3570k on Z77-DS3H

[Rakehellion]

I have an i5-3570k a Gigabyte Z77-DS3H.

I've got options for Vtt, PLL, and IMC voltages. No matter what I change the voltage to, if I increase the CPU ratio beyond 42, the system won't boot past the motherboard splash screen. I reset my motherboard to default settings and reboot, Windows tells me my installation is corrupted.

Is there something else I need to change?

I left the memory at 1.5v.

I can set the CPU to 1.3v and it won't go past 4.3GHz, but 4.2GHz works fine at stock voltage.

What cooler are you using? The main thing which is important is the CPU voltage. I would suggest tweaking with manual voltage first and then "dialing" it in with an offset voltage later. You do not want to run a high manual voltage 24/7. So find a manual voltage that works, and then find an offset voltage which allows your cpu to idle at lower voltages. 1.3V on Ivy will require a good cooler. I certainly prefer closed loop liquid coolers, for no other reason than they're REALLY SMALL with only the rad taking a case footprint. I prefer this to having a mammoth Noctua NHD12 covering half of my motherboard.

As far as IMC, VTT, and all that crap, i'd say it's vastly over-rated for OC'ing. In my experience (subjectively) with Haswell and IVB, processor voltage trumps everything. This is the main setting you want to mess with. Do not add variables which can compound things. Leave your memory at STOCK settings for the time being, worry about overclocking the memory later. But do understand you need a versatile cooler with both IVB and Haswell. I use the H100i on my primary desktop rig. If your cooler is terrible, your computer will certainly lock early on at 1.3V.

1.3V is also pushing things a bit. I'd aim for the 1.25 - 1.275 V range, BUT, again, GOOD COOLER required. Start with your CPU core at 1.225 to 1.25V. Understand that 1.3V is pretty excessive on Ivy - i'd definitely prefer the 1.25V range where possible, with 1.275V being the absolute upper range.

Try increasing power limits if possible.

If that doesn't work it's either the chips limit or the motherboard isn't up to it, because normally you shouldn't have to change anything besides multiplier and vcore for 4.2 Ghz.

I'd say you're right. In fact, I'd probably put my money on the chip's fault. My experience is with Z87 cuz I didn't get an Intel rig until fairly recently, but my Haswell i5 is running at 4.5 GHz on what I'd consider to be a high low-end board. I'm running on an MSI Z87-G55 if you wanted to look at it. My lack of experience tells me that with an overclocking-compatible board, the chip is the limit of the clock speed. Might have just been unlucky
