Intel has updated a new document, which lists the DDR5 memory packages that have been verified on the Alder Lake platform, some of which may be products that will be sought by enthusiasts in the future. Intel’s current list of certified suppliers has a feature, the memory inside is a dual-channel 32GB (16GB x2) package. Although there are also 16GB (8GB x2) packages on the market, it seems that most memory manufacturers choose to use 32GB (16GB x2) packages as the main product. Since the starting frequency of DDR5 memory is 4800 MHz, the general DDR5-4800 package generally does not need to be publicized.
Compared with DDR4 memory, the working voltage of DDR5 memory is lower, from 1.2V to 1.1V. However, except for DDR5-4800 and some DDR5-5200 in the list, higher frequency products will increase the voltage. Even if the same is DDR5-4800, the timings of different manufacturers are different. For example, the timing of Corsair is 34-35-35-69, while the timing of Kingston is 38-38-38-70.
At present, the highest frequency is G.Skill’s products. The Trident Z5 series
provides memory packages ranging from DDR5-6000 to DDR5-6666. The operating voltage is 1.35V and the timing is 40-40-40-76. However, G.Skill has set its own record for the fastest. It has previously announced the launch of a 32GB (16GB x2) package of DDR5-6800, which may also be on the QVL.
According to Intel’s official statement, the 12th-generation Core series processors support DDR5-4800, which means that any DDR5 memory exceeding this frequency will be considered overclocked. Although faster DDR5 memory is verified in the list of certified suppliers, PMIC is the key to whether the memory can run to DDR5-6000 or above. Since the Alder Lake platform and DDR5 memory are in their infancy, many issues are still being explored. Many memory manufacturers are eyeing DDR5-10000, but the difficulty of development and operation is not small.
