Capacity and Compatibility

This NEMIX RAM kit provides 64GB of DDR4 3200 memory across four 16GB UDIMM modules. It is built as an ECC unbuffered kit for ASUS server motherboards that support Intel Xeon E-2300 processors on the LGA 1200 platform.

Suitable Builders and Limitations

The kit suits administrators upgrading compatible ASUS micro-ATX server boards that require ECC unbuffered DDR4 at 1.2V. Builders using consumer desktop motherboards without ECC support or systems needing registered DIMMs should look elsewhere.

Deciding Specification

The modules run at CL22 latency with a 1Rx8 organisation and 288-pin DDR4 interface. Confirm that the target motherboard qualifies unbuffered ECC UDIMMs at this speed and rank before purchase.

Questions about this item

Does this kit need a motherboard with four DDR4 288-pin UDIMM slots running at 1.2 V?

Yes. The 64 GB kit contains four 16 GB DDR4 3200 ECC UDIMM modules at 1.20 V, so the board must provide four 288-pin DDR4 slots that support unbuffered ECC at that voltage.

Will the CL22 timing on these modules force a slower DDR4 3200 kit already in the system to run at CL22?

When mixed, the motherboard typically defaults all modules to the slowest common timing, so an existing DDR4 3200 kit with tighter latency would likely run at CL22 to match these 1Rx8 modules.

How can I confirm the system sees all 64 GB with ECC active after installation?

Check the BIOS memory summary or OS tools such as dmidecode on Linux or Task Manager on Windows; they should report 64 GB total and show ECC enabled for each 16 GB module.
