Samsung Rings B-Die Memory Death Knell

Overclockers love Samsung's B-Die memory, but the company is unceremoniously killing it off. According to the consumer DIMM section of Samsung’s latest Product Guide, B-Die memory "dies," M-Die matures, A-Die ascends, and 32GB UDIMMs really are available in Q2 2019.

We’ve yet to see whether A-die chips will have the overclocking flexibility to match or exceed that of the current B-Die products that have become the memory of choice for overclockers on Intel and AMD platforms alike. 

The new A-Die offers the advantage of higher available chip density, particularly to module assemblers/programmers (i.e., the companies we’re accustomed to supplying our XMP-rated DIMMs). The 16Gb (sixteen gigabit) M-Die chips that were supposed to have brought us 32GB consumer DIMMs a year ago appear to have been reserved for Samsung’s own-brand modules, and the best guess from our suppliers has been that the server sector has drawn that supply dry.

SuperBiiz lists part number M378A4G43MB1 as a current, out of stock product, and with no customer reviews…ever. The additional A-Die part number M378A4G43AB1 could potentially increase supply, but only if that increased supply can finally meet the company’s higher-market obligations.
