Overclocking on our Z690 APEX:

Choosing your DDR5 kit based on memory chips :

As was already the case with DDR4, if you want to clock your memory, some brands will have a better potential. Currently, the kits announced by the various brands benefit from either Micron, Hynix or Samsung chips. The latter two brands will be the most interesting. Our Teamgroup Delta 6400 MT/S CL40 kit is of course equipped with Hynix chips.

The “key” voltages of DDR5:

For memory overclocking, there are 4 key voltages. These are the voltages that will have an impact on the overclocking and therefore on the frequency rise or the tightening of the timings. These are the CPU System Agent Voltage (SA), DRAM VVD Voltage, DRAM VVDQ Voltage, Memory Controller Voltage and IVR Transmitter VVDQ Voltage. Here is where these voltages are located in the BIOS of our ROG Maximus Z690 APEX.

Beware, depending on the type of memory chips (Micron, Hynix and Samsung), the balance between these different voltages is different. Don’t panic, we’ll come back to this in detail in our guide on overclocking Alder Lake and DDR5. If your PMIC module is not locked, enabling ” High DRAM Voltage Mode ” will give you access to voltages up to 2 volts. Let’s go for overclocking this DDR5 from Teamgroup.

Step 1: The profiles of our APEX 6200 MT/s 36-35-35-52 1T

The first step is to go to the BIOS of our ROG Maximus Z690 APEX and more specifically to the timings section where profiles are waiting for us for the three current chip types: Micron, Samsung and Hynix. Here, as you will have understood, we will opt for the highest profile for Hynix, namely the 6200 MT/s at 1.435 volts with timings of 36-35-35-52 1T. This profile launches without any difficulty and is perfectly stable to pass our three benchmarks: AIDA64, Geekbench 3 and Geekbench 5.

Step 2: personal profile 6400 MT/s 30-37-37-51 2T

This first profile is based on the screens that I could see on the internet and the information that I could collect during the last days. It is also important to know that thanks to the ROG team and Shamino in particular, we received several BIOS patches in a few hours. We also used version 0053 for our tests.

Step 3: best personal profile 6600 MT/s 30-38-38-52 2T

Thanks to Safedisk’s advice, I set out to build my own profile since it was impossible to boot from the BIOS at 6600 MT/s. I was able to optimise a 6600 MT/s profile with timings of 30-38-38-50. Please note that the impact of subtimings is also very important. In order to push the whole thing to the maximum, I opted for 5300 MHz on all the P cores and I was even able to raise the BCLK to 101 or 101.5 MHz to reach 6666 MT/s Geekbench 3 and 6700 MT/s AIDA64.

I hope to improve these scores in the coming days by continuing to optimize the subtimings.

Overclocking performance summary :

Here are our updated test charts so you can see the gains from overclocking in the different benchmarks we use. We’ve added the benchmark scores as well as those obtained with the three profiles above. Let’s start with AIDA64 to see the impact of overclocking our kit on throughput.

As you can see, the basic performance was already excellent and our different profiles still allow us to significantly improve our scores. Under AIDA64 in reading, we exceeded 106K. But it is especially the “writing” and “copying” scores that are exploding! Let’s go to Geekbench 3 to observe the memory performance score which is often the one that climbs the most. And it is indeed the case, since for the first time, we managed to exceed 13K.

Finally, let’s finish with Geekbench 5 in version 5.2.5. The same observation, even if it is less obvious on our two graphs, the scores are still improving even if here, the GSKill kit and its Samsung chips compete much better.

Now that our various tests are over, it’s time to conclude.
