32 GB DDR4 ECC kit for Gigabyte B550-AORUS

This NEMIX RAM kit supplies 32 GB of DDR4 memory in two 16 GB unbuffered UDIMM modules. It is built for Gigabyte B550-AORUS motherboards that accept ECC memory and need a straightforward capacity upgrade.

ECC unbuffered DDR4 3200 CL22 at 1.2 V

Each module runs at DDR4 3200 (PC4-25600) with a CAS latency of 22 and operates at 1.20 V. The 288-pin 2Rx8 organisation and on-die ECC provide error correction without registered buffering, matching the board's native memory controller.

Suits builders adding ECC stability

Users who need non-ECC memory, higher speeds, lower latency or larger single modules should consider other options. This kit is limited to the validated 32 GB capacity and the specified CL22 timing for the target platform.

Questions about this item

What does the DDR4 3200 speed mean once the kit is installed in a Gigabyte B550-AORUS board?

The modules run at 3200 MT/s with CL22 latency at 1.20 V, delivering the rated PC4-25600 bandwidth when the motherboard enables the XMP or DOCP profile.

How does the ECC unbuffered UDIMM interface affect error correction and maximum capacity on this platform?

ECC detects and corrects single-bit errors without a register, so the 2Rx8 16 GB modules work directly in the B550-AORUS UDIMM slots for 32 GB total.

What physical clearance and slot requirements must the board meet for these 288-pin DIMMs?

Each stick is a standard-height 288-pin DDR4 UDIMM with no heat spreader, so it fits any full-size DDR4 slot on the B550-AORUS without clearance issues.
