So my additional 8GB or RAM finally came in. And after a bit of hassle installing it, the BIOS and Windows show only 8GB of RAM still. Interestingly enough, according to CPU-Z, all 16GB check out.
Now here's the important part:
After an overclocking session a few months back, I had to reset the bios, and for some reason, my multiplier is locked and the HD4000 graphics isn't detected. I'm thinking this is likely a BIOS chip gone bad.
So, would a bad BIOS chip prevent 4 sticks from being detected? If so, where can I get a new BIOS chip cheaply?
I think you have to update your BIOS once. Check for the latest version of BIOS and download. IF the BIOS chip was bad you would not be getting any display. Also make sure that the RAM you are using is supported by your mobo.
