There are PCIe riser cards that split a wide slot into 2 or more
narrower slots, for example 1 x8 slot becomes 2 x4 slots. These

Many of AMD's CPU/APU parts support ECC memory. Not just the top of the
line parts, but also many of the less expensive, less power hungry parts.
However, many (most?) of the boards for these chips do not support ECC,
or at least do not admit to it. They specify "non-ECC memory".
