Hello!

I have problems getting my new i7 4790k to run on my Z87-A.
When I start the PC it wont boot at all, and the red CPU_LED is not turning off.

I have updated my BIOS to the 1707 version, still doesnt work.
I have tried with 2 different i7's and I had the same issues.
I have tried switching back to my older i5 4670k and it runs just fine.

Thankful for any ideas!
 


That is weird. Ive read on many places that 1707 was enough.
I did update to the very latest driver this time (2103) and the issue is still there. Constant red light, and no boot.
 

we are talking an Asus Z87-A?
it has to be 2004 , specific bios for that cpu only
Trust only asus
 


Well, they are stating this on the link you sent me.

"If your motherboard BIOS version number is greater than the BIOS version listed above, then you will not need to flash your BIOS. However, if your BIOS version is smaller than the version listed above, then you will need to select and download the latest BIOS to update your system. "

Are you sure?
 


unless they state in cpu/bios compatibility list otherwise and asus say 2004 with that cpu, otherwise it would say bios number....... and after. Do what you want man. Obviously Asus and myself are wrong. Did you want an answer or a dispute
 


It states "Validated SINCE BIOS 2004". So dont be like that please. Ive tried so many things, and switched cpu back and forth so many times at this point. I dont want to do it unless it feels like it will fix my issue.
Still thankful for the answers you gave tho :)
 


you think asus would put 2004 bios as the one to run with that cpu for nothing, go to the bios downloads and read the 2004 bios notes...... for support to new devils canyon.....................YOUR CPU. your board has bios flashback, , save the old bios onto usb and use it if 2004 does not work, at least try. those latest bios was made for other cpu's. 4790k has just one specific bios and it's latest of the type, it's beta
 


Well, asus are saying the CPU will work on every update after the 2004 update. Probably to let the people with the 2004 version know that they dont have to update it.

But I will try and get back with answers.
 


You have it wrong obviously because it does not work on latest, does it
your board has bios flashback, , save the old bios onto usb and use it if 2004 does not work, at least try. those latest bios was made for other cpu's. 4790k has just one specific bios and it's latest of the type, it's beta
 


I tried and I still have the exact same issue. The updates are NOT for specific CPUs. They are adding support for CPUs after each update, otherwise my i5 4670k wouldnt have worked on ALL of the updates Ive tried (1707, 2103, 2004). It would only work on update 0801.
 


Yes but having tried 2004 and latest on their compatibly list rules out bios problem, runs well with the other cpu.board makers say yes to that cpu , Well must be dead chip then, surely? Anybody ?
