Install RAM

The Silentwriter 1765 has two Single Inline Memory Module (SIMM) slots that support 72-pin with parity (36 bits) industry standard RAM SIMMs, available from many third party vendors. NEC recommends RAM speeds of 70 nanoseconds or faster. 1, 2, 4, 8, 16 and 32 MB SIMMs are available, and you can add up to 48 additional MB of RAM. The 1760 comes with 4 MB as standard equipment. The Silentwriter 1765 requires a minimum of 6 MB for network printing. To upgrade a 1760 to a 1765 you need to purchase and install at least 2 additional MB for a minimum of 6 MB.
