Just recently started overclocking....haven't been able to wrap my head around a few things, but am working on it. Anyway, on to the good stuff.

Hi Vellinious , Welcome to the OC3D forums.
Your voltage is a bit high , what are your temps .
Post full system specs , I know there are members here that can give you some pointers.
Tom also has a overclocking guide if you haven't already watched it , here is a link.

I get 4.5 @ 1.285 stable in Prime 95 for 4+ hours. In order to run 4.6 in P95, I have to up the voltage to 1.350. At 4.7, I've only been able to get it stable in P95 at 1.405 volts. Yeah, the voltages are high, but it's what I have to run to get them stable.
At the 4.7 clocks, temps are topping out in P95 at 76c.
At 4.6, topping out at 68c.
At 4.5, they're topping out at 64c.
I've only really messed with the multiplier and the CPU voltage, so if there's anything else I can do to bring those voltages down, so I can get a bit more out of it, I'm all ears. I haven't been able to get 4.8 stable using just these two settings. But....they're the only ones I really understand, so they're the only ones I'm not nervous about messing with. I've heard people talking about lowering the CPU volts, and raising PLL voltage, but....I'm not really sure what that does.
System Specs:
i7-3770k
EVGA GTX 670ftw 2GB
16GB GSkill Sniper 2400
ASUS Maximus V Formula
Ultra X4 1050 watt PSU
XSPC Raystorm CPU block
XSPC Raystorm GPU block
XSPC 120.2
XSPC 120.3 crossflow
Dual D5 pumps, with bitspower mod top and 250mm res
Fractal Design Define XL r2, heavily modified

It's surprising to me that the temperature difference between 1.350V and 1.285V is only 4°C. Anyway, temperature isn't the only thing to consider, voltage on it's own can be degrading to a CPU, so it's best to keep within the safe range. If those extra 0.1-0.2GHz makes the voltage have to go outside of the safe range, it's not worth doing to be honest, and you will barely notice any difference in performance anyway.

Ok. I've been using AI Suite II sensor recorder, and I think the temps it's giving me are wrong. I started using HWMonitor, and I'm getting a lot different readings.
Also, played around with some settings in the BIOS.
Speed step: on
CPU Voltage: manual
CPU Fixed Frequency: 500 (was 300)
CPU Current Capability: 140
Load Line Calibration: Ultra High (was High)
New measurements, using these settings with HWMonitor:
4.5 @ 1.275v / P95-8k passed 74c / IBT-10 standard passes 74c
4.5 @ 1.265v / P95-8k passed 74c / IBT-10 standard passes 73c
I'm going to have to start all over.....I'm going to keep lowering the voltages at 4.5 until I can't lower them any more, then start again with 4.6. Hopefully I can get 4.5 stable at or around 1.25v. I'll post again tomorrow with what I find.

Ok. So after playing around yesterday, and well into the night, I found some numbers...finally.
4.2 @ 1.140v is rock solid steady - 10 passes of IBT, peaked at 64c. 3 hours on P95, peaked at 61c. (this will be my 24/7 clock) *this is with speed stepping on
4.3 - I didn't bother
4.4 - who goes to 4.4...grow some nuts, go ahead to 4.5
4.5 @ 1.255v OCCT for 30 mins peaked at 68c.
4.6 @ 1.325v OCCT for 30 mins peaked at 72c - I can bench here
4.7 @ 1.405v - this voltage is too high for my taste, so I didn't even bother once I got above 1.4.
Summary: I just got a VERY average, to below average chip. Sucks, but....I didn't win the lottery.
EDIT: It is a shame, truly, because I do have some pretty epic cooling.....
