Will ddr4 burn when plugged into ddr3 motherboard?

Ddr4 will not burn when plugged into ddr3 motherboard, because it can't be plugged in at all.

The golden finger part of ddr4 memory has been obviously changed into an arc, and the shape and interface have also changed, so it is not compatible. The golden fingers of ddr3, ddr2, ddr 1 memory are all linear, but for the new generation of ddr4 memory, the manufacturer has made some changes and the golden fingers have been bent.

There are 240 gold finger contacts in ddr3, and the distance between each contact is 0. 1mm, while there are 284 gold finger contacts in ddr4, and the distance becomes 0.85 mm The lower part of ddr4 memory becomes a slightly convex design with short edges, and the high point in the middle and the low points at both ends smoothly curve and finally form a bending effect. The "notch" in the middle of the gold finger, that is, the foolproof opening, is closer to the center.

DDR4 memory specification

DDR4 memory will have two specifications. Among them, the transmission rate of DDR4 memory with single-ended signaling signal has been determined as 1.6 ~ 3.2 Gbps, while the transmission rate of DDR4 memory based on differential signaling technology will reach 6.4Gbps. Because it is basically impossible to realize two interfaces through one DRAM, DDR4 memory will have two specifications based on traditional se signal and differential signal.
