Asus Maximus VI Gene + 4670K @ 4GHz random failures at boot

[Faravid]

Hi,

I recently upgraded from MSI mobo and 2500K to Maximus VI Gene + 4670K.
I'm running the setup with CPU turbo @ 4GHz for all cores without touching any voltage controls.
Only other thing I've changed from the BIOS is turning on XMP profile for my 4+4GB of Corsair Vengeance LP.

I'm having a problem with this, computer tends to boot and immediately reboot and after forcing computer down and rebooting I've been greeted with overclock failed message (doesn't do this every time).
If I enter the BIOS and without any changes reboot the computer (from BIOS) my computer boots up fine and Windows 8.1 runs completely stable without any kind of problems, stress tests pass fine and games run like they should and temperatures are fine.

This behavior is odd as my 2500K ran 4GHz turbo without touching volts perfectly fine. And this 4670K got higher default turbo clock.

Any ideas?

Nice, good to hear

I typically would always suggest manual over the 4 way optimization, that's feature doesn't work to well with a lot of haswells

Mine the only option that doesn't crash the PC is the 4.2 option all the other ones cause immediate crashes, many others have had it happen as well

Currently my 4770k is at 4.5 with 1.4v




And as I said comparing a 2500k and a haswell doesn't really work as the 2500/2600ks some were able to do 5ghz on air which I've never seen a haswell do, haswells its all about the heat you can cool and how much ur chip itself needs

Not to mention due to the newer instruction sets and the way things are handled with haswells even JJ has said it in his videos a haswell clocked at 4-4something is just as fast as a 2500/2600 at 5ghz



But either way again good to hear ur not having issues anymore also nice to see you got the adaptive figured out, I was going to tell ya to do exactly what you did anyway lol

By using adaptive and only increasing the turbo voltage you can have windows power plan on balanced and the CPU runs totally like stock Except it can go to 4.0GHz now and both the core speed and voltage will raise or lower

Switching the plan to high performance will make the CPU stay at 4.0, but for everyday use balanced is the best bet




My 4770k is running 4.5 with adaptive voltage and balanced power plan and ive had no issues for the few eeks I've had it like that

Currently running @ 4.1GHz with turbo voltage up by 0.05V. Max core temp so far 64C.
I don't seem to get it to run 4.2GHz though, I tried to up turbo voltage from 0.05-0.15V, none worked.

If your trying to go higher use manual again till u find stable settings

42 on all cores
Voltage I always start at 1.200v even if I know it won't work
Try to boot
If it doesn't boot raise the voltage, try again
Once you get it to boot I typically run my stress test first in balanced power plan then again on high performance power plan also usually run it more then once on each plan

After that once you get your stable settings you can go back to your adaptive or offset, sometime you may need a little more from adaptive mode to make it stable as compared to manual but that's another way the chips are different

Just need to always watch the temps when testing

Also another way chips are different are haswells sometimes can't be overclocked, some can
Some can't be over clocked while running xmp profile ram, some can

My personal 4770k can't go higher then 4.5 with my h320, it would require more then 1.550v maybe even alot more to be stable and that high is kinda hard to keep cool lol

Update to this issue.
I started to get more and more of those boot failures.
So I disabled XMP profile on my memory and it fixed the issue.

Now my setup is running with memory with XMP profile but voltage up by 0.05V (1.55V) and CPU (4670K) is running 4GHz in adaptive mode with NO VOLTAGE INCREASE. Everything's rock solid so far
