I have two Asus H series boards, an H87I-Plus and an H81M-C. Each is confirmed compatible with the i5 4590S, 4460S, and 4590 CPUs. All are updated to the latest BIOS. They function perfectly with an i3 4130 or a Celeron G1820. None of these CPUs will boot up on any of the installed i5 models. Despite this, all three CPUs perform well on an HP Pegatron IPM87-MP motherboard—also featuring an H87 chipset? This suggests a potential BIOS-related issue with Asus rather than a hardware problem. I reset the BIOS to defaults during swaps and using the jumper, but nothing changes. Why won’t any of my Asus boards work with these three CPUs? Am I missing something important? Here’s the CPU list from Asus for both boards, in case anyone needs it. I hope this clears up your confusion—this setup seems to be working surprisingly well! If you’re determined, let me know what you find next.
Has anyone tried the Asus H8x board with an i5 45xx/44xx CPU? If yes, let me know what worked for you.
I received an i3 4150 recently and it doesn't fit into either Asus H series boards. This is confusing!? I'm planning to downgrade the H87 BIOS to version 1005, which is the first listed compatible with this model and the 4590. I assumed all updates from that point would work too. Why aren't the latest Haswell refresh CPUs recognized by these boards with the current BIOS? Do they even support the original BIOS? I'm really unsure and will try everything now. It seems possible to keep testing different BIOS versions until I find the right one. I found someone using my exact H87 board with an i5 4590 on PCPartPicker, so it must work with some BIOS version. I created an account and left a comment asking about the BIOS version, but it's been over two years since they posted it, so help seems unlikely. Version 1005 didn't work with my i3 4150; I managed to flash it successfully using the 4130. Everyone is puzzled here. It looks like I might be making a mistake, but I can't see where. I really need assistance. Maybe someone knowledgeable can help? @GabenJr Ok, it seems I finally found the right keywords on Google and discovered... well, I'm stuck now. I should install Windows to attempt the BIOS update via the tool. Great idea. I'll try updating and post more keywords so others can find the solution quickly instead of getting frustrated for months. https://www.reddit.com/r/techsupport/com..._with_h87/
The Windows-based BIOS updater update completed successfully. Why is this an issue for ASUS? It seems inconsistent since the BIOS displays the new revision when flashing through the tool, yet it doesn’t actually apply the changes. I’ll proceed with the H81M-C board next and revise this post accordingly. Looking forward to tag suggestions to help more users find this information.
This setup seems quite unusual... I've noticed some odd behavior with BIOS flashing on other manufacturers' boards before, but ASUS tends to perform well in my experience. It might be that this particular issue is why ASUS encourages using the BIOS Flashback feature during upgrades instead of EZ Flash. There could be a multi-step procedure involved, and it didn't activate during the regular flashes you performed.
That's possible that the Flashback method works correctly, I only have one Z87 board with it (and it's working so I'm not messing with it!!). However for boards with don't support BIOS Flashback like my H81 and H87 this is a weird/serious problem to have. I wonder how many CPU's were RMA'd over this lol. I can now finally update the H81, pop in my 4130 which yes doesn't need a BIOS update but to avoid future upgrade headaches it's getting flashed, then get my aunty her PC back to her so I can get my HP SFF system back from her before her cat pees on it too! (Disgusting story if you ever want to hear it) I swear I run my own IT dept for relatives. Thankfully mostly hardware work, praise Linux for that. Also, appreciate taking you taking the time to reply even after I found my solution. I guess this is 'trivial pursuit' knowledge now that the H8x series and Haswell are so so old and hopefully this isn't still an issue with newer Asus products. Sadly it's really turned me off to them going forward.
Updated my note on 01/25/2021. I was configuring a PFsense system and bought an older Asus H87i-Plus board. It was using a BIOS from 2013 version 0306. It wouldn't start with either the i5-4590 or i5-4590k processors. It worked with the i7-4770 when I used it directly. I tried to update the BIOS through the onboard program without any storage device, just using a USB with the file. The update completed as expected but the system still wouldn't boot. After checking online solutions, I decided to proceed with a Windows update. I reinserted the i7 CPU, added a fan to speed it up, connected a drive running Windows 7, and restarted. I then reached out to Asus support. It turned out they needed specific files for the update. I selected the correct version but had to switch to an older Windows 7 64-bit edition first. Once that was done, everything functioned properly. The necessary files are listed below: BIOS Flash Utility (version 2.00.02, 2014), BIOS ver 2003 (last updated 2015-03-25), and the Management Engine Interface V9.0.1287 for Windows 7/8. The utility didn’t warn about the required management interface. I used the version I already had from Asus, which fixed any issues introduced by their previous update tool. After rebooting, the PC started correctly. For your reference, the latest BIOS files are available as H87I-PLUS-SI-2003.zip and the updated installer is listed below:

Thanks for the help! This really made a difference. I need to highlight the Intel Management Engine for anyone else facing issues. It only worked with V9.0.0.1287, but it can be installed on later Windows versions like Win 10. Both Andy G and Bitter are welcome!
Thanks for bringing this up! It really helped me stay calm, and I just wanted to express my gratitude. Confirming that updating the BIOS for the 4th generation 4460 can't be done without using the Windows update tool is correct. Great job, Asus! It’s confusing why this isn’t highlighted on the support pages since it seems the update was already applied. Webstaff.
