Dont change base clock ever.

Only thing I know of is that lowering pll voltage can help stability. Personally I wouldnt go over 1.400v for 24.7. I used to wish I could have a cpu that would do 5ghz at 1.4v or under back when I had a stinky ol 2500k that was stuck at 4.7ghz. Even when I got this 3770k now it does 5ghz at like 1.44v, but I think is it worth it?

The difference is next to nothing.

Ah okay. Right now im at 1.42v @ 4.8, im sure im due for voltage increases as the years go by, when should i sell this chip before the voltages get "too high" and "out of hand to maintain OC"... 1.45? 1.44? I dont get any hotter than 75C on bench, probably 55-60 when gaming.

Temps are well within where i want them and my fans are running at lowest possible fan speed (SP120's). Im sure i can get more cooling power if i raise the fan speed a bit.

Would be unadvisable to upgrade to a 2600k? I hear hyperthreading adds heat when trying to achieve a higher overclock like 4.8, 4.9, 5.0?

Yes i know, the difference is next to nothing..... probably 1 fps or 2..... i just always wanted to hit 5.0ghz 24/7 do you think its possible under 1.45v ? or is that like in the realm of having a "golden chip" ?

If your not stable at 4.8ghz at 1.42v its highly unlikely you will get 5ghz at 1.45.

I would say 5ghz at 1.4v or lower is above average, i see some people doing it close to 1.3v, now that is truely golden. Unless you have money spare i woulsd just settle for what you have. I wish i could go back and keep my old naff clocking 2500k, it was perfectly fine and i would have saved so much money.

What the temperature of a 3570k or 4670k running at the same clock speed as my current 2500k ? Currently im seeing 77C max on bench on water, am i going to see like 87? 97? without delid?

At or above 90c for definite if you run it at 1.42v regardless or air or watercooled.

Delidded though it will be much lower. Ivy brudge overclocking is also considerably easier than sb, all you need to do is change cpu multi and vcore.

Ahh jeez chasing this "number" is going to be a lot harder than i expected... From my understanding, i just had to turn on a few things and then change mulitplier and vcore with SB.... i thought IB was harder? LOL. But that sounds pretty easy. I might think about going for a 3570k and delidding it.... i dont know.... seems so expensive and so risky and loss of wonderful Intel warranty for chasing a "number".

I'll have to think about this for a while as my funds are tight being a college student and all (no crazy paying job) -- yet.... rolleyes.gif

While using offsets is there a way to increase the minimum vcore while not affecting the maximum? I seem to be stable at 1.312 but not when it drops to 0.928 or at least during the transition, LLC is set to ultra high (Asus Mobo).

No IB is much easier, haswell is the most difficult I believe.

Try turning C1E & speedstep off. Although im not sure that will work, when using manual these settings make ti so the speed and vcore dont drop at idle.

That is the whole point of using offset, to make speed/vcore drop at idle...

I want it to drop just not so low, the offsets seem to have intervals of 8mv.

offset
-30/35 (1.328-0.944)
-40/45 (1.320-0.936)
-50/55 (1.312-0.928)

From what I can tell 1.312 is enough vcore at the high end but the 0.928 dip is too low. It seems to need a minimum of 0.944 if that makes sense so I need 1.312/1.320 and 0.944

Thanks for any advice by the way.

if you dont want it to drop as low, you have to reduce the llc.
yes reducing llc will cause your load vcore to be lower. raise your offset.
