The DDR4 memory market has experienced significant turbulence over the past month, as major manufacturers discontinue older production lines. This shift has triggered a surge in speculative purchasing, resulting in unprecedented price escalations. Spot prices for DDR4 8Gb (1Gx8) modules have risen by more than 80%, while DDR4 16Gb (2Gx8) chips are now trading at a premium exceeding 40% compared to similarly sized DDR5 units.
