I know a large contingent of the community will write off this kit because of the focus on RGB. I think that's fine, and everyone is allowed to have their own opinion. However, the fact remains that RGB LEDs are a popular feature, and the XPG SPECTRIX D60G could be a fantastic option for those in the market for it. Even in this category, they are not perfect. The seam along the top of the sticks where the two halves of the diffuser meet is more noticeable than I would like.
Additionally, despite an emphasis on appearance, the XPG SPECTRIX D60G kit has remarkably little in the way of branding. Other than "XPG" at the top of each stick, a small logo on each side, and the specification sticker, the sticks are left bare. This is a great design move as it lets the RGB LEDs that are the draw for this product line do all the talking.
Looks aside, the XPG SPECTRIX D60G performed well in my testing. Despite not having a functional heat spreader, there were no issues with stability in any of my tests. I know the exclusive use of plastic with the LED diffuser will make some people skittish, but the fact is that unless you are pushing high voltages through your memory, additional cooling is not necessary.
For overclocking, the ADATA XPG Spectrix D60G proved to have a decent amount of headroom, reaching 3733 MHz stable with my ASRock Z390 Phantom Gaming 7 and Intel Core i9-9900K combo. That's a good result given the tight 14-15-15-35 XMP timings. My Ryzen testing went even better. The ADATA XPG Spectrix D60G achieved 3866 MHz with the stock XMP timings on my MSI MEG X570 ACE paired with a Ryzen 5 3600X. Manually tuning the timings at 3600 MHz, I was able to tighten the timings beyond their already excellent CL14 spec with no trouble because of the excellent Samsung B-die ICs ADATA has used in the XPG Spectrix D60G.
The final factor is the price. The ADATA XPG Spectrix D60G comes in at US$240.00. Not a cheap kit by current market standards. That doesn't mean this kit isn't worth it to the right buyer. While many will opt for lower specced kits and rely on their own overclocking skills, if you want a great-looking kit with absolutely top-tier Ryzen optimized performance out of the box, the ADATA XPG Spectrix D60G is a solid choice.
