Task manager, CPU-z, and HWinfo show the same Memory speed vs Aida 64

As the title states, I am getting different values from Aida vs the other applications

I am using 4 DIMMS. I am aware of the potential for speed issues with all 4 DIMMS populated.

Asus X670e Hero with a 7950x.

Gskill 6000mhz CL30 Expo ram 4DIMMS

I enabled the 6000mhz EXPO I profile through the BIOS. I boot into windows just fine. I disabled core isolation and Hyper-V to ensure no issues with AIDA. I got 71ns for latency.

Which reading is correct? I am inclined to think AIDA is due to the 2 DPC(DIMMs per channel).95571

Both 6000MT/s and 3000MHz are correct, your RAM kit it's operating at a speed of 3000MHz but it's offering you a data transfer rate of 6000MT/s, the NB frequency that you are read there it's the FCLK clock that is syncronized with the RAM to get 1:1 ratio. The AIDA memory clock there it's false I think, probably it's not yet updated for AM5.

I would second this comment about Aida not being updated given its detecting the CPU as a trial version?

When it comes to memory speed specifically, Task Manager, CPU-Z, and HWInfo typically display the memory speed based on the information reported by the system's firmware (BIOS or UEFI). This reported speed may not always reflect the actual operating speed of the memory modules due to various factors like BIOS settings, memory profiles (XMP/DOCP), or system configurations.
