HP 15 Series compatible DDR4 kit

This 16 GB kit contains two 8 GB DDR4-2400 SO-DIMM modules built for HP and Compaq 15 Series notebooks including the 15-bs068tx, 15-bs0xx, 15-bs641tx and 15-bs642tx models. The unbuffered, non-ECC memory runs at 1.2 V with CL17 timing and uses 260-pin connectors.

Matched pair simplifies installation

The two modules are tested together so they operate as a matched pair, removing the guesswork of mixing single sticks. Each stick carries major-brand chips on a standard green PCB without a heat spreader, keeping the profile low for tight notebook slots.

Verify slot count and maximum capacity

These notebooks provide two SODIMM sockets and a 16 GB ceiling, so the kit fills every slot. Confirm your specific model number appears in the supported list before ordering, as other 15 Series variants may have different limits or pin layouts.

Questions about this item

Will the CL17 timing on these DDR4 2400 SODIMMs ever need adjustment or replacement?

The modules run at a fixed CL17 17-17-17 timing with no user-adjustable profiles, so no maintenance is required beyond keeping the notebook vents clear.

What limit appears first when the 16 GB kit runs at 2400 MHz continuously in an HP 15-bs series notebook?

The DDR4 2400 speed ceiling and the notebook’s two-slot 16 GB maximum are reached together; no higher frequency or capacity is supported.

How much heat or power does the 1.2 V unbuffered 2Rx8 kit add during all-day use?

At 1.2 V the modules draw minimal power and have no heat spreader, so thermal impact inside the chassis stays low.
