Leading suppliers of enthusiast memory modules such as Corsair have announced that their upcoming DDR5 SDRAM memory sticks have unprecedented data transfer rates, starting from 6400 MT/s to 12600 tons/secCorsair said this week that, to a large extent, this extreme speed will be achieved through the on-board power management IC (PMIC) and voltage regulation module (VRM), which will require proper cooling.
“As you can imagine, DDR5 can run hotter than DDR4 [as] They have moved the voltage regulation away from the motherboard itself, and now it’s [module], So you can actually generate more heat,” Corsair’s DIY marketing director George Makris said in a statement. YouTube video From the company.
For many years, many people believe that most DDR3 and DDR4 modules do not require a heat sink, even those used in audiophile PCs. With DDR5, the situation may change as modules become more complex. Corsair said its upcoming cooling system for DRAM sticks will complete this work.
DDR5 was developed to support real performance expansion in the coming years. This data transfer rate scaling is achieved by multiple architectural features of DDR5, which will allow DRAM manufacturers to produce DDR5-12600 chips that comply with the JEDEC standard in the future. However, it seems that no manufacturer will produce DDR5-10000 or DDR5-12600 DRAM ICs in 2021 or 2022. Therefore, to manufacture suitable DIMMs, manufacturers must carefully select capable chips and increase the voltage above the normal 1.1 volts. And to ensure high-quality power delivery.
Since DDR5 modules have their own PMIC and VRM, module manufacturers can develop quite powerful solutions to allow overclocking.For example, Adata is already considering 1.6 Volts For its top DIMM (we can only wonder how the memory controller of the CPU produced with 5nm or 7nm process technology handles such a signal voltage, which is 45% higher than the standard 1.1 volts. This extreme overvoltage will obviously make the memory The chip is very hot. In addition, the PMIC and VRM components must also be cooled. Therefore, the audiophile DDR5 module (at least The best RAM module) It may require better cooling than similar DDR4 products.
Corsair has extensive experience in designing complex cooling systems for its Dominator memory modules. These systems can not only directly cool the DRAM chip itself, but also cool the module’s PCB, because the latter has a special layer. For this reason, Corsair is convinced that it will also provide a comprehensive radiator for DDR5 modules.
