CPU / Motherboard conflict?

I am trying to get an i5-4590 to work in an Asus H81M-E motherboard.  Out of the box the MB BIOS version was 0701.

According to ASUS the MB needs, at least, BIOS 0808 to work:

http://support.asus.com/cpusupport/detail.aspx?SLanguage=en&p=1&m=H81M-E&cpu=Core%20i5-4590%20(3.3Ghz,%204C,%20L3:6M,%20HD%20Graphic,%2084W,%20rev.C0)&pcb=ALL&sincebios=0808&memo=*Before%20using%20the%20new%20Intel%204th%20Gen%20Core%20processors,%20we%20suggest%20that%20you%20first%20download%20the%20BIOS%20updater%20for%20new%20Intel%204th%20Gen%20Core%20Processors%20and%20then%20update%20the%20BIOS%20using%20this%20tool.

I flashed the BIOS to 0808 using an i3 I have laying around.  Note that this also means that the "system" (MB, PS, CPU and RAM) worked with the i3 installed.

Putting the i5 back in place yields no results... no beep codes... no nothing.  I can get beep codes putting the i3 on the MB and removing the RAM.

I downloaded and flashed the latest BIOS... 2105.  Same results.

I bought these components in an effort to build two similar units... thus I have two MB and two i5's.  Neither works... I tried swapping components to rule out a bad MB or CPU.

Any thoughts?  It sounds like the i5-4590 just is not compatible with the H81M-E MB.

Are you able to test the i5's in another machine?  Asus' site clearly lists them as compatible with the BIOS update you've already done.

Tried both i5's on both boards. I don't have any other boards lieing around to test with.

I still find it unusual, but I'm starting to think both cpu's got pooched, in transit.   : /
You should be getting "something", if they had any kind of life in them.

Control application downtime with dependency maps

Visualize the interdependencies between application components better with Applications Manager's automated application discovery and dependency mapping feature. Resolve performance issues faster by quickly isolating problematic components.

I went back to the vendor and swapped out both boards... the computers are now built and working.
