NEMIX RAM
A 128 GB DDR4 ECC RDIMM kit of sixteen 8 GB modules running at 3200 MT/s with CL22 latency and 1.2 V operation for compatible ThinkMate Supermicro servers
This 128GB kit contains sixteen 8GB DDR4 3200 registered DIMMs with ECC and a CAS latency of CL22. It operates at 1.2V using 1Rx8 organisation and 288-pin form factor. The modules are validated for Thinkmate Supermicro SuperServer platforms including the 620P-TR, 620P-TRT, 220P-C9R and 220P-C9RT.
Upgrading from smaller RDIMM kits or unbuffered DIMMs adds the error correction and signal buffering required for stable multi-socket server workloads. The jump is worth it when your workloads demand maximum registered capacity per channel and the platform qualified vendor list matches the 220 and 620 series systems listed.
These modules only fit 288-pin DDR4 RDIMM slots and will not work in desktop UDIMM, SO-DIMM or DDR5 sockets. Compatibility is restricted to the specific Thinkmate Supermicro models identified; other servers, workstations or consumer boards are not supported by this kit validation.

Yes, the 288-pin DDR4 RDIMM form factor matches the registered DIMM slots on the listed THINKMATE Supermicro SuperServer models.
Populate all sixteen slots following the motherboard manual channel order; the common mistake is leaving a channel partially filled which prevents the server from posting.
Run a full memory diagnostic once after initial install and again after any firmware update; ECC corrects single-bit errors but periodic testing confirms module health.
