8GB DDR3 SODIMM kit for Compaq laptops

This 8 GB kit contains two 4 GB unbuffered DDR3-1333 SODIMM modules rated at CL7 with 1.5 V operation. It is built for the Compaq Presario CQ57-489CA, CQ57-489WM and G42-478TX models that accept 204-pin memory.

Suits owners of the listed Compaq models needing

The kit matches the two-slot, 8 GB limit documented for these notebooks. It is not for systems that require ECC or registered DIMMs, laptops with only a single memory slot, or owners who need capacities beyond 8 GB.

204-pin DDR3-1333 CL7 specification decides fit

The modules run at PC3-10600 speed with 7-7-7 timing and 2Rx8 organisation. If the target notebook demands a different voltage, pin count, speed grade or latency, this kit will not be compatible.

Vragen over dit artikel

Will the 204-pin SODIMM modules need replacement if I later upgrade the laptop's memory capacity?

The kit provides 8 GB across two slots. If the notebook supports more than 8 GB you would replace both sticks with higher-capacity modules.

What limits sustained performance of the CL7 1333 MHz timing?

The memory controller in the Compaq Presario CQ57 or G42 series sets the maximum stable frequency and latency the modules can maintain.

How much heat and power do the 1.5 V unbuffered sticks produce during all-day use?

Standard DDR3 SO-DIMMs at 1.5 V draw modest power and run warm but not hot; no heat spreader is fitted.
