4 GB DDR3 1066 SODIMM for HP G72 notebooks

This 4 GB DDR3 1066 MHz module is built for HP and Compaq G72 series laptops such as the G72-B54Nr, G72-B57Cl, G72-B60Us and G72-B63Nr. It uses a 204-pin SO-DIMM form factor and runs at 1.5 V without ECC or buffering. The kit contains a single stick for straightforward slot population.

CL7 timing and 1066 MHz speed headroom

Rated at PC3-8500 with 7-7-7 CAS latency, the memory operates at 1066 MHz on platforms that support DDR3-1333 but downclock the bus to 1066 MHz depending on the processor. A 32-bit operating system recognises up to 4 GB while a 64-bit OS allows the platform maximum of 8 GB across two slots. Installing 4 GB on a 32-bit system may show 3.5 GB or less due to address-space allocation.

Unbuffered 2Rx8 design with major-brand chips

The stick uses a 2Rx8 organisation with major-brand DRAM components and no heat spreader, keeping the profile low for tight notebook chassis. Compatibility is guaranteed for the listed G72 models and extends to a wide range of G72-100 through G72-250US variants. Appearance may vary from the reference image.

Questions about this item

Will this CM512648500SODRH DDR3 1066 module run correctly alongside an existing PC3-8500 stick in my G72?

Yes. The module is rated DDR3 1066 (PC3-8500) with CL7 7-7-7 timing at 1.5 V unbuffered, matching the factory spec for the G72 series so it will operate at the same bus speed as the original memory.

How can I confirm the 4 GB stick is detected at the correct 1066 MHz speed after installation?

Open Task Manager or CPU-Z and check the memory tab; it should show 4 GB running at 1066 MHz (PC3-8500) with CL7 timings.

Does the package contain only the CM512648500SODRH SODIMM or are tools and a heat spreader included?

The box contains one 204-pin DDR3 SODIMM module only; no heat spreader, screwdrivers or additional accessories are supplied.
