I have an AlphaStation 600/333 with 512mb of memory which is getting
alot of 'Corrected ECC Error in Memory during D-Cache fill' errors (37 in
the last hour). We reseated the memory but the errors are still occuring.
How do I interpret these errors? (ie what piece of hardware might
I need to replace? How do I map the Physical address or the error
to a board?)
The errors in messages look like:
vmunix: Machine Check error corrected by processor
vmunix: Physical address of error ffffff0016ffe19f Corrected ECC Error in
Memory during D-Cache fill
vmunix: Fill Syndrome = 0000000000000b00
vmunix: Single Bit error in Quadword 1 at bit<17> in a Data bit
vmunix: EI Address = ffffff0016ffe19f
vmunix: EI Status = fffffff0c4ffffff
vmunix: Interrupt Status Reg = 0000000100000000

Thanks for any information,
