I'm not surprised at all... with mine:
4.5GHz @ 1.27V (Stable)
4.6GHz @ 1.32V (Stable)
4.7GHz @ 1.448V (Working... I think stable)
4.8GHz validation only @ 1.51V
4.9GHz validation only @ 1.56V
...
5.0GHz - utterly impossible.

Even at 4.7GHz @ 1.45V my temps are fantastic (hottest core on a Prime95 with 90% RAM used hits 72C over 12hr runs)... but doesn't matter - the chip is completely voltage limited.

I'd say if you can't hit 4.6GHz at less than 1.25v you'll never see 4.9GHz stable (even at 1.55V) and at 1.33V for that speed you'll never even see windows desktop most likely at any vCore.

This was my best - and it crashed instantly when the cores were fully loaded:

Any other tweaks you guys would suggest to help me get better clocks per voltage?

It looks like this for me (i5-3570k):

4.5 -- 1.205v
4.6 -- 1.255v (+0.05)
4.7 -- 1.305v (+0.05)
4.8 -- 1.365v (+0.06)
4.9 -- 1.435v (+0.07)

No idea about 5.0ghz as I'm scared about voltage.

ROFL! If I was really concerned with hitting a high OC for some reason... I would have just sold this chip and tried another one. If I can get 4.7GHz stable with under 1.46V I'll run that all day long and not even remember I wanted to see 5GHz. biggrin.gif

I don't know what to change with VTT and PLL, well how much to change it.

I wouldn't be scared about voltage - if your temps are good I'd go ~1.52v without worrying at all. Sure your chip might not last 10 years... but will you care if it only makes it 5? And even then it won't die - just likely start requiring 1.5v to hit 4.9... then later to hit 4.8v. smile.gif

In any case, unless you're still running a Pentium III somewhere around your house - you'll be running something else long before the voltages get you on that chip... IMO at least. biggrin.gif

The VCore jump is exponential on the Ivy series atleast, I was stable at 4.6GHz with only 1.2V :l

Requires 1.49V for 5GHz.
