The graphics card and memory of the computer are going to be replaced, so I recommend it

There is a 2G in the memory

Graphics card upper block gt220 Mingxuan GT220 Transformers **400 more than good performance.

The new 40nm production process supports special effects and physical acceleration There is also a unique dual-pin temperature control technology Automatically adjust the wind speed according to the temperature of your graphics card The fan is also quite quiet Now it has also been upgraded with a new black box cooling Very good-looking.

512M 128bit DDR3 video memory specifications This card is quite cost-effective, and now Mingxuan graphics card makes a graphics card 2-year warranty is very good.

It's all about what you're going to do with your computer

Look at this configuration, and then buy a 1G memory of the same model and plug it in, forming a dual channel (or directly change to a 2G DDR2 800 memory).

It is best to buy a graphics card of about 500 yuan 9600GT or 9600GSO to take the chassis away, because the memory is not necessarily compatible, and the power of the power supply is not known if there is a problem

The memory does not need to be replaced, and a 1G DDR2 is added

Graphics card, you can consider the HD4670 of 400 yuan, which is cost-effective.

AMD's 4650 is just fine, and the memory depends on whether your motherboard supports DDR3

On the graphics card, Onda GT240 Shenge, the memory is increased to 2G, and it is the same as the previous model.

The memory can be increased, the hard disk can be replaced, but the graphics card generally cannot be replaced.

There are relatively few notebooks that can change graphics cards, because 99% of notebook graphics cards are directly soldered to the motherboard or integrated into the CPU. The interchangeable graphics card interface is generally a dedicated card slot. Take 10,000 steps back, even if you can change it, it is very difficult to find this kind of graphics card for you to replace.

Hard disks and memory can be replaced, but whether the graphics card can be replaced depends on the situation.

There are two types of graphics cards for notebooks: discrete graphics cards and integrated graphics cards.

Integrated graphics card, the motherboard with the graphics card chip integrated by the motherboard northbridge chip is called the integrated motherboard, and the graphics card chip integrated by the northbridge is the core of the integrated graphics card, and the core and video memory form the integrated graphics card. Integrated graphics cards are further divided into independent memory integrated graphics cards, memory division integrated graphics cards, and hybrid integrated graphics cards.

Independent video memory integrated graphics card is to have an independent video memory chip on the motherboard, which does not require system memory and operates independently. Memory division integrated graphics card, as the name suggests, a part of the memory divided from the host system memory as video memory for the integrated graphics card to call, which is why the machine with integrated graphics card often sees why the system memory displayed does not match the nominal, less, this is the reason. A hybrid integrated graphics card is one that uses both separate memory on the motherboard and memory divided from the memory, such as AMD's 780G chipset.

Obviously, the integrated graphics card is integrated in the north bridge, and it cannot be removed and replaced, as for whether the independent graphics card can be replaced, it depends on the model, the current model is basically welded up in order to be light and thin, the so-called independence refers to the independent graphics card chip and not necessarily the graphics card alone on a board, and the old high-end shifting ** workstation is mostly pluggable graphics card.

To sum up, hard disks and memory can be replaced, but whether the graphics card can be replaced depends on the situation. As with most current models, the graphics card cannot be replaced separately.

The CPU may be replaced, and the vast majority of graphics cards below 10,000 yuan cannot be replaced, and the memory hard disk can be changed at will.

The memory and hard disk can be replaced by themselves, and the graphics card is soldered to the motherboard and cannot be replaced by themselves.

It's a new machine!
