How much is a 1g DDR memory module, and how much is a 4G DDR

As said on the first floor, DDR400 is the first generation, and DDR667 is the second generation, but now the DDR800 has appeared, so it is better to buy the 800 if you want to buy it. It depends on how much memory it is, if you don't want to be professional, right-click on my computer, select Properties, and below the CPU information is the size of your memory. If you want to be more detailed, you need to find a tool, like Optimizer, which is very easy to use.

As for the price, the second generation is about 120 or 130 now, and the 800 may be more expensive.

Electronics are now getting cheaper and cheaper, and you can choose to buy better ones while waiting.

If you are DDR400 and buy DDR667, you cannot use it on your computer because the slots are different.

If you click on the memory in CPU-Z, if DDR2 appears, it is DDR2, and if DDR appears, it is DDR1

DDR1 Yes ; DDR2 has . It's best to choose according to the maximum memory frequency supported by your motherboard configuration, if you can't support a large frequency, it's useless to buy a large one, it will automatically drop to the maximum frequency supported.

The current generation 1g is about 190

The second generation 1g is about 120

DHR400 is a first-generation memory module DDR667 is a second-generation memory module The second generation cannot be used on the first generation.

Use the optimization master to see how much the memory module is.

The generation 1g is about 200.

The second-generation 1g is about 150.

DDR400 DDR667 400 and 667 are frequency sizes DDR is a series If your computer can press DDR400, you can press DDR667 That's a motherboard support issue.

DDR2 is the second generation, DDR2 cannot be installed on your computer, don't confuse it if someone is in front of you.

About 120, you must buy memory in a buy store, many of them are grinding strips on the market, and the general memory is guaranteed for one year, remember that the question mark is clear about the boss, how long is the warranty.

The DDR for 4G is 4096MMB: full name megabyte (mbyte); GB: Gigabyte (GB).

GB: Gigabyte (GB). Computer storage capacity units are generally expressed in bytes (bytes), kilobytes (KB), megabytes (MB), gigabytes (GB), terabytes (TB), petabytes (PB), exabytes (EB), zeta bytes (ZB, also known as all bytes), and Yaota bytes (YB).

1kb=1024b

1mb=1024kb

1gb=1024mb

Not necessarily, DDR is more expensive, DDR2 is cheaper. DDR3 should not have a single 1G bar.

DDR3 Introduction:

The first-generation memory technology for Intel's new chip (but currently mainly used for graphics card memory), the frequency is above 800M, and the advantages compared with DDR2 are as follows:

1) Less power consumption and heat generation: The lessons of DDR2 have been learned, and the energy consumption and heat generation have been reduced on the basis of cost control, making DDR3 easier to be accepted by users and manufacturers.

2) Higher working frequency: Due to the reduced energy consumption, DDR3 can achieve a higher working frequency, which makes up for the shortcomings of longer latency to a certain extent, and can also be used as one of the selling points of the graphics card, which has been shown on the graphics card with DDR3 video memory.

3) Reduce the overall cost of the graphics card: DDR2 video memory particles are mostly 4M x 32bit, and 8 128MB video memory commonly used with mid-to-high-end graphics cards is required. The DDR3 video memory specification is mostly 8M x 32bit, and the capacity of a single particle is large, and 4 particles can form 128MB video memory.

In this way, the PCB area of the graphics card can be reduced, the cost can be effectively controlled, and the memory power consumption can be further reduced when the number of particles is reduced.

4) Good versatility: Compared with DDR to DDR2, DDR3 has better compatibility with DDR2. Since key features such as pins and packaging remain unchanged, DDR3 video memory can be used with a slight modification of the graphics card with DDR2 graphics core and public design, which is beneficial to manufacturers to reduce costs.

At present, DDR3 graphics are widely used in most of the new mid-to-high-end graphics cards.
