Overclocking
Disclaimer: Overclocking is never guaranteed, so that the results may vary depending on certain conditions and hardware configurations. I am not recommending overclocking if you do not know what you are doing. High voltages may damage hardware, and the warranty will not cover it.
KLEVV is a gaming brand of Hynix, so no wonder we will see Hynix IC under the heat sinks. Hynix M-die, which was used for the tested memory kit, is the most popular in higher memory kits of the competitive brands. The faster A-die is entering the market, but most memory kits rated at 6000-6800MT/s will still use the M-die.
Our memory kit could easily reach the maximum frequency on the new AMD platform, which is DDR5-6400. From this point, we tightened the timings and the lowest possible was CL30-39-39, and lower sub-timings made most of the work in the latency improvements. The mentioned setting required 1.45VDD/VDDQ voltages, so still not very high but about maximum for long work without additional airflow. The memory kit was not showing any stability issues up to 67°C. Most Hynix-M-based memory kits are starting to lose stability above 60°C, depending on the frequency.
The lowest CL possible to set was CL28 at 6000/6200MT/s and CL30 at 6400MT/s. Some previously tested Hynix M-die-based kits could go down to CL26, but on other motherboards, so this can be the limiting factor. CL28 or CL30 is still exceptional for the memory kit that is rated at CL40.
With the scaling we see, we can expect the KLEVV memory reaches even DDR5-7000 on the latest Intel motherboards. Since we don’t have such a setup right now, then we will try to update our results once it appears in our redaction.
I’m sure that anyone who decides to get the KLEVV CRAS XR5 memory will have a lot of fun overclocking it.
