H110 watercooler

I have currently overclocked it to 4.3 ghz at 1.310 volts.
Using Prime95, the highest temperature I've gotten is 52 C.
Is it safe to bring the voltage and/or ratio up more? The voltage number turns yellow above 1.3 volts, and I recently had some major instability after overclocking with similar settings.

I'm using AI Suite III, but if I could get step by step directions for using the BIOS I'd do that if it is better.

Using the automatic overclock that the AI Suite has it will crash after a minute or two of Prime95.

Thanks for any help you can give.

I wouldnt use any auto-overclock feature...but would let the voltage auto-adjust, while you specify the multiplier.

Not sure if you are misreading what you are seeing or what but 1.423v is a LOT. 4770k is pretty hard to fry but you are running enough voltage to do it....no way that thing is at a safe temp if you are really pushing 1.423v through it.

According to AI Suite III (came with my motherboard) and Speedfan, it got up to 88 C after running Prime 95 for about half an hour. Being that no normal program or game will push it as much as Prime95, which is made just to push temps, I think I'm safe. As long as temps don't exceed 80 C in normal use I should be good, right?

Well, is that fixed, voltage or adaptive?
Keep in mind. A. Speedfan doesn't have a setting for Asus Z87 A, so your temps there are probably not accurate. AI Suite gives the temp of the socket not the core. You may want to check it with a more reliable program. CPUID Hardware monitor will give accurate temps for that board.
B. While no normal game might push it as hard as prime, there is still the fact that anything putting the CPU under load is going to push 1.423v through it anyways. I haven't personally tried it but I don't think that cooler can dissipate that much heat. I dunno maybe it can; I would def check hardware monitor to verify though.

Unfortunately that could be the case.
But don't auto overclock !
Set it up manually.
Every single quality review I've read has found that OC utilities apply too much voltage to the cpu.
It doesn't matter what mobo maker!
It was all of them.
