Samsung has developed the world's first 128 GB DDR4 registered memory modules for servers. From the press release:

Following Samsung's introduction of the world-first 3D TSV DDR4 DRAM (64GB) in 2014, the company's new TSV registered dual inline memory module (RDIMM) marks another breakthrough that opens the door for ultra-high capacity memory at the enterprise level. Samsung's new TSV DRAM module boasts the largest capacity and the highest energy efficiency of any DRAM modules today, while operating at high speed and demonstrating excellent reliability.

From The Register:

The Register is aware of servers with 96 DIMM slots, which means ... WOAH! ... 12.2 terabytes of RAM in a single server if you buy Samsung's new babies.

Samsung says these new DIMMS are special because "the chip dies are ground down to a few dozen micrometers, pierced with hundreds of fine holes and vertically connected by electrodes passing through the holes, allowing for a significant boost in signal transmission."

There's also "a special design through which the master chip of each 4GB package embeds the data buffer function to optimise module performance and power consumption."

    So when can I buy a motherboard for a desktop machine that will take these?

    And before you ask I love playing with Blender 3D

    In fact what is the most memory you can get on self build desktop at the moment?

    I remember looking a good few years ago and all the motherboards had weird restrictions either on the total size per module or the number of modules.

    You know, these are trivial to investigate. You can easily get 64GB on a desktop these days. 8GBx8.

    AMD: 64GB

    Intel: 128GB

    And these are cheap options too. And what is the problem with Blender? Do you honestly need more than this for your typical work?

      Doesn't seem like those support ECC. Who would use 64GB+ of non-ECC memory?
