Our Take

Best for: Someone with an HP or other brand laptop who specifically wants RAM with a long manufacturer warrant

The HP S1 is a straightforward 8GB stick of DDR4 laptop memory running at 2666MHz. You'd pick this if you have a compatible laptop that needs more RAM for multitasking or light applications, and you want the reassurance of buying from a major brand like HP. What stands out here is the five-year warranty, which is longer than many competing modules, and the fact it's specifically tested for compatibility with a range of laptop motherboards. A notable limitation is its CL19 latency, which is not the fastest. This means while capacity and speed are adequate, response times in some tasks might not be as snappy as with lower-latency RAM. At this sale price, it's a fair value for the warranty and brand reliability, but the cost per gigabyte is still quite high compared to the broader market for 8GB DDR4.

Price Analysis

At $559.98, this is a 16% discount off the listed original price. The 90-day average price was about $600, so this is a bit lower than recent trends. However, for an 8GB DDR4 laptop memory module, this price point is significantly above what you would typically pay from other brands, making it a fair price only if the HP brand and extended warranty are specific requirements for you.

Common Questions

Is this RAM compatible with my Dell laptop?

It is compatible with many laptop brands, including Dell, as long as the motherboard supports DDR4-2666 memory. You should verify your laptop's specifications first.

Does this come as one 8GB stick or two 4GB sticks?

This is a single 8GB memory module (1x8GB). If your laptop has two slots, buying a matching stick later can enable dual-channel mode.

What does the 5-year warranty cover?

The warranty covers defects in materials and workmanship for five years from purchase. You would contact HP support for a replacement if it fails.
