Help me understand (GPU)

[Darkscapeop]

Hello, so after I got recommended to change my broken GPU( https://linustechtips.com/main/topic/1092683-somethings-wrong-with-gpu-really-need-help/ ), I went to the store and asked for warranty. After 3 weeks of them holding my RTX 2080, they decided to change it and give me a new one. They didn't give a box or anything, just handled me a card. I went home, reinstalled all Nvidia drivers and when I look in Speccy it says 4095MB, when it was originally 8GB card (Some screenshots below). I have 2 monitors connected and it just might be 4095MB each, but I would like to make sure, because I don't know how it works. Thanks.
Full GPU name: ASUS Turbo GeForce RTX™ 2080 8GB GDDR6

Speccy reads half of VRAM for quite a long time now and no one bothered to fix it. It even calls the i9 as Kaby Lake.

Yep, seems like it was just Speccy all along. Appreciate the help.

It appears for whatever reason, Speccy can only count up to 4GB (which conveniently is the maximum a 32-bit number can count), then it rolls over. Evidence to support this are that cards with VRAM in multiples of 4 always show up as 4GB, 6GB cards like the GTX 1060 and the 980 Ti show up as 2GB cards, and 11GB cards like the 1080 Ti show up as 3GB cards.
