G.Skill has a found a way to stand out among a crowded field of DDR4 RAM kits, which is no easy task these days—even sorting by kits that have RGB lighting (if you're into that) does little to narrow the field. So, G.Skill went and announced a double capacity memory line that crams more memory chips onto taller UDIMM modules.

"Up until now, 16 DRAM ICs per module was the maximum quantity of memory chips on standard UDIMM memory solutions. For this major technological limitation breakthrough, G.Skill worked together with the Asus ROG team to develop a brand new customized PCB solution that doubles per module capacity to 32 DRAM ICs," G.Skill says.
