3770K @ 4.6Ghz @ 1.275v - 92C max temp after 24hrs of Prime95?

post #1 of 9
Thread Starter 
Good or bad? My board is ASUS P8Z77-V Pro. I set CPU Load Line to Auto, but the rest to extreme. Should I leave it on Auto or set it to something else? I know setting Load Line to Extreme causes some extreme voltage fluctuations!

I set CPU voltage to 1.275v, but CPU-Z and UEFI report 1.280-1.285 fluctuation. I guess that is why ASUS wins at OC? Just add some more to whatever is chosen, LOL?

I know that its best to keep my CPU under 85C, but should I try to push it to a point where it never reaches 102C or so to prevent throttling, but up the clocks? I am using CM Hyper 212 EVO for air cooling and Noctua NH-1 for a thermal compound. I was thinking of 1.3v max and try to bump this puppy to 4.8Ghz maybe? Although I did read that most 3770K do 4.4-4.6Ghz on air without de-lidding, which I will NOT do.

I disabled all fan Q-Controls, so they are all running at constant maximum. I also frequently blow out the dust from my PC using an air compressor I own.

lower ur clocks and get a better cooler

Time to calm down
4.4GHz or 4.2GHz on my 3770k seems to work best. Last time I tested temps, I was capping out at 65c on my 212 EVO but lowered it down to 4.2GHz for longevity sake, not the OCN way. Last time I tested temps however was last year, before all the dust build up and general wearing down of the fans... I'd give it a good 75-85c for 4.2GHz now (considering my 7970s went from 75c to 92c under full load over the year of dust build up).

Why? My old 3770K ran at 95C max at 1.290v @ 4.4Ghz for 2 years before I tried to de-lid it, which almost cooled it. I even saw a chart on these forums of people who OC their 3770K on air and many get even higher temps running at much higher voltages. So why lower clocks?

I am planning on getting something like Corsair i80, but I will be modding it for GTX 770 usage as the fan on it gets real loud. CM Hyper 212 EVO is not loud at all, even at its max spinning.

I disabled all fan Q-Controls, so they are all running at constant maximum.

I never actually tried lower voltage, lol, because my old 3770K needed that much to get any real OC out of it. This babe runs faster and cooler at the same time! I also have an air-compressor and dust my case at least once every 3 weeks, so that all temps run optimally. My motherboard is also new. From what I understood, my new 3770K is from later high-quality batches, purchased at Microcenter in Atlanta, GA for only $250!

When we say lower your clocks, we ultimately mean lower your voltage to decrease heat output to avoid damage.
If you don't mind the high temperatures, by all means go for it... Just that I myself prefer to shy away from heating up 3770k as it seems I've gotten a nice one (4.4GHz at 1.185v, stable... 4.2GHz at 1.113v... Can't believe stock voltage fluctuates around the 1.21v mark.)

OK, I lowered it down to 1.22v and it still does 4.6Ghz flawlessly, but max temp is now 80C! What should I set for Load-line calibration in BIOS settings?

I would say Medium / 50% but you may need to readjust your voltage and stress test again as altering the LLC will change the CPU voltage fluctuation.

I got LLC at 50% while voltage is set to 1.21v and max temps is about 77C! Much better than 92C! Thank you so much!
