I5 4460 fails to power on with the Z87-G43 motherboard.
I possess numerous CPUs and two mainboards. The key components are the H81l-PLUS, Z87-G43, I5 4460, and Pentium G3220. According to my setup, both CPUs run smoothly on the H81l-PLUS, but only the Pentium launches in the Z87-G43. The boot process works for the Pentium, yet the I5 prevents access to the BIOS. A similar discussion was found online, though it might not apply here since it worked with a different board and RAM. The specs are listed on Intel and ASUS sites, along with the power supply details.
Install the Pentium on your Z87 board and update the BIOS to version 17 or higher. It appears the current release handles Haswell, though not Haswell Refresh.
I attempted using the 1.7 update, but it didn't alter anything → the same behavior remains. → I'm going to revert to the latest release, which I've used before. Edited September 27, 2023 by DeuMoneyMaster
Did you clear the CMOS? I recently installed an older H87 board with a reliable CPU (also a 4460), but it wouldn’t start at all. After taking the battery out for a few minutes and putting it back in, it started. Then I discovered the CPU seemed to have stopped working unexpectedly, so I swapped in another 4460 and it functioned properly now.
I'll attempt it later after school. However, I performed a reset once; perhaps trying again would help since the M.2 fast boot might not work with MSI.
I've checked and it didn't function properly. Do you have more ideas to share?
No, it wasn't a CPU failure there—it was just the evidence that showed otherwise.
Have you considered deleting the GPU? It’s a rare move, but it might cause the system to switch to integrated graphics. I’ve seen this on Haswell boards before.
for that reason I connected VGA onboard and HDMI from the graphics together, but no signal appeared. I did the same on the smaller board and it functioned there. Honestly, I’m running out of ideas—both boards are working individually, but when combined it doesn’t boot up properly. The BIOS isn’t current, and it got reset after an update. Since one of them has an onboard connection plugged in, that should provide a signal. RAM and power supply are identical on both sides; the only difference is the board itself.
Consider removing the GPU. It’s unclear, but your socket might have a bent pin for the i5 that isn’t present for the Pentium. This could be a guess, though the i5 likely uses more pins due to its higher tier.
