Asus Z370 A will not boot

[Quint256]

BUILD:

MOBO:ASUS Z 370-A

CPU:I9-9900k

GPU:GTX1080 founders edition

Ram:32 GB trident royale 3000MHZ DDR4

Psu:Corsair HX850

COOLER: hyper212 evo

 

Put together today but no post. Have tried dvi and hdmi getting no signal messages on both screens plugged in though mobo and gpu separately. Have contacted asus and they have said the ram is incompatible but i have seen the exact same setup working. Have tried every ram combination possible.  Any ideas what could be wrong?

Mediocre board and cooler for the i9 9900K

 

Any ways did you assure the motherboard BIOS is updated?

Is there a way to update the bios without another cpu? Only other one i have available doesnt fit the socket

Some higher-end boards have the ability to update the BIOS without a compatible CPU installed. I don't think the Z370-A is one of them. If there's a computer store near you (like a Fry's or a Micro Center), they might be able to flash the updated BIOS for you, or you could buy a cheapo Celeron G3920 and resell it when you're done, but let's start from the beginning here. ASUS' customer support is as useful as a bathtub full of gasoline when you're already on fire, and they come up with any and every reason to make it not their problem.

 

So, from the top, disconnect and reconnect all of your cables. Make sure your connections are good, then try to boot. Does it work? If so, yay! Easy problem!

 

If not, pull out every stick of RAM and put one stick back into the DIMM furthest from the CPU. Power up. Does it POST? If not, try the next stick. Does it POST? If not, try the next one, then the next one. If none of the RAM gets you a POST, try the same procedure on the remaining three DIMMs, working from the outside in. If none of the above works, you have other problems. If you find that one slot or one DIMM works, continue the process of elimination but leave the good RAM in the good DIMM. Troubleshoot your way towards figuring out which DIMM isn't reading.

 

If you can get your hand on another stick of DDR4, any DDR4, give their claim that the RAM is incompatible (it's not) a fair shake by trying it with that.

 

If you find that some DIMMs work and some don't, pulling up your CPU to look for a bent pin isn't a bad idea.

 

If you go through all the troubleshooting steps and it won't POST at all, it's a safe bet that your board needs a BIOS update to read a 9900K, and that takes us full circle right on back up to my first sentence.

I am going to RMA the board and have them update it for me.
