DDR5 production is gaining momentum, with several manufacturers already finalizing their designs for mass production of next-generation RAM. This standard is supported by the upcoming Intel Alder Lake and AMD Raphael platforms, which are expected to launch later this year.
Chinese company Jiahe Jinwei, a sub-brand of Longsys, has announced that it is leaving its assembly line at its Shenzhen plant of the first batch of DDR5 memory modules. The modules are already in production and will go on sale alongside next-generation platforms from Intel and AMD. Intel is expected to play a major role in promoting DDR5 with its Z690 motherboards for 12th Gen Intel Cores.
The pair of modules in the photos with a green PCB is from Jiahe Jinwei, while another image posted by Uniko’s Hardware shows memory sticks from another manufacturer using a black PCB.
The most unusual and noticeable feature of both U-DIMMs, besides the DRAM chip layout, is the built-in power management circuit, which is designed to receive 5V voltage from the motherboard and transfer it to DRAM chips more efficiently than in the case of DDR4. By placing the voltage conversion components on the module itself, current losses and noise will be reduced, giving more overclocking options.
A batch of DDR5 memory modules from Jiahe Jinwei differs at 4800 MHz at a voltage of 1.1 V, but also in higher latencies: the timings are set to CL40-40-40. Each bracket has a capacity of 16 GB, but DDR5 DIMMs with a volume of 32 GB is already being designed. The memory has a built-in Error Correction Code (ECC) and differs from DDR4 in lower power consumption and increased stability. Also, one module will be able to work in the two-channel mode for increased productivity.
Faster modules will appear in the future – manufacturers are reporting the theoretical possibility of reaching frequencies above 10 GHz in extreme overclocking. With DDR4 overclocked to over 7GHz, the new pinnacle doesn’t seem like an insurmountable obstacle for the next generation memory chips from SK Hynix and Micron.
