Hey, I'm fairly new to desktop CPU's, and overclocking. I built a gaming rig in February consisting on a 4770k, EVGA GTX 780 SC ACX, and an ASUS MAXIMUS VI Hero motherboard.

Here's the issue; whenever I overclock my CPU to 4.2-4.3GHz, I will hit 60c in Battlefield 4 (using an H100i). But then when I try and go for 4.4, I hit about 65c. Now heres the thing I don't understand. At 4.5, it will peak at 70c, but average about 55-65c.

If there is only an 8c difference from 4.3, to 4.5, hell yeah I want to run my 4770k at 4.5. However I just crashed in BF4 when it was running 4.5 at 1.290v. My all time goal was to keep it below 1.3v and 70c in game. Now, if I crashed a few hours into a game, then it most likely means that I only need a few more voltage raise, such as 1.310 or 1.320.

Heres my question. Ive been reading that the "safe" voltage for haswell is 1.3 and below. However, what will be the downside of using any voltage above 1.3, such as 1.33-1.35? And how long should the lifespan of my 4770k be at 1.3-1.320v?

Im still testing my overclock at 4.5, but I seem to crash will everything below 1.295. I am willing to go up to 1.320, but im just concerned about the lifespan of my 4770k at that voltage.

All voltage is set to Adaptive.

From the Haswell Death/Degradation thread:

CPU: i7-4770k

DELIDED: YES

REPORTED CONDITION: DEAD, R.I.P., MUERTO, KAPUTT

CAUSE OF DEATH: EXCESSIVE VOLTAGE, 1.37-1.4+V VCORE

HOW LONG OVERCLOCKED: Approx one (1) year

OP DESCRIPTION: I had ran a daily overclock of 4.4, but that wasn't the problem. My voltages were off the charts. My vcore was set on adaptive instead of manual and it would range anywhere from 1.375 to 1.4+ My input voltage was 1.9 and my uncore voltage was somewhere up there. I don't remember. I had this chip delided and OC'd for almost a year.

THREAD: http://www.overclock.net/t/1475351/i-think-my-4770k-gave-out

WARNING: HardOCP.COM state that anything over 1.35V VCORE 24/7 will degrade an Haswell pretty fast when conjoined with heavy loads and lots of working hours every day.
