how could print calls fix the problem? I am working completely
remotely. :((
The suggestion to jiggle the DIMMs seems appropriate again. :)
So when the machine claims to have only 12GB of RAM, I see with lshw(1):

I am only curious why the product: field is not empty but rather
shows type of the actual module. All eight DIMMS are same Corsair
2GB RAM modules (sorry, I think I wrote Kingston previously but is
not true). Moreover, the modules are at 266MHz and not on 333MHz,
the board would take only 6 modules at 333MHz. So lshw should report
-2700 instead of -3200. Inspecting their serial numbers in the
invoice I see:
340540434
340540435
330541284
330541283
330541282
330541281
330541280
330541279
Yes, 2 are different. I guess your question would be whether those 2
unseen DIMMS are the first two serial numbers ... I can't say now
but definitely when only 8 GB of RAM are detected the problem would
include additional two DIMMs.
So, what would you recommend now. To flash from BIOS 1.20 to 1.50
and pray? ;-)
