Compatible DDR3 SODIMM kit

This 8 GB kit contains two 4 GB DDR3 1066 MHz CL7 SODIMM modules built for the HP Pavilion dv4-1540us and dv4-1530br notebooks. It uses 204-pin unbuffered non-ECC memory rated at 1.5 V with 7-7-7 timing. The kit targets owners of those specific models who want to reach the 8 GB maximum supported by the platform.

Straightforward notebook installation

Installation requires opening the memory compartment, aligning each 204-pin stick with the slot, and pressing firmly until the retention clips engage. Common issues include inserting a module at an angle so it does not seat fully, mixing different speeds or voltages, and forgetting to remove the battery or AC power before starting.

Verify your exact model and slots

Confirm the notebook is a dv4-1540us or dv4-1530br and that both SODIMM sockets are free for the 2 x 4 GB configuration. The system accepts DDR3 1066 (PC3 8500) non-ECC unbuffered memory at 1.5 V. Do not order if your unit uses a different memory generation, voltage, or pin count.

Questions about this item

How can I confirm the 1066 MHz DDR3 memory is running at CL7 after installation?

Enter the system BIOS or use a tool such as CPU-Z; the SPD tab should show 1066 MHz and 7-7-7 timings at 1.5 V.

What is included in the package and what else is required?

The box contains two 4 GB 204-pin DDR3 SO-DIMM sticks; no additional parts are needed for the HP Pavilion dv4-1540us or dv4-1530br.

Should I choose the 8 GB kit or a different capacity for these notebooks?

The HP Pavilion dv4-1540us and dv4-1530br support a maximum of 8 GB across two sockets, so this 2 x 4 GB kit fills the limit.
