DDR4 DRAM module beats the heat up to 125℃
DRAM module enables manufacturers to design systems as needed and free of the limitations imposed by noisy fans, large cooling fins, and heat spreaders.

The first-of-its-kind Ultra Temperature DDR4 DRAM module from Innodisk can operate from a chilling -40℃ to a scorching 125℃. The Ultra Temperature format extends the standard industrial-grade maximum temperature. The series brings extra features to the table, opens the doors for new industrial applications, and passes multiple strict tests to prove its resilience.

For example, self-driving vehicles must deal with heat-generating intensive computing and data processing in closed installation spaces, especially in SAE level 2 vehicles (and above) that use data-intensive self-adjusting cruising and lane departure. Fanless embedded systems with increasingly compact mechanical designs face internal space constraints that are a big headache for cooling. Mission-critical applications must be reliable in environments that are often inhospitable to electronics where temperature issues can hinder the effectiveness of detecting and identifying objects.

The Ultra Temperature series offers 3200 MT/s high speed and is available in SODIMM and ECC SODIMM with 16 GB and 32 GB capacity. Besides, value-added extras toughen DRAM and give maximum resilience in any industry. Firstly, a robust 45 micro-inch gold finger provides a tougher, more reliable connection than the typical 30 micro-inch gold finger found on most industrial-grade DRAM. There’s also side fill technology that protects and strengthens delicate solder joints against thermal and mechanical stress. Anti-sulfuration is an additional protective layer on vulnerable parts, protecting them against silver alloy corrosion caused by sulfur. Finally, there’s a built-in thermal sensor that accurately measures and tracks component temperature.
