While the RAM you have in your PC is probably non-ECC, some consumer hardware actually supports ECC memory. Why is this the case? Can I Use ECC RAM on My PC? It’s normally used in systems where stability is an absolute priority, and data corruption cannot be tolerated, such as certain kinds of servers and workstations.ĮCC memory can prevent most memory-related crashes in PCs that support it, but for some reason, the RAM most of us use in our personal PCs is non-ECC, meaning that single-bit errors can mess up-and crash-our PCs. Most ECC memory use code that can correct single-bit errors and detect, but not correct, double-bit errors (SEC-DED). CrucialĮCC stands for “error correction code,” and in the context of RAM, ECC RAM is a type of computer memory with an extra chip that can actually detect whenever there’s an error in memory, like a flipped bit, and correct it in real-time before it can actually wreak any havoc. DIMM and SODIMM ECC RAM modules, with nine chips each. A memory error can be caused by anything, including cosmic rays ( we’re not joking). Errors will occasionally slip through, and when they do, they might just cause your PC to crash. But of course, it doesn’t always go perfectly. Our computers transfer data in and out of RAM constantly, and most of the time, this is a painless process.

First off, we need to clarify what ECC RAM is.
