Asus Maximus VIII Hero Q-Code 18 Error

[PSPlover]

Hello Guys

I recently built my new pc with the following parts :

CPU : i7 6700
RAM : 16GB DDR4 G.Skill Ripjaws F4-2400C15D-16GVR
Power supply : be quiet! Pure Power 10 CM ATX 400W PC BN276
Motherboard : Asus ROG Maximus VIII Hero
Graphics card : NVIDIA GTX 650 (yes, I still use my old card because new ones are really expensive)

I was happy with it until I powered it on. Every time I start my machine the Q-Led displays different codes and then gets frozen on 18.
I have already removed the CMOS battery and reseted the BIOS. I also put just one RAM module inside but I still get the same error.
According to the manual code 18 means : "Pre-Memory System Agent initialization"

What should I do now? Is something broken? Can I fix it?
I hope that you guys can help me out

Hi PSPlover

I would upgrade your psu.

How does it go if you remove the gtx 650 and try with the onboard graphics ?

Have you tried clearing the cmos and updating the bios ?

Hello Nate152

I would upgrade your psu.

Why?

Anyway, here's what I have found out : If you have only normal parts in your computer then read this : http://www.tomshardware.co.uk/answer...9977/code.html
Try clearing your CMOS and check for bad RAM or bent pins on the motherboard.

I however had a different CPU! It was an i7 6400t QHQG (Engineering sample) and I read on an russian forum that the CPU isn't supported in the newer bios versions. I just had to downgrade my bios version with the asus flashback feature on bios version 2202. Now everything works fine
If you want to overclock the chip then you just have to download the modified bios for this CPU on the russian forum : https://forums.overclockers.ru/viewt...8504#p14378504 (Use google chrome for translation)

Here is a general discussion about the chip : http://www.overclock.net/t/1599531/s...verclock-on-es
Even a YT video : https://www.youtube.com/watch?v=Ak-Z7T1kOoI

I am happy now and I hope that my post will help others in the future.

Why wouldn't you have told us the correct cpu at the beginning ?

Anyway, good to see your problem is solved.
