While top speed is nice, Stability & data integrity is top priority to many people & being able to utilize ECC Ram (Error Correction Code) is a huge plus of Ryzen, Since Ryzen memory Controller Does Support ECC... Confirmed by AMD, Despite not getting the server treatment of testing & validation... it %100 works!
very few Gigabytes Mobos does support ECC, MSI don't even bother, ASRock say All their AM4 Motherboards support ECC feature & confirmed by users!
& Asus... Here we want to compile a List of Asus Motherboards that Truely support ECC (unofficially) to clear any confusion!
Some motherboards state that they do & others seem to say ?X?&*#X?!X?...
for instance the ROG-Strix B450-F despite having an ECC ram in the QVL KSM26ED8/16ME(ECC)
says in it's specification page & it's manual... Un-buffered Non-ecc!
while the more affordable Prime B350-Plus clearly says in it's spec page Un-buffered memory
ECC Memory (ECC mode) support varies by CPU
Which means All Ryzen CPU's 1st Summit, 2nd Pinnacle & 3rd matisse will work with ECC
Except for Raven Ridge (Ryzen APU with Vega) only PRO versions would work with ECC
==========
Here is The list:
-ROG Crosshair VI & above [
Yes] confirmed to support ECC
*-ROG Strix x370-F [
uknown] specification page identical to Crosshair VI
-ROG Strix B450-F -E -I [
Yes] confirmed to support ECC by our friend
andersondiaz & Asus Support
**-Prime X470-Pro & higher [
Yes] confirmed to support ECC
*-Prime B350-Plus [
Likely]
-TUF B450-Plus [
Likely] Spec page say ECC Memory (ECC mode) support varies by CPU.
*by Supporting ECC we mean that ECC Mode is enabled & single bit errors will get corrected & we don't mean that the ecc ram will just run in Non-ECC mode!
**Asus Support replied to my email & Confirmed that ROG Strix B450-F will run in ECC mode if the CPU supports it!
Theoratically all Asus AM4 Motherboards should support ECC but here we need Confirmation from users! So if u know anything kindly share with us!
