Innodisk industrial-grade DDR5 DRAM modules

Innodisk has released its industrial-grade DDR5 DRAM modules. The DDR5 specification is said to detail up to four times as much capacity per IC, raising the maximum achievable per die capacity to 64 GB and bringing the maximum potential capacity for a single DDR5 DIMM to 128 GB.

DDR5 has a theoretical maximum transfer speed of 6400 MT/s, doubling the rate of DDR4. Meanwhile, the voltage has been dropped from 1.2 to 1.1 V, reducing overall power consumption. A further major structural change is power management is moved onto the DIMM, reducing redundant power management circuitry on the motherboard for unused DIMM slots.

Another structural change is dual-channel DIMM architecture. For DDR5, each DIMM has two 40-bit channels (32 data bits, eight ECC bits each) for the same data total with more ECC bits. Two smaller independent channels are designed to improve memory access efficiency, leading to greater speeds with higher efficiency.

Innodisk currently offers DDR5 up to 32 GB and 4800 MT/s.
