TeamGroup T-Force XCalibur RGB DDR4-4000 16GB Memory Kit Review


Disclaimer: Overclocking is never guaranteed, so the results may vary depending on certain conditions and various hardware configurations. I am not recommending overclocking if you do not know what are you doing. High voltages may damage hardware and it will not be covered by warranty.

We managed to overclock the memory modules to DDR4-4266 @ 1.45V. I just bumped up the speed and increased the DRAM voltage. Simple!




Verdict and Conclusion

These memory modules are a bunch of only a few, that could run at DDR4-4000 straight out of the box. Insert them in to the DIMM slots of a compatible motherboard, go to the BIOS, and just select/enable XMP and that’s it!

The overall performance of the TeamGroup T-Force XCalibur RGB DDR4-4000 memory kits were very good indeed. I got some insane scores during our AIDA 64 memory benchmark.

People always ask me whether faster memory speeds matter, or rather … does it improve performance? Well, the simple answer is yes. If you have a high-end enthusiast motherboard that supports higher memory speeds and XMP, and you pair it with DDR4-3200 ram or above … you will see some sort of performance increase. 

For overclocking, they weren’t too bad. I was able to take them up to DDR4-4266 with a simple voltage increase. All settings were left on AUTO. 

The unique totem designs is really nice, while the ultra-wide 120° angle RGB lighting can make any system look great. It’s compatible with all major synchronization standards, which includes T-FORCE BLITZ (beta version), ASUS Aura Sync, GIGABYTE’s RGB Fusion, MSI’s Mystic Light Sync and  ASRock’s Polychrome Sync. 

There is only one thing TeamGroup could have improved on … and that’s the memory timings, which currently at 18-20-20-44. 

You can  buy the TeamGroup T-Force XCalibur RGB DDR4-4000 16GB Memory Kit for USD $229.99 from Amazon – which I think is acceptable at this current time.



  • DDR4-4000 spec
  • Can be overclocked even further
  • Good performance
  • RGB Lighting Sync
  • Totem pole design


  • Memory timings could be better


Final Words

These memory kits are a good alternative to more popular brands such as Corsair, Kingston, Crucial and Adata. If you want memory kits that offer DDR4-4000 speeds, XMP support, a unique design, and compatibility with all major RGB synchronization standards … then take a look the T-Force XCalibur RGB DDR4-4000 16GB Memory Kits from TeamGroup.
