A Closer Look

The XPG SPECTRIX D50 ROG CERTIFIED RGB DIMM modules are using reflective coating on an aluminium base.


Laying down the memory, we can see the XPG logo across the middle.


In partnership with ASUS, ADATA created this XPG ROG Certified memory. As such, one side has the XPG brand logo and the other ASUS ROG branding.


On one side of each DIMM module is the identification sticker listing the SKU, rated XMP operating frequency, and CAS value. This XPG set is a good example of what should be listed. It has it all, even the XMP profile operating voltage.


The XPG SPECTRIX D50 ROG CERTIFIED RGB weighs in at 75 g on my scale. For Z-height, it is 43 mm rounding down with my calipers. These are a bit high for height-constricted setups. If an air-cooler is being used, it is best to consult the documents to make sure it will be compatible.


After taking the heatspreader off, we see a single-sided DIMM with eight 1 GB ICs. The thermal tape is placed across the entire length, allowing it to hold firm and provide cooling to the ICs. Operating at 1.35 V, it is not necessary to have a heatspreader in high-airflow cases. However, if you plan to overclock, extra thermal dissipation is always welcome.


Removing the heatspreader reveals these ICs are SK Hynix DJR. If Samsung B-Die is not available, the currently next-best low-latency option on the market is the SK Hynix DJR used in this kit. The nice thing about the DJR revision is that it can handle a high amount of voltage when it comes time to overclock if you have the means to keep the ICs cool enough. However, be warned that there is always a risk associated with overclocking, and it will void any sort of warranty.

Thaiphoon Burner Readout

Thaiphoon Burner is a helpful program and reports the SPD information in detail. Everything is reported correctly, and this kit also has a second XMP profile of 3200 MT/s as a fallback for systems that may have issues with the higher frequency. If no XMP is enabled, the next-highest profile is the JEDEC SPD of 2666 MT/s, which is suboptimal.
