Anandtech published ASRock Rack Announces EP2C612D24 and 4L: Dual Socket Haswell-EP with 24 DDR4 Slots
A quote from the article:
Two things jumped out at me when I received this press release. Firstly the name, which comes out as a mouthful ? it isn't something you could casually mention in conversation, even if you worked closely with the motherboard. The second is the amount of DRAM slots, which is ultimately what the EP2C612D24 and EP2C612D24-4L are catering for.ASRock Rack Announces EP2C612D24 and 4L: Dual Socket Haswell-EP with 24 DDR4 Slots @ Anandtech
The Haswell-EP/Xeon E5 v3 DDR4 memory controllers are designed for up to three DIMMs per channel, similarly to Ivy Bridge-EP (E5 v2) and Sandy Bridge-EP (E5), although in all cases it is usually reserved for more niche systems. With 16GB UDIMMs, this allows for a maximum of 384GB, although moving up to RDIMM, LRDIMMs or 64GB NVDIMMs pushes the max to 1.5TB in a dual socket motherboard. Only those with deep pockets, big budgets or stringent requirements need apply, as the major cost here will be the DRAM.
