Chinese memory manufacturer, Longsys, has released test results of its DDR5 memory modules which were evaluated on an Intel Alder Lake Desktop platform comprising of an 8 core chip. The performance data was measured on Longsys DDR5 ES1 modules which were released today and offer speeds of up to 6.4 Gbps.

Longsys's DDR5 memory module that was tested today features two variants, both of which come in UDIMM form factor. We have a single Rank (x8) and the dual-rank (x8) modules with the first one featuring 16 GB capacity (JDEC R/C A 0.50) & the second featuring 32 GB capacity (JDEC R/C B 0.51). Both variants feature 4800 MHz pin speeds, CL40 (40-40-40-77) timings, make use of 16Gb (2x8b) modules and have voltages rated at 1.1/1.1/1.8V (VDD/ VDDQ / VPP). The Longsys DDR5 memory modules also make use of an 8 layer PCB design and measure 133.35x31.25x1.27mm in terms of dimensions.
