Stock vs overclocking tests:
Of course, this kit will only be tested on an AMD platform, initially, as this kit is intended for this configuration from the outset. We opted for the ROG Crosshair X870E HERO motherboard, which remains the most recent model on this chipset. As we said in the introduction, there will be no comparative tests, as we await the arrival of the ROG Crosshair X870E APEX to update our graphics.
- Motherboard: ROG Crosshair X870E HERO (BIOS 9951)
- Processor: Ryzen 9 9950X3D
- Memory: 32 GB G.SKILL Trident Z5 NEO 6000 MT/s CL26
- Graphics Card: MSI GT 710
- SSD: Western Digital SN850 NVMe SSD M.2
- Power supply: be quiet! Dark Power PRO 12 1500w
- Operating system: Windows 11 64 bits
Our OS is in no way optimised, since it’s the one we use as ‘standard’ for our processor tests.
Overclocking this 6000 MT/s CL26 kit:
For memory overclocking, there are 5 key voltages. These are the voltages that will have an impact on overclocking and therefore on the frequency rise or the tightening of timings. These are the SOC Voltage, the DRAM VVD Voltage, the DRAM VVDQ Voltage, the CPU VDDIO/MC Voltage and the Vddp Voltage. Here’s where you’ll find these voltages in the BIOS of our ROG Crosshair X870E HERO.
Please note that depending on the type of memory chip (Micron, Hynix and Samsung), the balance between these different voltages is different. If your PMIC module is not locked, activating ‘ High DRAM Voltage Mode ‘ will give you access to voltages of up to 2.00 volts. Now it’s time to overclock this G.SKILL DDR5.
By increasing the voltage on the VVD to 1.73 volts and the VVDQ to 1.68 volts, we were able to easily reach a frequency of 8600 MT/s in 32-47-44-48. Of course, we’ve also tightened up all the subtimings . We’re going to carry out an initial series of tests comparing stock performance, i.e. with the 6000 MT/s C26 kit and our overclocked version at 8600 C32. We were also able to push the FCLK frequency to 2167 MHz.
Aida 64 :
This is a piece of software capable of providing you with a great deal of information about your configuration, but above all it has a memory benchmark. This calculates the read, write and copy speeds as well as the latency of your memory kit. It is often used to compare memory kits. It’s an excellent tool if you want to compare the performance of your memory kit with those we’ve already tested. The version used for the tests is 7.60.7300 and we have used the performance of the kits previously tested.
We can see that overclocking is fully beneficial and that throughputs are skyrocketing. Reading speed has risen from 77045 to 102314 MB/s, writing from 80286 to 106030 MB/s and copying from 70935 to 96708 MB/s. Latency, meanwhile, has improved from 77.7 to 66.9 n/s.
Geekbench 3.4.4:
This benchmark is available in several revisions, with version 5 having just been released a few weeks ago. It provides two scores: one single and one multi. Using this benchmark, we’re going to focus on the performance obtained on the ‘ Memory Multi-Core ‘ score, which differentiates memory performance. The version used for testing is 3.4.4.
For the next results, it’s important to bear in mind that the performance gain is only due to memory overclocking. Imagine if you added processor overclocking. The single-core score rises from 9782 to 10506 points (+7.4%) and the multi-core score from 121987 to 125512 points (+2.9%). The memory score rises from 9845 to 13922 points (+41.4%).
Geekbench 5.5.1 :
We’ve decided to add this extra benchmark, but why? The CPU benchmark uses new tests that more faithfully simulate the tasks facing processors in the face of recent applications. Geekbench 5 also increases the memory used during the benchmark to better reflect the impact of this parameter on the CPU results. For the time being, we’ll be keeping both, as version 3 is still widely used. We have also migrated to the latest version, 5.5.1.
The same can be said of Geekbench 5, with the single-core score improving from 2578 to 2686 points (+4.2%) and the multi-core score from 25803 to 28775 points (+11.5%).
Geekbench 6 :
We recently received a key for version 6 of Geekbench. So we took advantage of the change in configuration to add this new benchmark to our test suite. This is the latest benchmark and is intended to be more representative of current configurations. Primate Labs also assures us that the scores displayed by Geekbench 6 are more accurate in relation to the various existing devices and platforms. The test is also much longer than the other two versions we use. Our tests will be carried out on the latest version, i.e. 6.2.2.
Last test and nothing changes, we can measure the gains obtained by our kit of the day clocked at 8600 MT/s in CL36. The single-core score rose from 3482 to 3570 points (+2.5%) and the multi-core score from 22620 to 25959 points (+14.7%).
