4x4GB DDR3-1066 SODIMM kit

This kit provides four 4 GB SODIMM modules rated at 1066 MHz with CL7 timing. The unbuffered, non-ECC memory operates at 1.5 V and uses a 204-pin DDR3 interface. It is intended for notebooks or small-form-factor systems that accept PC3-8500 SO-DIMMs.

Who this suits and who it does not

The 2Rx8 organisation works in platforms that support dual-rank SO-DIMMs at this speed. Buyers whose hardware requires single-rank modules or a lower voltage standard should look elsewhere. Systems limited to a maximum of 4 GB total memory will not benefit from the full kit capacity.

Deciding specification — 1066 MHz DDR3 SO-DIMM

The modules run at 1066 MHz (PC3-8500) with CL7 latency on a 204-pin DDR3 SO-DIMM form factor. Verify that the target platform lists this exact speed, voltage and pin count before purchase.

Questions about this item

How much power does the 1.5V DDR3-1066 kit draw when the system runs all day?

The modules operate at 1.5V, the standard voltage for DDR3 SODIMMs, so power draw stays within normal laptop limits during continuous use.

What must my laptop already have to accept these 204-pin SODIMMs?

Your laptop needs four free DDR3 SODIMM slots that support 1066 MHz PC3-8500 unbuffered non-ECC memory at 1.5V.

Will the CL7 timing slow down if I keep my existing slower DDR3 sticks installed?

Yes, all memory in the system will run at the slowest installed module speed or the processor capability, so mixing with slower sticks reduces overall performance.
