Using an Asus P8Z77 V Pro and 3770k chip, getting 4.5mhz @ 1.330 volts. Just looking around on the web, it looks like many people hit that speed with much less than 1.3 volts. I know each system/part is different, but mine seems so power hungry. I'd like to push the system to at least 4.7 but can only imagine that would happen if the voltage was pushed to 1.4 or so. Prime seems stable and temps are in the low 60's. Are my voltage settings too high?

 

Thanks!!

Is that full load Vcore?

It's of course your call, but do realize when you push volts to the bleeding edge (of instability) bang for buck goes precipitously down. 4.5 to 4.7Ghz is a whopping 4% increase in clockspeed and will add little to none in the way of significant difference other than for bragging rights. Moreover, over-volting will likely lead to deteriorated functioning and early failure (please note, I did not say WHEN it will fail, only that it will likely fail before it would have otherwise if run at stock voltage). I had an expensive Extreme Edition processor do this, so I speak from experience. And I was always within the 'absolute maximum' vCore from the data sheet, and not for very long periods either. Also, be aware future CPUs may be hard soldered to the mainboard so replacing them will be not so easy, so you may want to consider this when stressing your parts. It's possible we are moving away from the era in desktop parts where enthusiasts can easily play, though folks manage to find ways where there's a will ;o)

Sounds about right for 4.5. I'm currently at 1.44vcc for 4.9 on an MSI mPower. Temps in the 60's under load.

It's ok, just watch the temps when CPU is under load. I think you can go higher without problems. Try to run IBT test, the limit is to stay under 90c with IBT(orientative and quick stress test) - under 90c in IBT means safe temps with other stress test and more than safe with fsx

Yes, it's under full load. As Noel pointed out, for the minimal return on bumping 4.5 to .7, I'll be leaving the overclock at 4.5. I'm probably the last guy who wants to push the cpu to obvilion at this point (see my other thread under delidding gone wrong). I might also add that I'll be investing the $25.00 to get the Intel overclock replacement plan
