XLR8 Gaming EPIC-X RGB is PNY's lit-up DDR4 desktop line, sold from single sticks up to four-module sets and covering a moderate spread of speed grades under one name. Every kit in the family carries the RGB bar; none of it is sold in a plain version.
1×8GB at 3200 MT/s CL16 gives 8GB in this listing, and a four-stick set in this family asks more of a board's memory controller than a two-stick kit of the same total capacity does — worth knowing if you're filling every slot at once rather than starting from an empty board.
This is DDR4 UDIMM for standard desktop boards. Rated speed only applies with the board's XMP profile selected in firmware; left on defaults, the kit runs at a slower baseline.
