HyperX, Kingston's elite gaming division, today launched new Impact DDR4 SO-DIMM offerings with capacities that span up to 64GB. 

HyperX's announcement points to high-capacity kits that could be the best RAM for enthusiasts needing large amounts of memory on their notebooks or small form factor PCs.

Impact memory modules are equipped with the brand's Plug N Play feature that automatically sets up the memory to run at the advertised frequency without any manual tweaking. Compatibility-wise, Impact memory modules should play nicely on both AMD Ryzen and Intel platforms.

HyperX is selling the new single-rank 16GB Impact stick as a single module or in a dual-channel configuration. The frequencies range from DDR4-2400 to DDR4-3200 with CAS latency values between 15 and 20. Regardless of the frequency, the memory modules only require 1.2V to operate smoothly.

The single modules retail between $77 to $95, depending on the frequency. The 32GB (2x 16GB) packages start at $153 and top out at $190.

HyperX says it factory tests every Impact DDR4 SO-DIMM memory kit to assure that it performs at the advertised speed without hiccups. The vendor also backs them with a limited lifetime warranty.

    The article says, "with capacities that span up to 64GB."

    But in the specifications table below that, the only capacity offered is 16 GB. There are some 2x16 GB offerings, but none of those are even 4x16 = 64, let alone 1x64.

    To me, a capacity of 64 GB means a single 64 GB DIMM. Perhaps a clarification is in order?
