If a desktop computer wants to be equipped with a second memory, can the desktop computer host inser

You have to look at the model number of the memory module...

ddr1ddr2

33 types of DDRs. Generally speaking, the big ones are the old ones. It could be DDR1 or DDR2(However, you still need to check the memory, the text on it will tell you clearly).

Now the technology is getting better and better. The newer and smaller things you make.

The best way to expand the memory module is to buy the same brand and the same capacity (average capacity) to prevent the blue screen caused by incompatibility.

Here's my previous question about memory expansion. You can take a look.

It doesn't matter how tall or short the memory is, but it must be the same model. DDR2 and DDR3 cannot be mixed, so you'd better unplug your old memory and take it with you to buy a new one.

When you buy it, ask the merchant or compare the appearance yourself, and you will know that the models are inconsistent, and the notch position of the gold finger socket of the memory is not the same. Otherwise, if you buy it back, the new memory will not be plugged in.

As for compatibility, mainstream brands are generally fine, such as Kingston, Apacer, etc.

As long as it is three generations, the problem is not big, the shape does not matter, not to mention the same brand, different brands can be used.

What kind of memory are you using now? If it's DDR2, it's DDR2, DDR3 is not compatible with DDR2.

Basically, no, don't worry.

As long as there are two memory slots on the motherboard of the computer, two memory modules of the same size and model specifications form a dual-channel memory, and the performance of the computer will be improved.

Steps to install a memory module on a desktop:

Open both bayonets on the motherboard's memory slots. Prepare the memory for installation.

Then pick up the memory and align it with the motherboard's memory slot bayonet. The notch on the memory is a short note alignment on one side.

Note: If it does not match, the motherboard and memory cannot match.

After aligning the slot, press both sides of the memory with both hands and press it down, and you will hear a "pop" sound. It means that the memory is completely in the slot.

Check that the memory is fully installed in the slot.

XP 32-bit? If you want to change the system, besides, the graphics card is basically DDR 1333 now, and you add memory to waste money, so change the host.

32-bit systems support up to 4GB of memory. 64-bit systems can support it.

Yes, 32-bit recognition is less than 4G, 64-bit recognition.

If the incompatibility issue does not occur, your system is a 64-bit system and 6G of RAM will be detected.

First of all, I would like to remind you to see if that 4G strip is 2nd generation.

Second, see if your system is 64-bit or 32-bit. 32-bit is not recognizable 6G, 64-bit can. (This refers to the system above win7, and the XP64 bit can only be recognized as 4G).

Finally, plug the 4G RAM into the board to see if the 2G strip is also compatible.

Yes, but 6G will not be displayed, up to 5 o'clock.

1.As long as the hard disk interface is the same, you can add it.

2.As long as your motherboard supports 2G memory, but the premise is that your motherboard memory slot is not full 3There is no direct relationship between hard disk and memory.

There are many models of 4-core CPUs**, and it's not the same AMD's cheapest 4-core CPU is Athlon 2, about 700, and Wing Loong 2's 4-core, so far I know about 900.

There are more varieties of inter's 4-core CPU, and sometimes you don't need to be superstitious about 4-core, and more heads are not necessarily faster, and some 4-cores are cheaper than dual-core, and AMD's Athlon-4-core CPU I don't think it's as good as Pterodactyl's 3-core.

Add hard disk to see if your power supply is enough, if not enough will crash and then there is the corresponding interface is enough, now some motherboards have 2 serial ports, and the new hard disks are usually serial ports, if you use the optical drive of the serial port, then there is no available interface, plus the expansion card, it is quite troublesome, it is not easy to get it if you don't understand

If it was equipped with dual cores at that time, the motherboard was not expected to be too high-end, and you need to think about whether the CPU with 4 cores can play a role

Memory, as long as the model is matched, it is generally OK

Can be installed.

It is mainly determined by the hard disk interface, memory slot and motherboard parameters of the motherboard.

1. Motherboard hard disk interface diagram.

Note: This GIGABYTE motherboard can be connected to up to 5 hard drives.

2. Memory slot**.

Note: This model can be inserted into up to 4 internal memory.

