Well if you have the opportunity to take it to 5GHz with good cooling i would try it, i pushed my E5800 1.57V (1.55V actual) but didn't take any higher OC.
That's a dual core at 65W, this is a quad core at 95W, gets mad hot during the Cinebench runs. I've only got one spare 120mm AiO at the moment, so I'm afraid 4.2Ghz is the best I can do right now, at least until I get my Intel DH55 desktop board.
If its cold outside, throw it out hahahaha, well i have quad core Q6600 i tried 1.525V and i can agree with you that temps hit 80*C+ maybe 85*C on full load for 5 min didn't wanted to risk more.
Have you tried Push&Pull full RPM?
One question, did intel only allowed overclocking on 1156 motherboard/socket (with their brand as Intel Desktop board) as i remember Intel=No overclock.
All pre-Sandy locked chips could OC infinitely (as long as you didn't mind RAM freq increase) via the bus. First gen K/unlocked chips (i7-875K, Core 2 Extreme QXxx) allowed you to OC via the multiplier instead of the bus (aka not tying it to RAM).
With Sandy Bridge, bus overclocking was made obsolete, mainly because the bus was lined with the Sata controller, meaning running a high BCLK would risk of corrupting your data. Intel gave users 4 unlocked bins to compensate.
With Haswell, those 4 unlocked bins were removed, forcing users to get a K (unlocked) chip to overclock. I suppose a lack of competition from AMD at the time didn't really help.
With Skylake, the base/bus clock is no longer linked to the SATA interface. Meaning if you were lucky enough to have an older Skylake board, you could BCLK OC the Skylake chips.
The Intel DH55 desktop board was unique that it allowed multiplier overclocking on ANY chip. There's one on Amazon I want that's only $95, can't wait to OC my i3 540 and see how fast I can get it.
