Corsair Says New DDR5 RAM Will Require Much Better Cooling

DDR5 memory is on the horizon, and leading manufacturers are gearing up for its release. Corsair is one of the brands that is preparing to release DDR5 RAM soon. The company revealed more about the possibilities of DDR5 RAM, as well as some of the difficulties, including the fact that it will run much hotter than DDR4.

The warm-up is not a surprise. The best RAM in the DDR5 lineup is going to be up to 4 times more powerful than its predecessor, thus generating more heat. However, according to George Makris, Corsair’s DIY Marketing Director, the reason also lies in the design of the memory module itself.

“DDR5 conceivably could run much hotter than DDR4, as they have moved voltage regulation off the motherboard itself, and now it is on the [RAM module], so you actually could be pumping a lot more heat,” said George Makris in a YouTube video posted on Corsair’s channel.

It has already been announced that the new DDR5 memory will feature speeds that were previously unheard of. Even the lowest clock speeds will be equal to or surpass the highest numbers generated by DDR4 RAM. Corsair has said that the data transfer rates will begin at 6,400 MT/s and go as far up as 12,600 MT/s. It’s also expected that the technology will support clocks up to 8,400MHz.

In addition to the speed increase, each RAM stick is going to have a much larger capacity. While DDR4 RAM features a maximum capacity of 32GB per dual in-line memory module (DIMM), new DDR5 memory will be capable of supporting up to 128GB. Such an impressive upgrade is bound to require better cooling. According to Corsair, achieving this kind of step-up is only going to be possible through enabling on-board power management integrated circuits (PMIC) as well as voltage regulating modules (VRM).

Heat spreaders were never really a point of consideration for RAM manufacturers — this applies to both the DDR3 and DDR4 eras. This may still change when it comes to DDR5, as the memory sticks become more complex and power-consuming pieces of hardware. Corsair claims that the current cooling systems it uses in manufacturing new DDR5 RAM will continue to keep the temperatures stable.

DDR5 technology has been developed with future hardware in mind. For today’s standards, the jump in performance might seem a bit overkill, but in a few years it’s likely to be the norm — and DDR5 is meant to support that advancement.

The future-proof scaling of the data transfer rate is made possible through several design choices. DDR5 RAM modules come with their own PMIC and VRM, allowing for some serious overclocking — but those components will require extra cooling. This is supported by an increase in voltage. Adata is already testing 1.6 Volt designs for its top-of-the-line DIMMs. The standard is 1.1 Volts, meaning a 45% increase from what we are currently used to. This kind of overvoltage will generate more heat.

Corsair is planning to release its first DDR5 memory modules late this year, likely meeting the deadline to launch alongside Intel’s 12th generation of processors. Whether cooling these impressively powerful RAM sticks will become a problem still remains to be seen, but it’s a good sign that Corsair remains aware of it ahead of time.

3TEETH + Ho99o9 Team on Aggressive New Song ‘Paralyze’

3TEETH tend to bring the aggression with aplomb, but the band is taking things to the next level on their latest track, delivering an industrial banger with a guest turn from Ho99o9.The two acts called upon DOOM composer Mick Gordon to co-produce the cut, adding to the techno-electric vibe of the cut. The band worked out the song last year, escaping their Los Angeles environs and settling down in a […]
