CPU remains inactive despite BIOS compatibility.
CPU remains inactive despite BIOS compatibility.
Hey there! I'm facing the same issue with my ASUS Z270P Prime board. The latest BIOS should support an i5 6500, but it doesn't recognize it when the CPU is installed. It works with my G4400, though. After resetting the BIOS by removing the battery, I've tried various i5 6500 and i7 6700K models without success. I've also experimented with different RAM sticks, PSUs, and GPUs, but the problem persists. I attempted to flash an older BIOS version, but the motherboard refuses it. Anyone have any ideas or solutions? (:
I'm curious about whether the latest BIOS versions remove support for the 6000 series chips. I plan to install the 0207 BIOS and check compatibility with the 6500. Don't forget to reset the CMOS after flashing and when swapping processors.
My motherboard is also on version 1205 but I bought 5 of these boards from a guy that was planning on mining with them so maybe he hacked the bios? Resetetting it didnt help tho. I also doubt that it is the igpu because my mouse and keyboard also dont light up. I bought my i7 6700k and the two i5 6500 from the same guy so there is a small chance that I got scammed and that they dont work but I have no way of testing that. I also bought 5 ssds from the same guy and they work fine..
Unfortunately, when I attempt to flash an older BIOS using ezflash 3 I receive a 'this is not a proper bios' message, preventing me from choosing it. I’m pretty sure it’s a valid BIOS file, since the same one worked on another USB drive (1205) at the same time.
Do you have five of these that aren't functioning or is it just one? Were the 1205 bios included or was it someone else? If the person who flashed it is responsible, the issue might not be the genuine 1205. Are there any error codes? Are there LEDs on the motherboard side that display errors? It seems to work with the G4400 but not with the 6000 series chips. If only one motherboard is affected, inspect the pins in its socket. Perhaps the i5/i7 models use different pins than the G4400. Based on experience, a misaligned pin can easily stop the CPU from booting.
He didn’t update the BIOS on the motherboard, only changed the BIOS settings but didn’t flash a new one. The board lacks debug LEDs, making it hard to verify changes. It’s possible he altered the BIOS settings so it only recognizes the G4400 chip.
I don't understand mining much. I think they might have reduced the voltage for the CPU to improve efficiency, but the i5/i7 tend to draw more power. It seems to work with the G4400 but not with i5/i7. Have you checked for updates beyond versions 1205 and 0207? Maybe try updating to 1010, which could be after the Intel microcode update. Also, see if you can update the BIOS using Windows tools (EZUpdate) or directly in the BIOS (EZFlash). If the update is blocked in the BIOS, it might run on Windows. I'm just sharing some troubleshooting ideas to help. It's really confusing right now.
Recover the BIOS and set up the original ASUS board by placing the motherboard disk into the DVD reader and starting the process. Choose the BIOS recovery option and continue to flash the settings. Make sure to disconnect the hard drives beforehand to avoid conflicts with the boot sequence. Success is guaranteed.
