Compatible HP All-In-One Upgrade

This 4 GB DDR3 SODIMM is built for HP Pavilion All-In-One models 20-B304, 20-B309 and 20-B310. It adds 4 GB in a single 204-pin module running at 1600 MHz with CL11 timing. The kit targets owners of those specific all-in-one PCs who need a straightforward memory increase.

Replacing Slower Or Smaller Modules

The stick upgrades systems that shipped with lower-capacity or slower DDR3 SO-DIMMs. The jump is worth it when the platform supports up to 8 GB across two sockets and the current configuration leaves a slot free or uses smaller modules. Buyers who need more than 8 GB total cannot use this product.

Simple Slot Installation

Installation requires opening the all-in-one chassis, locating the SO-DIMM slot and pressing the module in until the clips engage. The 1.5 V unbuffered design matches the platform voltage. A common issue is the system failing to recognise the new stick if the slot is not fully seated or if the BIOS needs a reset.

Questions about this item

Will the 204-pin SODIMM fit the memory slots in my HP Pavilion All-In-One 20-B304, 20-B309 or 20-B310?

Yes, this module uses the standard 204-pin DDR3 SO-DIMM form factor that matches the two SODIMM sockets in those all-in-one models.

What is the correct way to seat the module so the 204 pins make full contact?

Insert the stick at roughly a 30-degree angle until the gold edge disappears, then press down firmly until both side clips click into the notches on the module.

When should I expect to replace this 4 GB stick in a system that supports up to 8 GB?

DDR3 memory has no scheduled replacement interval; swap it only if diagnostics report errors or you upgrade to the maximum 8 GB capacity using both sockets.
