Help! Maximus VI Hero will Not overclock - Bad board or CPU

[snowbro]

I had a professional build my new system with the 1150 Maximus VI Hero MB, I5-4670k, H100i, GTX 780 TI, AX 860 etc..

The computer runs great, cpu idles around 26c, Max temp 50c. Played ARMA 3 for hours on ultra 1440p no problem. However.. having a H100i water cooler & 4670K cpu I planned on overclocking like I had done on 6 other i5/i7's I have had the last 6 years. Never had a problem.

It seriously WILL NOT take any overclock on the multipliers over stock. If I do even just 35x with or without stock voltage, it will not boot. One thing that is weird, is initially I was going to try it at 44 multiplier then set the cpu cache to 42-44, but when I enter in anything and hit enter in the cache, it automatically puts itself down in the low 30's? So maybe this is why it wont overclock? Its like its not a K model. What the heck? I had a local shop look at it for about 12 hours and they cant figure out what is wrong. Is the Motherboard or CPU bad? I need to know what to RMA... : /

- Oh ya: I had given up and tried the AI III suite auto overclock, the very second it started and tried a minor OC. The whole computer crashed hard and went to the (WHEA_Uncorrectable_error) bluescreen. It took the computer 15min to recover and it corrupted 80% of my data on my SSD.

Hello mate

Do me a favour and download CPUz and show me the front tab, and the motherboard tab please.

Ok, the computer is still at that computer shop. I am going in a little later today and I will screenshot the CPUz. I remember looking at everything in the Bios & other monitoring programs and everything looked normal.

did you update (flash) BIOS?

Yes. The pro who is helping me did everything, he reset everything. Discharge, reset, USB flash with new drivers etc..

[snowbro]

Here is the CPUz like you asked me to provide. The board automatically wants to put it at 38x

WHEA errors are instability due to CPU cores or sometimes DRAM - either the CPU is a really crappy sample, or the voltage you were applying was not sufficient for the clocks (could still be a crappy sample).

Here's a short test for you.

1. Clear your CMOS.
2. Load the optimized defaults.
3. Set the Multiplier to 42.
4. Hit F10 to save and restart.
5. Once in Windows, download and run Prime95 with CPU-Z up.

i would actually use Aida64, there have been cases where Prime95 has cooked Haswell CHips, google it. Not even Intel recommends Prime95, not to steal your lime-light chino, just don't want him to take that chance.

Aida64: http://www.aida64.com/downloads Go for the extreme trial version, then when you open it go under tools and hit system stability test.

I have already done this & tried all the different bios versions : /
