Wondering how DDR3 and DDR4 compare? We explore the main differences between DDR3 versus DDR4 RAM, including speed, price, and the future of DDR5 RAM.
DDR4 is not backward-compatible with DDR3 so a DDR4 DIMM will not fit on a DDR3 DIMM slot. Not only is the key notch of each DDR generation different (please refer to Figure 1 above), but the DDR4 pin size and arrangement is different from DDR3.
Physically, a DDR4 module, looks very similar to a DDR3. However, DDR4 has 288 pins compared with DDR3’s 240 pins; DDR4 SO-DIMMS have 260 pins instead of 204 in DDR3.
