How is the memory clock frequency of the motherboard that has just been replaced?

The actual clock frequency and effective clock frequency of the memory are determined by both the CPU frequency and the front-side bus PCI frequency.

Your DRAM:FSB ratio is 4:5

From your CPU and FSB frequency, an effective frequency of 322 MHz is no problem. You can set the memory CAS delay, RAS to CAS delay, RAS pressurization, and TRAS via the motherboard BIOS(These are the spds of memory).

Generally, there will be two types of SPDs that have been set up, 1T and 2T, and you can also apply them directly. In your memory clock:

200 mhz (cl-rcd-rp-ras)

166 mhz (cl-rcd-rp-ras)

133 mhz (cl-rcd-rp-ras)

Roughly speaking, your memory is working in the second mode, and you can go into the motherboard BIOS to change it yourself.

Hello! First of all, it's obvious that you're two 512M sticks, are you sure that both are DDR400 memory sticks? So obviously, the external frequency of the motherboard is so large, and it can't support the external frequency of your large memory, and then ask you, such an old machine.

What do you care about, if you have any external frequency, you might as well change to a new machine, the speed of 322 and 400 is basically no different, and it doesn't make sense for you to make a big deal of trouble on the old machine! Go directly to the seller of the board and tell him to change the BIOS so you only have overclocking, I don't know what you have, Jinbang's words, there should be no problem.

There's nothing wrong with it, and you haven't been hacked either.

Tear it down! There is a label on it.

DDR400 is also DDR333 to use, the motherboard is default, and you have to set it in your BIOS. You can manually adjust your memory voltage or something, 512's can be optimized very well, but you have to go back to the settings, and if the settings are not good, it will be inversely proportional.

Generally, the default memory frequency of the motherboard after 05 is DDR400, but if your board is DDR333, the 400 will only be reduced to 333, and there is generally no compatibility problem.

Limit. The master version determines what kind of memory you use.

Yes, you can use it, if you don't support it, it's just that the motherboard will automatically reduce the frequency of the memory, and you can check the specific parameters of your board on the Internet.

The frequency is a range-limited. So you can use.

Let me be brief.

The CPU can be overclocked!

In the BIOS there is a ratio of CPU external frequency to memory frequency, up to 1 2The assumption here is 1 2

When the CPU external frequency exceeds 300, the memory needs to be 1200. When it exceeds 400, the memory will be 1600. When the CPU is super high, the memory frequency will naturally be higher.

Now there are no 1333 1600 memory sold on the market.

So that's what the ratio is used to adjust that.

After 533, it is DDR2 memory, which is not plugged into the previous board, if 533 and 667 are plugged into the motherboard together, the main frequency of 667 is used at 533.

That's what technology is now. It is not upwardly compatible, only backwards. The 400 and 667 are used together, and there is only a frequency of 400. Generally speaking, motherboards are generally more compatible upwards because they have been considered for future upgrades when they come out.

The main frequency of the CPU refers to the actual operating frequency of the CPU core, that is, the clock frequency of the CPU. The external frequency of the CPU refers to the base clock frequency provided to the CPU by the motherboard. The frequency multiplier refers to the multiple between the main frequency of the CPU and the external frequency.

The operating frequency of a memory is the reciprocal of its clock cycle.

What is the external frequency of the motherboard? Is it the external frequency of the CPU? The motherboard you are talking about should be the system bus, and the CPU external frequency is the same as the actual frequency of the memory, but some hosts can do memory asynchronous, that is, the frequency of the memory is different from the frequency of the CPU, which can be high or low.

945 motherboard machine.

You can use DDR2-533 and DDR2-667 memory, and the strip you are currently using is DDR2-667.

So add a DDR2-667 to open dual-channel memory, and the clock frequency multiplied by 2 is the nominal frequency of your memory.

If you look at the CPU-Z, it must be PC5300

You're going to change anyway! If you take the time to go directly to the computer mall and ask a few more stores, won't you know?

Is this it? HP Compaq NX6320 (GC875PA) Processor Type: Intel Core Duo

Processor model: Intel Core Duo T2300E Processor frequency: (GHz).

L2 Cache (KB): 2048

System bus frequency: 667

Centrino Technology: Centrino 3rd Generation.

Motherboard chipset: Intel 945GM

Standard memory capacity (MB): 512

Memory type: DDR2

Extended memory capacity (MB): 4096

Look at the memory that can support up to 667, rest assured to change it, it can support up to 4G memory.
