RAM detection issue

I installed Kali 2024 on an old laptop with 2x2GB RAM, I then added a “new” 4GB memory bank, so the laptop has 2GB+4GB of RAM.
Here is what the command lshw | grep -A 8 bank shows:


*-bank:0
             description: SODIMM DDR3 Synchronous Unbuffered (Unregistered) 1066 MHz (0.9 ns)
             product: M471B5173DB0-YK0
             vendor: Samsung
             physical id: 0
             serial: D17C5EF9
             slot: Bottom-Slot 1(top)
             size: 4GiB
             width: 64 bits

        *-bank:1
             description: SODIMM DDR3 Synchronous Unbuffered (Unregistered) 1066 MHz (0.9 ns)
             product: AM1U16BC2P1-B1AH
             vendor: A-DATA Technology
             physical id: 1
             serial: 00001C1F
             slot: Bottom-Slot 2(under)
             size: 2GiB
             width: 64 bits

It seems to be ok, BUT

here is what the htop command shows instead:

htop
htop804×141 13.4 KB

Only 1.53G RAM? What is the matter with it? What amount of RAM does KALI actually recognize and use?

Thanks

FIXED!

I swapped the modules in the slots, and they are now seen by htop as well.
Thanks anyway
