HP ProBook Compatibility

This 8 GB kit contains two 4 GB DDR3-1333 SO-DIMM modules built for HP and Compaq ProBook 4435s, 4436s, 4520s, 4525s and 4530s notebooks. It targets owners of those specific models who want to reach the maximum supported memory using matched parts.

DDR3 SO-DIMM Limits

The 204-pin DDR3 interface runs at 1333 MHz with CL7 timing and 1.5 V unbuffered operation. A 32-bit operating system will only address 4 GB, so a 64-bit OS is required to use the full 8 GB. The two SODIMM sockets in these ProBooks cap total memory at this kit's capacity.

Pre-Purchase Checks

Confirm your ProBook model number matches the listed series exactly before ordering. Verify the installed operating system is 64-bit to avoid the 3.5 GB recognition limit. Ensure both memory slots are free or that you are replacing the existing pair, as the kit is designed for a two-module configuration.

Questions about this item

Should I pick the 2x4 GB kit or a single 8 GB module for my ProBook 4435S?

This kit provides two 4 GB SODIMMs that fill both slots in the ProBook 4435S, 4436S, 4520S, 4525S and 4530S for full dual-channel bandwidth.

Will DDR3-1333 actually run at 1333 MHz in my laptop?

The modules are rated PC3-10600 at 1333 MHz with CL7 timing; the ProBook chipset will clock them at that speed provided the BIOS supports the 1.5 V JEDEC profile.

Does the 204-pin DDR3 SO-DIMM interface limit total memory to 8 GB?

The ProBook 4435S, 4436S, 4520S, 4525S and 4530S each have two DDR3 SO-DIMM sockets; a 64-bit OS can address the full 8 GB from this kit, while a 32-bit OS may see only 3.5 GB.
