100 points, upgrade the memory for help,

PC3200 is DDR400 okay. Not DDR200!!

Ordinary DDR400 is sufficient, and the new one has not been discontinued for a long time. Beware of second-hand fakes, server junk. Wait.

Furthermore. Since the gap between 1g and 256 is too large, it is better to unplug the 256 one and 1g alone, which is more stable.

Also, it's better to buy 1G double-sided noodles (DDR400 1G is mostly double-sided, don't buy a few single-sided) compatibility is much better.

Now I don't know if there is any memory for sale or not, and even if there is one for sale, it is not cheap. You can just get a new computer, and now it's not expensive to have a computer

Choose DDR Generation's!

Because PC3200 (200 MHz), DDR333 and above are compatible, it is highly recommended that you take the main chassis to buy, and you have to try it on site!

It's not the brand that matters, it's the compatibility that matters!

You'll want to run a larger game or program live to see if it can run smoothly! That's all that matters!

It is recommended not to change the memory, or to change the board, DDR 1G memory, even if you can buy it, I feel that your board will not work.

Kingston, ADATA, Kingmax.

1g ddr400

About 230 yuan.

It is recommended to upgrade the memory, which is indeed very effective.

Friend: I'm sorry to tell you! DDR 400 and DDR2 technologies are not compatible! Therefore, you can only choose the same DDR 400 memory to upgrade the memory!

As for the memory brand and actual frequency, if not disassembled! It's easy to recommend using CPU-Z, a software to look around! If you want to be more detailed, use everest to check it out!

And here's what I'm going to tell you!

The actual standard frequency of the 2200 is DDR 333 and it is 256M, even with an upgrade of 400 memory! The actual memory frequency is also likely to be DDR 333!So you don't have to consider using DDR 400 memory to upgrade, in fact, 333 is about the same!

2.Generally speaking, there are a maximum of two memory slots in NB! If you already have two 256M RAM in your machine!

That can be said that there is no room for you to upgrade! If you want to upgrade the ruler state, you can only give up one or all of them and buy a new large-capacity memory! You must be clear about this before you upgrade!!

3.From my personal point of view! Your Dell 2200 should be configured with a CM 360 level CPU, although this is still a fast and practical CPU, but Lingzhiyuan is limited after all!

Considering that electronic products are updated quickly, and NB is not very scalable! It is not recommended that you spend any more money on this 2200! After all, judging from the configuration of your whole machine!

Even with a larger memory upgrade! Due to CPU constraints! The performance improvement of the machine is also limited!

Let it start and finish well! Brilliant job done! Spend money on a new one later!

Relatively calculated! everest:

cpu-z:

You can add a memory stick, pay attention to pick the same brand to ensure compatibility.

Memory purchase and socket interface,It's DDR2,DDR3,Your original DDR2 is DDR2,The second is the frequency,Your original is 667,But the general motherboard can support DDR2 800,If it's 2 to change,It is recommended to change 800 directly,If the old 1G is still used,No matter how much you change,It will be automatically downclocked to 667

The memory purchase has the same type and frequency as the memory block.

1.The original memory is DDR2, so the upgraded memory can only use DDR2 memory, which will not be compatible with DDR3 memory, and there is no way to insert memory slots.

2.The original memory is 667 frequency, you need to make sure that the laptop motherboard supports 800Hz memory (because 667 and 800 belong to the same DDR2 series), if not, you can only upgrade to 667Hz.

3.If the system is 32-bit, it would be good to upgrade only one 2G, but this memory can only be DDR2 667, because the 32-bit system memory only supports a little more than 3G, and it is a waste to match more.

If it's a 64-bit system, you can upgrade to 4G memory with confidence.

1. Does it affect the warranty when I open the chassis to upgrade the memory by myself?

The appearance of the factory parts is not damaged without affecting the warranty, and the barcode of the spare parts is not allowed to be damaged.

2. What is the memory model of this machine? ddr3 1066？What brand? (Samsung gold bars?) ）

DDR3 memory, you can install 1066, the brand can't provide it, and the memory chips used in different periods are different, it's really hard to say. It is recommended to go to the market for on-site installation and testing, or contact the service station for installation.

3. Can the XP 32bit system upgrade 4G memory be recognized? If not, what can be done?

The 32-bit Windows operating system does not support the use of memory space greater than 3GB, and the actual effect is the same for both display and non-display. Only 64bit can be used normally.

4. What is the recognition of 4G memory in Win7 Professional Edition?

No matter what operating system, at present, Windows only has a distinction between 32bit and 64bit for large memory. Thank you.

Enjoy using it.

If you want to add memory to your computer.

Here are a few things to keep in mind.

1. Same brand, same frequency, same size.

If you plug in more than 1 memory on your computer, it is best to have the same brand and frequency, and your memory is DDR3

1600 refers to the frequency.

If this frequency is different, it may lead to incompatibility, which depends on whether the incompatibility is supported or not, and the following situations will occur.

For example, it crashes for no reason!

Blue Screen: There are several ways to upgrade your current one, but I suggest you just add another 4G memory, your memory is Jinbang's DDR3

1600's.

So you still have to buy Jinbang's 1600's.

In addition, computer memory mainly has the following sizes.

2G 4G8G (Older DDR.)

or DDR2 and smaller).

So the difference between 2G and 4G is only a few dozen dollars, and it's better to install a 4G once you upgrade.
