64GB DDR4 3200 ECC kit

This 64GB kit contains four 16GB DDR4 3200 ECC unbuffered UDIMM modules. It is built for SuperMicro motherboards using the B3ST1-CPU-001 platform where error-correcting memory is required. System integrators and IT teams choose it for workloads that demand data integrity.

Fits SuperMicro B3ST1-CPU-001 boards

The modules install directly into the board's 288-pin DDR4 slots and run at 1.2V with CL22 timing. No heat spreaders are fitted, so the DIMMs sit low and leave clearance for standard CPU coolers. ECC support is handled by the motherboard chipset, freeing the system from silent data corruption.

Upgrades from smaller or non-ECC sets

Replacing a partial population or non-ECC memory with this matched 4x16GB kit enables full-channel bandwidth and error correction in one step. The jump is worth it when the platform supports DDR4 3200 ECC UDIMM and the application cannot tolerate uncorrected memory errors.

Questions about this item

How does CL22 latency affect sustained throughput on this DDR4 3200 kit?

CL22 sets the minimum cycle delay for each column access; at DDR4 3200 the kit delivers 25600 MB/s peak bandwidth, and the fixed 22-cycle latency becomes the limiting factor once the memory controller saturates all four 16 GB ranks.

What thermal or acoustic impact should be expected when all four modules run continuously at 1.2 V?

The modules operate at 1.2 V without heat spreaders, so they rely on case airflow; power draw stays within standard DDR4 limits and the kit adds no moving parts, making acoustic impact negligible in a ventilated chassis.

Which motherboard feature must already be present for this 288-pin ECC UDIMM kit to function?

The board must provide DDR4 ECC unbuffered UDIMM slots wired for 2Rx8 organisation; the target platform is the Supermicro B3ST1-CPU-001, which exposes four such slots for the 64 GB kit.
