Memory maker Teamgroup has announced that the company is starting to validate the first consumer-level DDR5 memory modules. Currently, it is testing 16GB 4800MHz kits at 1.1volts with major motherboard vendors ASUS, Gigabyte, MSI and ASRock. These specs are in line with what SK Hynix released as a reference back in October. Teamgroup hopes to be the first to be out with consumer DDR5 kits with planned availability in Q3 2021.
Intel reportedly plans to add support for DDR5 with its Alder Lake-S platform around that same time frame, and AMD will purportedly bring DDR5 support a bit later in 2022 with Zen 4 and might possibly debut next-gen Socket AM5 as well.
Interestingly, Teamgroup states that DDR5 memory will not require users to enter the BIOS and enable Intel Extreme Memory Profile (XMP) or similar RAM overclocking mechanisms. So it's likely that the memory kit you buy will run at its tested speed by default as long as your processor and motherboard support that speed. This in addition to Error Correcting Code (EEC) support - as previously stated by SK Hynix - implies that consumer-level DRAM will see a big generational leap with the upcoming DDR5 standard.
