ibm 326m dual core opteron misreporting memory ?

Hi,

I have two IBM boxes, both with 16 Gig of memory.

On the current one, this is reporting correctly ,i.e.

Good_BOX> free -m
             total       used       free     shared    buffers     cached
Mem:         15709      15293        416          0        172      10146
-/+ buffers/cache:       4974      10735
Swap:        15939        224      15715


and;

Good_BOX> more /proc/meminfo
        total:    used:    free:  shared: buffers:  cached:
Mem:  16472915968 16036270080 436645888        0 180789248 10707410944
Swap: 16713449472 235053056 16478396416
MemTotal:     16086832 kB
MemFree:        426412 kB

and on the incorrectly reported memory, I see

Bad_Box> free -m
             total       used       free     shared    buffers     cached
Mem:          3510        139       3370          0         16         49
-/+ buffers/cache:         73       3436
Swap:         9993          0       9993

and

Bad_Box> more /proc/meminfo
        total:    used:    free:  shared: buffers:  cached:
Mem:  3681280000 146874368 3534405632        0 17100800 52379648
Swap: 10478985216        0 10478985216
MemTotal:      3595000 kB
MemFree:       3451568 kB

when I boot to bios on both boxes, then show the same memory. The other
difference between the boxes is the processor, ie

Good_BOX> more /proc/cpuinfo
processor       : 0
vendor_id       : AuthenticAMD
cpu family      : 15
model           : 37
model name      : AMD Opteron(tm) Processor 252
physical id     : 204

and

Bad_Box> more cpuinfo
processor       : 0
vendor_id       : AuthenticAMD
cpu family      : 15
model           : 33
model name      : Dual Core AMD Opteron(tm) Processor 265
stepping        : 2
cpu MHz         : 1795.553
cache size      : 1024 KB

So, is the memory misreporting, something to do with the dual core, or
is there something else I should be looking at.

Thanks for any advice.
