A Closer Look

These kits have a no nonsense rectangular profile that is spiced up with angular lines and a clean mirror-polished finish.


The SPECTRIX design is simple but memorable, with a triangular light bar at the top center and "XPG" in white on each side.


The top of the light bar also features "XPG" in black. This kit is rated for either a 5000 MHz or 4800 MHz XMP profile at 19-28-28-46 and 1.6 V.


Branding on the XPG SPECTRIX D50 Xtreme is very minimalist, aside from the specification sticker, which I like.


The XPG SPECTRIX D50 Xtreme sticks are single-sided and use SK Hynix D-die ICs on a PCB with eight layers.

I like to weigh a stick from each kit I get as the difference in mass can be pretty drastic between kits. Mass is not the best indicator of cooling efficiency because material can matter, and of course, heat dissipation is reliant on surface area, not volume or mass. That said, it is still interesting to compare.


The XPG SPECTRIX D50 Xtreme comes in at 73.34 g on my scale, which is on the high end. The aluminium heat spreader is thicker than most. For height, the XPG SPECTRIX D50 Xtreme comes in at almost 44.61 mm with my calipers, which is right at the average of 45–50 mm.
