Overclocking 4930k

[Negnelfi]

Looking for a little advice with OCing my 4930k. Fairly new to the whole OC scene. Specs are as follows.

Intel 4903k
Rampage IV Extreme Black Edition
16gb Corsair Vengeance Pro 2133Mhz
KFA2 GTX 770
Corsair RM Series 850w Gold
Coolermaster Cosmos II Case
Cooler Master Eisberg Prestige Jetstream
XSPC EX240 120mm Radiator - Black

Screenshot below shows where i'm at so far. 4.4 is stable with vcore set to 1.300. XMP profile is enabled. Near enough everything else so far is still set to to auto. When setting ratio to 45 on the same vcore i'm bluescreening within a few minutes. I'm hoping i'm wrong here and that i'm missing something but from what I've read I get the impression that not being stable on 4.5 at 1.3 vcore is a bit of a ****** chip. Any input appreciated.

With my cpu 4.4Ghz is stable at 1.31 volts and 4.5 is stable at 1.38volts. Temps will get higher and higher at this point until you hit the 80c+ and should really stop. My cooling is good up to 1.4-1.45volts. I should be able to get 4.6Ghz in the 1.42 to 1.45volt range (could be as high as 1.47volts) but this is well above the 1.35volts that really should be the max for these chips.

If you have not already done so, try strap at 125 and see if the vcore drops. Stats from realtemp or CPUID HWMonitor are better here than the app you are using. Your chip is a 4.4Ghz one with safe vcore, to get to 4.5Ghz you will have to take a risk. Some chips work away happy at volts like 1.47volts for years but others don't last long and degrade fast (these are the reports I read online). I don't think you have to cooling to go much higher than 1.35volts. Most people report that 1.4volts is safe but intel states that 1.35volts and below is best for these chips. Hell up to 1.295volts is yellow in BIOS's for a reason.

Now you can go for prime95 stable or if you care only for games and don't care about data corruption you can use realbench, aida64, handbrake (note its only a few volts above this that you will be prime95 stable) or games as tests. If you go for prime95 or handbrake stable your going to have an overclock one multi less or even more.

Stable in games I am at 4.6Ghz within 1.4vcore or prime95 stable at 4.5Ghz within 1.4vcore. Don't hammer the CPU with prime95, only test when you feel it will pass. The idea is to test once for 8 hours and then leave it and test every day things like games.
