Which is the best effect and faster speed increase for a notebook with an SSD installation system an

Intensive operations such as encryption and decryption, compression, decoding, transcoding, and adding memory will be faster.

Lightweight computing tasks such as opening web pages and loading documents, and installing SSDs is fast.

Explanation: Anything must be loaded into memory before it can be executed, virtual memory just saves nothing that needs to be executed, and system logs to disk first, and must also be loaded into memory when needed. Because all ** depends on the CPU to execute, the CPU only addresses memory, and the addressing disk is the interrupt service provided by the disk ROM, which is related to the disk master and has nothing to do with the CPU.

Adding an SSD does improve memory performance, because by putting nothing that needs to be done in the virtual memory (disk), there is more free memory and no need to refresh for things that don't need to be done. The reload is also much faster when the paging of the virtual memory is requested from the system.

Before buying an SSD, it is recommended to find out if your motherboard has, or ESATA interface, mstata, if the speed is 6GB s, 6GB is actually 6GBIT, which is equal to (6 8=theoretical maximum speed; The theoretical maximum speed of 3GB s is (768 2=384Mbyte S), so you will not be able to enjoy the ultra-high read speed of 500Mbyte S claimed by the SSD. Also pay attention to whether the SSD supports TRIM, otherwise the more you use it, the slower the write speed. The SATA mode of the motherboard should also be replaced with ACHI, and then the Intel fast storage driver should be installed to fully exert the performance of the SSD.

If the memory is DDR2, if you want to form a dual-channel, you must have two memories of the same brand and the same model, DDR3 is a lot smarter, as long as it will be in accordance with the minimum configuration of the memory as the standard to form a dual-channel, for example, 800MHz 1GB memory and 1333MHz 2GB memory to form a dual-channel becomes: 800MHz 1GB dual-channel, and 1GB is used as switching memory.

If you exceed 4GB of memory, you can only use a 64-bit system, and the number of memory supported by a 32-bit system is (2 32=4294967296 bytes=4GB), but in fact, it is only more than 3GB because of the system. Now stand-alone games basically support 64-bit systems, and there are still many online games that are not supported, so it is recommended to change to 2GB dual channels.

Solid state, and then install the system, the biggest embodiment of this is the boot speed. Running multi-threaded games and the like,The biggest thing is to look at the memory.,You're 4G.,It should be enough.,The whole dual channel plus a 4G.,The memory is 8G.,That's even more powerful.。 However, a 64-bit operating system is required.

Of course, the SSD has improved significantly, and the SSD tries to increase the capacity of the same series of hard disks, 128, which is much faster than 64G.

It should be that the SSD installation system has been improved a lot, so that it takes more than ten seconds to boot up all day, how cool.

However, LZ even bought an SSD, so it's not a problem to spend two or three hundred to buy a memory module.

How much can the performance of a computer memory upgrade be improved by dual-channel? Theoretically, memory dual channel is twice as fast in data exchange as memory single channel.

1.However, the memory speed is very fast nowadays, and if your computer's CPU speed is not very fast, then you will not improve the performance of the computer much even if you use the memory dual channel. The money you spend on memory is better for other accessories.

Of course, if you have a small memory, then you can build a dual-channel memory that will improve the performance of your computer. However, the credit is not due to dual channels, but to the increased memory capacity.

2.As the CPU speed of the computer continues to increase, the memory speed also increases. But overall, the rate of improvement in memory speed has always lagged behind that of the CPU.

In order to give full play to the best performance of the CPU, major manufacturers have successively developed memory dual channels. The so-called memory dual-channel means that two memory modules can run in parallel at the same time. This greatly improves the speed of data exchange between the CPU and memory, thereby improving the performance of the whole computer.

3.In addition, due to the different architectures of Intel and AMD processors, the impact of forming memory dual-channel on these two different CPUs is also different. According to reports, memory dual-channel improves Intel CPU performance greatly, while memory dual-channel has less impact on AMD architecture CPU.

This is mainly due to the fact that AMD processors already have the function of memory dual channels internally, so the formation of memory dual channels is equivalent to increasing the memory capacity. Of course, these are just theoretical statements, who is right and who is wrong, there is no basis for words, and data is proof!

4.The impact of dual-channel memory on the GPU platform is not obvious, and its biggest role is to improve the performance of Intel core graphics cards and AMD GPU cores.

The AMD platform outperformed single-channel memory with dual-channel memory when running 7-zip software, with an improvement of about 8%. In terms of Intel platform, although there is an improvement, it is not obvious, and the performance improvement of the dual-channel platform is about 4%. Obviously, the power of the processor alone cannot be demonstrated by the power of the dual channel.

5.The improvement in graphics performance on the dual-channel platform is very significant, with the AMD platform increasing by 33% and the Intel platform also improving by 19%. For gamers who use Intel's core graphics platform or APU platform for game entertainment, building a dual-channel memory platform can effectively improve the game performance of the console.

6.Under the premise of the same picture settings, the frame rate can be increased by more than 50% compared to a single channel using dual-channel memory. Therefore, in order to get better game performance under the core graphics platform, it is necessary to build a dual-channel memory platform.

7.For players who use a discrete graphics card, they can choose a more expensive single memory, and there is no need to worry about the problem of dual channels. For those who use Intel's core display platform and APU platform, if you want to get better graphics processing capabilities, you should focus on the dual-channel platform.

Is there a discrete graphics card? If there is a dual-pass single-pass that has little effect on the speed, if it is a nuclear display, the dual-pass will improve the speed of the graphics card to a certain extent.

