This is possible. Either try 2.0.36/37 or 2.2.10 to be sure. However,
it could well be a hardware problem (cable length, termination, etc)

type free, and interpret that way:
<vulcan> schaefer:/usr/users/schaefer> free
total used free shared buffers cached
Mem: 63372 62484 888 36352 8288 14664
-/+ buffers: 39532 23840
Swap: 103844 2356 101488
This machine has 888k completely wasted memory (ie free memory, memory
never used by anything). However, as it has 8.2 MB of buffers and
14.6 MB of cached data, in case it is needed, it can free it and
thus the available memory for application is around 23 MBytes.
Linux uses automatically almost all the memory for disk cache.
