3770K, is 4.5ghz at 1.28-1.3 volts pretty common?

post #1 of 8
Thread Starter 
I tried it at 2.275v but it needed 2.285v to be stable in everything, time will tell if it will need 1.3v.

I know that no two chips are the same but I was just wondering if this was around the average?

I would think so. How are you testing? Time does not tell, Prime 95 Does.

I've only ran prime95 or about an hour or so.
Temps stabilize around 80c on the hottest core and around 75c on the coolest core.

My PSU isn't getting the right venting in this case right now so I think there's some extra heat I'll be able to remove when I purchase new PSU soon.

I think that's pretty normal for 4.5, yes.

Should be close. Mine failed after 3 hours of Prime 95.

Ran prime for 7 hours last night while I was sleeping and I woke up to find it still plugging away.

Think we have a good OC 4.5 OC here.

Temps were again 80 on the hottest core and 75 on coolest core.

I also need 1.280v under load to be stable at 4.5GHz, been running at this for a few months now, rock solid, and load temps are fine too. One thing I do notice compared to my previous Q9550 (3.8GHz) is that coming off load, the core temps drop really fast which I like. Not sure if that's the cpu or my new cooler (beQuiet Dark Rock Pro 2), but I'm happy either way!

My 3570k does 4.8ghz stable at 1.3v biggrin.gif but wont go any higher regardless of voltage.

Better yet I got it through the intel EPP (employee purchase program) so it cost me $140.
