Asus Z77-A review: 36 facts and highlights

1. RAM speed

It can support faster memory, which will give quicker system performance.
1600MHz
MSI X299 Raider: 3466MHz

2. overclocked RAM speed

The motherboard supports overclocking the RAM to a higher speed. By increasing the speed at which the memory runs, you can boost the performance of your computer.
2400MHz
ASRock X299 OC Formula: 4600MHz

3. Signal-to-Noise ratio (DAC)

When an audio chipset converts a digital audio signal to an analogue one (for example when playing an MP3 on your speakers), a certain amount of noise is added. A higher SNR means that there is less added noise and the audio quality is better.
110dB
Gigabyte Aorus X299 Gaming 9: 127dB

4. maximum memory size

The maximum amount of memory (RAM) supported.
32GB
Asus Z10PE-D16 WS: 1024GB

5. SATA 3 connectors

SATA is an interface used to connect mass storage devices such as hard drives and Blu-ray drives. SATA 3 has a native transfer rate of 6 Gbit/s, which is twice as fast as SATA 2, the previous revision. This is particularly useful if you use an SSD as it can perform at higher speeds.

6. memory slots

More memory slots (also known as DIMM slots) allow you to add more RAM to your computer. It is also useful when upgrading, as you can add RAM to an empty slot instead of replacing an existing memory module.

8. PCIe 3.0 x16 slots

PCIe slots allow you to connect peripherals to the motherboard, most commonly graphics cards but also others such as sound cards and network cards. The ‘x16’ represents the number of lanes it has, with more lanes supporting higher data transfer rates. PCIe 3.0 offers higher transfer rates than PCIe 2.0, and can give increased performance.

9. fan headers

Fan headers are connection points on the motherboard that cooling fans can be connected to. Fans can also be connected straight to the power supply, but when connected to the motherboard you gain much finer control over them through software.

10. Supports RAID 1

RAID is a storage technology that combines multiple disks into one unit. RAID 1 mirrors the data across the drives. This gives you greater data security as if one drive fails, the data will still be accessible from another.

11. USB 3.0 ports (through expansion)

The motherboard has USB 3.0 headers, which are pin connections that you can connect additional USB ports to.

12. USB 2.0 ports (through expansion)

The motherboard has USB 2.0 headers, which are pin connections that you can connect additional USB ports to.

13. PCIe 2.0 x16 slots

PCIe slots allow you to connect peripherals to the motherboard, most commonly graphics cards but also others such as sound cards and network cards. The ‘x16’ represents the number of lanes it has, with more lanes supporting higher data transfer rates.

14. height

213mm
Asus Tinker Board: 53.3mm

15. memory channels

More memory channels increases the speed of data transfer between the memory and the CPU.

16. Supports USB charging boost

This feature allows you to charge your devices (such as smartphones and tablets) faster than a regular USB port. Some implementations also let you charge through the USB port even when the computer is in sleep mode or off.

17. Supports RAID 5

RAID is a storage technology that combines multiple disks into one unit. RAID 5 stripes the data across the drives, giving increased performance compared to a single disk. It also provides greater data security as if one drive fails, the data will still be accessible from another due to the use of parity.

18. USB 3.0 ports

More USB 3.0 ports allow you to connect more devices to your computer that support USB 3.0. USB 3.0 is an improved version of USB 2.0 which offers faster transfer rates.

Asus Z87-Pro: 14

19. RJ45 ports

RJ-45 ports are used for LAN (Local Area Network) connections. With more ports you can achieve increased bandwidth across a LAN, or connect to multiple networks. It also has the added benefit of not losing connection to the network if one fails.
