It does indeed look to be the case. I actually ran into this once. I was 
using an IBM desktop PC that had only 1 GB of RAM, we had on order 
memory from IBM for it, but the IT guy had another pair of 512MB ram 
that was originally destined for a CAD workstation, but for whatever 
reason remained unused. I asked him about it, he shrugged and said I 
could try it, but he didn't think it would work, since the memory was 
designed for the workstation. I tried it, and the PC refused to boot.

I'm pretty sure after what I read about high density ram (I looked at 
some other info on the subject besides the eBay page, also strange, our 
firewall doesn't block eBay...) that the ram for the CAD station was 
indeed high density. I suppose the other alternative is that it was 
registered memory.

Yep. do the numbers on the chips indicate a 128x4 configuration (hint, 
you could probably Google the number on the chip and get a datasheet...)

According to the Wikipedia article on DDR Samsung K4H510438D-UCCC would 
be high density.
