Can a 1G and a 256 form a dual channel? 10

How is this possible?

Dual-channel must have the same capacity for both memory.

It's better to have a brand, so the compatibility is better.

And you better get rid of the 256.

It's useless, and there will be program memory conflicts if you don't do it.

That's why it's the same reason why you insert a memory stick, either one or two.

Haven't you heard of a 512 with a 256, because that is very incompatible.

There is no need to deliberately pursue dual-channel, although dual-channel composition can improve memory performance by 5%, but the overall performance improvement is less than 1%, Intel can use DDR 800 and DDR 667 to form dual-channel, but DDR 800 will be downclocked to 667 to use, AMD needs the same model to form dual-channel.

Finally, compose a dual-channel to see if your motherboard supports it or not.

No, it's better to use the same model for dual channels, and now there are suits.

No way! Dual-channel can only use 2 memory of the same capacity, and it can be used without a dual-channel, which is fine.

No, this depends on your motherboard's support, if you can, you have to have the same two memory modules.

Now there are asymmetrical dual channels,(865PE doesn't seem to support) But the performance has not improved,What's more, yours is 1G to lose 256M,If you don't have anything, plug it in together.,It's the same without dual channels.,There's not much loss.。

You need both to have the same amount of memory and your motherboard supports dual channels. It's better to be the same brand.

Your 256's should be 333

1g is 533

If both are plugged in, the 533 can only run out of the frequency of 333.

In other words, 256's can throw o(o

It is possible to form asymmetrical dual channels.

Asymmetric dual-channel memory technology allows different capacities, different specifications, and even unpaired memories to form dual-channel, making memory collocation more flexible and making system configuration and memory upgrades more flexible.

For example, the 8GB memory and 2GB memory mentioned in the question implement asymmetric dual channels. The system divides the 8GB channel into two parts: one part and the 2GB channel form a dual channel, while the remaining 6GB still works in single-channel mode, and the capacity and speed are not wasted.

The technology was used on the Intel 915 chipset, and it was not until the 945 955 chipset matured, and the 965 975 chipset optimized it for better performance.

Today's motherboards already support asymmetrical dual-channel memory technology.

No, dual channels must be two memories of the same capacity, frequency, and type, and the only one is brand-agnostic (basically).

The composition of dual channels has the following working modes, depending on the combination of the motherboard and the CPU:

1.Symmetrical dual-channel operation.

The symmetrical dual-channel working mode requires the memory capacity of the two channels to be equal, but there is no strict requirement for the absolute symmetry of the memory capacity, which can be 512MB +512MB for channel A and 1GB for channel B, as long as the total capacity of channel A and channel B is equal. Dual-channel mode is available with 2, 3, or 4 memory modules, depending on the speed of the memory module installed in the system, if the speed of the memory module is different. The details are as follows:

1) Absolute symmetry of memory modules. This is the most ideal symmetrical dual-channel, that is, insert the same capacity of memory sticks in the same color slots, the number of memory modules is 2 or 4, and all the memory in this mode works in dual-channel mode, which has the strongest performance.

2) Symmetry of memory capacity. This mode does not require the same number of memory modules in the two channels, and can be composed of 3 memory channels to form a dual channel, and the total memory capacity of the two channels is equal, and all the memory also works in dual channel mode) The performance is slightly inferior to mode (1).

2.Asymmetrical dual-channel mode.

In asymmetric dual-channel mode, the memory capacity of the two channels can be unequal, and the size of the memory capacity that makes up the dual channel depends on the channel with the smaller capacity. For example, if channel A has 512 MB of memory and channel B has 1 GB of memory, 512 MB in channel A and 512 MB in channel B form dual channels, and the remaining 512 MB memory in channel B still works in single-channel mode. It is important to note that both RAM must be plugged into slots of the same color.

The dual-channel technology Intel architecture is generally determined by the MCH (Northbridge), while the AMD architecture is determined by the CPU.

Theoretically, yes, but in fact no.

What I know so far: No, you have to pair it.
