[RndTbl] ECC - 8 chips?

[Trevor Cordes]

I'm doing some ECC RAM shopping on ebay (as per prev postings).

I came across something weird.  There's a stick showing up in various 
places that claims to be ECC but all pics (and the physical unit, I've 
confirmed) have only 8 (or 16) DRAM chips, not 9 or 18.

Does this make any sense to anybody?  Is this possible??

The stick is Kingston KTH-XW4400E6/2G

specifically says in "overview" it has "Error Checking and Correcting 
Technology"

Kingston has discontinued this part and it's hard to even find on the site 
anymore, but here's:

says x72 ECC
The equiv HP #'s they provide all show up on the net as 9 chip, so this 
Kingston stick should be ecc.

??? WTF?
