4GB DDR3 1066MHz SODIMM Upgrade

This 4GB DDR3 1066MHz CL7 SODIMM module provides a straightforward memory upgrade for compatible laptops, notebooks and all-in-one systems. It uses unbuffered non-ECC chips rated at 1.5V standard voltage. The single 4GB stick suits users who need to replace a failed module or add capacity to an empty slot.

Check Your System Before Ordering

Verify that your device accepts DDR3 SO-DIMM memory at 1066MHz (PC3-8500) with CL7 latency and 1.5V operation. Confirm the motherboard supports unbuffered non-ECC modules and has a free 204-pin slot. Consult the manufacturer's qualified-vendor list or manual to ensure compatibility before purchase.

Thermals Noise and Power Draw

Standard 1.5V DDR3 modules run cool and silent because they have no moving parts. Power draw stays low during typical office and web workloads. No additional cooling is required beyond the laptop's existing thermal solution. The module operates within normal DDR3 thermal limits for everyday use.

Questions about this item

Does the 204-pin DDR3 SODIMM arrive as a single 4GB stick or do I need to buy a second module for dual-channel?

The package contains one 4GB module (1 x 4GB) so a second identical stick is required if your laptop supports dual-channel operation.

Should I pick the PC3-8500 CL7 1.5V version or a faster DDR3 SODIMM for my older notebook?

Choose this PC3-8500 CL7 1.5V module when your system specifies DDR3 1066; faster DDR3 will simply down-clock to 1066 MHz.

What does the 1066 MHz rating actually deliver once the SODIMM is installed in a laptop?

The memory runs at 1066 MHz (PC3-8500 bandwidth) with CL7 latency at the standard 1.5V, matching the speed your chipset expects.
