[OpenIndiana-discuss] Which mobo allows 24 GB ram and ECC

[Robin Axelsson]

So it seems that on the Intel side, only systems with Xeon CPUs support 
ECC RAM, so none of Intel's current line of i3/i5/i7 CPUs support ECC. 
When it comes to VT-d extensions (or IOMMU on the AMD side) for 
virtualization, the following page might be a good help:
