This includes the Z690, B660, and H610 chipsets. PMIC (Power Management Integrated Circuit)Ĭurrently, only Intel 600 series motherboards include the support for DDR5 RAM. Up to 512GB and up to 128GB (for mainstream PCs) Moreover, RAM modules are not backward compatible, you cannot use a DDR5 RAM module on a DDR4 motherboard or vice versa. It means you cannot use DDR5 RAM on a motherboard with DDR4 slots or vice versa even if the motherboard chipset includes support for both DDR4 and DDR5 RAM. Although both DDR5 and DDR4 come with 288 pins, they are electrically incompatible with each other, and also the module key notch is also different. So, technically it is not the real ECC but rather a slim-down version. The On-die ECC (ODECC) or Error Correction Code is DDR5 module specific only and provides ECC in the RAM chip or IC only and not throughout the whole channel or during the transport of data from RAM to the CPU. DDR5 operates at a lower voltage compared to DDR4 and comes with onboard power management integrated circuit (PMIC) whereas the power management of DDR4 RAM is handled by the motherboard.Īnother major addition to DDR5 RAM is that it comes with On-die ECC for correcting errors.

DDR5 RAM is the successor of DDR4 RAM and specifications-wise, DDR5 memory is way superior to DDR4 memory in all aspects whether it is speed, module capacity, power consumption, and bandwidth.

In upcoming years, you will be able to see widespread support for DDR5 RAM for most modern-day CPUs and motherboards.