The maximum amount of memory supported by a single root is determined by the motherboard parameters.

You can add it directly! No problem, the hard disk is external memory, the memory is internal memory, and if you look at the price, you have to look at the specific model.

Generally, the actual purchase is 30-50 cheaper than **!

Add a 2G to the memory, can you add it directly? Yes. What is the relationship between hard disk and memory?

Now I use the dual-core one, it doesn't matter. My desktop hard drive is now 160g, and I want to add another 320, which is okay. Unit price: Check your model online, it's OK.

Installing 2 computer host memory modules can form a dual channel, which will make the computer run faster.

Dual-channel is the design of two memory controllers at the Northbridge (also known as MCH) chip level, which can work independently of each other, and each controller controls a memory channel.

Technical principle. Dual-channel memory technology is actually dual-channel memory control technology, which can effectively increase the total bandwidth of memory, so as to adapt to the needs of data transmission and processing of new microprocessors. The dual-channel DDR has two 64-bit memory controllers, and the dual 64-bit memory stack provides the same bandwidth as a 128-bit memory stack.

The dual-channel system consists of two independent, complementary smart memory controllers that can be operated in parallel. For example, when controller B is ready to enter.

The next time the memory is accessed, controller A is reading and writing to the main memory and vice versa. This complementary "nature" of the two memory controllers allows for a 50% reduction in effective wait time, so dual-channel technology enables memory.

Bandwidth doubled. The core of its technology lies in the fact that the chipset (northbridge) can address and read data on two different data channels, and the RAM can reach 128bit of bandwidth.

With more memory, the computer will run faster, and if you can form a dual channel, the performance will be better.

Benefits: When you open more software, the computer responds faster, and other situations do not feel obvious.

You don't need any merging software, as long as your motherboard can recognize the memory you've installed.

There is no advantage or disadvantage to one and two, but if you have one more memory, the computer will be faster.

If you install 2 RAM, you can make your computer much faster.

You only need to look at the frequency to add a memory module, and it is best to add a strip with the same frequency, without other software or drivers.

Whether the desktop memory can be inserted into 2 different strips depends on the situation:

1. Different process specifications cannot be inserted and used at the same time: Generally, the motherboard will only support one specification of memory, and if the two memory specifications are different, it cannot be inserted and used at the same time.

Now the mainstream memory is DDR memory, which is divided into four generations (the frequency is different and the cavity rate is different, and the pins and notches are also different).

DDR memory: working frequency 266MHz, up to 400MHz

DDR2 memory: working frequency 400MHz, up to 800MHz

DDR3 memory: working frequency 1333MHz, up to 1866MHz

DDR4 memory: working frequency 2133MHz, up to 4266MHz

2. The same type and different frequencies can generally be used at the same time: if they all belong to the same type of memory, such as DDR2 memory, but the working frequency is different, it is generally used from high frequency downgrade to low frequency.

3. The same type and different capacity can be used at the same time: the type is the same, but the capacity is different, such as a 1g, a 2g, as long as the specifications are the same, it can generally be used at the same time.

Yes, but memory is mixed, so be aware of the following points:

1. The frequency should be consistent. For example, if it turns out to be 1333, it's best to find 1333 memory.

2. If the frequency cannot be found consistently, DDR3 generation memory, you can find a similar frequency. For example, if you use 1066, you can generally use 1333, but don't use 1600, it is likely to be incompatible.

3. To increase the memory of the old motherboard, it is best to use a double-sided 16-particle one, which is much better than the compatibility of single-sided 8-particle or single-sided 4-particle technology.

4. Notebooks, there are often some models that only support low-voltage memory, pay attention when increasing, if you buy a standard voltage, it may be unstable due to insufficient power supply.

5. Sometimes, the order of memory will also affect compatibility. For example, if you have two memory slots, the order of the two memory slots is reversed, and sometimes the compatibility will be changed.

It can be installed, as long as it is the same specification of memory, it can be used, DDR3 specifications, 248G can be compatible, and the frequency is 1333

1866 can be used,The same computer is composed of 4G+8G is 12G memory,
