Before starting I will quickly detail the PC configuration:
- Motherboard: Asus TUF Gaming B650-PLUS
- Processor: Ryzen 9 7900
- Graphics card: Asus Tuf Gaming RT 7900 XTX OC Edition 24gb
- Power supply: Corsair 1000W
- RAM: G.SKILL F5-6000J3636F16GX2-FX5 2x16 (listed on the Asus website in the list of RAMs supported by the B650-PLUS)
- Bios updated: version 1654
The problem I encounter is the following:
- when I add the second memory stick, the PC boots but the DRAM q-led lights up and the screen does not light up.
I add that the bios was set to EXPO I for testing and that changed nothing.
The problem does not arise with a single memory stick, the PC starts and the screen turns on.
Last point: the strip is placed on A2 and when adding the second, it is placed on slot B2.
Thanks for your help.
Continuation and end :
After testing each memory stick on slot B2, the boot was carried out normally and I arrived on my Windows startup screen.
I made one last attempt with slots A2 and B2. But the Q-led still lit up (orange color) and the boot did not take place.
I therefore decided to ignore the manual and install the two sticks on A1 and B2 and there, miraculously, the boot took place and the startup screen appeared.
I started in expo mode and there too no problem.
I will finish the test today with two other additional memory sticks of the same frequency and brand and I will finalize the report here.
Thank you for the details and for providing information on installing memory in the motherboard slots.
If necessary, please try clearing the CMOS after updating the BIOS or before making hardware changes (such as replacing memory modules).
Please continue to use and observe if there are any other abnormalities.
In BIOS, reduce memory speed to 4800 with two sticks installed in A2 B2.
After if can boot, gradually increase to 5200 and 5600. Test memory stability in Windows (or in BIOS if Memtest86 is available in BIOS) - using any free software, Testmem5 or Memtest86.
Finally, after getting the memory to work, condider updating to the latest BIOS - reportedly the latest AGESA greatly improved the memory training for AMD.
