64 GB DDR4 3200 Kit for Gigabyte B550

This 64 GB kit contains four 16 GB unbuffered UDIMM modules rated at DDR4 3200 with CL22 timings at 1.20 V. It is built for Gigabyte B550-AORUS motherboards and uses major OEM chips from Samsung, Micron or Hynix. The modules are non-ECC and have no heat spreaders.

Builders who need 64 GB on a B550-AORUS board

The kit suits users who want a matched four-module set validated for that specific motherboard. It is not for systems that require ECC or registered memory. Buyers needing lower latency or higher frequencies should look elsewhere, as should anyone whose board only supports two DIMM slots.

Four ranks of 2Rx8 give 64 GB total

Each module is dual-rank 2Rx8, so the kit populates all four slots with 64 GB of addressable capacity. This handles multitasking, content creation and virtual machines comfortably. Workloads that benefit from tighter timings or speeds above 3200 MT/s will not gain from this kit.

Questions about this item

What motherboard do I need to run this 288-pin DDR4 kit?

A DDR4-capable desktop board with four UDIMM slots that accepts 1.2 V non-ECC unbuffered modules.

Will the CL22 timing slow down my existing 3200 MHz sticks?

The motherboard will run all installed modules at the slowest common latency, so tighter-timed sticks will drop to CL22.

How can I confirm the full 64 GB is active after installation?

Check the BIOS memory summary or the OS task manager to see 64 GB detected at 3200 MT/s.
