[SOLVED] Raising a current i5 3570k overclock (Bad chip?)

Hello all,

So I've been having issues raising my overclock with my 3570k. I've had the chip at a 4.2ghz overclock for over a year now, with its voltage being WAY above the average, like around 1.3v; I HAVE to keep it at that voltage for a stable clock. Now, fast forwarding to this year, I decided to upgrade my cooler just this week from a Hyper 212 EVO to a Corsair H100i, and attempted to go from 4.2ghz to 4.4ghz, regardless of what the voltage was.
Well... it just started getting ridiculous. My voltage NEEDS to be above 1.4v to be the least of stable for a good overclock at 4.4ghz, otherwise it's crash galore inside Windows.

So... where exactly should I go from here? Should I just keep it locked at 4.2ghz, with my cooler not taking advantage of what it's for, or take the risk of making my voltage above 1.4v?

Thanks to whoever can help me out, appreciate it.

Yeah, C1 and C3 were turned off in my BIOS, I didn't mess with much on the power side. I'm using an Asus P8Z77-V

Ok you might want to disable all the power options so that they are like off or on high performance. Also does your motherboard support manual overclock voltage entering?

Yeah it's got a manual option, I followed most of this guide last year to start overclocking, shows basically all my motherboard's settings

So do you mean you can enter a manual value like 1.345 and that the motherboard will not change it after? Or do you mean you can only go up in like 0.0006+ each time?

Yeah, both the CPU ratio and voltage I entered manually, I don't think (at least) that it goes up by itself. Other words, it's not in offset

16gb of Corsair Vengeance DDR3-1600, and yeah I did tests with memtest86 the other day with no issues. BUT however I did get BSOD's relating to RAM like "page fault" a few times...

Ah, alright I'll give it a shot. Should I start with low voltages then?

Chips are a lottery, i made a recent upgrade to a 3570K from a 3450, and just trying to figure out the limits of my new K CPU, i found it can reach 4.4 - 4.5ghz completely stable with just 1.14v and maybe it could do it with an even lower voltage.

I swear mine is the probably the worst out of the entire i5 batch of chips. It's sitting at 1.144v on STOCK. After I remount the cooler because of temp problems, I'm gonna attempt to O/C again, but it's really disappointing I spent all that cash for something that should be sufficient for at least a SMALL overclock, if none at all.

I tried raising the memory voltage to 1.65 and Prime95 worked for about 2 hours until getting a blue screen related to RAM (non-page with error 0x50).
I managed to keep my CPU voltage down though, 1.24v on 4.2ghz, but still my RAM is giving me issues.
Any other ideas?

Never mind everyone, I was able to get the RAM stable by setting the VCSAA to auto. Idles are running at low 30s/mid 20s at 4.2ghz
Thanks for the contributions and help, though!
