TEAMGROUP Announces Industrial Wide Temperature DDR5 UDIMM and SODIMM

As a global memory leader with a long-term focus on industrial applications, TEAMGROUP has recognized the tremendous processing needs of the HPC market. To meet the demand for industrial memory can handle sustained high-speed data transmission with low latency, TEAMGROUP has utilized the in-house developed and patent-protected TRUST+ wide temperature technology to provide customers with high stability, durability and wide temperature industrial memory.

Applications for the first DDR5 UDIMM and SODIMM industrial wide temperature memory products include usage in edge computing, Internet of Vehicles, servers, AI, and embedded systems. In response to the stringent demands of efficient computing in the industrial control market, TEAMGROUP has been ready to launch the standard temperature DDR5 IST (TC: 0~85℃) memory series and the wide temperature DDR5 IWT (TA: -40~85℃) memory series. The latter features exclusive "Graphene-coated copper heatsink Technology" (U.S. Utility Patent US 11,051,392 B2), which helps maintain a case temperature (TC) of 85~86℃ under an ambient temperature (TA) of 85℃, ensuring low-latency high-speed computing. Without the heatsink, case temperatures (TC) can reach up to 89~90℃ or more, impairing the high performance of DDR5 and significantly reducing the life span of ICs.
The specifications of our industrial DDR5 memory are 16/32 GB per module, 4,800Mhz clock speed, CAS latency of 40-40-40, with 1.1 V operating voltage. It comes with on-die ECC function, which provides excellent stability and reliability, and added power management features to utilize power management ICs (PMIC). With better onboard power control to optimize signal integrity and interference resistance, the new DDR5 memory requires only a low operating voltage of 1.1 V, making it especially properly for low power consumption industrial automation, medical devices, POS systems, digital signage, thin clients, and other energy-saving or video applications. TEAMGROUP's DDR5 industrial memory product line will be available for compatibility testing in the third quarter of 2021 at the earliest and is expected to enter mass production in the fourth quarter of 2021.

How first low end tier low frequency DDR5 with voltage below basic voltage or previous generations of DDR will reach 85*C and needs of special heatsink? I think that this modules not needed of heatsink.

Did you not read the post? It's to ensure the modules can operate at an ambient temp of 85C, by keeping Tcase at ~86C instead of upwards of 90C.
This isn't your standard DDR5 module aimed at regular desktops or servers, but for very specialized computers that will operate at insane conditions.

Yes I read and heatsink is not an air conditioner and cannot dissipate heat coming from the external environment to the module, somewhere else in the universe.

You lost me.
A heatsink will more efficiently transfer the heat from the module into the ambient environment. Not the other way 'round.
I don't see what ACs have to do with the question?
I'm not saying the heatsink will bring it anywhere under the ambient temperature. Just more in-line with it, which is what literally every heatsink ever does.
A heatsink on these modules is the difference between running modules at 90C constantly in a 85C ambient temp, versus running them at 86C constantly at 85C ambient temp. Solely because of more efficient thermal transfer to the ambient environment.

Repeating this part of the text of the article does not attempt to explain
more convincing.

Despite the low 1.1 voltage these are still ddr5 4800 modules (still very fast) that are designed to run in confined, hot spaces hence the need for their new graphene heatsinks. They are simply demonstrating the heatsinks ability to maintain a near ambient temperature. Which is impressive in and of itself. There arent any passive heatsinks i have heard of to date that are capable of such impressive numbers (if true). They also explained how without the heatsinks (as you suggest) temps rose 5 to 6 degrees.
Its all in the article...
