i5 2500k Overclocking information

Here's the OCUK advice on the matter:
http://forums.overclockers.co.uk/showthread.php?t=18227651
"Core Voltage - Not recommended too exceed 1.38v, doing so could kill the CPU, we therefor recommend a range of 1.325-1.350v if overclocking."
Don't know if that still applies though.

Reply from an intel guy called Adaolfo_Intel. He says 1.52vcore is the max recommended. Im at 1.45v. Im happy with his answer.

The guy is speaking mince, 1.52V is the maximum VID value the VID register can hold, not max safe Vcore. The Intel datasheet for SB or IB does not state a value for Vcore.
Well, intel guy v You. sorry mate, il stick with intel guy. Show me data il believe you, until then, im sticking with Adolfo to be honest.

Have a look yourself, quote me what page it says max safe Vcore is 1.52V. For reference you can find the max VID value of 1.52V on page 75, equivalent to a register value of 11111111 in binary.
Not only is the guy wrong, but he could also be giving people information that could lead to them damaging their CPU.
Fair enough Jokester, I cant make head nor tails of the data sheet 
Il go along with whatever you say. With that in mind, just backed my clock down to 4.5ghz on 1.37 volts. I wasnt trying to be funny btw as your reply seemed a tad edgy.. If an intel guy tells me something, im rather obliged to believe it as there the experts (apparently)

I wouldn't worry too much about voltage, if it's retail you get 3 years warranty, don't think I have ever owned a chip that long, also I have never needed to use a warranty on a chip and have seen no reports of cpu's dying.
Not sure if its retail with 3, or OEM with 1. It was part of a prebuilt system, of which the cpu, ram and ssd are still here lol.
Its an ocuk chip, so they would cover it i guess.
my i5 2500k runs @ 4.5Ghz when the pc is on, the voltage is 1.35. It has been stable since the day i built it.
IMO 4.5Ghz - 4.8Ghz is plenty fast enough, and i personally wouldnt take the voltage above 1.40 (but thats just me)

Ive lowered everything, volts are at 1.38v now and clock is 4.5ghz. Enough of an oc i guess
It really irks me to see the 1.52V is the safe max Vcore quoted about the place, especially by an Intel rep!Fair enough Jokester, I cant make head nor tails of the data sheet

SB-E Datasheet:-
http://www.intel.co.uk/content/www/...-2011-datasheet-vol-1.html?wapkw=i7+datasheet
Page 55 - max VID = 1.52V
Page 60 - max vcore = 1.4V
Not sure to be honest, why would they reference 1.52v so much?
Also VID, ''VID is the recommended voltage the processor should be running at at the current power state, this is a predetermined value, programmed by the CPU manufacturer.''
Which intel being the manufacturer have said a max of 1.52v may be required, why would they do that when they could have set a max VID of 1.4v?
Also has anyone been able to run one at 0.3v?
OcUK recommend 1.425v as a max http://www.overclockers.co.uk/showproduct.php?prodid=CP-360-IN&groupid=701&catid=6&subcat=1275

The VID register is just an 8bit register that holds the CPUs VID value, 8bits gives you 256 values to play with. If you start at 0.3V and go in 0.005V increments you end up at 1.52V with the register full. The SB-E datasheet even gives a value for max VID a chip will programmed with - 1.35V.
Edit: 00000000 = 0V, 00000001 = 0.25V, 00000010 = 0.255, and so on till 11111111 = 1.52V
