When I upgrade my desktop with this new motherboard, there are some upgrade for whole system.

Let me list these news below:

  • DDR3 to DDR4
  • USB 2.0 to USB 3.1
  • PCIE Gen.2 to PCIE 3.0

The new technoligy brings more features.

DDR3 vs DDR4

DDR4  operates at a lower voltage than DDR3. DDR4 runs at 1.2 volts, down from 1.5 volts. It means to reduce your bill.

DDR3  specifications started at 800 MT/s (or Millions fo transfers per second) and some went as high as 2133. DDR4, meanwhile, starts at 2133 MHz. The increased speed means an overall increase in bandwidth.

DDR3 is 240 pins. DDR4 is 288 pins.


SATA II known as SATA 3Gb/s, is a second generation SATA interface running at 3.0 Gb/s. The bandwidth throughput , which is supported by the interface, is up to 300MB/s.

SATA III known as SATA 6Gb/s, is a third generation SATA interface running at 6.0 Gb/s. The bandwidth thoroughput, which is supported by the interface, is up to 600MB/s.

For me, it will let my SSD reach more higher write / read speed rates.

USB 2.0 VS USB 3.0

The SATA II and SATA III cable and connectors are same.


USB 2.0 vs USB 3.1

USB 3.0 is 10 times faster than USB 2.0, about 4.8Gbps. USB 3.1 gen.2 provides higher data transfer speeds of up to 10Gbps. USB 3.1 offers an “always right” type-C connector, and the capacity to power any type of device.

PCIE Gen.2 vs PCIE Gen.3

In short, PCIE Gen.3 is almost double the speed of PCIE 2.
