Hola a todos,
Copio y pego el post que he puesto en otros foros, si es necesario lo traduzco, pero creo que se entiende bastante bien, espero que alguien pueda echame un cable:Hallo all,
I just made a build with:
- Intel i9 13900k
- MSI MAG Z790 Tomahawk Wifi DDR5
- Trident Z5 DDR5-7200 16x2 CL34-45-45-115
- Zotac RTX 4070 Ti
Problem:
With the default XMP at 7200 activated, the computer works fine, but as soon as a I play any game, after playing 5-10 minutes, the screen freezes and it crashes kicking me out to the desktop (tried elden ring, dead space and doom eternal)
Things I tried:
- Updating BIOS, Chipset and all other drivers for the MAG Z790
- Changing the ram sticks to different sockets. Before they were in the "First" sockets. Changing them to the "No First" sockets makes that I can not even activate XMP profile. I had to go back to the "First" sockets
- Decreasing the XMP frequency down to 6600. On this way it does not crash anymore, that is why I have figured out the problem is the XMP profile
I have seen a lot of posts with the same issue, but nobody found a solution. Maybe doing some custom XMP profile with tweaks in voltages and latencies could work but I did not have the time to test. It is a shame since the Z790 is supposed to support this 7200 frequency. I saw the last BIOS version is from January, they are making a new update each 2 months up to this point, so I hope a new update is coming soon.
Anybody with similar hardware found a solution to run the ram at "default" 7200?
I can really see the performa impact between 7200 and 6600.
Kind Regards!

UPDATE1:
I have been playing with different parameters on the BIOS trying to make stable the ram at 7000. I have been using Karhu for testing the stability.
Below is the list of parameters I tried to modify one by one, increasing it a bit and checking if the coverage in the Karhu test increases o decreases:
-RAM Frequency: keeping it at 7000
-DRAM VDD and DRAM VDDQ: I found that the more increased this values, the more coverage I got in the test. I tried up to 1.59V for one test.
-CPU VDDQ: increasing it +0.2V was reducing the coverage in the test
-CPU VDD2: tried to increase it manually +0.1V and my computer was not switching on
-VCCSA: the more I increased, the more coverage in the teat I got. I tried up to 1.4V for a test.
-PLL (CORE, RING, SA, MC): increasing or reducing them was drastically reducing the coverage in the test
At the end my best test, with 2066% coverage when it found an error, was using the following parameters (everything else in auto):
-RAM Frequency: 7000
-DRAM VDD and DRAM VDDQ: 1.59V (Ram where peaking to 65 degrees during the test)
-VCCSA: 1.4V
Not even stable at 7000 with super high voltages...
For more info, here is a picture of all the voltages, with the XMP activated at 7200, with all voltages in auto:

I will try to run a test at 6800, modifying only DRAM VDD, DRAM VDDQ and VCCSA (and maybe also decreasing the primary times for decreasing the latency to CL32 or CL30).
Or I had bad luck the the MSI Z790, or the BIOS is a potato and really needs one update.
I will let you know what are the results of the mew test.
Cheers!!
