I think I got a bad batch of memory for my PC164.  I'm attempting to
isolate 4 good simms out of the batch of 8 I bought.  At this point,
I'm pretty sure 2-3 of the batch of 8 I bought are bad; I just don't
know which ones yet.

Anyone know how to interpret ECC error messages from SRM?

Processor correctable error through vector 630.

Alpha 21164 CPU IPRs:
FILL_SYN: 0000000000002000  ISR:     0000000100000000

Processor detected single bit ECC error in Memory

The "EI_STAT" and "FILL_SYN" are consistent with any given
configuration of SIMMs but (sometimes) change when I swap them around.

Anyone know where this is documented?
