The memory in a DS20E follows the same specs as the memory that fits in a
DS10.
The DS10 won't accept higher density modules. The DS20E has 16 memory slots
and supports memory boards up to 256 MB.
The DEC supplied memory boards offer very little information but my DS20E
also has a few Toshiba boards:
PC100-222-620R
32M x 72 SDRAM
100 MHz CL2 ECC
The (128 MB) Micron board partno is: MT9LSDT1672AG-10Eb1
This is 100 MHz, synchronous, unbuffered, error correcting memory.
It operates at 3.3 V.
The CL 2 latency spec is important.
