Compatible Toshiba Satellite upgrade

This 8 GB kit (2 × 4 GB) is built for Toshiba Satellite A505 models listed in the compatibility table. It uses 204-pin DDR3 SO-DIMM modules running at 1066 MHz with CL7 timing. The memory is unbuffered, non-ECC and operates at 1.5 V. Installation is a direct drop-in for the supported laptops.

Buyers needing ECC or higher speeds should look

The modules are non-ECC and unbuffered, so they will not meet requirements for error-correcting or registered memory. Speed is fixed at DDR3 1066 (PC3 8500); systems that demand faster DDR3 or a different generation cannot use this kit. Capacity is limited to 8 GB total across two slots.

204-pin DDR3 SO-DIMM form factor decides fit

Only laptops that accept 204-pin DDR3 SO-DIMMs at 1.5 V can use these modules. The kit will not work in desktops, in systems keyed for other DDR generations, or in boards that require ECC or registered DIMMs. Verify the laptop model against the supported list before purchase.

Questions about this item

How can I verify the 8GB kit is running at 1066 MHz after installing it in my Toshiba Satellite A505?

Open Task Manager or CPU-Z and check the memory tab; it should report 1066 MHz (PC3-8500) with CL7 7-7-7 timings at 1.5 V.

What is included in the package and do I need any extra parts for my Satellite A505?

The box contains two 4 GB 204-pin DDR3 SODIMM sticks; no additional components are required for the listed Satellite A505 models.

My Satellite A505 has two slots — should I buy this 2 x 4 GB kit or a single 8 GB module?

The 2 x 4 GB kit fills both slots for dual-channel operation, which the A505 chipset supports, giving better bandwidth than a single 8 GB stick.
