Chinese memory manufacturer, Jiahe Jinwei, has commenced the mass production of its DDR5 memory modules. The DDR5 memory modules are based on DRAM chips from Micron who has started supplying memory makers with the next-generation solution that will be launching in the consumer desktop space by the second half of 2021.

Tech outlet, MyDrivers, broke the news and confirmed that the Jiahe Jinwei memory modules will be based on Micron's DDR5 DRAM. The specific DRAM bears the "IEA45-Z9ZSB" identifier though we cannot confirm the exact specifications of the chip right now. It is stated that DDR5 DRAM has no major difference compared to DDR4 DRAM in terms of size and dimensions however, the DDR5 technology is completely brand new and there are several underlying updates.
