System-Specific DDR4 SODIMM

This 8 GB DDR4 2400 CL17 module is built for HP 20-c450ng, 20-c453ng, 22-c0001ne, 22-c0001nl and 22-c0004na laptops. It fits the 260-pin SODIMM slot and runs at the standard 1.2 V without ECC or buffering.

Thermals, noise and power

The unbuffered DRAM operates at JEDEC 1.2 V and has no heat spreader, so it adds negligible heat and zero acoustic noise. Power draw stays within the laptop’s original memory budget during normal multitasking workloads.

Upgrade context

Replacing a 4 GB stick or filling an empty slot doubles capacity for heavier browser tabs and office suites. The jump is worth it when the system currently swaps to disk; it will not help if the CPU or storage is already the bottleneck.

Questions about this item

How do I install this 260-pin DDR4 SODIMM in my HP 20-c450ng, and what step do people often get wrong?

Power off the laptop and disconnect the battery if accessible. Open the memory compartment, align the notch on the module with the slot key, insert at an angle, then press down firmly until the side clips click. The step people miss is pressing hard enough to fully seat both clips; a loose module causes boot failures.

What maintenance or replacement will this 8GB DDR4 2400 CL17 module need later?

No scheduled maintenance is required for this non-ECC unbuffered SODIMM. It has no heat spreader, so keep the laptop vents clear to avoid thermal throttling. Replacement is only needed if a memory error appears or you want more capacity; the limited lifetime warranty covers defects.

What limit shows up first under sustained use with this 1.2V 2Rx8 CL17 memory?

The CAS latency of CL17 at DDR4 2400 sets the timing floor, so sustained workloads hit latency-bound throughput before bandwidth saturates. The 1.2V JEDEC voltage also means no overclocking headroom; thermal limits of the laptop chassis will throttle the module before the memory itself fails.
