1. First of all, in terms of selection, for
ordinary memory such as PC memory, etc., everyone usually weighs the performance differences between different brands and different products, and pursues a price-performance ratio.
Server memory is different. The most important thing for server memory is stability and error correction. It will not pursue higher frequency or speed, but it will pay more attention to technology. It can be said that some advanced technologies are used in server memory. , and most of the advanced processes are used in ordinary memory.
2. Then from the technical level,
the memory stick of the server supports ECC error checking technology. After error checking and correction, the stability and reliability of the server system is virtually guaranteed. The main function of ECC technology is for data error correction. After all, server memory is usually a long-term workload, and it is normal to work continuously for a month. In order to ensure stable operation, the data in the memory must be corrected. , to ensure the correct communication and execution of computer instructions.
In addition, the hot-swap technology is also an important technology to ensure the continuous and stable operation of the server, so that maintenance personnel can directly perform plug-in and pull-out operations on the memory when the server is running normally with power on. When an ordinary memory module detects an error, it cannot determine which bit the error is in, nor can it correct the error. Ordinary memory usually only needs to work continuously for a few hours or more than ten hours. Ordinary memory sticks do not have hot-swapping technology, and you need to shut down and power off the PC if you want to replace the memory of the PC.
3. Afterwards, from the configuration level,
the memory stick capacity of the server usually starts at 32GB, and the server will also choose to install a large-capacity memory stick according to the actual situation.
4. From the aspect of use
Usually, the memory stick of the server can only be used for the server, and the ordinary memory stick can only be used for the desktop, and they cannot be interchanged, otherwise they will not be able to boot normally. However, the memory sticks of AMD platform servers can be used on ordinary computers, but sometimes they are unstable; the memory sticks of INTEL platform servers cannot be used by ordinary home computers, but can only be used on server platforms.
5. Also from the price level
For memory sticks of the same brand, specification, and capacity, the price of server memory is usually much higher than that of ordinary memory.
