Patriot Memory Viper Steel SO-DIMM DDR4 1x32Gb PVS432G300C8S

Laptop format

Patriot Viper Steel SO-DIMM DDR4 is a shortened laptop format RAM. Also used in some minicomputers that use horizontal SO-DIMMs instead of vertical DIMM memory slots. In terms of bandwidth, DDR4 laptop memory is in no way inferior to a similar desktop one. But low-voltage DDR4L has a narrow 2x16-bit bus instead of 64-bit.

Factory auto overclocking

The Viper Steel SO-DIMM DDR4 series includes only individual modules from 8 to 32 GB, with a frequency of 2400 to 3200 MHz. Moreover, the intermediate version at 3000 MHz turned out to be the fastest. Because it has lower timings (delays) than 3200 MHz with standard JEDEC timings (CL18 vs CL22). In addition, two auto-acceleration profiles are sewn into it at the factory at once - with lower and higher timings, so that it will start up for sure.

For gaming laptops

Another thing is that most laptops, with the possible exception of flagship gaming ones, do not allow either activating the factory XMP profile or manually overclocking the memory (by increasing the frequency or lowering the timings). However, Patriot is positioning Viper Steel as a purely gaming solution. The 3000-MHz version works, by the way, at a slightly increased voltage - 1.25 V, against the typical 1.2 V for SO-DIMM DDR4. Fortunately, thin metal heatsinks are provided.
