Check Memory Ram

Both server memory and normal PC memory are memory (RAM), and there is no obvious difference in appearance and structure, but the price is higher than normal memory. Server memory is also memory, it and we usually see in the computer city in the ordinary PC there is no obvious difference in appearance and structure, it is mainly in the memory of the introduction of some new technology, ordinary PC memory on the server is generally unavailable server can not recognize, This means that the server memory can not be arbitrarily for cheap with ordinary PC memory to replace the reason. Some people put some kind of technology inside ...

Designing 1 applications doesn't seem to be difficult, but it's not easy to achieve the optimal performance of the system. There are many choices in development tools, database design, application structure, query design, interface selection, and so on, depending on the specific application requirements and the skills of the development team. This article takes SQL Server as an example, discusses the application performance optimization techniques from the perspective of the background database, and gives some useful suggestions. 1 database design to achieve optimal performance in a good SQL Server scenario, the key is to have 1 ...

1. Installing too many operating systems on the same hard drive can cause the system to panic. 2.CPU, display cards and other accessories do not overclocking too high, to pay attention to temperature, otherwise, in the start-up or run will inexplicably restart or panic. 3. In the replacement of computer accessories, be sure to plug it, because the accessories contact bad will cause system panic. 4.BIOS settings to be appropriate, although it is recommended to set the BIOS to the optimal, but the so-called optimal is not the best, sometimes the best settings will cause startup or run panic. 5. It is best to be equipped with power supply to avoid voltage instability caused by panic. 6. If ...

This article is the software, hardware and virus three major aspects to analyze the system slows down the reason, and provides a system-specific acceleration techniques. ...

Today's demand for data centers is solid and effective, and this should be done first by "reasonable use". While idle resources are a waste of money for an environment. But if you fail to make a reasonable resource allocation to the frequently used data center, it will lead to a dangerous scene. A single hardware failure may cause other physical hosts to fail. The challenge for IT managers is to use and manage computing resources across the entire environment (usually including physical, virtual, and cloud resources). This article will discuss resource planning and problem mitigation as a means to achieve the goal of resource optimization. We will also ...
