I'm pretty sure the IPX needed 33 bits as well.

LCA based machines need 36 bits, so Multia/AXPpci33. The service docs for
the AS200 say
* The system requires 72-pin parity SIMMs that have an access time of 70
36 bits definitely runs in AS200, that is what I have in one we have at

Yup, same experience here for Alpha.