Dual-channel performance is 10% to 20% better than single-memory performance. You look at web pages, movies, there is no pressure on this configuration, single core can do it, if you play games, 4G can only be said to be enough, the graphics card is the first accessory, if you don't have a graphics card that can keep up, there is no need for memory upgrades.

If you can't feel it in daily use, if it's an APU, the impact is more obvious.

Dual-channel doesn't have a big impact on Intel ICS, but it does have a big impact on AMD.

Dual-channel memory modules must be the same, because when a computer is working, memory is usually divided into several parts, with each channel using one piece of memory. If two adjacent memory channels use different capacities of memory, the computer will have problems accessing the memory and will slow down the performance of the compute machine.

However, it is important to note that the capacity of the memory can be different, but the clock speed should be the same. If the clock speed is different, the faster memory will be forced to slow down, reducing system performance.

In addition, there are laptops that can use a mix of DDR3 and DDR4 memory, but in this case, the Hengda Brigade system only works with the speed of the slower DDR3 memory. Therefore, it is best to avoid mixing different types of memory.

In conclusion, to ensure the stability and performance of your computer, it is recommended to use a memory module of the same size and speed. If you have to use different capacities, make sure they are the same speed. <>

1. Some of the memory in the notebook is shared with the integrated graphics card, if a dual-channel memory is formed, a memory module will inevitably decrease during the period, resulting in system lag.

2. Dual-channel memory will increase energy consumption and reduce battery life.

3. Dual-channel memory will increase the space of the notebook, due to the high integration of the notebook, the assembly will break the integration, resulting in inconvenient carrying.

Definition of dual channel: 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.

The role of dual channels: the CPU can address and read data separately in these two memories, thus doubling the bandwidth of the memory and doubling the data access speed (theoretically). The popular dual-channel memory architecture is built with two 64-bit DDR memory controllers with a bandwidth of up to 128 bits.

Because the two memory controllers in the dual-channel system are independent and complementary intelligent memory controllers, they can operate simultaneously with zero waiting time between them. This complementary "nature" of the two memory controllers allows for a 50% reduction in effective wait time, doubling the bandwidth of memory.

Of course, it is necessary to form a dual channel, and the dual channel is not comparable to a single pass. The brand is a popular brand, and you don't need to buy too luxurious.

Dual-channel can run faster, Kingston's is very good, but there are a lot of fakes, in fact, 4GB is enough.

In view of the fact that DDR2 is about to be discontinued. If you want to upgrade, hurry up.

I think if you support dual-channel, try it out.

Because after this machine is upgraded to 2G, it will not consider upgrading the memory in the future, so it is useless to keep a slot. It's better to run out now. And his performance improvement should be noticeable!

Dual-channel mode can only be enabled when the number of memory modules is double and the capacity is the same.

Only two memory modules with the same size (e.g. 2g*2) can be dual-channel.

Dual-channel first of all, the computer should support,And it must be two with the same capacity,The same specification,The same frequency and the same batch of memory,Different models of capacity are not able to form a dual channel,It's best to use the same brand。

Dual-channelIt is to design 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. In these two memory, the CPU can address and read data separately, doubling the bandwidth of the memory and doubling the speed of data access (theoretically).

SSD Pros:

Fast read and write speeds: Flash memory is used as the storage medium, and the read speed is faster than that of mechanical hard disks. SSDs do not use a magnetic head, and the seek time is almost zero.

The sequential write speed is very impressive, and most SSD manufacturers will claim that their SSDs have sustained read and write speeds of more than 500MB s! The speed of the SSD is not only reflected in the continuous read and write, but also the fast random read and write speed is the ultimate meaning of the SSD, which is most directly reflected in most of the daily operations. Related to this is the extremely low access time, the most common 7200rpm HDD has a seek time of 12-14 milliseconds, while SSDs can easily reach milliseconds or less.

Shock and drop resistance: Traditional hard disks are disk type, and data is stored in the disk sector. The SSD is made of flash memory particles (i.e., storage media such as ***, USB flash drive), so there are no mechanical parts inside the SSD SSD, so that even if it is moved at high speed or even accompanied by flipping and tilting, it will not affect normal use, and the possibility of data loss can be minimized in the event of collision and **.

Compared to traditional hard drives, SSDs have an absolute advantage.

Low power consumption: SSDs consume less power than HDDs.

No noise: SSDs do not have mechanical motors and fans, and the noise level is 0 dB when working. Flash-based SSDs consume less energy and generate less heat in operation (but high-end or high-capacity products consume more energy).

There are no mechanical moving parts inside, no mechanical failure will occur, and there is no fear of collision, shock, vibration. Because SSDs use flash memory chips with no mechanical parts, they have the characteristics of low heat generation and fast heat dissipation.

Wide operating temperature range: A typical hard drive can only work in the range of 5 to 55 degrees Celsius. While most SSDs can work at -10 to 70 degrees Celsius.

SSDs are smaller and lighter than HDDs of the same capacity. The interface specifications and definitions, functions and usage methods of SSDs are the same as those of HDDs, and the product shape and size are also the same as those of HDDs. Its chips have a wide operating temperature range (-40 to 85 degrees Celsius).

Lightweight: SSDs are lighter in terms of weight, 20-30 grams lighter compared to regular inch drives.

The first problem, a single channel is 64bit, dual channel is 128bit, the improvement is the memory read and write performance, the increase is nearly doubled, you can compare the number of lanes on the highway 4 lanes and 2 lanes difference, this will be improved for some memory performance-sensitive programs;

The second problem, solid-state drives, compared with mechanical hard disks, improve the read and write performance of the hard disk, especially the random read and write performance, which is reflected in the use, the system startup is accelerated, and the application loading is accelerated, because the system starts, and the application loading has a data loading process from the disk to the memory;
