Simmtec, Inc 16MB SIMM 4M x 36 60ns DEC 54-23170-BA

SKU CH-QXT5-KAYV5

16 MB SIMM memory module with 4M x 36 organisation and 60 ns access speed

  • 16 MB capacity for legacy desktop upgrades
  • 4M x 36 organisation with parity support
  • 60 ns access speed for period-correct timing
  • New old-stock condition direct from supplier
  • DEC part 54-23170-BA for exact replacement match

Purpose and fit

This is a 16MB SIMM module organised as 4M x 36 with a 60ns access time. It is a new old-stock memory component for desktop systems that accept this specific form factor and timing. The DEC part number 54-23170-BA identifies the exact variant required by compatible hardware.

Who this suits

This module suits technicians repairing or upgrading legacy desktop boards that specify a 36-bit wide SIMM running at 60ns. It will not fit systems that require 72-pin SIMMs of a different bit width, faster access speeds, or larger single-module capacities. Buyers needing EDO, SDRAM or DIMM technology should look elsewhere.

Deciding specification

The 4M x 36 organisation combined with a 60ns rating is the single specification that determines whether this part matches the motherboard slot and timing requirements. Verify that the target system calls for exactly this configuration before purchase.

Questions about this item

What motherboard slot type is required for this 16MB SIMM 4M x 36 60ns module?

This module uses the 72-pin SIMM form factor, so the motherboard must provide a matching 72-pin SIMM socket.

Can this 60ns SIMM run in a system that originally shipped with 70ns memory?

Yes, the 60ns access time is faster than 70ns, so it will operate correctly at the slower timing the board expects.

How can I verify the module is recognised as 16MB after installation?

The system BIOS or POST screen should report the total installed memory increased by 16MB, confirming the SIMM is detected.
