MSI X670E Godlike - performance with RAM 128Gb and 3 SSD M.2

[Haereticus]

Good morning, everyone.
A few months ago I switched from an Asus X670E motherboard to the top of the line MSI motherboard, i.e. the Godlike, attracted by some advertised features, including RAM support up to 256Gb, and 2DPC 2R Max speed up to 5400+ MHz (it said 6000+ when I bought the motherboard), and secondly the presence of three M.2 slots totally independent (i.e., unaffected by the presence of other peripherals-at least on paper), specifically slot 2_1, managed by the CPU, running at PCIe 5.0x4 and 2_2 and 2_3 managed by the chipset, running at PCIe 4.0 X4 (the fourth M.2 slot is connected to the third PCIe slot).

I thus transferred my 4 memory slots (128Gb) G.Skill EXPO 6000 and my 3 SSDs (one of which is 5.0) to the new motherboard.

Unfortunately, expectations were disappointed:
with four memory banks it is impossible to boot the motherboard except at the maximum frequency of 4000;

• the performance of the three SSDs is about a third slower than what I was detecting on the Asus MB. To give an example with the 5.0 SSD, which must necessarily be installed in slot 2_1, I get a "score" in the 3DMark Storage Benchmark just above three thousand points, while on the Asus I was well above 4000. With synthetic benchmarks such as CrystalDiskMark I get read/write performance of ca.10,000 versus about 12,000 that the SSD is capable of (SSD temperatures do not seem to be an issue, remaining well below the threshold for Throttling)

Is there by any chance something I'm missing, or more simply are there "limitations" that are not properly advertised in the datasheet?

PS) The only other peripheral present is the GPU, obviously in the first PCIe slot.

Yes, maybe. Even online there is a lot of variability in benchmark performance, depending on who does the testing, and the hardware used. But it seems to me that the result of the random 4K write test, in the case of my disk, is always very low...

Just depends on what review you check.

Anyway, i wouldn't be too concerned about this theoretical benchmark, no real workload ever loads an SSD like that. If anything, the Storage Benchmark is more relevant here. That should be a far more accurate representation of a real-life workload. But yes, it is also highly influenced by the other hardware.

 

[Haereticus]

I agree. In real use I actually don't notice at all that the performance of the SSD seems lower than the results I had with the previous motherboard.
However, I always like to optimise everything where possible.
Apart from this strange case of the SSD, I otherwise don't regret switching to MSI.
On the Asus I had some stability problems, on the MSI so far none. But having also changed CPUs the comparison is not entirely objective.

53°C maximum for the MP700? How does it stay that cool? So it's definitely not anywhere near throttling.

I just realised, reflecting on this point, that the two fans I put on the RAM to cool it, create a good flow of air even above the motherboard heatsink of slot 2_1 (which by the way is the most massive). In fact, the other SSDs (which are also less 'hot') have a temperature that is at least ten degrees higher.
