DDR4 3200 64GB kit for MSI builds

This 64GB kit contains four 16GB DDR4 UDIMM modules rated at 3200MHz with CL22 timings. It is built for desktop PCs using MSI B550M PRO-VDH WiFi motherboards and similar platforms that accept non-ECC unbuffered memory. The 1.2V operating voltage matches standard DDR4 specifications.

Four-slot population frees no extra DIMM slots

The kit fills all four UDIMM slots on a typical consumer board, so no further memory can be added without removing modules. Each stick is a 2Rx8 288-pin DIMM without a heat spreader, keeping the profile low for CPU cooler clearance. Installation follows the motherboard manual for dual-channel operation.

64GB handles heavy multitasking and virtual machines

At this capacity the system can run multiple VMs, large creative projects and memory-hungry databases without paging. The CL22 latency and 3200MHz data rate provide solid throughput for everyday workloads. Builds needing more than 64GB or lower latency timings will require a different memory configuration.

Questions about this item

Will the CL22 latency become a bottleneck under sustained heavy workloads?

CL22 is the rated CAS latency at DDR4 3200; it remains constant during sustained operation and does not shift with temperature or load.

How much heat do the four modules generate when running all day at 1.2 V?

The kit operates at 1.20 V with no heat spreader, so thermal output stays low enough for standard case airflow to keep temperatures in check.

Does my motherboard need four free 288-pin DDR4 slots to use this 64 GB kit?

Yes, the kit contains four 16 GB UDIMMs that each require a 288-pin DDR4 slot, so four available slots are necessary.
