They used to build boxes with cheap no-ECC, no-parity DRAM
and had their fingers blown off by people who started counting
the difference between line BER and e2e checksum failures,
particularly on faster boards.

Now they use well-built ECC SDRAM in general, and retain
their fingers.  AFAIK they don't forbid anyone from going
out and acquiring el-cheapo RAM from other suppliers.

A bit-error in a patricia tree can be really yucky.
