DDR4 compatible with DDR3? Can the DDR3 motherboard use DDR4 memory?

2016 can be said to be the first year of DDR4 memory, with lower power consumption, stronger performance DDR4 full listing, coupled with the price and DDR3 difference, the new installed user preferred DDR4. However, for some computer users, the old computer can upgrade DDR4 memory, DDR4 compatible DDR3? The key question here is whether the DDR3 motherboard can use DDR4 memory, here is a small series for you to explain in detail.

　　Q:DDR4 compatible with DDR3?

A: The answer is no, because the DDR4 memory strip appearance changes obviously, the memory of the gold fingers into a curved, shape and interface are changed, from this point can be clearly known, DDR4 memory incompatible DDR3.

All along, the memory of the gold fingers are linear, DDR3, DDR2 are so, and in the latest DDR4 this generation, the memory of the golden finger has changed markedly, the gold fingers become curved, as for why complete, the reason is as follows.

The gold fingers of the DDR4 memory reach 284, each of which is reduced from 1mm of DDR3 memory to 0.85mm (the previous generation DDR3 memory Gold finger contacts are 240), which causes DDR4 to design the lower part of the memory as a slightly protruding, marginal shape in the middle, At the center of the high and lower ends of the low point of the smooth curve transition, which formed a bending effect, and the gold finger between the "gap" is the position of the DDR3 is closer to the center than the hole.

　　Can the Q:DDR3 motherboard use DDR4 memory?

A: From the above analysis can be seen, because DDR4 memory incompatible DDR3, which led to some of the previous motherboard platform incompatible DDR4 memory, so DDR3 motherboard can no longer use DDR3 memory, for some old platform upgrade users need special attention, the old computer upgrade memory, can not buy DDR4, Otherwise, an incompatible, unusable phenomenon can occur.

　　DDR4 compatible with what CPU and motherboard?

Since the old platform can not be compatible with DDR4 memory, then what kind of computer can use it? The answer is DDR4 memory is compatible with the new CPU and motherboard only.

Intel platform, currently only six generation of CPU support DDR4, such as i3 6100/6300 i5 6500, and so on, mainstream six generations of CPU support DDR4 memory.

AMD platform, there is no one of the AMD processor support DDR4 memory, but AMD will be released this year AM4 interface new CPU will fully support DDR4 memory.

Motherboard, currently only six generation motherboards, Intel's 100 series motherboards, such as B150, Z170 motherboards support DDR4 memory, AMD platform needs to wait until the new AM4 interface motherboard to support DDR4 memory.

It is also worth mentioning that the new getting started motherboard may not support DDR4 memory, such as the low price primer B150 motherboard Some do not support DDR4, which you need to pay attention.
