64 GB DDR4 3200 ECC kit

This 64 GB kit contains four 16 GB DDR4 3200 ECC UDIMM modules rated at CL22 and 1.2 V. It is built for Gigabyte B550-AORUS motherboards that accept 288-pin unbuffered ECC memory. The dual-rank 2Rx8 organisation and Samsung, Micron or Hynix chips target workloads that need error correction without registered DIMMs. ||

Suited for ECC builds only

Builders who need ECC on a consumer platform will find the correct pin count, voltage and rank layout here. Systems that cannot enable ECC in BIOS or that require registered DIMMs will not benefit from these modules. Buyers without ECC support in their motherboard should look elsewhere. ||

288-pin unbuffered ECC UDIMM

The decisive specification is the 288-pin unbuffered ECC UDIMM form factor at DDR4 3200. Only motherboards that list 288-pin DDR4 ECC UDIMM support at 1.2 V can use this kit; registered or non-ECC slots are electrically incompatible. ||

Questions about this item

How do I install the four 288-pin DDR4 ECC UDIMM sticks on my Gigabyte B550-AORUS motherboard?

Power off, open the case, align each module's notch with the slot key, press straight down until both retention clips click, then populate all four slots for 64 GB total.

What upkeep or replacement will this ECC unbuffered kit need over time?

No moving parts or heat spreaders to service; keep slot contacts dust-free and rely on the manufacturer's lifetime replacement if a module ever fails.

At sustained load, which limit appears first — voltage, latency or thermal?

Fixed 1.20 V operation and CL22 latency mean the first ceiling is the DDR4 3200 transfer rate; the kit runs at that spec without overclocking headroom.
