So how difficult actually is it?

... to take a brand new i5 2500k with an Asrock Extreme gen3 mobo, silver arrow cooler and overclock it to around 4.8ghz?

I have never overclocked before, and tbqh am overwhelmed with even the beginners guides.

Is it literally just a matter of tweaking a few values, running a benchmark and hoping for the best?
 
If you have a CPU capable of hitting 4.8GHz relatively straight forward - but you may have a CPU that will only hit ~4.5GHz no matter what quality cooler you strap on to it or how many volts you're prepared to put through it.

Luck of the chip at that clock - plus BIOS tweaks of course...
 
Like Plec says, its the luck of the draw. Start with a lower clock, get to know your way around the bios, and take it up gradually, the more confident you get changing settings, and their limits the higher you will get your chip. So far its taken me nearly 4 months of fiddling to get confident enough to change some settings off the cuff, and be quite expectant of the results. Started out at 4.3ghz, currently at 4.950ghz and still under 1.38v :-)

Plug away, look at guides of which there are many, if you hit a major issue, there are dozens of E4G3 owners on these forums.
 
Yeh. Ive heard of these "Golden Chips" Or something. SO its completely random? Youve got no idea of what you are ordering really?

Coo. pgi947, what cooler are you using?
 
There are no known 'golden' stepping revisions (though its thought the D2's are better clockers than the D1's, still unproven) and no 'golden' batch numbers. The majority of chips will do 4.7-5.0ghz, but at what voltage is the real question.

My chip may be classed as 'golden' but I prefer to look at it as a lucky draw, over 5ghz requires a major voltage bump.
 
Right. So basically, the more voltage you pump through, hotter it gets, eventually bang if you keep going.

So the key is to get highest clock with lowest voltage?
 
Pretty much yes, generally speaking you should try stay below ~1.45v, most prefer to stay below 1.38-40v. Two things are the main culprits for heat, clock speed and voltage, so one can't be helped, but lower voltage at higher clock speed would still yield some very good temps, especially with a silver-arrow.

At the moment (still testing) I'm at 103x48 for 4.950ghz @ 1.36v (please no preachers on blck overclocking, I'm fully aware of the risks), other members on here with a similar setup require 1.5v to get those speeds, so luck of the draw.
 
Ok. I can see there is a beginners guide to OCing on the forum, but could anyone link me to any video guides if possible?

Cheers
 
mini hijack.....in that video he mentions just upping the power limits but doesnt mention what safe limits there are. Also, the asrock has different current limit settings than other boards. The P8Z68 for example, has primary and secondary plane current limits. What do these do?
