Ram updated from 4gb to 8gb, it only shows 4gb of ram in system & 8gb of ram in BIOS.

[Kira007]

Product- Notebook 15-g002ax (HP 15 notebook laptop) 64bit

OS- Ubuntu 20.04.2 LTS

Memory shows- 3.3 GiB

amd processor, REV: 22CE-100

New ram added: Hynix HMT41GS6BFR8A-PB, 8192 MB @ 800MHz (SODIMM DDR3)

I used to have 4gb of default ram in bank0 [bank1 is non customer usable]

therefore i have bought 8gb of single ram. removed 4gb of default ram & connected new 8gb ram in bank0.

but if i check in system it only show 3.3gb of ram just like before. And if i check in BIOS it shows 8gb ram.

1. Can i utilize 8 gb of ram on my system ?

2. Should i go back to my old 4gb ram since they both are delivering same ram space?
