R6EO and BIOS 3006 memory speed falling

[Corna]

The BIOS of R6EO was recently updated to version 3006, but memory speeds have dropped considerably compared to version 0802, all the Settings are the same, with the exception of memory voltage, frequency, timing (18-22-22-42) and tRFC, memory second and third timing are auto, I don't know what to do now to get the same performance as the 0802 version, 3006BIOS will have an impact on 9th Gen CPU, but not on 7th Gen CPU. the BIOS 3006(the official default microcode 60), Modded microcode 49 and 69 have all been tried, with the same performance degradation, why ? is there anyone else who has the same problem as me ?
R6EO + 9980XE 4.5G + DDR4 3800, I use Tistou77's Modded BIOS

You have changed the DRAM / FSB ratio ?

You have changed the DRAM / FSB ratio ?

BIOS 0802 - 3733 18-23-23-43
BIOS 3006 - 3800 18-22-22-42

All other Settings remain the same

The ram frequency has changed
I have no difference with the 3006 (same frequency/timings) and the R6E

Maybe tested with same frequence/timing, to see

I've updated them both with the same frequency and timing

[tistou77]

compare secondary and tertiary timings between the 2 bios
The changes should be there

I use the profile, so no difference

This is the result of comparing the second and third time series of the two, and changing them to the same value as the 0802 version. The difference is still a bit too big

Number show may look more different however in real working it was a little bit.

Let trying CPU Z Benchmark or Anything prove that.*

Those captures don't show secondary/tertiary timings. U can have the same primaries but looser secondaries/tertiaries and see a great decrease in performance. For example with a lower refresh interval, the Aida bandwidth is quite lower. Your captures of Cinebench and CPU-Z neither show clocks during the tests.

U should open Asus Memtweakit and hwinfo64 apps during the tests and then take an image showing all the info ir order to have more details.

In my case, Omega and 7980xe as CPU, 3006 provides similar results in Aida64 as 0802 using the same timings at 3800/4000, same for CPU-Z or Cinebench when clocking the CPU at 4.8GHz. Memory stability is even better in the new 3006.
