Hello I wonder if someone could give me their opinion on the following please:

I am trying to overclock the 3570k using an Asus Sabertooth Z77. I have updated the bios and chipset drivers.

To get to 4.3GHz I have to increase the voltage to 1.330v, which is displayed as yellow text in the bios so I know this is getting high.

I have done quite a bit of reading about overclocking and some people have been able to achieve 4.3GHz+ on stock voltage.

Currently I am running at 4.2GHz and 1.330v. I can run AIDA64 for hours with no problems and temperatures don't exceed 75 degrees C. However I just tried to play BF1 and the game crashed, followed shortly afterwards by the whole system.

Could it be that the motherboard is faulty? Perhaps something to do with the VRM?

I can't increase the voltage any more than this and if I increase the frequency any more then the system becomes unreliable and unstable, and hot.

I feel bad for the old 3570k I had previously. I ran far higher voltage through it than that! (not saying that was a good thing to do.)

AIDA64 isn't the most taxing of the stress tests that are available, so it might not be uncovering any instability that is present.

Is there a core clock and voltage you have found that is 100% that is stable? You might be hitting your ceiling.

What were your temps like while playing BF1 and is your GPU\RAM overclocked as well?

Hi thanks for your reply.

Gpu and ram are standard. Gtx 1060 and ballistix ddr3 1600.

The system became increasingly unstable so I reduced the core clock and voltage all the way back to stock, where I continued to experience total lock-ups. Temperatures were not high and I wasn't running any tests when these lockups occurred.

I then tried a i3 3220 at stock 3.3ghz. This also locked up multiple times and totally without any tests running

So then I tested the i5 3570k and the i3 3220 in another board (asus p8b75-m lx) and both completed Intel burn test with no freezes. I tested on prime and aida but I consider IBT to be the most strenuous.

So I've concluded that the board is knackered and probably couldn't supply the cpu with the correct/stable voltage that it required. Even when I set the voltage to manual @ 1.330V it would supply over 1.4V so I quit the trial and error before that mobo destroyed the cpu as well.

Perhaps the cpu is not a good one and perhaps my psu is also to blame. But the fact that the motherboard could never stabilise an overclock makes me inclined to believe it's better off in the nearest bin.

It's old and crap technology anyway.
