14.3.20 DEC/VAX 7000/10000 Memory interleaving restriction

A problem with the LEVI-A chip on early CPU modules results in the following memory

conﬁgurations only being allowed.

• 1, 2 or 4 of the same size modules, up to max of 512 MB

• 1 x 128 MB + 2 x 64 MB modules

• 1 x 256 MB + 2 x 128 MB modules

An unsupported conﬁguration results in the following console message at boot time:

"Invalid memory interleave—boot disallowed".

Fixed on VAX 7000/10000 by FCO 7xxx-F004 (see Section 13). No ﬁx for DEC 7000/10000s

at present.

NOTE: Some VAX 7600 CPU modules (E2045) may not be at the revision they claim to be.

See BLitz TD 1947.

14.3.21 RZ57s on ALPHA platforms

RZ57s on DEC 7000 systems must be rev. D01 (rev. 6000 ucode) or above. Lower revs. can

suffer undetected write faults. An EQ kit has been proposed, but not for an FCO. Customers

are expected to buy it!

14.3.22 RF73s in VAX 7600 SF73LA, cable problem

The ﬂex cable at the rear of the RF73 can get damaged if the drive is positioned too far back

on it’s skid plate. The drive should be mounted using the third set of holes from the front.

14.3.23 VMS gains time

Some VAX 7000 systems experience a problem where VMS system time gains by more the

9 sec per day (the quoted tolerance). This is ﬁxed by a REV N06 KA7AA (E2045-AA) CPU

module. If module can’t be replaced, customer can run a batch job to do SET TIME every

12 hours.
