I think this message is bogus, but there is indeed somthing bad with memory.
I have 2x pairs of different labels (should be compatible). IBM and 
Kingston marked

I mounted them interleavd (old SparcStation habit).
0 - 2 Type A
1 - 3 Type B

This is what used to work, but started to fial.

First, I tried swap 0 with 3. Still fail. Still put at DIMM 0! so it is 
not the module?

I remove all memory, I get a no memory error. Fine.

I put IBM in Slot 0: fine.
I put IBM in Slot 0 + 1: fine

I put IBM in Slot 0 + 1, Kingston in Slot 2: error
I put IBM in Slot 0 + 1, Kingston in Slot 3: error (same module, just moved)

I thus suspect of Kingston "A" module that causes issues independently 
of Slot 2 or Slot 3!
Thus I put module Kingston "B" in Slot 2

At this point I suppose all Kingston marked modules are an issue? Or 
Slot 2 and 3 are problematic.

I put IBM in Slot 2 + 3: fine

This means that at the basic all slots are fine!

If I put Kingston in 0 + 1: fail!
Thus I put Kingston A in Slot 0: fail
Thus I put Kingston B in Slot 0: fail


To go 100% sure I borrowed two sticks from another machine and all 4 
modules get recognized, full memory capacity and system boots, runs, 
compiles: works

I can desume that my T1 doesn't like the Kingston modules anymore or the 
BOTH failed in a month?

If I hadn't tested this system a month a go and personally installed 
OpenBSD and did even some stress tests, I wouldn't believe this.
