define the electrical envelope; sustained operation stays within the DDR2-667 specification without a separate thermal throttle.
