4GB DDR3L 1600 SODIMM for HP ProBook

This 4GB module runs at 1600 MT/s with CL11 latency and 1.35V operation. It uses a 204-pin DDR3L Non-ECC SODIMM form factor. The single-rank 1Rx8 design meets JEDEC and ROHS standards.

Suits owners of HP ProBook 650 G1 or 655 G1

Buyers needing ECC error correction should look elsewhere. Systems requiring registered or buffered memory cannot use this unbuffered module. Laptops limited to lower DDR3L speeds may not gain the full 1600 MT/s rate.

204-pin DDR3L SODIMM form factor

The 204-pin DDR3L SODIMM interface determines physical and electrical compatibility. Only devices accepting this exact module type can install it. Verify the slot specification before purchasing.

Questions about this item

Will this 204-pin DDR3L 1600 module work if I keep the existing 4GB stick in my ProBook 650 G1?

Yes, it is compatible with HP ProBook 650 G1 and 655 G1 and runs at 1.35V CL11, so it will pair with the factory module.

How can I confirm the 1Rx8 module is running at the correct 1600 speed after I install it?

Open Task Manager or BIOS and verify the memory shows DDR3L 1600 (PC3L-12800) at CL11 latency.

Does the single 4GB SODIMM come with any tools or a heat spreader, or must I buy them separately?

The upgrade consists of the memory module only; no tools or heat spreader are included.
