The V-Color XFinity 8400MT/s memory kit has one XMP profile rated at DDR5-8400 CL40-52-52 and 1.45V VDD/VDDQ. It’s about the best we can get at 1.45V. In our tests, we could lower the CL to 38 and tighten sub-timings a bit, which gave us lower latency. However, it’s still not much better in real-world applications than at the XMP profile. I will return to overclocking on the next pages of this review.
The memory kit is designed for only a few motherboards, such as ASUS APEX/APEX Encore, Gigabyte Tachyon/Tachyon X, or EVGA Dark. Officially, it’s even less, as the QVL is limited to ASUS APEX and Gigabyte Tachyon X. As overclockers know, having a CPU with a powerful memory controller is more important than the top motherboard. I won’t hide that only two of the twenty CPUs we tested could run stable at 8400MT/s.
Because of the above, there is a high chance that the 8200MT/s+ memory kits will not work stable at XMP settings, regardless of how much we pay for the PC.
Like other top-speed DDR5 memory kits, the XFinity 8400MT/s uses Hynix M-die IC and Richtek PMIC, the most popular combo, fully supported by all leading motherboard brands. It’s the best we can find if we search for top-speed, overclocking DDR5 RAM.
Above is a whole timing list that reads ASRock Timing Configurator software at the XMP profile. The profile works fine with the ASUS Z790 APEX motherboard and Gigabyte B650E Master, with Ryzen 7 8700G APU. There is no RAM with EXPO profiles dedicated to AMD motherboards at such high speeds, so buying one for an AMD-based PC is always risky.
So far, so good. Now, let’s take a look at the product itself.
