64GB DDR4 ECC kit for Supermicro servers

This 64GB kit contains four 16GB DDR4 3200 unbuffered ECC UDIMMs built for specific Supermicro motherboards. It targets administrators who need validated memory for supported workstation or server boards. Systems requiring registered DIMMs or higher densities cannot use this kit.

DDR4 3200 unbuffered ECC limits

The modules run at DDR4 3200 with CL22 timing and 1.2V operation. Unbuffered ECC tops out at lower capacities than registered memory and does not support the signal buffering required by some multi-socket platforms. Boards that demand registered DIMMs will not accept these sticks.

Plain green UDIMMs with standard 288-pin layout

No heat spreaders are fitted, so the modules sit low in tight server chassis and rely on case airflow. The 288-pin edge connector matches the DDR4 UDIMM socket keying used on the listed Supermicro models. Four single-rank sticks populate four slots directly without extra cabling or brackets.

Questions about this item

Is the 64GB kit the right size or should I pick a smaller 16GB module?

The kit contains four 16GB modules for 64GB total; choose it if your board has four slots and you want the full capacity, otherwise select a smaller kit that matches your slot count.

What does DDR4 3200 actually deliver once installed?

The modules run at 3200 MT/s with CL22 latency at 1.20V, giving the rated PC4-25600 bandwidth when the motherboard enables the DDR4 3200 profile.

Does the ECC UDIMM work on standard 288-pin DDR4 slots?

Yes, it uses the 288-pin DDR4 UDIMM form factor with ECC and unbuffered operation, so it fits standard DDR4 DIMM slots that support ECC memory.
