As far as I know, RAM only comes in GiB sizes. There is some overhead that reduces the amount you see in the OS though. But that complaint is valid for storage devices if you don’t know the units and expect TB/GB on the box to match the numbers in Windows
Your RAM is in GiB and GB. You can measure it either way you prefer. If you prefer big numbers, you can say you have 137,438,953,472 bits of RAM
Pretty sure the commenter above meant that the their RAM was advertised as X GiB but they only got X GB, substitute X with 4/8/16/your amount
