Overclocking
Disclaimer: Overclocking is never guaranteed, so that the results may vary depending on certain conditions and various 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.
Zenith DDR5 series uses Hynix IC, which is great news for all those who love overclocking. Right now, it’s the best IC if we wish to reach high frequencies and low latencies.
On our AMD Ryzen platform, we were able to reach DDR5-6400 or go as low as to CL26 at DDR5-6000. Both results perform similarly in most tests, while DDR5-6400 is easier to stabilize and requires a lower voltage. The DDR5-6000 CL26 required slightly above 1.50V, while the voltage for DDR5-6400 CL30 was 1.45V. Voltages up to about 1.45V are typically easy to stabilize. 1.50V is already quite hard without additional cooling. On our test rig, the AIO cooler and M.2 heatsink were doing an additional job, and all was surprisingly stable without an additional, direct fan. However, you can expect memory errors at this voltage, higher frequencies, and temperatures above 60°C.
AIDA64 is in the beta version, which isn’t optimized for the latest AMD processors, so readings are not fully correct. You can also expect lower latency on a freshly installed OS and the best in Windows 10. Windows 11 is slightly slower, and background services are causing higher latency.
Either way, our results are great and much better than expected. Since current AMD motherboards are limited to DDR5-6400 (cherry-picked CPUs may work up to DDR5-6600), then we couldn’t make more. The scaling suggests that the Zenith DDR5-5600 kit can even pass DDR5-7000 as other memory kits with the same IC, but on Intel motherboards, could make much more.
The overclocking headroom of the Zenith DDR5-5600 kit is amazing. Again, I wonder why Silicon Power stops at so conservative XMP profiles when their RAM can clearly make much more without issues.
