128GB DDR3 ECC RDIMM kit

This 128GB kit contains four 32GB DDR3 1600 CL11 registered DIMMs built for Supermicro X9DAE, X9DAi, X9DBS, X9SRA and X9SRE motherboards. It targets servers and workstations that require ECC registered memory for data integrity.

Verify registered ECC support

Your board must accept 240-pin DDR3 registered ECC modules at 1.5V and support 4Rx4 density. Unbuffered consumer memory will not work in these slots and mixing registered with unbuffered types is not supported.

Replaces smaller DDR3 registered kits

The upgrade makes sense when moving from lower-capacity registered ECC sets or when populating empty slots on compatible X9-series boards. It is not suitable for desktop platforms that only accept unbuffered memory.

Questions about this item

What is included in the box and do I need to buy anything else to install the 128GB kit?

The kit contains four 32GB DDR3 1600 CL11 ECC registered RDIMM modules. No extra parts are required if your Supermicro X9-series motherboard has four free 240-pin slots.

How do I decide between this 128GB (4x32GB) kit and a smaller capacity for my X9DAE or X9SRE board?

Choose the 128GB kit when your workload needs the maximum registered ECC capacity the board supports; select a smaller kit if you only need to fill fewer slots or want to leave room for later expansion.

What does the PC3-12800 1600MHz CL11 rating mean once the modules are running in my server?

The modules will operate at 1600MHz with a CAS latency of 11 cycles at 1.5V, delivering the standard JEDEC DDR3 bandwidth for registered ECC memory in compatible Supermicro X9 platforms.
