DDR1

  • Module Formats: DIMM, SO-DIMM and Micro-DIMM
  • Capacities: 128MB to 512MB
  • Voltage: 2.5V
  • Operating Temperatures: 0°C to 70°C or −40°C to 85°C

DDR1 Support for Established Platforms

AMP supports hard-to-find DDR1 memory for established and long-life platforms that cannot be economically redesigned around a newer memory generation. Module availability is reviewed against the original part number, form factor, capacity, data rate, rank, organization, ECC, buffering, voltage and environmental requirements.

Capacity, data rate, rank, organization, component layout, ECC and buffering must be reviewed against the original part number and host platform.

Configuration note: DDR1 availability varies by module format, capacity, data rate, rank, organization, ECC, buffering, temperature grade and original component configuration. Optional conformal coating, heat sink and underfill are available for selected configurations. Confirm the exact part with AMP before qualification.

Frequently Asked Questions

What DDR1 module formats does AMP support?

AMP supports 184-pin DDR1 DIMM, 200-pin SO-DIMM and 172-pin Micro-DIMM configurations. Exact availability varies by module type and part number.

Are ECC and non-ECC DDR1 modules available?

Yes, depending on the module format and configuration. ECC modules are 72-bit wide, while non-ECC modules are 64-bit wide. Confirm buffering, organization and host compatibility for the required part.

What DDR1 capacities and speeds are available?

Capacity and data-rate availability depends on module format, organization, rank and original component configuration. AMP can review DDR-200, DDR-266, DDR-333 and DDR-400 requirements using the original part number and platform details.

Are commercial and industrial DDR1 options available?

Yes. Commercial-temperature options operate from 0°C to 70°C, while industrial-temperature options operate from −40°C to 85°C. Availability varies by configuration and should be confirmed by part number.

What information should I provide for a DDR1 replacement?

Provide the original part number, host or system model, module format and pin count, capacity, speed, voltage, ECC and buffering requirements, rank and organization, operating temperature, annual volume and expected program life.

Need Help Selecting a DDR1 Module?

Share the module format, pin count, capacity, speed, ECC and buffering requirements, operating grade and host platform so AMP can review compatible options.
