DDR5-7200 XMP Plug and Play*
In terms of RAM OC and compatibility, the Godlike lives up to what it says on the QVL, but with a small catch. Here you can see the fastest kit from the board’s QVL list, from Corsair with 7200 Mbps XMP profile, in stable operation and all without further tuning of the voltages. The automatically set subtimings are quite lax, as is typical for XMP, but especially the activate timings tRRD_s, tRRD_l and tFAW are a good bit tighter than in MSI’s Z690 boards. The automatic values of the voltages with 1.3 V SA, 1.4 V VDD2 and 1.5 V CPU VDDQ are again XMP-typically set relatively high, but from my experience not dangerous for the CPU.
Exactly here the catch comes into play, because not all CPUs “like” e.g. such high values for CPU VDDQ and even partly refuse to start completely with it (Qcode 26/28). Here, a manual lowering to 1.4 V can help. However, other CPUs need higher voltages and a few CPUs are not even capable of running such high RAM clock rates stably. Keyword: Silicon Lottery. MSI is also caught between two stools here and can only offer a compromise solution that works in most cases. There will certainly (have to) be a separate article about the whole topic of DDR5, XMP and QVLs with Z790.
Resourceful readers will already have noticed in the screenshots that more than 1.435 V VDD/VDDQ are used, although Hynix OEM DDR5 modules with a locked PMIC are used. This works because MSI has also integrated the “Special PMIC Unlock” from the Z690 overclocking motherboards here.
Fully equipped with DDR5-6400
The compatibility with 4 DDR5 modules should also be interesting for many users of such an all-rounder board. As an example, 4 single-rank Hynix A-Die JEDEC modules with 16 GB each are installed and stably overclocked to their maximum. The workstation clientele would probably also still have up to 4x 32 GB modules installed, but this would effectively mean quad-rank and thus make the sense and possibility of any overclocking obsolete.
DDR5-6400 doesn’t sound impressive now, but you also have to consider that many users of the first DDR5 CPU generation already often struggled with 5600 Mbps upwards in such configurations. Then to crack the multi-core memory score of 14000 in Geekbench 3 with a relatively low clock is even more impressive. Unfortunately, I cannot provide a complete stability test at this point due to lack of time, but this configuration should not be far from daily usability.
I also briefly tested Hynix M-Die modules and at least DDR5-6800 can also be booted without problems with 2 single-rank modules. So, the Z790 Godlike delivers what the QVL promises in terms of RAM as well, albeit with caveats and dependence on the CPU in the fastest new A-Die kits beyond 7000 Mbps in XMP.
However, while I’m writing this article, MSI has already released another new BIOS, which is supposed to deliver better RAM performance. In this respect, the already good compatibility should only get better in the near future.
