I have a Gateway NV79 laptop with a narra2-g8le motherboard. I have replaced my original 3GB memory with 8GB Crucial memory. However, the System function only reports 2.85GB. The bios reports 8GB. Dxdiag also reports 8GB. However, when using the system function it reports 2.85GB. I have run Specyy which shows 3GB installed. Is there a jumper on the motherboard or should the bios be reinstalled to recognize all 8GB. The model number is a6330f.
