So they have an extra parity bit...

a sticker on one of chips that has '3163667/23BT S023039 64MB'. I was told
they came out of a Compaq Proliant server (don't know the model). All of
this seems to indicate they _should_ be compatible with the XLTs.

One XLT366 is able to post AlpahBIOS with either four or eight of these
SIMMs installed, and the memory count is either 256MB or 512MB
respectively. Yet, when I boot Linux, I get an endless stream of ECC
errors and corrections, slowing the system down so badly Linux is never
able to fully boot. AlphaBIOS version is 5.66.

...but ECC requires more than one:)

Lastly, I tested them in a Sparc LX (which also takes 72pin parity
SIMMs). I installed the maximum of six SIMMs (384MB), and it was able to
see the maximum 96MB it supports. Furthermore it was able to boot and run
Linux without issue. It appears that as long as the SIMMs are not fully
utilized they work fine. When fully utilized, they just don't work.

As I said, parity != ECC.
