Performance will decrease if four memory sticks are inserted

Why is it not recommended to insert 4 sticks of memory into z690

In terms of power consumption. Asus z690mplusd4 memory overclocking plugs in four memory sticks because it needs to drive four memory sticks, so the power consumption is a little higher than that of two memory sticks. In terms of stability.

There will be two colors on the memory slots on the motherboard. Those of the same color form a set of dual channels. Just plug the memory stick into the same color position. Dual channels must be two sets of memory with the same capacity and speed. If the frequencies are different, they will run at the lowest frequency.

It is not recommended to use 4 memory sticks because compatibility issues may occur. Mixing memory modules of different brands, capacities, and speeds may cause compatibility issues.

It is not recommended to use 4 memory sticks: If the motherboard only supports dual-channel memory, theoretically there will not be much difference in performance if the motherboard is plugged into four 8G memory and two 16G memory. After all, they are all 32G dual-channel. memory, but in actual applications the performance of two 16G memories is slightly higher.

The frequency decreases when four ddr5 channels are inserted

To put it simply, Ryzen 7000 still supports dual-channel DDR5 memory, but when two memory channels are installed on the same channel, the memory frequency will be reduced to DDR5-3600 , if 4 memory sticks are inserted (essentially 2 memory sticks under a single channel), the speed will also be reduced to DDR5-3600.

Dual-channel can only increase the bandwidth of the memory, but cannot increase the memory frequency. The memory frequency is increased by overclocking. Therefore, the frequency of four DDR5-5600s together is still 5600MHz. The theoretical memory bandwidth of DDR5-5600 is 48 GBs, and the bandwidth of dual-channel memory is 48x2=86GBs.

The reason why the memory frequency cannot increase: strong① Since the CPU has its own memory controller, the memory first runs at the frequency supported by the CPU memory controller (common frequencies are 2132400, 2662933 and 3200).

Why is it not recommended to use 4 memory sticks

1. It is not recommended to use 4 memory sticks: If the motherboard only supports dual-channel memory, theoretically the motherboard can be plugged into four 8G memory and two There is not much difference in performance between 16G memories. After all, they are all 32G dual-channel memories. However, in actual applications, the performance of two 16G memories is slightly higher.

2. It is not recommended to use 4 memory modules. However, if four memories are inserted, the wire lengths of the 3-channel and 4-channel will be different, resulting in different electrical characteristics between them, which can easily lead to compatibility issues. Specifically, after turning on XMP, the computer cannot be turned on and can only run at low frequency.

3. The reason why it is not recommended to insert 4 memory sticks in Z690 is that it affects performance, data transmission bottleneck, memory stability, insufficient memory space and other issues. Impact on performance: When using four memory sticks, due to more interactions between memories, frequent data exchange between memories will reduce memory performance.

4. The reason why z790 does not recommend 4 memory modules is that it will cause compatibility errors. It is recommended to use 2 memory sticks because this can more effectively utilize the memory slots on the motherboard and improve memory compatibility and stability. At the same time, it can also avoid compatibility problems caused by too many memory banks.

5. In the actual test, the performance of installing two 16G memory sticks to form a 32G dual-channel memory is slightly higher than that of four 8G memories. This is mainly because increasing the number of memory sticks will not increase the bandwidth of the memory. , but it will slightly increase the load on the CPU, resulting in a slight decrease in the performance of the CPU and memory.

6. No. If 4 DDR5 memories are inserted, the compatibility will be a bit poor. The CPU memory channel has been determined during the CPU design and cannot be changed. It is what the industry often calls Channel, whether it is 2 channels or 4 channels. The CPU specifications and motherboard design have already been determined.

How about the fifth generation double data rate dual in-line memory module

A number in a circle indicates the performance level of the memory card. What about the fifth-generation double data rate dual in-line memory module? How about the fifth-generation double data rate dual in-line memory module? Single in-line memory module: When printed on the substrate, the package is in an upright shape.

, different products DIMM: Dual inline memory module is a new type of memory module that appeared after the introduction of Pentium CPU. It provides a 64-bit data channel. SO-DIMM: Small series of dual memory modules are computer memories using integrated circuits.

Refers to different DIMMs: dual in-line memory modules, which refer to the new memory modules that appeared after the introduction of Pentium CPU, providing a 64-bit data channel. SO-DIMM: Small Outline Dual Inline Memory Module, a type of computer memory using integrated circuits.

Single in-line memory module: When printed on the substrate, the package is in an upright shape. A variation of this form is the zigzag in-line package (ZIP), in which the pins still protrude from one side of the package but are arranged in a zigzag pattern.

DIMM (Dual Inline Memory Module, Dual Inline Memory Module) is quite similar to SIMM. The only difference is that the two ends of the gold finger of DIMM are not interconnected like SIMM. They transmit signals independently, so they can Meet the transmission needs of more data signals.
