Is my 1.35V too high for i7 950 4GHz OC? - Page 2

post #11 of 27
hmmm, you got a nice cooler there, I'm able to pull that voltage @ 4.2 with HT.

Most run 4Ghz at ~1.3v. Good chips are 1.2-1.25v. I get it around 1.25v. Do you have LLC on full? That and you may want to put ram on auto.


I also hit 4.2Ghz w/ HT at 1.31v. So not the best comparison. Good luck man.

Up that multiplier. Try a multi of 23 instead of 21.

Just dropped my v to 1.325 and she passed IBT, gonna try for 1.315 and hopefully get to 1.300.

Op any updates for your oc?

will try all your suggestions today after work, thank you for sharing. I do think though that 1.35V is high because it might damage the chip over time, planning to use it for a few years, thinking 5 but will see.

I had my old Barton XP overclocked but then it started to fail so I had to down clock it, ie put back everything to default settings in bios.

(http://en.wikipedia.org/wiki/Electromigration) Here is why I don't like to use higher voltage than stock which I believe is about 1.25 (correct me if I am wrong) . I saw some where on other forums that upping the volts will cause electron migration faster. But maybe I am being too paranoid about it. Let me know your thoughts. Maybe someone is better in the know. Anyone seen a thread about this in here before?

1.35v is perfectly fine for 24/7 use. Most people try to stay under 1.375v and 80 degrees C for 24/7. You probably will take some life off the chip by OC'ing, but it'll still last for years without issue.

1.35v is fine. If you are under water 1.4-1.45v would be just fine. At least for those of us that plan on replacing the chip within the next 10 years.

does changing multiplier to 23 from 21 help you in anyway?

as long as you adjust the fsb accordingly. ie: my system runs on 21x200 = 4200 or 23x183 = ~4200. My ram tends to like a 200mhz fsb.

try 20x200 and 1.300v, I'm currently running that voltage @ 4.2

my 870 needs 1.42v for 4224mhz .. had it like this for 7 months .. works perfectly .

aslong as you have decent cooling , dont worry . If something was gonna happen , it would of by now .
