Transcend last week introduced a family of DDR4 SO-DIMMs that can operate in extreme temperature conditions. The modules are designed for industrial computers, special-purpose PCs, POS, ATM and other systems that work in rough environments for 24/7. Subsequently, the SO-DIMMs can be used safely in SFF PCs without decent cooling for prolonged amounts of time.

Transcend’s new industrial grade memory modules use special PCBs that have industrial-grade capacitors, 30μm gold-plated contacts and are designed to withstand shock, electromagnetic disturbance and extreme temperatures from –40°C to +85°C. In theory, it means that the SO-DIMMs are rated to operate in Antarctica or in the Lut Desert in Iran. In the real world, Transcend’s new SO-DIMMs will be used inside space-constrained industrial PCs, military systems, embedded systems and others that work 24/7 in rough conditions and/or without decent cooling.

Module Capacity Speed Voltage ECC Part Number
8 GB (ECC) DDR4-2400 1.2 V Yes TS1GSH72V4B-I

The new industrial-grade modules from Transcend are based on Samsung’s 8 Gb B-die DDR4 chips (marked as K4A8G08) that were hand-picked and tested to run in extreme conditions. The SO-DIMMs come in 8 GB and 16 GB configurations and are rated to operate at 2400 MT/s at 1.2V, which means that they are fully compatible with the industrial-grade, embedded and low-power CPUs that support DDR4 at JEDEC speeds. The new modules carry Transcend’s lifetime warranty.

Pricing of Transcend’s new industrial-grade DDR4 modules is unknown as for industrial customers it typically depends on actual sales volumes. We would expect the modules will be more expensive than typical SO-DIMMs because they use special PCBs with 30μin gold plating, components with extended temperature ranges as well as cherry-picked memory ICs.

    I know the conditions sound extreme like a place nothing would ever be asked to operate in, but take an enclosed chassis with stuff running and give the laptop to a guy who has to do some diagnosis on a generator housed in a windmill on the Tehachapi pass or a mechanic having to pull codes from a transmission on a truck in the snow. Suddenly those temps actually matter.

    Yeah, even just a boring old electrical panel becomes hell to a regular computer if it's +30 C outside and there's no active ventilation. Many small-form-factor industrial PCs I've worked with are 100% passive (on purpose) so components like this are quite important.

    There's more than one component in a laptop, are all of them made to work at those temps? Doubt it.

    Consumer and business laptops are not designed for wide temperature operation in most cases. However, there are ruggedized laptops and industrial-grade computer systems that are built with such conditions in mind. Having suitable memory is beneficial to OEMs that produce those sorts of products.

    even in Austria we sometimes have -20°C for 1 or 2 weeks a year. So for systems required to run 100% of the time it really makes a lot of sense to use such RAM.

    Well I've lived in northern Canada and in the badlands. -40C to +40C is all too common.

    Sort of looks like just about every RAM module manufacture makes wide temperature range industrial modules. Micron rates their from -40C to 95C.
