Chinese RAM Kits Adopt Homegrown 24 Gb DDR5 Memory Modules

Chinese companies like Gloway and KingBank, which provide DDR5 memory kits for consumer platforms, have started integrating domestically produced CXMT DDR5 memory into their RAM kits, effectively ending their reliance on DRAM from Micron, SK hynix, and Samsung after years of external dependence. It has been reported that Gloway and KingBank have begun incorporating CXMT’s 24 Gb DDR5 modules, which are being shipped as part of 48 GB RAM kits. With 3 GB per module, this results in eight modules per DDR5 DIMM for a total of 24 GB of capacity. In the regular dual DIMM configuration, Gloway and KingBank are offering consumers 48 GB of capacity.

Gloway has prepared the Longwuyi Yi Special Edition kit, which operates at 6,000 MT/s with latencies of CL36-38-38-80. This kit runs at a voltage of 1.2 V and is specialized for AMD CPUs. Reportedly, it features custom heat spreaders to maintain cooling and control heat dissipation, with 5 W/mK thermal pads included. Meanwhile, KingBank DIMMs use 2 mm heat spreaders and have a custom thermal interface material applied over the PMIC, along with dual-side RGB LED lighting that can be controlled via software.

Earlier this year, we confirmed that CXMT began shipping 16 Gb DDR5 chips running at 8,000 MT/s, which measure 67 mm² and have a density of 0.239 Gb per square millimeter. The G4 DRAM cells are 20% smaller than CXMT’s previous G3 generation. This development follows the company’s progression from 23 nm (G1) and 18 nm (G2) nodes. However, it seems that 24 Gb modules are now in mass production, but at slightly lower speeds of around 6,000 MT/s. Presumably, additional clock drivers and other tuning will be needed to achieve higher transfer rates.
