  • 512 MB capacity supports multitasking in legacy ThinkPad models
  • 266 MHz PC2100 speed matches original system bus requirements
  • 200-pin SoDIMM form factor fits A31, A31p, R32 and T30 slots
  • Non-parity DDR SDRAM ensures stable operation without error-correction overhead

IBM ThinkPad DDR SDRAM upgrade

This 512 MB module is built for IBM ThinkPad A31, A31p, R32 and T30 systems that take 200-pin SoDIMM DDR SDRAM. It runs at 266 MHz PC2100 with non-parity operation, matching the factory specification for those Pentium 4-M notebooks.

512 MB capacity and PC2100 headroom

The single stick delivers 512 MB, which covers the maximum supported slot size for the listed models. It will not suit laptops that require faster DDR speeds, larger per-slot capacities or a different pin count.

Questions about this item

Will this 200-pin SoDIMM work with the existing memory in my ThinkPad T30?

It matches the PC2100 266MHz specification used by the T30, so it will run alongside the original modules at the same speed.

How can I confirm the 512MB module is recognised after installation?

Boot the ThinkPad and check the BIOS memory count or the system properties in Windows; both should show the additional 512MB.
