A computer whiz takes a look at what memory modules I should buy for my computer

Your motherboard should be a 915 compatible with DDR and DDR2 memory, but you already have DDR 400, so buy DDR memory, the high latency of low-frequency DDR2 makes high bandwidth meaningless.

Of course, DDR2 memory is cheaper now, and buying a DDR400 512 is also in the early 100s, so you can also buy a 1GB DDR2 memory to sell the current memory and save costs.

Didn't you write it all, your chipset supports up to DDR2-533, then you buy two DDR2-533 memory 1GB each, the performance will be better than a single 2GB, Kingston (Kingston) is recommended, compatibility and stability are good.

Access speed PC3200 description.

You are now using DDR400, so buy DDR400 memory sticks, use Samsung particles, good compatibility, now 512 DDR400 strips are about 100 yuan.

Don't think that adding memory will definitely be faster, then it depends on whether the memory is not enough, if you are 512, it is basically enough, it can only mean that you can't keep up with other configurations. If it's lower than 512, then you can add one, plus 1g.

Your CPU is 133 external frequency, with DDR-266 SDRAM, DDR-333 SDRAM, DDR- 400 SDRAM, DDR2-400 SDRAM, you are not afraid of bad CPU overclocking to 200 can also use DDR2- 533 SDRAM (memory asynchronous external frequency is 266).

The capacity does not exceed 2g

1. In layman's terms, the role of memory modules in computers is equivalent to a bridge, which is responsible for the data exchange and processing between hardware such as hard disks, motherboards, graphics cards, etc. All computer data transfer to the processor is processed through memory modules and processors.

2. The read speed and storage speed of the memory are the fastest, and the direct exchange speed with the data bus on the motherboard is very slow, and you can also regard the memory as a data buffer, which has a cache area, which is also more conducive to the speed of the computer processing data.

Memory is indispensable to every computer and plays a very important role in the computer system, so what is it for? Today, let's take a look at the specific role of the regulars in this computer.

Answer: Memory modules can be read and written more quickly, and data can be saved faster.

The larger the memory, the larger the amount of data that can be carried by the burner, and the corresponding speed is faster.

The better the memory card, the faster it can read, write, and load, especially when playing games and preparing for dry work.

1. Memory module is a more advanced storage technology than solid-state drive, its read and write speed is more than ten times faster than that of hard disk, taking the current mainstream DDR4 generation memory module as an example, its read and write speed can reach more than 7000MB s, and the traditional mechanical hard disk is no more than 300MB s, even if it is the most powerful at present.

NVMe SSD, the speed is also 3000MB s.

2. So what is his role? Because the CPU processes data super fast, and the read and write speed of the hard disk is very slow, they have a speed contradiction when they exchange data, just like I (CPU) urgently need a commodity (data), after Ma Yun's house orders (send demand instructions), I need to wait 3-5 days to receive it (the transmission is too slow), during which I have nothing to do, I can only wait.

At this time, the read and write speed is auspicious, and the ultra-fast memory module can help a lot.

When we boot or open the software, the hard drive will transfer the data needed by the software to the memory module and save it.

This is the boot speed and the speed at which the software is opened or the game is opened, and the traditional HDD is very slow to transfer this data to the memory module, so the speed of booting and opening the software is very slow).

First of all, you have to ensure that you will disassemble, the laptop is not easy to disassemble, especially HP's, the cover is very man, and every time I disassemble it, I will inevitably have a few more screws and nowhere to install it, and secondly, it depends on how many generations your computer is configured, if the configuration of the 2nd generation is installed with the 3rd generation of memory sticks, it is definitely not possible, you have to check it out before buying.

Ordinary laptop memory modules, as long as they are of the same model and have the same slot, are compatible (except for a few exceptions).

1. The general principle is to give priority to the use of memory modules of the same brand and model as the assembly. If you want to expand the capacity, you should also give preference to the brand's memory modules.

2. The low-voltage version can replace the high-voltage version, and the high-voltage version may not be suitable for the low-voltage version (but most of them are still compatible with each other at present.)

3. It is advisable to replace the low working frequency with a high working frequency, and it is not advisable to replace the memory module with a low working frequency, otherwise it will reduce the running speed, or even crash or not work.

4. The slots must be consistent, this is the most important.

5. You don't have to choose a memory module with a check digit.

1.Find out what your motherboard is, check out the maximum amount of memory it supports, and how many memory module slots it has. Some have only one slot, while others contain two.

2.Desktops and laptops have different slots for memory modules, and the arrangement of the gold fingers of the memory modules is also different. Desktop memory modules are longer, while laptop memory modules are wider and shorter.

3.Nowadays, the average memory is three generations. i.e. DDR3.

DDR3 is different from DDR3L. DDR3L means low pressure, ie. And DDR3 is.

Therefore, you should pay attention to this detail when purchasing. Otherwise, incompatibility may occur.

4.The operating frequency is also the most important parameter. The general memory operating frequency is 1600MHz and 1333MHz.

5.If you know that your computer can increase memory, the safest way to buy is to use a hardware detection tool to check the memory information of the computer. Buy the same memory module as the original.

It is not recommended to upgrade the memory.

Such a configuration is too old, upgrading the memory is a waste of money and the effect is not obvious.

It's a bit of a waste, don't spend money to upgrade the memory, if you really want to upgrade, you can also add a suitable independent graphics card should have a good effect, just buy a second-hand graphics card, don't buy a new one,
