Single green 288-pin DDR4 LRDIMM module with black memory chips and gold contacts

OWC

OWC 256GB DDR4 3200 PC4-25600 CL22 8Rx4 288-pin 1.2V ECC Load Reduced LRDIMM memory upgrade

SKU CH-FKZ0-0HRFJ

Single 256 GB DDR4 3200 ECC load-reduced DIMM for Cisco UCS C240 M6 and C245 M6 servers

Capacity 256GB

  • Single 256 GB module doubles server capacity instantly
  • DDR4 3200 CL22 at 1.2 V cuts power draw per gigabyte
  • ECC load-reduced design keeps data intact under heavy workloads
  • JEDEC and RoHS compliant for warranty-safe upgrades
  • Backward compatible with 2133, 2400, 2666 and 2933 MHz systems

Single 256GB module for Cisco UCS servers

This OWC memory upgrade delivers a single 256GB DDR4 LRDIMM rated at 3200MHz PC4-25600 CL22. It is built for Cisco UCS C240 M6 and C245 M6 servers that require ECC load-reduced modules. The 288-pin design operates at 1.2V and targets administrators expanding memory capacity in compatible rackmount systems.

JEDEC and RoHS compliance with backward speed

The module meets JEDEC standards and RoHS requirements for a warranty-safe installation. It runs at 3200MHz and will also operate at 2133MHz, 2400MHz, 2666MHz and 2933MHz when the platform dictates a lower speed. This flexibility helps when populating mixed-speed slots or upgrading older chassis without replacing every DIMM.

Cannot mix with unbuffered or registered ECC DIMMs

Installation follows standard 288-pin LRDIMM procedure, but the module must not be combined with unbuffered or ECC registered memory in the same system. Population rules for Cisco UCS C240 M6 and C245 M6 platforms apply, so consult the server manual for supported slot configurations. Incorrect mixing prevents boot or triggers memory errors.

Questions about this item

Does the 256GB LRDIMM module require any periodic maintenance or scheduled replacement once installed?

The module is a solid-state component with no moving parts and no user-serviceable elements, so it does not require scheduled maintenance or replacement under normal server operation.

What is the first limit reached when the memory runs continuously at 3200MHz CL22 in a Cisco UCS C240 M6 or C245 M6?

The primary limit is the JEDEC-defined 1.2V operating voltage and CL22 latency at 3200MHz; sustained loads stay within these electrical and timing boundaries.

How much heat and power does the single 256GB 288-pin ECC Load Reduced DIMM produce when the server runs all day?

At 1.2V the module draws minimal power for its 256GB density, and its ECC Load Reduced design keeps thermal output low enough for standard server airflow cooling.
