CORSAIR confirmed that DDR5 memory modules generate more heat

Although in the consumer market, platforms using DDR5 memory have not yet arrived, major manufacturers are already gearing up. According to the data of various memory manufacturers, the transfer rate of DDR5 memory ranges from 6400 MT/s to 12600 MT/s, which is much higher than that of DDR4 memory. Those extreme transfer rates are largely achieved by the onboard power management IC (PMIC) and voltage regulation module (VRM) of DDR5 memory.

In the past many years, memory basically does not require a special cooling module. In the past, in addition to some high-frequency DDR3 and DDR4 memory, users can also find JEDEC standard frequency memory. In the era of DDR5 memory, the heat dissipation of the memory will become complicated, and perhaps a simple heat sink is not so easy to meet the heat dissipation needs.

Recently, George Makris, director of DIY marketing at Corsair, stated on the official YouTube account that DDR5 memory will be hotter than DDR4 memory due to the transfer of the voltage regulation module from the motherboard to the memory PCB. Corsair memory product manager Matt Woithe also reiterated this point and said that CORSAIR’s exclusive dual-path heat exchange (DHX) is used to solve the heat problem of DDR5 memory modules.
With each generation of DDR memory in the past, the voltage has been decreasing. The voltage of DDR5 memory has been as low as 1.1V, and the function of the voltage regulation module is huge. On the other hand, some high-end high-frequency DDR5 memory will increase the frequency by increasing the voltage. For example, ADATA stated that the voltage of the DDR5 memory with a rate of 12600 MT/s is 1.6V, which will greatly increase the heat of the memory.  At the same time, DDR5 memory also has an ECC verification function, which greatly improves stability, but CORSAIR did not confirm whether this function will increase heat generation. Corsair is expected to release the first batch of DDR5 memory at the end of this year to meet the Intel Alder Lake platform.
