i5-3570k Hitting a wall?

I am having problems with my IB chip right now, I had it stable at 4.3 GHz but then I flashed a BIOS update and forgot to write down any of the settings. Anyways, following the same methodology as before I took it back up to 4.3 from stock (had the voltage at 1.275v, LLC set to Extreme) but I can't seem to get it stable (maybe I was close before but not entirely?). So any advice would be appreciated.

System Specs:
i5-3570k cooled by Zalman LQ-315
Gigabyte GA-Z77x UD3H
Corsair Vengeance 8 GB 1600 MHz Cas 9 @ 1.5v
Gigabyte Windforce GTX 760 2 GB

My IBT temps also seem really high, and I have been monitoring temps with HWMonitor and voltage/frequency by looking at CPU-Z.
Running IBT on stock settings I have these:



Side notes: My cooler is mounted on the rear exhaust port, with the Zalman fan between the case and the radiator and a case fan on the other side of the radiator, both on intake. Could the case fan be hurting my performance there? And does anyone know of good/quiet fans I could mount on my cooler because the one I have now is way too loud (45 dB from where I am sitting).

Wall of text done, thank you for any answers I get.

as for the water cooling part i'm not too sure but, you should be able to reach the same overclock without issues.

i do remember some BIOS versions were better overclockers over others for the Z77X-UD3H but, it should be similar.

i'm sure your 3570k will be capable of a higher overclock; just try to keep temperatures under 75C and CPU Voltage(Vcore) under 1.3v when using the PC for daily use.

Thanks I will try a different version. I originally flashed the new BIOS because I had a problem where all my USB ports lost power, then I had about 45 secs to shut down my PC or it would freeze up and I would have to hard reset.

Tried it on the backup bios, and I didn't find any difference at all.

have you tried flashing the BIOS to another version?

I have it "stable" (I test stability by 10 passes IBT at Very High well also playing League and Minecraft) @ 4.2 GHz, LLC set to Turbo and Vcore is 1.2

I don't think it is the BIOS as that would mean I tried 3 different bad BIOS flashes.

Strangely, my temps are lower than they were at stock. I'm guessing this is due to default being unoptimized.

Did you change to the gigabyte UEFI version?

from what you're saying so far, i don't think it's the BIOS either, i think you may just be forgetting to do something like changing a setting here and there. you'd just have to keep testing the settings to confirm if you didn't follow a overclocking guide.

have you tried to use the automatic overclocking feature in the BIOS (or it may be a application that runs in the operating system)? it may help you narrow down a BIOS setting you forgot to change. it's not generally recommended due to the high fixed CPU voltage the feature applies but, you can just change the CPU voltage right after the overclock is applied.

So, not changing anything (that I can tell), I have achieved a stable 4.3 GHz OC at 1.275V. (Before it was something like 1.295V)

I did literally nothing but switch to old BIOS and then back again to the new one, and I guess I must have done something wrong. I don't understand. But I am happy.

On a side note, I ordered a pair of Scythe GT AP-14s for my radiator on the advice of some people I was talking to elsewhere.
