4 GB DDR3 SODIMM for ProBook

This 4 GB DDR3 1600 CL11 SODIMM is built specifically for HP ProBook 6470b and 6570b notebooks. It arrives as a single unbuffered non-ECC module rated at 1.5 V with a 204-pin layout. The part number 1S6D31R804GB confirms JEDEC-standard compliance for a warranty-safe upgrade.

Suits owners of listed models only

This module suits owners of the two named ProBook models who need a direct drop-in upgrade. Buyers with other HP laptops, desktop PCs, mini PCs or NAS units should look elsewhere because the system-specific validation applies only to the 6470b and 6570b. The 1Rx8 organisation and CL11 timing are fixed for those platforms.

Speed locked to DDR3 1600 PC3-12800

The single specification that decides fit is the DDR3 1600 PC3-12800 rating. Your ProBook must accept this exact speed grade; a different DDR generation or a faster or slower DDR3 module will not work. No other voltage or timing option is supported by this part.

Questions about this item

How do I confirm the 4GB DDR3 1600 CL11 module is running at the correct speed after installing it in my HP ProBook 6470b?

Open Task Manager or a system information tool and verify the memory shows as 4GB DDR3 1600MHz PC3-12800 CL11 at 1.5V. The ProBook 6470b and 6570b will automatically configure the JEDEC-standard timings.

What comes in the package and do I need any extra parts to fit this 204-pin SODIMM into a ProBook 6570b?

The box contains one OWC 4GB 204-pin DDR3 1600 CL11 1.5V non-ECC SODIMM (part 1S6D31R804GB). No additional brackets, adapters or tools are required for the ProBook 6470b or 6570b memory slot.

Should I choose the 4GB 1Rx8 CL11 version or a different capacity for my ProBook 6470b upgrade?

This specific module is a single 4GB 1Rx8 DDR3 1600 CL11 stick. If your ProBook 6470b or 6570b has a free slot, adding this 4GB unit increases total memory by 4GB. Matching the existing module's speed and voltage ensures stability.
