[R630] Memory module issue
Hello,
I purchase a new ram, 4 modules of 64GB of DDR4 (M386A8K40BM2) for a Dell R630, I remove all of my old memory (12x32GB modules), but now the system detects only one module.
Its a bi-cpu configuration, with e5 2660 v3.
I set the modules in the A1, A2, B1 and B2 slots, but only the A1 is detected. I have no logs or anything about the others modules.
Do you have any ideas of what happen?

Hello thanks for choosing Dell and welcome to our community.
If the memory modules are confirmed to be compatible (it is, in this case, I checked internally) and it's unlikely that three out of four are defective, then the next logical step is to check the memory slots on the motherboard.
Here are a few troubleshooting steps you can consider:
Remove all modules and reinstall them carefully, ensuring they are fully seated in the slots.
Use a single known-good memory module and test it in each slot one by one. This will help identify if a specific slot is faulty.
Sometimes, firmware updates improve memory compatibility or resolve detection issues.
Look for bent pins, dust, or debris in the slots. Clean gently if needed.
