The XPOWER Zenith C40 32GB DDR5-5600 memory kit from Silicon Power has impressed us positively in terms of overclocking capabilities, being able to operate it error free up to 6400MHz, by only raising the operating voltage to 1.3V! The modules did not overheat, barely got warm thanks to the included heatspreaders, while the RGB lighting can really light up the inside of your computer case!
CPU: Intel i7-13700K @ Stock
CPU Cooler: be quiet! Silent Loop 2 360mm AIO

SSD: Silicon Power US70 1TB PCIe 4.0
Case: Cooler Master ATCS 840
The pre-programmed timings and frequencies can be also found by using AIDA64; the DRAM IC manufacturer is listed as SK Hynix:
There is a single XMP profile loaded, with no EXPO support.
We did first start testing this kit on our trusty Z690 CLASSIFIED from EVGA and the stability at stock speeds and had no stability issues.
Overclocking stage was next, which implied raising the frequency to 5800MHz, while leaving the stock CAS latencies. The system has proven itself very stable without raising the voltage!
Next, we ran at 6000MHz, also with the same timings and sub-timings and we were impressed by full system stability at 1.25V!
Judging the current results, we went ahead and raised the frequency to 6200MHz and obtained full stability at 1.3V:
We were quite impressed that 6400MHz was doable at the exact same voltage:
When we tried 6600MHz, we started encountering errors in TM5, so we stopped here:
