Industry needs availability on a wide range of servers
When 32GB HCDIMMs become available, they will be the memory module of choice in the 32GB segment.
This will be applicable to both the regular Romley servers as well as the non-Intel-POR (plan-of-record) servers like the IBM x3750 M4 server.
The reason is that:
– HCDIMMs are RDIMM-compatible
– HCDIMMs run at higher speed than LRDIMMs
– HCDIMMs outperform LRDIMMs in latency and throughput even when HCDIMMs are run at the lower same speeds as LRDIMM
Their qualification on a wide range of servers is essential for the industry to get access to the best memory available.
Marketability as a better RDIMM
UPDATE: 07/09/2012 – buyout
UPDATE: 07/09/2012 – strategic value of RDIMM-compatibility and misconceptions debunked
UPDATE: 07/27/2012 – confirmed HCDIMM similar latency as RDIMMs
UPDATE: 07/27/2012 – confirmed LRDIMM latency and throughput weakness
Is Netlist a buyout candidate ?
Is LRDIMM a dead-end product ?
Is it easier to market a better RDIMM that includes all the features of an LRDIMM ?
The primacy of load reduction and rank multiplication for 32GB
UPDATE: added 07/06/2012: Netlist on 8Gbit DRAM die non-availability
UPDATE: added 07/06/2012: Inphi on 8Gbit DRAM die non-availability
32GB RDIMMs are all 4-rank (quad-rank).
4-rank creates a high memory load on the memory bus.
