Voltage help with first overclock (2500k @ 4.5GHz on biostar TZ68A+)

post #1 of 5
Thread Starter 
Hi,

SO last night I attempted my first overclock with my 2500k using a biostar TZ68A+. I actually follow a guide from tomshardward since windwithme had use that exact combination.

I haven't ever overclocked before, but I had read up on it a lot and thought I kept hearing you want the voltage under 1.35V for the 2500K. I followed the guide on that page and went right to 4.7Ghz. I tested with Prime95 only for about an hour and temps were getting right close to 80C on two of the cores, the other two were slightly under. I'm using a Corsair A70 for cooling. The voltage still seemed high though, so I turned it back to 45, so all the cores run under 80C at load - although I haven't run it for hours and hours.

Before I do that, I want to make sure the voltage isn't going to be damaging the chip. Like I said before, I'm a complete noob at this - but I attached a CPU-Z screen if someone can look at it and tell me what needs tweaking.

VID from Coretemp is 1.3761v, voltage is 1.452 on CPU-Z.

Think I might have figured it out

How did you get it to OC that high? I can only get mine to 4.2, no matter what I change it wont go any higher.
Could you what your settings are?

Just use this: http://www.overclock.net/t/968053/official-the-sandy-stable-club-benchmarks-stable-rigs-guides-inc-spreadsheet

Read everything in the first post and anything linked from it, then /search thread/ for info on particular settings, errors and whatever. That's all I needed.
