OWC 128GB DDR4 ECC RDIMM for ASUS KRPA-U16

This 128GB DDR4 3200 registered DIMM provides error-correcting memory for ASUS KRPA-U16 motherboards and RS720 rack servers. It is built for workstations and servers that require ECC registered modules. Standard desktop computers cannot use this memory type. Mixing with unbuffered or load-reduced DIMMs is not supported.

Single 128GB module with JEDEC compliance

The upgrade consists of one 128GB 8Rx4 module operating at 1.2V with CL22 latency. JEDEC-standard and ROHS-compliant design meets OEM specifications for a warranty-safe installation. No heat spreader is fitted on the module. The registered buffer and ECC functionality are integral to the DIMM itself.

DDR4 3200 with backward speed compatibility

The PC4-25600 module runs at 3200MHz and will also operate at 2133MHz, 2400MHz, 2666MHz and 2933MHz when installed in slower platforms. It uses the 288-pin DDR4 interface exclusively. Systems requiring unbuffered, load-reduced or non-ECC memory are not compatible with this registered ECC DIMM.

商品問答

Will the 128GB 8Rx4 DDR4 module need any firmware updates or component replacements during its service life?

The module is a JEDEC-standard 1.2V DDR4 ECC registered DIMM with no heat spreader and no moving parts, so it requires no firmware updates or scheduled component replacements.

What limit appears first when the 3200MHz CL22 registered memory runs sustained workloads on the ASUS KRPA-U16?

The registered buffer and CL22 latency set the timing ceiling, while the 1.2V DDR4 specification defines the thermal and power envelope that the server chassis must dissipate continuously.

How much heat and power does the 128GB 288-pin ECC RDIMM produce when the server runs all day at 3200MHz?

Operating at 1.2V without a heat spreader, the module stays within standard DDR4 power limits; the ASUS KRPA-U16 platform airflow handles the resulting heat during continuous operation.
