Key points to note on these 715166-B21 HPE 32GB (1x32GB) Dual Rank x4 PC3-10600H (DDR3-1333) HyperCloud CAS-9 Memory Modules:-

• :: HyperCloud is plug and play and requires no BIOS updates of the motherboard (demonstrated on pre-Romley systems).
• :: 32GB RDIMMs are only available in 4-ranks (because 2-rank requires 8Gbit DRAM die which will not be available for a few years) and 4-rank suffers abysmal performance at not just 3 DPC but also 2 DPC and even 1 DPC .
• :: Thus the use for HyperCloud has expanded from 3 DPC at 16GB – to 3 DPC and 2 DPC and possibly even 1 DPC at 32GB memory module levels.
• :: In the future, HyperCloud (currently being copied in LRDIMMs) will be licensed for DDR4 – as DDR4 copies the load reduction and rank multiplication features that LRDIMM has taken from HyperCloud, but will also incorporate the symmetrical lines and distributed buffer chipset on the HyperCloud.
• :: Therefore HyperCloud is essentially a smooth continuation onto DDR4, while LRDIMMs are “end-of-life” with their asymmetrical lines (cause of the latency issues) and centralized buffer chipset.
