NEMIX RAM 512GB (8x64GB) DDR4 3200 CL22 2Rx4 ECC RDIMM KIT Gigabyte WRX80-SU8-IPMI memory upgrade

512 GB DDR4 ECC RDIMM kit for Gigabyte

This 512 GB kit contains eight 64 GB DDR4 3200 registered DIMMs built for the Gigabyte WRX80-SU8-IPMI motherboard. Each module runs at 1.2 V with CL22 latency and uses a 2Rx4 organisation. The ECC registered design targets servers and workstations that require error correction and signal integrity at high capacity.

288-pin RDIMM installation and population rules

The modules use the standard 288-pin DDR4 RDIMM form factor and install vertically into the board's DIMM slots. Registered DIMMs place a register between the DRAM and the memory controller, so the motherboard must support registered memory; unbuffered slots will not work. Populating all eight channels requires the CPU to provide enough memory channels and the BIOS to be configured for the full kit. Mixing ranks or speeds can prevent the system from posting at the rated 3200 MT/s.

DDR4 3200 registered ECC limits

DDR4 3200 sets the maximum data rate at 3200 MT/s (PC4-25600) when the memory controller and BIOS support it. Registered ECC modules add one clock cycle of command latency compared with unbuffered DIMMs, which slightly reduces absolute latency at a given frequency. The 1.2 V operating voltage is fixed for standard DDR4; the kit does not support higher-voltage profiles. Total capacity is limited to the 512 GB provided by the eight modules.
