2GB DDR2 SODIMM for Toshiba Satellite

This 2GB DDR2 800 SODIMM is built for Toshiba Satellite L505D-SP6983C and L505D-SP6983R notebooks. It uses a 200-pin SO-DIMM form factor with CL6 timing at 1.8V. The single module provides a straightforward capacity increase for compatible legacy systems.

Low-voltage DDR2 operation

Running at 1.8V without a heat spreader, the unbuffered module draws minimal power and produces little heat in normal use. The non-ECC design keeps latency tight at 6-6-6 timings. No active cooling is required for standard notebook workloads.

Single-stick upgrade kit

The package contains one 2GB memory stick backed by a limited lifetime warranty from the manufacturer. Product appearance may vary from the reference image. Buyers needing more than 2GB or requiring ECC support should verify their system specifications before ordering.

Questions about this item

How do I install the 200-pin SODIMM into the Satellite L505D-SP6983C?

Power off the laptop, remove the battery, open the memory compartment, align the notch on the module with the slot key, insert firmly until seated, then press down until the side clips lock.

What maintenance or replacement will the CM256646400SO need later?

No scheduled maintenance is required; keep the contacts clean and ensure the laptop vents stay dust-free so the 1.8 V module runs at its rated 800 MHz without thermal throttling.

What limit appears first under sustained load with this DDR2-6400 stick?

The CAS latency of CL6 and the fixed 1.8 V voltage set the bandwidth ceiling; prolonged heavy use will hit that timing wall before any thermal limit on the unbuffered 2Rx8 chips.
