RAM memory modules from DDR2 to DDR5 –
An overview of sales shares

The demands on memory have changed significantly in recent years. While older technologies such as DDR1, EDO, Fastpage, or SDRAM are hardly in demand in our RAM online shop, modern memory solutions such as DDR4 and DDR5 dominate the market. Our sales statistics for 2024 clearly show which memory technologies are currently preferred.

RAM technology sales shares in 2024

  • DDR4 RAM remains the most important memory technology with a market share of 65.75%, showing almost constant demand (2022: 65.52%).
  • DDR3 RAM saw a decline of over 5% and now reaches 25.65% (2022: 30.75%).
  • DDR5 RAM is gaining significant popularity. Rising to 7.44% (2022: 2.19%), this technology now ranks third.
  • DDR2 RAM, now rarely used, accounts for just 1.13% (2022: 1.53%).

Older RAM generations such as DDR1, EDO, Fastpage, and SDRAM are no longer relevant in our statistics as demand has virtually dropped to zero.
