HP ProBook 4720S Memory Kit

This 8 GB kit contains two 4 GB DDR3 SODIMM modules built for the HP ProBook 4720S notebook. It restores dual-channel bandwidth when both slots are populated. The unbuffered, non-ECC design matches the original specification for mainstream mobile workloads.

204-Pin SO-DIMM Build

Each stick uses a standard 204-pin edge connector that slots directly into the laptop memory sockets. Low-profile chips sit flush without a heat spreader so the module clears tight chassis clearances. Gold contacts resist oxidation through repeated thermal cycles in portable use.

Upgrade From 4 GB Single Channel

Replacing a single 4 GB module with this pair doubles capacity and enables dual-channel operation for measurable throughput gains. The jump is worthwhile when multitasking causes frequent paging or when the current stick runs at a slower CAS latency. Buyers needing 16 GB total or ECC protection should look elsewhere.

商品問答

What does the DDR3 1333 (PC3-10600) interface mean for real-world speed?

The kit runs at DDR3 1333 with a PC3-10600 rating and CL7 7-7-7 timings at 1.5V, delivering the standard peak transfer rate for that specification.

Will the 204-pin SODIMM sticks fit inside my HP ProBook 4720S?

Yes, each module is a 204-pin DDR3 SO-DIMM without a heat spreader, matching the slot and low-profile clearance of the ProBook 4720S.

How do I install the two 4 GB modules, and what step do people often miss?

Power off, remove the battery, open the memory door, insert both sticks at the same angle until the clips click, then replace the door and battery before booting.
