I tested the beta bios 1634, however, I didn't have stability, even when trying to change the impedance to values already tested at the speed of 6200MHz (see in the photo the values that are stable).
with Beta 1634, the system loads, but tests with TM5 show errors within a few seconds. The SoC voltage can be made less high, but the MC voltage has to stay close to 1.400V.
more tests with some changes:
tWR
Rtts (after more tests, we verified instability and it was no longer possible to enter the operating system, when starting from cold. See in the next image)
vSoC
tREFI
tests show that this configuration below has proven to be the most stable so far, the one where we changed some parameters (Rtts) resulted in great instability when we went to cold restart the system, in addition to showing some strange outbreaks in the operating system. When changing these parameters (Rtts), it did not help to increase the vSoC and MC voltage.
Note that we increased the voltage of the memories due to the reduction in tWR.
