MOBO not recognising CPU

Posted (edited)

Hey all

 

Wondering if anyone might have any advice

I've gone out and got a new motherboard to fit some more RAM. I went out and purchased a mid range MSI Z-390-A PRO. After some pretty heavy trouble shooting, First one didn't want to seem to work so I swapped it on the same day

 

I've now hooked up the second one and I'm getting a different issue to the first. The Ez debug LED is showing that it isn't recognising the CPU

 

I've trouble shot this one as well and just ran it bare bones. Still same result. I've gone as far as putting everything back into my old motherboard with no issues what so ever. 

 

I've reseated EVERYTHING...TWICE! Including the CPU

 

Has anyone gone through this before or have any suggestions before I take this one back as well? 

 

EDIT: Thanks to everyone for helping! CPU wasnt compatible. Problem has been corrected :) 

 

Thankyou in advance for your help15869442772455503046861254654642.thumb.jpg.03e94da20c3954fb65dd46fa81fcc654.jpg

z390 = 8th/9th gen cpus intel. 9900ks needs a bios update to the board, or else it will not work until you update the bios with a 9900k or lower. 

 

im using an asrock z390 board, but 8086k. read on bios update webiste about this, not sure for msi.

main rig:

CPU: 8086k @ 4.00ghz-4.3 boost

PSU: 750 watt psu gold (Corsair rm750)

gpu:axle p106-100 6gbz msi p104-100 @ 1887+150mhz oc gpu clock, 10,012 memory clock*2(sli?) on prime w coffee lake igpu

Mobo: Z390 taichi ultimate

Ram: 2x8gb corsair vengence lpx @3000mhz speed

what processor are you using?

6000 and 7000 series are not compatible with z370 and z390 ( and all 300 series boards)

8000 and 9000 series are compatible with z390 but the i9 9900ks needs a bios update

Main PC [The Rig of Theseus]:

Secondary PC [Why did I bother]:

PSA: No, I didn't waste all that money on computers, (except the main one) my server cost $40, the intel NUC was my old PC (although then it had 8GB of ram, I gave the bigger stick of ram to a person who really needed it), my laptop is used and the second PC is really cheap.

I like tinkering with computers and have a personal hatred towards phones and everything they represent (I daily drive an iPhone 7, or a 6, depends on which one works that day)

yes but I don't think he is using a 9900ks on that board

I feel like everyone here is sitting ready to post "that CPU is not compatible with the motherboard" once OP comes back and tells us he is using like a 6th or 7th gen CPU in that motherboard.

Something in me tells me this is not a 9900KS, with that stock cooler strapped to it.

 

So OP, the CPU will only work if its name starts with an 8 or 9 (like i5 8500, i7 9700, etc.).

It's always a good idea to check if things are compatible before you go out and buy them. And if you seek help, be sure to provide all the technical details that may be important, such as motherboard model number and processor model number. That way we can check if they are compatible. But generally speaking, motherboards can sometimes be physically compatible with a processor, as in using the correct socket, but still not work with a given model in a series of processors, which may require a small software update to be made to the motherboard, if one is available (otherwise it will never work with that processor).
