FAQ

The memory voltage is formulated in accordance with the JEDEC standard. The memory specifications formulated by each memory brand will match the voltage according to the memory clock frequency to give full play to the best performance of the memory. If it is used by overclocking players, the best performance can be sought by adjusting the BIOS parameters of the motherboard. (The overclocking performance varies according to individually-matched hardware and parameters.)

Serial presence detect (abbreviated as SPD) is a standardized way of accessing information related to memory modules, such as module related timing parameters, manufacturer, serial number and other useful information. Devices utilizing memory can read the said information to automatically determine key parameters of the module.

CAS latency, referred to as CL value, means how long the computer needs to wait to read the data of the memory before it can actually start reading. The higher the CL value is, the longer the required delay time is and usually it will increase, accompanied with the increase of frequency, and the pursuit of a lower CL is not the best choice. For example, CL2 refers to the time that the memory needs two clocks to access data. Generally speaking, the smaller the CL value is, the more advanced the process used is, and relatively the higher the requirements for the motherboard are.

When ECC memory is used on a motherboard that does not support ECC, theoretically the motherboard will turn off its ECC function and operate as a non-ECC memory. However, if it is used on a motherboard with poor compatibility, the said motherboard may become unstable or unable to boot, and so on.

※ Note: For the applicability of ECC memory, it is recommended to refer to the motherboard specifications.

Rank refers to the memory particle chip connected to the same CS (Chip Select). The memory controller can perform reading and writing operation in the chip of the same rank, and the chips of the same rank also share the same control signal. In terms of the current computer, because the width of a group of channels is 64bit, it can read and write 8byte data at the same time. In case of a memory controller and ECC memory module with ECC function, the width of a group of channels is 72bit .

Rank will be judged subject to the specifications of the memory controller and memory particles, rather than to the number of chips or the single and double sides of the memory module. At present, most of the memory controller channels of home PCs are wide in 64bit, while the memory particles are wide in 8bit. Therefore 8 parallel connections, that is, one group of ranks, can meet the requirements of the memory controller. However, occasionally there are memory modules made of 16bit-wide memory particles. At this time, one group of ranks consists of 4 chips.

Have you ever encountered installing or boot issue while using the memory? Do you know how to use the memory correctly?
Let's introduce the simple memory debugging process now!

1.  Installation method

I. The correct hand position for installing the memory can ensure the force on the gold contacts of the memory is even to avoid damage.

II. When installing the memory, make sure there's no dust or foreign objects on the gold contacts of the memory and the motherboard slots. Foreign objects or dander might easily burn the memory.

2. PC won't boot (Cannot enter BIOS)

I. First, refer to the order of the motherboard memory slot. → Install the memory (single or dual channel) in the correct memory slots of the motherboard. → Check if it can boot normally.

> dual channel   > single channel

The memory slots of each brand of the motherboard have a custom order. Please refer to the manual of the motherboard.

II.  If already installed in the correct position but still can't boot. → Install a single memory in a slot of the motherboard in turns for testing. → Find out which memory has a problem. If the problem that the PC is unable to boot has been confirmed, please contact the manufacturer for repair.

III. Cross test to see if there is a problem with the memory slots of the motherboard. → Install the memory that works normally in DIMM1~DIMM4 in turns to see if all DIMM slots are working.

IV. If there's another motherboard available → Install memory on the different motherboard to see if it's working normally. → If it is still not working, it can be inferred that it is caused by the memory.

3. RGB lighting issue

I. If RGB memory's lighting is not working, it is mostly caused by the LED lightbulbs. It should be sent for repair directly.

II. If RGB memory's lighting cannot be controlled, please install and test with only one RGB software, or update RGB software to the latest version. While testing, please make sure other software is completely uninstalled.

III. Please do not use alcohol or eraser to clean gold fingers.
