Which is better ECC or non-ECC memory?
At the cost of a little money and performance, ECC RAM is many times more reliable than non-ECC RAM. And when high-value data is involved, that increase in reliability is almost always going to be worth the small monetary and performance costs. In fact, anytime it is possible to do so, we would recommend using ECC RAM.
Is ECC RAM really necessary?
You need high-end, battery-backed fully hardware RAID with onboard RAM to ensure that you don’t lose data due to a power outage, disk failure, or whatever. So no, you don’t really need ECC RAM in your workstation. The benefit simply will not justify the price.
Can I mix non-ECC and ECC RAM?
No, these will not work together. Many motherboards simply won’t work with ECC memory either.
Can I replace ECC memory with non-ECC memory?
Many motherboards support both ECC and non-ECC memory. Some sources say you can even mix the two types of RAM and the ECC RAM will work as non-ECC memory. However, most memory companies do not support mixing the two types, so try it at your own risk.
Which AMD motherboards support ECC?

Does DDR4 have ECC?
Most desktops would use the cheaper DDR4 memory, most servers the ECC memory, and yes, a good part of the price difference is because it’s ECC.
Do laptops use ECC RAM?
In general, laptops do not use ECC memory. There may be military-spec models available, but you will not find ECC memory on any retail laptop model. For ECC to be implemented, the motherboard memory controller must support ECC.
Why is server RAM so cheap?
Supply and Demand: The demand for such large RAM capacities on a single stick is mainly for servers at this time, and the amount manufactured (supply) will be higher. So, both Supply and Demand are higher for 8 GiB ECC RAM sticks than they are for non-ECC, making them substantially lower in price.
Does Ryzen support ECC?
Ryzen has no official ECC support, but will utilize ECC RAM, if available. Motherboard manufacturers must support ECC operation mode. The chipset is irrelevant.
Do AM4 motherboards support ECC?
So, I believe we can now say that All ASUS AM4 Motherboards DOES support ECC if the CPU supports it unless/until someone proves otherwise…
Does Ryzen 3 support ECC?
[Motherboard] List of AMD Ryzen™ Processors with support for ECC memory. Please note that when it comes to APUs (Ryzen 3000/4000 G-series), only PRO processors (e.g. Ryzen 3 PRO 3200G) will support ECC memory.
