Can 2 x 256 RAM and 1 x 512 continue to form a dual channel?

Can't ha. The P965 MCH supports 533 800 1066MHz FSB, is designed with a Core2 Extreme Core 2 Duo Core 2 Solo processor, and is backward compatible with Pentium 4 Pentium D Pentium X, it contains a dual-channel DDR2 SDRAM memory controller, theoretically supports up to 8GB of memory, including DDR2-533 667 800 specifications, but does not support ECC modules. These memory specifications are in fact implemented in a fixed proportion of the external frequency operation of the memory CPU, which is supported by P965 MCH

The P965 MCH accelerates memory access with Intel Fast Memory Access technology, which includes the following components:

Just in Time Command Scheduling -- Allows for safe, efficient overlapping of instructions in the memory bus by monitoring all actions that are not allowed access.

Out of Order Execution -- Monitors system memory pending requests, allowing skipping records to make better use of open memory pages to reduce latency and increase bandwidth.

opportunistic writes -- Monitors system requests and makes pending requests when memory is free, making memory data flow more efficient.

Clock Crossing Optimizations -- Ensures that data is transmitted efficiently between the two frequency domains in the first available clock phase.

These technical points can optimize the data transfer efficiency between the MCH and the system memory and reduce the latency, this technology usually requires higher memory modules, and higher quality and low rank memory modules are easier to implement and stable. The MCH continues to support Intel Flex Memory Technology, which allows computers to maintain dual-channel operation while using memory modules of different capacities, allowing for more flexibility in system configuration upgrades.

Intel allows 2 memory groups of different capacities to be dual-channel, but never allows 3 strip groups to be dual-channel.

No, you can't! You can also consider buying two 512 ones!

What is said downstairs is real and useful! Admire!

Is it better to have 4 identical 256 memory or 2 identical 256 + a 512, which scheme is better?

Ideas can be made, but they are not easy to implement!

You can find exactly the same 256 memory, but there is no guarantee that the intrinsic quality will be the same, so your ideas will be disappointed. Even if it succeeds, the compatibility problem will find you later! Besides, does your machine have 4 sockets?

2. The second plan, I advise you not to use it, because it will not succeed at all!

Again, buy 256 and sell two 512 ones!

Don't think that if you say less, you won't care! Whatever you !!

Dude, this is not going to work! Don't listen to what they say, a lot of content is useless! It's all copied!

Remember, the "double" of the double channel! It refers to "two" of the same frequency, the same brand of memory to form a dual channel!

Of course you can't do it with three memories now!

Your two options! 4 identical 256 memory, this scheme is good! Also the most practical。。 But it must be, the same brand, the same specifications!

The continuation of the 256 is dual-channel

and 512's to their own care.

A single 4G memory should be DDR2 or DDR3, but your other 512M and 256M are not, right? Potato imitation.

Supplement the memory frequency, add the motherboard model, at a glance, and help you take a look.

This depends on how many generations your memory is, 512M should be one generation, oh, at that time, the concept of dual channels has not yet come out.

It is recommended to use two 1GB memory graphics card LSDs, which is quite good.
