Thank for this fast answer
The problem is I have performance issues... cpu seems saturated by pics sometimes, resulting in rollback in game for players.
I think cpu is enough strong to supports, but think the ram is too long.
It's about 14 ark servers.
Here, I saw working 3200mhz with 128gb :
I'm at a point where I am not getting errors anymore (well the errors seem to occur only right before the reboot). Just reboots are occurring after leaving the machine idle for a few hours. I can do 2hr OCCT runs, 3hr zip jobs, 3hr handbrake jobs no problem. Even after thermal cycling the ram...

Ok if I can't reach 3600, but 2900 or 3000 must be possible with stability no ?
Post a Zentimings screenshot and a full-screen HWinfo sensors page screenshot while cinebench R23 is running (at least the 10 minute test, before it ends)
between those, we'll find what's going on
I can do 1.1v SoC for 4x dual ranks but those ain't 32GB dimms. Memory controller most likely just isn't gonna do with that capacity.
I mean, i can run 4xDR at 3200 on these CPU's at the 1.09v default on the new BIOSes as well, but 3600? no chance.
CPU type, ranks, speed - it's a combo of all three, none are important alone.
Some boards are less honest than others, it's as simple as that.
As the most obvious example some asus boards send 0.05v higher than the user sets, just like gigabyte does to DDR4 vDIMM voltage
These values vary between boards, and recently it's been getting attention with BIOS updates where the new defaults are in a lot better ranges for most users (0.95v to 1.09v for vSOC, on my x370 aorus)
Other times it's a rare case where it may be one of the secondary voltages like VDDGIO
On my x570 Asus, 1.15v drops to 1.13v - but note the higher default VDDGIO on this one, as soon as i raise the IF above 1800 (for 3600MT/s on the RAM) it automatically boosts some voltages
Compared to my Aorus B550, which boosts vdimm higher than user set, but doesnt raise vddg IOD or CLDO VDDP at all - shockingly (sarcasm), this board doesnt clock the IF quite as high on automatic voltages (I paired it with single rank memory, so i didn't bother raising them)
This boards set to 1.125v, which reads the same as the asus on 1.15v
This says VDIMM is 1.35v, yet the BIOS and hwinfo show 1.42v - what's set in the BIOS and reported to the CPU, is not what's actually sent
The one thing i cant do is probe the real voltages like the techtubers did with the AM5 scandals, to see how accurate those readings are - the big scandal was that boards were over-volting after the sensors so users weren't aware of it, and thats why CPU's run hotter in some boards, overclock better in some, etc.
(This is why it went wrong so fast - because the boards relied on those sensors to set accurate voltages, so the asus ones made some horrible mistakes if the system crashed - oops no reading, better throw more voltage!)
