Overclocking
Besides the already very tight XMP timings, the kit is of course also overclocked once again in our benchmark race. Today, there are even two different overclocks, once with active cooling for the absolute performance maximum and furthermore with passive cooling for a somewhat more conservative compromise.
In fact, even with manual overclocking, the kit lives up to the expectations one might have when buying the fastest DDR5 kit to date. DDR5-7000 can be stabilized on Asus’ Maximus Z690 Apex from this year and our test CPU with a particularly strong IMC (Integrated Memory Controller).
A few other kits have cracked this mark in past tests, but never together with tCL 30 at 1.55 V VDD and VDDQ. The rest of the timings are also on the same level or tighter than all other Hynix M-Die based DDR5 kits, with the exception of tCWL where so far the G.Skill Trident Z5 kit remains untouched with its 10 layer design.
Also because there is already an even higher clocking successor IC from SK Hynix, which we have also already looked at, I would like to show another streamlined configuration with manual subtimings for the specified 6600 Mbps as an alternative. If you believe the previous Zen4 leaks, overclocking in this range could also be interesting for the upcoming AMD DDR5 platform in 1:1 mode.
The voltage remains at 1.4 V here and tREFI in particular has to be significantly defused in order to still perform refreshes sufficiently frequently even at high temperatures of up to 70 °C. Especially the activate timings and the tertiary timings, which are important for bandwidth, can be optimized significantly compared to XMP.
