Asus H81M-K review: 33 facts and highlights

1. RAM speed

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

2. 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.

3. 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.

4. maximum memory size

The maximum amount of memory (RAM) supported.
16GB
Asus Z10PE-D16 WS: 1024GB

5. 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.

6. 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.

7. 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.
