NEMIX RAM 512GB (4x128GB) DDR4 3200 ECC RDIMM THINKMATE Supermicro SuperServer memory upgrade

512GB DDR4 ECC RDIMM kit for THINKMATE Supermicro

This 512GB memory kit contains four 128GB DDR4 3200 registered DIMMs built for THINKMATE Supermicro SuperServer platforms. It targets IT teams upgrading 620P-TR, 620P-TRT, 220P-C9R or 220P-C9RT systems that require ECC registered memory. Each module operates at 1.2V with a CL22 latency and a 4Rx4 organisation. The kit delivers 512GB total capacity across four 288-pin slots.

DDR4 3200 registered ECC limits

DDR4 3200 registered ECC memory tops out at 3200 MT/s on platforms that support PC4-25600 speeds. The registered buffer adds one clock cycle of latency compared with unbuffered modules, so maximum throughput depends on the motherboard memory controller and populated slot count. Filling all channels with 4Rx4 ranks can reduce the achievable frequency below the rated 3200 MT/s on some Supermicro boards. The 1.2V operating voltage is fixed for this DDR4 standard.

4Rx4 rank density decides fit

The 4Rx4 rank structure on each 128GB module determines whether the Supermicro memory controller can address the full 512GB across four slots. Some server platforms limit the number of logical ranks per channel, so a 4Rx4 configuration may not be supported on every listed model. Verify the platform rank limit in the system documentation before purchase. If the board caps ranks per channel lower than four, the modules will not initialise.
