SKU CH-SX3S-H29RQ

8 GB DDR4 2400 CL17 1.2 V SODIMM for HP ProBook 470 G3, 470 G4, 640 G2 and 645 G3

  • Capacity8GB
  • Type260-Pin DDR4 SO-DIMM
  • SpeedDDR4 2400 (PC4 19200)
  • CAS LatencyCL17
  • Timing17-17-17
  • Voltage1.2V
  • 8 GB capacity expands multitasking headroom for ProBook workloads
  • DDR4 2400 speed matches factory spec for 470 G3 and G4
  • CL17 latency at 1.2 V keeps power draw low in thin chassis
  • 260-pin SODIMM form factor fits 640 G2 and 645 G3 slots directly
  • Single 8 GB module leaves second slot free for future 16 GB max

Targeted DDR4 SODIMM Upgrade

This 8 GB DDR4 2400 MHz SODIMM is built for HP and Compaq ProBook 470 G3, 470 G4, 640 G2 and 645 G3 notebooks. It delivers a direct memory increase for users whose workloads exceed the factory configuration.

Replacing Slower or Smaller Modules

The module upgrades from lower-speed DDR4 or 4 GB and 8 GB sticks that limit multitasking. The jump is worth it when the system shows high memory pressure during typical business applications.

Fits Two-Slot ProBook Chassis

The 260-pin unbuffered non-ECC stick occupies one of two SODIMM slots and runs at 1.2 V without a heat spreader. It leaves the second slot free for a matching module to reach the 16 GB platform maximum.

Questions sur cet article

Will the 260-pin DDR4 SO-DIMM fit the memory slot in an HP ProBook 470 G4?

Yes, this 260-pin DDR4 SO-DIMM is listed as compatible with the HP ProBook 470 G4 and other ProBook models including the 470 G3, 640 G2 and 645 G3.

What is the correct way to seat this SODIMM so it does not appear loose after installation?

Insert the module at an angle into the 260-pin slot until the gold contacts are fully hidden, then press down evenly until the retention clips on both sides snap into the notches on the PCB.

Will this 8 GB DDR4 2400 CL17 module need any firmware updates or pairing to keep working in a ProBook 640 G2?

No firmware or pairing is required; the module is unbuffered non-ECC DDR4 that operates at 1.2 V with standard JEDEC timings, so it runs without software maintenance for the life of the laptop.
