I have always wondered exactly this.
Market segmentation on what platforms/controllers support ECC: fine, whatever. But market segmentation of what is an “ECC DIMM” vs. a “regular DIMM”? It makes no sense that the commodity memory manufacturers have any leverage to enforce that segmentation.
Is it just laziness on the part of the platform vendors (who do have leverage) not simply allow ECC with any DIMMs by giving over 1/k {bits, lines, pages, chips, whatever-granularity-they-reason-about} to parity?
- acdha 4y agoIt’s not the memory providers but the chipset manufacturers like Intel pushing customers to the expensive workstation/server lineups.
- sliken 4y agoOn the Intel side, yes. On the AMD side, no. However Intel guarantees ECC will work on their "workstation" chipsets. AMD doesn't guarantee ECC will work on their desktop/workstation chipsets. You have to go up to Epyc to find a guaranteed/tested ECC.
