RIMLANCE
128 GB server memory kit (2 × 64 GB DDR4 3200 LRDIMM, CL22, ECC registered, 4Rx4)
This RIMLANCE kit provides 128 GB of DDR4 server memory in a matched pair of 64 GB LRDIMMs. It is built for administrators who need large memory pools for virtualization, databases or other memory-intensive workloads. The modules are new and use a 288-pin registered form factor with ECC.
The modules run at DDR4 3200 (PC4-25600) with a CAS latency of 22 and operate at 1.2 V. Performance is bound by the DDR4 standard and the memory controller in the host server; speeds above 3200 MT/s are not supported by these DIMMs. Mixing with modules of different speeds, ranks or voltages will force the system to run at the lowest common settings.
Each 64 GB module uses a 4Rx4 load-reduced organisation that reduces electrical load on the server memory bus. This rank structure is the decisive factor for compatibility — only platforms qualified for 4Rx4 LRDIMMs at this density will recognise the full capacity. Servers limited to lower rank counts or standard RDIMMs cannot use this kit.

The kit contains two 64 GB LRDIMMs for a total of 128 GB; choose it when your server needs that much registered ECC memory in a two-module package.
The modules run at 3200 MT/s with CL22 timing, giving the bandwidth and latency specified for PC4-25600 operation when the platform supports that speed.
The 288-pin DDR4 LRDIMM format provides registered ECC signalling and a 4Rx4 organisation, allowing higher density per slot while the memory controller drives the electrical load.
