  • Page 11: Chapter 1 Overview

    Chapter 1 Overview MS65A memory modules are used in all VAX 6000 series systems. Model 500 systems require the MS65A. Earlier model systems can use the MS65A along with the MS62A memory modules. MS65A memory modules used in Model 200, 300, or 400 systems provide higher density memory modules with a capacity of up to 128 Mbytes per module.

  • Page 12: Ms65A Description

    1.1 MS65A Description The MS65A memory module is a metal-oxide semiconductor (MOS), dynamic random access memory (DRAM), which provides up to 128 Mbytes of data storage. The memory module is designed for use with the VAX 6000 through the XMI bus. Figure 1–1: MS65A Module BLOCK STATE MEMORY CONTROL...
  • Page 13 The MS65A memory module has the following features: • The memory module contains MOS dynamic RAM (DRAM) arrays; a CMOS memory control gate array that contains error correction code (ECC) logic and control logic; an EEPROM storage element; and an XMI interface known as the XMI Corner.

  • Page 14: Required Rom Upgrades

    1.2 Required ROM Upgrades VAX 6000 Models 200, 300, and 400 require CPU console and diagnostic ROMs at correct revision levels to use MS65A memory modules. Example 1–1: Checking ROM Levels #123456789 0123456789 0123456789 01234567# NODE # XBI D + XBI E + 128 Mb ROM0 = V3.00...

Before you install the MS65A memory modules, compare the ROM version with the required version shown in Table 1–1.

  • Page 16: Ms65A Configurations

    1.3 MS65A Configurations MS62A memory modules cannot be used in VAX 6000 Model 500 systems. MS62A and MS65A memory modules can be mixed in earlier models. (Figure 1–2 shows the order of placement of MS65A modules in the XMI backplane.) Figure 1–2: MS65A Configuration XMI CARD CAGE D C B A 9...

  • Page 20: Unpacking And Inspection Procedures

    2.1 Unpacking and Inspection Procedures MS65A memory modules are shipped in special packing cases to ensure maximum protection for each module. Each module should be inspected before installation. Table 2–1: MS65A Memory Modules Option Number Module Number Memory Size (Mbytes) MS65A-BA T2053-BA MS65A-CA...
  • Page 21 CAUTION: The MS65A module is static sensitive. ESD precautions must be taken when handling the module outside of its protective case. Use an antistatic wrist strap when handling the module. Use a Velostat Kit (CD kit number A2-W0299-10) to lay the modules on if many modules are removed and installed.

  • Page 22: Memory Installation In Systems Without A Vector Processor

    2.2 Memory Installation in Systems Without a Vector Processor Before adding memory modules, check the interleave set. If the default interleave is not being used, return the system to the default, so that new memory modules will be interleaved by the system. Install new memory modules in the appropriate slots.
  • Page 23 Before you add memory modules to a system, check to see that the system is set to the default interleave (see Example 2–1). If the interleave is not set to default, record the current setting and then set interleaving to default. Default interleaving is recommended because it provides the optimum memory configuration.

  • Page 24: Memory Installation In Systems With A Vector Processor

    2.3 Memory Installation in Systems with a Vector Processor Memory installation in a VAX 6000 Model 400 or later system with the FV64A vector processor requires a special configuration. Install new memory modules in the appropriate slots. Example 2–3: MS65A Installed in a Vector System #123456789 0123456789 0123456789 0123456789 0123456789 01234567# NODE # V- -P...
  • Page 25 Before you add memory modules to a system, the system must be set to the default interleave. In a system with vector processors, memory modules are first installed to the left of the FV64A vector modules. To add memory modules, perform the following steps: 1.

  • Page 28: Power-Up

    3.1 Power-Up Power up the system and check the self-test display for the new memory modules. Check the interleaving and any error messages. The self-test display shows that the console program configured the additional memory into the system. Example 3–1: Model 500 Power-Up #123456789 0123456789 0123456789 0123456789 012345# NODE # 128 Mb...
  • Page 29 Power up the system by turning the lower key switch to Halt and the upper key switch to Enable. Check the self-test display as follows: The memory modules are indicated by an M on the TYP line, as shown in Example 3–1. The memory module in slot 8 has been added. All three memories passed self-test, as indicated by plus signs (+) on the STF line.

  • Page 30: Self-Test Errors

    3.2 Self-Test Errors If an MS65A memory module fails self-test, the console runs an explicit memory test on the failing module. Any console error messages are displayed. The failing module is included in the memory configuration. Example 3–2 shows how a failing memory module can be excluded from the configuration.

  • Page 36: Ms65A Interleaving

    B.1 Overview Memory supports 2-, 4-, 8-way or no interleaving. Up to eight memory modules can be interleaved. Memory should be interleaved by using the default interleave rather than with console commands. Figure B–1: MS65A Interleaving 32 Mb 32 Mb 32 Mb 2-WAY INTERLEAVE SET (32, 32)
  • Page 37 Figure B–1 shows three examples of interleaving. The first is a two-way set (32, 32); two arrays of the same size are interleaved. The second two- way set (32 + 32, 64) consists of different size arrays. At the bottom of Figure B–1 is a system with a a four-way set made up of six modules and one 32 Mbyte module that is not interleaved.

  • Page 38: B.2 Console Commands

    B.2 Console Commands The SET MEMORY command is used for setting the interleave to a memory configuration other than the default interleave. The SET MEMORY command does not change memory interleaving; it just modifies the memory configuration in the EEPROM. NOTE: It is not advisable to use console commands to interleave memory modules, but occasional customer use will warrant overriding the original console setting of the interleave.
  • Page 39 The system is initialized to put the new memory interleave into effect. The SHOW MEMORY command displays the configuration set in NOTE: Refer to Chapter 5 of the VAX 6000 Series Owner’s Manual for detailed information on the SET MEMORY and SHOW MEMORY commands.
