Preface
Intended Audience
This manual is written for Digital customer service engineers and for self-
maintenance customers installing MS65A memories in VAX 6000 systems.
MS65A is the memory required by the VAX 6000 Model 500. MS65A
memories can be installed in VAX 6000 Model 200, 300, and 400 systems.
Document Structure
This manual uses a structured documentation design. There are many
topics, organized into small sections for efficient reference. Each topic
begins with an abstract. You can quickly gain a comprehensive overview
by reading only the abstracts. Next is an illustration or example, which
also provides quick reference. Last in the structure is descriptive text.
This manual has three chapters and two appendixes, as follows:
•Chapter 1, Overview, provides MS65A configuration rules and
information on ROM upgrades.
•Chapter 2, Unpacking and Installation, gives instructions on how
to unpack and install the MS65A.
•Chapter 3, Power-Up and Self-Test, describes the VAX 6000 self-test
with a focus on the MS65A memory modules.
•Appendix A, ROM Kit Order Numbers, shows the ROM kit numbers
for VAX 6000 systems.
•Appendix B, Interleaving, gives an overview of the interleaving
process for the MS65A.

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.
VAX 6000 MS65A MS62A
Both MS65A
and MS62A
Model 500 Yes No No
Models 200, 300, 400 Yes Yes Yes
This chapter describes the use of MS65A memory modules. Sections
include:
• MS65A Description
• Required ROM Upgrades
• MS65A Configurations
Overview 1–1

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.

1–2 VAX 6000: Installing MS65A Memories

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.
• Storage arrays are made up of two or four banks, either 155 or 299
DRAMs.
• ECC logic detects single-bit and double-bit errors and corrects single-bit
errors on 64-bit words.
• Memory self-test checks all RAMs, the data path, and control logic on
power-up.
• Quadwords, octawords, and hexwords can be read from or written to
memory.
• Memory is configured by the console program for 2-, 4-, 8-way or no
interleaving.
NOTE: The MS65A memory is required by VAX 6000 Model 500 and later
models since it implements the write-back cache protocol. However, it can
be used in Model 200, 300, and 400 systems.
Overview 1–3

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.

Table 1–1: Minimum ROM Level Required
Model 200 V5.0
Model 300 V6.0
Model 400 V3.00
Model 500 V2.00
NOTE: Without the correct console ROMs, the system may crash and battery
backup will not work correctly.
Before you install the MS65A memory modules, compare the ROM version
with the required version shown in Table 1–1. Example 1–1 shows a Model
400 system with 128 Mbytes of memory.
You can check the ROM level on the last line of the self-test display on each
processor module. Power up the system or issue an INITIALIZE command
to run self-test.
1This example is from a Model 400 system. The progress trace line does
not appear for Models 200 and 300.
2The ROM information appears in this format for a VAX 6000 Model
400. Examine the ROM version numbers at 2.
The ROM information appears in the following format for VAX 6000
Models 200 and 300:
ROM = 6.0 EEPROM = 2.0/6.0 SN = SG01234567
3These are examples of ROM revision mismatch messages indicating
that the CPU modules have different ROM versions. The ROMs need
to be updated so that the versions are all the same. Refer to Appendix A
for ROM kit order numbers for the ROMs specific to your system.
Overview 1–5

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.)

Model 200 Yes Yes Yes
If an MS65A memory module or a mix of memory modules is used in Model
200, 300, or 400 systems, ROMs must be upgraded. The console and
diagnostic ROMS on the processor modules are replaced so that MS65A
memory modules are supported.
Memory ROM-based diagnostics function with both types of memory
modules. However, the ROM-based diagnostic does not test functions of
the EEPROM on the MS65A memory module on VAX 6000 Models 200,
300, and 400.
Memory modules are configured after I/O adapter and processor modules.
Install memory modules next to vector processors first, then install
additional memories as follows:
1Install the first memory module in slot 9. Fill all available slots left to
right from slot 9 to slot 2.
2Install any additional memory modules right to left in available slots
from slot A to slot D.
NOTE: VAX 6000 systems with FV64A vector modules are an exception to
these configuration rules. Memory is first installed to the left of each vector
processor module, since only memory modules are permitted in these slots.
