Only 10GB appears during the 12GB RAM installation process.
I received my old i7 for my nephew. It has 8GB of 2x4GB RAM installed. The motherboard is an ASUS P8P67, and the first version I got had some used working RAM that matched the speed, voltage, and size. If I add one 4GB stick, it reaches 12GB total. The BIOS only shows 10GB. When I add another 4GB stick to make it 16GB, the PC turns on but doesn’t boot. There are no beeps when testing each RAM slot, so everything seems fine. I searched for a BIOS update and found one here: https://www.asus.com/nz/Motherboards/P8P...Desk_BIOS/. There’s an update titled “Improve memory compatibility.” I downloaded the latest version, copied it to a USB stick, and used BIOS EZ Flash. I selected the file and followed the instructions. If I recall correctly, it says the BIOS file failed an integrity check. I’m wondering if I have the wrong BIOS file because I still have the original box, which came in its standard packaging—not a deluxe version like Rev 3.1. What should I do next?
Consider updating the memory controller or replacing the CPU and cooler.
I understand it might seem odd, but using a USB utility like Rufus to erase the drive again and attempt a BIOS update is a valid approach. What BIOS version are you currently using on the board? Some systems require updating the BIOS in stages before installing the latest version, whereas others might start from a newer release like BIOS 3602 instead of beginning with BIOS 0804.
I’d start from 1305 and move to 1401, then jump to 2103 because it highlights “improves memory compatibility” and “system stability.” The last bios referencing that improvement are in 3207. If you keep going, the next likely step would be 3207, which is the one mentioning the improvement. It’d be the best bet if you’re still willing to wait.
