256GB DDR4 ECC RDIMM kit

This 256GB kit contains sixteen 16GB DDR4 3200 registered DIMMs with ECC and CL22 latency. It is built for ThinkMate Supermicro SuperServer platforms such as the 620P-TR, 620P-TRT, 220P-C9R and 220P-C9RT. System administrators upgrading memory in those qualified servers use this kit to reach the supported capacity.

1.2V registered modules without heat spreaders

Each module runs at 1.2V and carries a 1Rx8 organisation, keeping power draw low in dense configurations. The absence of heat spreaders reduces height for tight server chassis while the registered buffer lightens the electrical load on the memory controller. Typical idle and light-load operation stays quiet because the platform fans govern airflow across the bare PCBs.

Sustained load stability through stress testing

Every stick is stress tested under load before shipping to verify reliability during extended workloads. The registered ECC design corrects single-bit errors on the fly, preventing data corruption during long compute runs. This kit targets administrators who need maximum qualified capacity for the listed ThinkMate systems; builders needing non-ECC UDIMMs or higher frequencies should look elsewhere.

Questions about this item

How do I install the 16 registered DIMMs in the ThinkMate Supermicro servers, and what step is often missed?

Power down the server, open the chassis, align each 288-pin DDR4 RDIMM with the slot key, press firmly until both latches click, then verify in BIOS that all 256 GB at 3200 MT/s are recognised; the step often missed is confirming the registered modules are seated in the correct channel order per the motherboard manual.

What maintenance or replacement will the 16×16 GB ECC RDIMM kit need later?

No routine maintenance is required; the modules have no heat spreaders and run at 1.20 V, so only a failed stick would need replacement, which is covered by the lifetime replacement warranty.

What limit appears first under sustained load with the CL22 1Rx8 registered memory?

The CAS latency of 22 cycles at DDR4 3200 sets the timing floor; under continuous heavy workloads the memory controller will hit this latency ceiling before bandwidth or voltage limits become a factor.
