It is registered ram. The second link is the datasheet
http://www.micron.com/products/modules/ddrsdram/part.aspx?part=MT18VDDT3272DG-265

I believe that will beep like crazy on an A7N8X, and will refuse to post.
As for your Epox 8KHA, it is KT266, and is roughly the same design
as the KT333, according to Via. Since the A7V266 can take registered,
it isn't a complete surprise that the Epox 8KHA can too. It is just
bothering me that the A7V333 manual makes no mention of accepting
both types. In this case, it probably doesn't help that much,
because while it accepts registered RAM, I believe it might have
a restriction on chip width, so a 1GB registered module with x4
chips might not work on the A7V333, as otherwise you could use the
much cheaper stacked registered RAM on the A7V333. Don't ask me where
you would verify that info, as even the lostcircuits review of the
A7V333 doesn't mention the use of registered ram.
