Server memory upgrade

This 16 GB DDR3 1066 MHz registered ECC module replaces Micron MT72JSZS2G72PZ-1G1D1DF and MT72JSZS2G72PZ-1G1M1 parts in compatible servers and workstations. It delivers 1.5 V operation with CL3 latency and a 4Rx4 organisation for data-integrity workloads.

Replacing older DDR3 ECC RDIMMs

The jump is worthwhile when a system requires registered error-correcting memory at PC3-8500 speed and the existing slots accept 240-pin DIMMs with 4Rx4 density. Buyers who need higher frequencies, lower voltages or unbuffered modules cannot use this product.

Straightforward DIMM installation

Align the 240-pin module with the keyed slot, press evenly until the retention clips engage, then verify the configuration in BIOS. The most common issue is mixing registered and unbuffered DIMMs or exceeding the platform’s rank-per-channel limit, which prevents the system from posting.

Questions about this item

Will the 240-pin DDR3 DIMM fit my server's registered memory slots?

This module uses the standard 240-pin DDR3 DIMM form factor for registered ECC memory; verify your system requires DDR3 RDIMMs before ordering.

What is the correct way to seat a 4Rx4 registered module so the server recognises the full 16 GB?

Align the notch with the slot key, press firmly until both locking tabs click, then confirm the BIOS shows 16 GB at 1066 MHz with ECC active.

How do I know when a 1.5 V DDR3 ECC RDIMM needs replacement?

Run a memory diagnostic if you see corrected ECC errors in logs, random reboots, or the system reports less than 16 GB at POST.
