8GB DDR4 SODIMM for HP Z4Y85AA#ABA

This 8GB DDR4 260-pin SODIMM module is built as a direct replacement for the HP Z4Y85AA#ABA part number. It targets laptop, notebook and all-in-one owners who need a straightforward memory upgrade without ECC or registered buffering.

CL17 timing at 1.20V standard voltage

The stick runs at DDR4 2400 (PC4-19200) with CL17 latency and the standard 1.20V DDR4 voltage. Its unbuffered, non-ECC design and lack of a heat spreader keep the profile slim for tight SODIMM slots in thin-and-light chassis.

Verify 260-pin DDR4 slot and maximum supported speed

Before ordering, confirm your system accepts 260-pin DDR4 SO-DIMMs and can operate at 2400MHz; some platforms down-clock automatically, while others may require a BIOS update or have a lower native ceiling.

商品問答

Does the DDR4 2400 MHz PC4-19200 interface cap real-world bandwidth below the rated 19200 MB/s?

The module runs at DDR4 2400 MHz with a PC4-19200 rating; actual throughput depends on the laptop's memory controller and any BIOS limits, so sustained bandwidth can be lower than the theoretical peak.

Will the 260-pin SO-DIMM fit my laptop's memory slot without a heat spreader?

Yes, the stick uses the standard 260-pin DDR4 SO-DIMM form factor and has no heat spreader, so it fits the same slots as the original HP Z4Y85AA#ABA module.

What is the correct way to seat the module, and what step do people often miss?

Align the notch with the slot key, insert at a slight angle, then press down firmly until both side clips click; the step most often missed is pushing until both clips engage fully.
