What is the difference between a 512M DDR400 dual channel bar and a 512M DDR400 bar?

1: You misunderstand the meaning of dual-channel, the memory itself is not divided into dual-channel single-channel, as long as you have the same capacity and frequency (that is, they all have to be DDR400, or 333, 266, etc.), plug the two memories into the slots of different colors of the motherboard (provided that your motherboard must support dual-channel, remember) You can automatically form a dual-channel.

2: You don't have to DDR400, depending on how much DDR your motherboard supports (it's best to report the motherboard model).

3: The latency is 2 now, or you don't need to care about it.

You said that you can find that the memory is divided into single and dual channels on the Internet.,That's a gimmick of the manufacturer.。。。

In fact, the second can be understood as better memory parameter consistency, or the other way around, the former parameter is too bad.

In fact, dual-channel is that the motherboard supports dual-channel walking, not memory Jinbang Platinum Bar 512M DDR400 (dual-channel) means install two Jinbang Platinum Bar 512M DDR400 on the motherboard

If you want to build a dual-channel, it doesn't have to be a DDR400 strip, it can be a DDR800 ah The higher the faster, pay attention to the maximum number of supports your motherboard

The strips are all the same, and there is no dual-channel in itself, and the dual-channel is determined according to your motherboard.

Memory is 1x faster in usage. SDR has a speed of 1x, then DDR has a speed of 2x. Use dual channel speed 4x. There is a formula for calculating the speed of memory.

Dual-channel 512 is 1G.

That's what I do on my computer.

The voltage of DDR2 is lower and the bandwidth is wider.

The frequency is not the same, no.

The principle of dual-channel is that dual-channel memory technology is a memory control and management technology that relies on the function of the chipset's memory controller to theoretically double the bandwidth provided by two memory of the same specification.

The dual-channel system consists of two independent, complementary smart memory controllers that can be operated in parallel. For example, when controller B is ready to make the next memory access, controller A reads and writes to the main memory, and vice versa. This complementary "nature" of the two memory controllers allows the effective wait time to be reduced by 50 percent, so the dual-channel technology doubles the bandwidth of the memory.

Obviously, when the frequencies of the two memories are different, it is impossible to achieve reciprocal complementarity (it can also be said that synchronous transfer cannot be realized: one memory is read, the other memory is written, when the frequencies of the two memories are different, it is not synchronous and will fail).

Please refer to Dual Channel.

The key is to understand the principle.

No, there will be poor compatibility because the frequency is not the same.

Yes, you can run two memory of the same specification at the same time. DDR400 is a generation of memory. 400 is the operating frequency.

Dual-channel memory technology is actually a memory control and management technology that relies on the chipset's memory controller to function, theoretically doubling the bandwidth provided by two memory of the same specification.

You can definitely plug in two.

DDR is a type of memory, like a jeep, and the 400 indicates how often it works, as if the car can go up to 120 km.

The 400 strip is not available now, so there is no need to upgrade. If you want to upgrade, you should upgrade the motherboard directly, the performance is much higher than if you add memory.

Dual-channel DDR support means that two memories can be used at the same time, and DDR400 refers to the bandwidth of DDR memory

Models such as DDR, DDR2, DDR3, SDRAM and the like.

That's it.

DDR400 is a memory model, which belongs to the 1st generation, and it is more expensive to buy now, and the dual-channel is to plug in two identical DDR400s, so that your memory and motherboard CPU interface speed are doubled.

There are a lot of DDR400 1G board memory on the Internet, don't buy it, if you want to buy it, buy regular DDR400 1G memory.

Problem Description: I am asking about the Jinbang Platinum Bar 512M DDR400 (Dual Channel) memory module with.

What is the difference between the memory module of Jinbang Platinum Bar 512M DDR400?

I want to buy two Jinbang Platinum 512M DDR400, there are dual-channel and non-dual-channel strips, I don't know what is the difference between these two strips?

If I want to build a dual channel, it must be a DDR400 (dual channel) sliver, okay?

What is the detailed latency description of the two slivers (e.g. cl=3-8-4-4)? Is the CL equal delay of the dual channel higher than that of ordinary strips? What is the difference between the two types of slivers?

Detailed answers, after adoption, another 50 points will be given.

Analysis: 1: You misunderstand the meaning of dual channel, the memory itself is not divided into two channels and single channels, as long as you have the same capacity and frequency of two memories (that is, they all have to be DDR400, or 333, 266, etc.), insert the two memories into the slots of different colors of the motherboard (provided that your motherboard must support dual channels, remember) You can automatically form a dual channel.

2: You don't have to DDR400, depending on how much DDR your motherboard supports (it's best to report the motherboard model).

3: The latency is 2 now, or you don't need to care about it.
