What CPU only supports 2 with memory

It has nothing to do with the CPU.

It's going to look at the main version of Intel's.

845 865 915 is DDR, but some 915s are DDR2.

Including the 945 main version that supports dual cores, there are also a small number of those that support DDR.

There are miscellaneous brands on the market that support DDR and DDR2 memory, but they are not used at the same time, but only one can be selected, because the memory specifications are different, and they cannot be used at the same time.

Generally, it is available on the main version of the box or manual.

Since it is not impossible for you to judge by CPU, except for a few special ones, the CPU that generally uses the 478 interface uses DDR, and the CPU with the 775 interface is DDR2.

There is another way that I think is very suitable for you, that is, to use a software called cpu-z, you can find it yourself, and you can see the cpu parameters after opening it, and there is a memory option in it, which says what memory you use, and generally the main version can only use one kind of memory, and I said above that there are two kinds of small parts at the same time.

Whether your computer supports one or two generations of memory is not up to the processor.

Whether a computer can have a previous or second generation of memory depends on what chipset motherboard it uses.

As far as the Intel platform is concerned, the current 915P and above support DDR2 model memory.

On the AMD platform, as long as the motherboard supports the AM2 interface, all motherboards support DDR2 memory.

In fact, it is determined by the motherboard, which CPU and what memory the motherboard supports. How much memory can be expanded, how many large hard disks can be supported, etc.

AMD's AM2 interface supports memory controllers in the CPU.

Intel's need to see the host because his memory controller is at Northbridge.

Boards above 915 are supported.

Intel is hard to say, this depends on the motherboard, not the CPU.

AMD's CPU supports DDR2 memory as long as it is an AM2 interface.

2. With memory is Kanban. The number of pins of the board determines the CPU

This is not a CPU! It depends on the motherboard!!

The amount of memory that a CPU can bring depends on the number of bits of the CPU.

bit CPU, the maximum addressing power is 4G. Only 4GB of RAM can be brought.

Bit CPU, theoretically with 16EB of flash memory. But in Windows systems, up to 192GB of memory can be recognized.

The CPU must be imitated and must be used with a 64-bit system.

4. Ordinary home motherboards can generally only install up to 32G of memory. If you need more memory, you must use a workstation-class, server-class motherboard.
