Despite product mix adjustments, suppliers had trouble meeting the various growing demands of the DRAM market, said DRAMeXchange, a unit of market research firm TrendForce that tracks memory chip pricing.

DRAMeXchange analyst Mark Liu said that thanks to the increase in the average memory density of server systems, as evidenced by the adoption of high-density 32GB RDIMMs and 64GB LRDIMMs in this year’s first half, the profit margin of server DRAM surged.

DRAMeXchange said it expects the penetration rate of DDR4 2666MHz modules to rise in the second half of this year due to the introduction of servers based on Intel's Purley platform.

Samsung, the leading memory supplier and the leader in server DRAM market share, saw its second quarter server DRAM revenue rise by 36.5 percent sequentially to reach nearly $2 billion, DRAMeXchange said. Samsung continues to benefit from a commanding lead in the overall DRAM market and an overall lead in manufacturing technology.
