Server memory upgrade

This 64 GB DDR4 module delivers ECC Load-Reduced operation for compatible IBM-Lenovo servers and workstations. It runs at 2133 MHz with a CL15 latency and 1.20 V standard voltage. The 4Rx4 organisation helps maintain signal integrity on heavily populated memory channels. Buyers who need non-ECC or unbuffered DIMMs cannot use this product.

Tested reliability

Every unit undergoes quality assurance testing before shipment to verify dependable performance in demanding server workloads. The major-brand chipset and chips are validated for compatibility with IBM-Lenovo part numbers 95Y4812 and 95Y4814. No additional software, cables or cooling accessories are included in the package.

288-pin DIMM form factor

The standard DDR4 DIMM connector fits server boards that support Load-Reduced ECC memory at PC4-17000 speed. Installation follows normal DIMM seating procedures without special mounting hardware. Systems requiring RDIMM or UDIMM modules are not compatible with this LRDIMM design.

Questions about this item

Will the 4Rx4 ECC LRDIMM need any firmware updates or chip replacement over its service life?

The module uses major-brand chips tested to stringent standards and carries a lifetime warranty; no firmware updates or chip replacements are scheduled.

What is the first limit reached when this DDR4 2133 CL15 module runs sustained workloads?

The CL15 latency at 2133 MHz sets the throughput ceiling before thermal or voltage limits are encountered.

How much heat and power does the 1.2 V load-reduced DIMM generate during continuous operation?

At 1.2 V the module follows standard DDR4 power limits; the load-reduced design lowers electrical load on the memory bus, reducing heat in dense configurations.
