8 GB DDR4 3200 UDIMM for ASRock B660M

This 8 GB DDR4 module runs at 3200 MT/s with a CAS latency of 22. It is built as a single-rank 1Rx8 unbuffered DIMM without a heat spreader. The kit targets owners of ASRock B660M-HDV, B660M-ITX/ac or B660M-ITX/eDP motherboards who want a straightforward capacity increase.

Check your motherboard slots

Verify that your board has a free 288-pin DDR4 slot and supports non-ECC unbuffered UDIMMs at 1.2 V. Confirm the maximum memory per slot and the total capacity limit in the motherboard manual. Ensure the BIOS is updated to the latest version for full compatibility with this speed grade.

Fits a standard desktop build

The module plugs directly into a 288-pin DDR4 slot and draws 1.2 V, leaving other slots open for future expansion. It requires no extra power cables, cooling or software setup. The single 8 GB stick adds capacity while keeping remaining slots available for a matched pair later.

Questions about this item

Does the package include only the 8GB UDIMM or are extra items such as a screwdriver or thermal pad supplied?

The package contains one 8GB 288-pin DDR4 UDIMM module and nothing else; no tools or pads are included.

Should I pick the CL22 3200 MT/s stick or a different latency if my board is an ASRock B660M-HDV?

This module is validated for the B660M-HDV, B660M-ITX/ac and B660M-ITX/eDP boards at CL22 3200 MT/s, so choose this version for guaranteed compatibility.

Will the 3200 MT/s rating actually run at that speed once installed in a B660M system?

The board will operate the stick at 3200 MT/s with 1.20 V and CL22 timings provided the BIOS is set to the standard profile.
