Kingston ValueRAM 64GB 6400MHz DDR5 Desktop Memory (KVR64A52BD8-64)

The Kingston ValueRAM KVR64A52BD8-64 is a 64 GB DDR5 desktop memory module designed for users who need high-capacity, high-speed RAM in a single DIMM. Running at 6400 MHz (PC5-51200) with a CAS latency of CL52, this module delivers the data bandwidth that modern multi-core processors demand, helping reduce memory bottlenecks when working with large datasets, virtual machines, or complex creative workloads. The module uses a 288-pin CUDIMM (Clock-buffered UDIMM) form factor, which incorporates an integrated clock driver (CKD) on the PCB. This clock driver re-drives the clock signal, extending signal integrity at higher frequencies while preserving the unbuffered data path — giving users the latency benefits of an UDIMM alongside improved signal stability at DDR5-6400 speeds. The unbuffered architecture means commands and addresses are passed directly to the DRAM chips without an additional register, keeping access latency lean. Built on a 2Rx8 configuration (dual-rank, ×8 die organisation), the module is specified as 8G × 64-Bit and incorporates Die ECC (ODECC). ODECC corrects single-bit errors internally within the DRAM die itself before data reaches the memory controller, improving reliability for everyday desktop use without requiring an ECC-capable motherboard or processor. Power delivery is handled at DDR5-standard voltages: VDD and VDDQ are both 1.1 V typical, VPP is 1.8 V typical, and VDDSPD ranges from 1.8 V to 2.0 V. The PCB height is 1.23 inches (31.25 mm) — a low-profile dimension that aids clearance in compact chassis and around tall CPU coolers. The module is RoHS compliant and halogen-free, reflecting Kingston's environmental standards for materials.
