thanks for the informative reply, > i3s and Pentiums officially support ECC my experience is that OEMs like Dell won't support ECC except for Xeon configurations. You can get the same machine with an i9 but not ECC memory or the Xeon and ECC.

Dell does actually sell Pentium machines with ECC support, like the smaller Poweredge servers such as T140. They've done this for a while, I personally run T20 with ECC and G3220 (sold like this by Dell). They do occasionally remove some features like IPMI from those cheaper processor options, but the ECC support stays.

> You can get the same machine with an i9 but not ECC memory or the Xeon and ECC. The desktop and workstation class Xeons are in direct competition with i9 processors in terms of raw performance, which is why Intel uses features like ECC to enforce product segmentation. This isn't the case for the low-end i3 and Pentium branded processors, because the Xeon lineup simply doesn't extend down that far. If you want to build eg. an industrial PC with ECC memory but you only need a low-end CPU, Intel's official solution is for you to get an i3 or Pentium processor because they don't have anything equivalent under the Xeon branding.

i9 and Xeon (officially) use a different PCH. So it's not really the same machine.

  Explaining in opposite: Pentium supports both PCH lines and supports ECC because they don't want to sell such cheap Xeon-branded CPU.

Well, that's a different segment, you won't find Dell selling you a 3900X and ECC in a server or workstation either. But OEMs like SuperMicro and Asrock Rack do officially support this, and sell barebones or pre-configured systems like this. https://www.supermicro.com/en/products/motherboard/X11SCH-LN4F https://www.supermicro.com/en/products/motherboard/X11SCH-LN... https://www.supermicro.com/en/products/system/1U/5019/SYS-5019S-WR.cfm https://www.supermicro.com/en/products/system/1U/5019/SYS-50... Workstation: https://www.asrockrack.com/general/productdetail.asp?Model=C236%20WSI https://www.asrockrack.com/general/productdetail.asp?Model=C... (and to be fair, Asrock Rack does have a few AM4 server boards and barebones, and these are among the few I would count on to actually validate ECC. It really just is something you have to explicitly go out of you way to find support for in the AMD ecosystem, whereas it's "free" on any C2xx server board in the Intel ecosystem, the default assumption is that it works because it's considered a supported configuration and that's not the case with AMD.) https://www.asrockrack.com/general/productdetail.asp?Model=X470D4U#Specifications https://www.asrockrack.com/general/productdetail.asp?Model=X... https://www.asrockrack.com/general/productdetail.asp?Model=1U4LW-X470#Specifications https://www.asrockrack.com/general/productdetail.asp?Model=1...
