Solved

My ASUS Z97-AR can not run with the Default BIOS settings.

I had originally posted here:
Tom's Hardware -> Forum -> Systems -> Problems with Asus z97
With the intention of helping the OP of that thread, but apparently I'm having more issues than I'm aware of.

My first post there was a reply indented to help fix anyone that had the same problem as the OP and myself. I thought I "Fixed" it by manually setting the multiplier down to a stable number. The number that Intel intended it to run is 35 right?

I might be completely misunderstanding the Moderator Tradesman1, but are you telling me that I should be able to run my PC at the default overclocked settings? Am I even saying that right? I'm also confused on how locked processors can be unlocked for "turbo-boost", as you say, but that's a whole different topic. I'm not an overclocker, so maybe 3.9 has something to do with the bus speed and not the multiplier? I was almost certain that locked processors had locked multipliers.

Please let me know what I'm missing and why my system has been running completely stable with a max multiplier of 36 instead of the default 39.

Stable CPU-Z:


Unstable CPU-Z (Default BIOS settings)


With my multiplier in the BIOS set to 36 instead of the default 39 or 42 with the AI suite 3, it has been running stable with no crashes for 2 days.

With the multiplier set to default, it crashes whenever (at boot, surfing firefox, or gaming). It might run for an hour, and it might run for 1 minute if it boots at all.

So, my main questions are this:
-Am I missing something?
-Did I not "fix" my issue, but somehow bypass the real issue?
-Should I be able to run the default settings with the OEM heatsink? If so, then I would need help troubleshooting as I know nothing about ram timing and some other hardware settings.
-How can a locked processor be used in "turbo-boost" mode when it's... Locked?

Here are my system specs:
Windows 10 Tech Preview
Also Tried Windows 7 64-bit for a while

Brand new parts purchased this week:
-GTX 980 (using the GeForce Experience with the most up to date drivers)
-16GB Corsair RAM (CMZ16GX3M2A1600C10) (on the QVL list from asus for my board)
-Intel 4690K
-Refurbished Asus Z97-AR (Drivers downloaded from asus' website this week)
Older parts from previous main gaming PC:
-PC Power & Cooling Silencer 760Watt PS with 62 amps on the 12V rail
-128GB Samsung 840 Pro SSD for windows
-4TB regular drive for programs and games

Thanks for any input anyone might have!

  1. Yea I wanna know if theres a solution to this as well, because I have the same problem after overclock. When I run bios default it doesnt boot to windows. My monitor would turn off after the windows logo. a solution is to overclock it again...

    I'm glad to hear that I'm still not the only one that can't run at default. Also, as I explained on the other thread, there are about 5 or 6 Asus Z97-AR motherboards that were returned to my local Microcenter Store. I'm betting there is something wrong with the default settings, but I'm still open for any ideas to try out.
  4. I tried everything, cmos default by pooping out battery reflash bios. Nothing seems to work loool. Hopefully someone knows the solution. I dont think its the bored because I have a gigabyte G.1 sniper 5 board. I feel like the processor it seem seems to be more used to higher speeds overtime or something. haha.

    Uninstall the Asus AI Suite, make sure you have the latest BIOS, if you already have it reset the CMOS to put mobo to defaults, the 4690K base is at 3.5 if you want it at that go into BIOS and turn turbo-boost off. Turbo boost will automatically OC the CPU up to 3.9 if it thinks it''s needed, when you set the base to 36 and turbo boost is on and can 'boost it up to 4.0. The stock cooler should 'be fine' at the stock 3.5 and even with turbo boost, I myself don't like those fans and throw them away, they are load and don't really work well, can pick up a number of inexpensive air cooler for less than $40 that cool better and are quieter.

    I uninstalled AI Suite and updated the BIOS yesterday. I set the defaults, then I went and changed this:


    Other than that, I see nothing that says "Turbo boost" or Turbo anything.

    I'm happy to run it at 35 or 36 multiplier. It seems to be working fine. I'll keep it at 36 unless I have problems unless you think it should run at 39 for some reason. Strange that the default is not stable.
