128 GB DDR4 kit for ASRock B450M
This 128 GB kit contains four 32 GB DDR4 3200 modules built for ASRock B450M motherboards. It targets builders who need maximum capacity on a four-slot board. The unbuffered non-ECC UDIMMs install without registration steps. Buyers who need ECC or registered memory cannot use this kit.
1.2 V operation at CL22 latency
The modules run at 1.20 V with a CAS latency of 22 at 3200 MT/s. Standard JEDEC voltage keeps power draw low and thermals modest under typical desktop loads. No heat spreaders are fitted, so airflow from the CPU cooler passes directly over the chips. Systems limited to lower voltages or tighter timings may not reach the rated speed.
Four 288-pin UDIMM slots required
The kit occupies all four DDR4 slots with 2Rx8 dual-rank modules. The motherboard must support 128 GB total and 32 GB per slot at DDR4 3200. Boards with only two slots or a lower per-slot limit cannot accept the full kit. Verify the board specification before purchase.

Questions about this item
How do I install the 288-pin DDR4 UDIMM modules on my ASRock B450M motherboard?
Align the notch on each 288-pin DDR4 UDIMM with the slot key, press firmly until the retention clips click, and populate all four slots for the 128GB kit to run at 3200MHz CL22 1.20V.
Will the Samsung, Micron, or Hynix chips on these 2Rx8 modules need any maintenance or replacement over time?
The DRAM chips are solid-state with no moving parts; no scheduled maintenance is required, and a lifetime replacement warranty covers any module that fails.
What thermal limit appears first when the 4x32GB kit runs sustained workloads at 3200MHz?
Without a heat spreader, the bare 2Rx8 ICs reach their throttling threshold before the 1.20V power limit becomes a factor.
