  • Validated for ASRock B660M motherboards including HDV ITX ac and eDP models

ASRock B660 compatible 64 GB kit

This 64 GB DDR4 kit contains two 32 GB unbuffered UDIMM modules built for ASRock B660M-HDV, B660M-ITX/ac and B660M-ITX/eDP motherboards. It runs at 3200 MT/s with CL22 latency at 1.20 V. The modules use major OEM chips from Samsung, Micron or Hynix and carry no heat spreader.

Two-slot 288-pin DDR4 upgrade

Each module is a 2Rx8 dual-rank 288-pin DDR4 DIMM that occupies a single standard memory slot. The kit adds 64 GB total capacity without requiring ECC or registered support. It frees no additional slots beyond the two used and needs no extra cooling hardware because the design is bare.

Sustained load stability validated

All modules undergo rigorous stress testing under load before shipping to confirm stability during extended workloads. The 1.20 V operating voltage and standard JEDEC timings keep thermal output predictable over long sessions. Buyers who need ECC error correction or registered buffering should choose a different memory type.

Questions sur cet article

Will CL22 latency become a bottleneck during sustained heavy workloads?

CL22 is the rated CAS latency at DDR4 3200; it remains constant under load and does not throttle further.

How much heat and power should I expect from this 1.20 V kit running all day?

The modules run at 1.20 V with no heat spreader; power draw stays at standard DDR4 3200 levels and thermals are typical for unbuffered UDIMMs.

Do I need an ASRock B660M motherboard with four 288-pin slots to use both 32 GB modules?

The kit is validated for ASRock B660M-HDV, B660M-ITX/ac and B660M-ITX/eDP boards; each module fits a standard 288-pin DDR4 UDIMM slot.
