I don't know, but as the alpha has been 64bit system from very
begining,
i find it very hard to believe that i would have such limits?
  
This is actually my first alpha which have more than 512MB memory, so i 
am bit lost (not to mention that the system is 'partitionable' arch :)

It's very hard me to verify this kind of setup as i have three boards  
and 4GB/board. I don't think i can just rip of half of the memory from 
the board or can i? I opened one and saw 80pin SIMMs (hey, it's digital 
you know - 80pin is very familiar from VAXen and DECstations :)
From the amount (forgot to calculate exact count) those are 128MB
SIMMs.

 B      7    4096 Mb   00000002 00000000      4-Way      0

Makes me wonder that there are actually 4x1GB banks in one board as the 
odd one is claimed to be 4-way interleaved.
   
So can anyone verify that i can just rip of half the memory and test
with 2GB?

And we're talking about GS140, which is 6/525. 8400 is supposed to be
5/440? Gneration difference with CPUs and stuff?
