What is Motherboard ECC support?
Error correction code (ECC) memory is a type of RAM memory found in workstations and servers. It’s valued by professionals and businesses with critical data for its ability to automatically detect and correct memory errors, thus fighting data corruption.
Does AM4 support ECC RAM?
Correction: All the AM4 motherboards doesn’t specify ECC support.
Does Ryzen support ECC?
All Ryzen CPUs “support” ECC.
Will ECC memory work in a desktop?
The first, and most obvious, is that not every computer can use ECC memory. Most server and workstation motherboards require ECC RAM, but the majority of desktop systems either won’t work at all with ECC RAM or the ECC functionality will be disabled. ECC RAM is slightly slower than non-ECC RAM.
How important is ECC?
ECC memory further reduces the number crashes, which is very important in multi-user server applications. Generally, ECC memory is more expensive and there can be a slight slowdown when compared to non-ECC memory. The other components in the system, such as the CPU and motherboard, must also support ECC memory.
Which Ryzen supports ECC?
List of AMD Ryzen Processors with support for ECC memory

|---|---|---|
| AMD Ryzen™ 5000 Series Processors | V | Supported |
| AMD Ryzen™ 4000 G-Series Processors | V | Support only with PRO |
| AMD Ryzen™ 3000 Series Processors | V | Supported |
| AMD Ryzen™ 2000 Series Processors | Supported |
Where is the Register located in ECC RAM?
ECC RAM often uses registered, aka buffered, memory. Registered memory uses a ‘register,’ which is located between the system’s RAM and memory controller.
What kind of memory is needed for ECC?
As such, a similarly heavy-duty CPU is needed to support ECC memory. For Intel CPUs, only the Xeon line supports ECC, in an attempt to differentiate its enthusiast-level processors from enterprise-level ones. Meanwhile, AMD’s core -abundant Threadripper line supports ECC memory.
When is ECC memory is not registered or buffered?
In the event of a single bit being incorrect (a single-bit error), the ECC algorithm can reconstitute the data, but it can only notify the system of larger errors (two or more bits). ECC memory is not always registered / buffered. However, all registered memory is ECC memory.
