What is server memory?

Random access memory, or RAM for short, is used to store the data of what's running on your server. Data is transferred to server memory as it's fast, faster than your server's storage. This ensures that critical data can be accessed and processed by the CPU as quickly as possible, keeping the performance of the server up.

However, server memory is what's known as volatile. Meaning that when the server loses power, the memory also loses the data that's stored in it at the time. So, you can think of RAM as your server's short-term storage, while its HDDs and SSDs are its long-term, non-volatile storage.

Upgrading server memory

The more memory a server has, the more of this data it will be able to store. This, in turn, enables a server to run more complex, memory-hungry programs and workloads. With more server memory you could run more virtual machines simultaneously, for instance, increasing the productivity and efficiency of your server.

What is ECC, and why do I need ECC server memory?

Whether it's a consumer laptop or enterprise server, every computer is subject to electrical and magnetic interference from background radiation. At a tiny, tiny scale, this interference can cause the 1s and 0s that make up a bit (as in bits and bytes) of data in RAM to flip to their inverse values.

For the most part, it's inconsequential. It won't be the end of the world if the RAM of a gaming PC has one of these single-bit errors while playing Counter Strike, for example.

In a mission-critical server environment, however, stability and reliability are essential. This data corruption - even if it's just a lone instance of a 0 turning into a 1 - can have a knock-on effect, producing invalid data and potentially wasting hours' worth of server processing time.

That's where error-correction code, or ECC for short, comes in. As the name implies, ECC server memory detects and corrects for these errors before they're written to memory, ensuring data integrity.

Hardware-wise, there isn't much difference between ECC server memory and any other ordinary stick of RAM that you'd find in a desktop or laptop. ECC server memory just has one extra chip on it that handles the error-correction code. Rather, it's the processor-motherboard combo that determines support for ECC memory or not.

This error-correction process makes ECC server memory ever so slightly slower than non-ECC RAM, hence why it's not used in consumer devices which value raw performance over data integrity. That, and it's a cost-saving measure for manufacturers.
