Review : Gigabyte Z790 Aorus Elite AX

Memory overclocking:

We now move on to the most interesting part of this test, namely memory overclocking. We expect a lot from this motherboard, whose hardware could suggest good memory performances.

Let’s get to the heart of the matter, all the memory tests were carried out with a Pcore CPU frequency of 5500MHz, Ecore at 4500MHz and a cache at 5000Mhz.

Test on DDR5 Hynix M-die :

We start the memory overclocking tour with a Corsair Vengeance 6200C36 kit equipped with Hynix M-die chips. The latter was tested some time ago on the excellent Evga Z690 Dark Kingpin coupled with a very good i9 12900KS. Here, we will see that the Elite AX has nothing to envy to a motherboard at more than 1 000 € for use with a Hynix M-die kit. Indeed, Gigabyte seems to have done a very good job on these chips and the latest Intel Raptor Lake CPUs do more than well with them.

XMP and bios optimizations

We start with the tests on Aida64 and Geekbench 3 with the XMP vice memory. Here the performance reflects perfectly what we expect from the kit used.

We then move on to the optimizations of the Bios on the memory, namely the low latency mode and the high bandwith mode. As we can see, these options playing on the memory profile as a whole allow a simple overclocking for all. The gain is about 1600 points on the memory score of Geekbench 3. For Aida64, we gain in 5ns in latency and up to 10gb/s in copy and write. A very interesting option for gamers.

Maximum overclocking

We then pushed the overclocking to its maximum (can we push more?). With 7466C32 we reach the maximum obtained on the Z690 Dark and the 12900KS. The gain is about 2200 points on the CPU score and almost 400 points on the memory score on Geekbench 3. On AIDA64 we reach 113 Gb/S and 51 ns latency, which is excellent.

Test on DDR5 Hynix A-die:

We continue the memory overclocking with a Gskill Trident Z5 RGB 6800C34 Kit equipped with Hynix Adie chips. The latter had also been tested on a Z790 Apex and an i9-13900K. We will see here, this Aorus Elite AX also does very well.

XMP and bios optimizations

We start with the tests on Aida64 and Geekbench 3 with the XMP vice memory. Here the performance reflects perfectly what we expect from the kit used.

We then move on to the optimizations of the Bios on the memory, namely the low latency mode and the high bandwith mode. As we can see, these options playing on the memory profile as a whole allow a simple overclocking for all. The gain is about 2000 points on the memory score of Geekbench 3. For Aida64, we gain in 5ns in latency and up to 10gb/s in copy and write. The gain figures are almost identical to the use of an M-die kit. The gap is widened by the higher base frequency which does not change after the optimization.

Maximum overclocking

Just like the M-die kit, we pushed the overclocking to its maximum with this time 8000C34. The gain is about 2200 points on the CPU score and more than 4000 points on the memory score on Geekbench 3. On AIDA64, we reach 120 Gb/S and we pass under the 50 ns latency, which is excellent. We are slightly ahead of the M-die kit in terms of performance but the time spent is much more important. We feel we are at the limits of the motherboard in A-die while in M-die a margin of progress still seems possible.
