PMI memory error

So the memory board might be bad. When the 11/83 runs memory tests the 
1mb board (of course the one that's fixed to run on Q bus systems) fails 
out with:

Testing in progress - Please wait
Memory Size is 3072 K Bytes
9 Step memory test
   Step

Error 47
Memory CSR Error

See troubleshooting documentation


Error PC = 173354       PCR page = 14   Program listing address = 014354

R0 = 060002     R1 = 100000     R2 = 172136     R3 = 172346
R4 = 100000     R5 = 000000     R6 = 172300     Par3 = 102000

It's there and I can see it in the memory map:
Memory Map

Address    address      K Bytes    address      type    type

10000000 - 13777776     1024       17772136     ECC     PMI

But setting any CSR seems to fault it. Drat.

Any thoughts?
