ECC RAM compatibility

I bought ECC SO-Dimms for a 1L desktop.
@ibose @guest_999 @vivek.krishnan pointed that both motherboard + CPU compatibility are needed to utilize the ECC functionality.

At present the board has not rejected the RAM albeit it took 70-80 sec on first boot before the boot initiated. I wonder if there would be any implications down the line.
 
SO-DIMMS for a desktop?

this is normal. memory training.

No implications if things are running fine. Stress test using memtest to ensure stability.

All you need to check is if ECC is actually enabled and being used and the board has not put the memory in non-ECC mode. If you are running linux, then there are tools to check that. Not sure of windows.

1L / Minipc / Tiny ... Lenovo lists them as desktop

As I understand, it is the motherboard that supports ECC memory (quite an overlooked feature in earliest gen ryzen mobos before it was removed).

No, it's both. Motherboard manufacturers can decide whether to add ECC or not. But the CPU also needs to support ECC for it to work. All DDR5 Tiny's I've sold support ECC.

ECC won't be enabled as Q670 chipset does not support ECC . Will do memtest
 
If I'm getting this right your question is whether using ECC RAM as non-ECC will be okay. Then yes they will be fine. The difference between them both is that ECC RAMs aren't made to be as fast and that they are also more expensive but if you already have them then it won't matter. BTW this is DDR5 RAM sticks we talking about right? Then a little bit of delay during boot is normal because DDR5 sticks take some time memory training. DDR4 sticks are faster but the initial boot will still take half a minute or so.
