i7 980x safe voltages?

post #1 of 7
Thread Starter 
Hi all,

I have a 3+ year old i7 980x @ 4.25Ghz (HT off) @ 1.35 volts cooled with a noctua nh-d14,

Prime95 stable.. max core temp 73C after a few hours (most other cores reach around 67C).

It has and continues to serve me extremely well... but I recently got a 7990 and have been benchmarking so want to reach higher clocks! biggrin.gif

What's the "maximum" acceptable voltage for 24/7 use? Intel says 1.375 but what's your take on it? I have seen these chips @ 4.6Ghz with 1.47v under water prime 95 stable so...

Considering I'm air cooling, what voltages would you recommend to reach 4.3 - 4.4 Ghz?

Thanks!

Around 1.37v would be the most safe 24/7 clock, but really these chips have no problem with 1.4v-1.45v if they are cooled properly.
When I had the 980x I used to run it at like 1.42v every day.

And for benching runs you can easily take it to 1.45v for sure. Most I put through mine under benching runs was 1.52v, this was done on watercooling though.

So basically if the temp is not to high, don't worry too much smile.gif

I'm not prime, ibt, or linx stable, but I pass 3d mark, unigine, and gaming benchies. the performance @4.8 is awesome, but requires 1.47 to 1.48v(it fluctuates). I've seen people push these voltages on 2011, so I imagine these 1366 tanks can handle up to 1.5v with proper cooling. biggest issues for me was that my board was getting REALLY HOT!!! NB and VREG were was spiking from 85 to around 90C. I was running 3 GTX480s before, so high NB temps might be associated with running multi gpu configurations. when I decided to upgrade my gpus, I knew I had to do something with my board cooling. X58 Classified has a beefy heat sink and that was struggling, so i'm not sure how well your Asus P6X58D will handle higher clocks. I had H110 push/pull running prior to water, and on my chip 1.42v was about the limit. full load I was hitting 75C+. at 1.47v I was damn near hitting 85C+ wheee.gif

Thanks for the info!

For sure, x58 north + south bridges get hot when oc'ing.

It's good to see another gulftown chip still going strong after all of these years thumb.gif

My mainboard is the p6x58d premium, and I remember reading reviews back then saying it has some of the best north and south bridge cooling on any board when overclocking. I'm glad I paid attention back then biggrin.gif

I run my i7 960 @ 4GHz (HT on) at 1.4v everyday, been so for about a year, haven't had any issues. X58 chips are a bit "tougher", in that they can tolerate 1.4v+ without LN2 cooling. I clocked it to 4.4GHz with 1.45v, but my H80i couldn't keep up with the temps :|

I wouldn't go more than 1.5v. I did 5GHz on my i5-750 at 1.55v on water and it survived. Temperatures never went above 75C tho.
For everyday use, <1.45v if temperature are good 60-70c range.
