AMD Phenom II 965 OC and Temps Question/Safe/not safe - Page 2

I have ran 965 C2 at 3.8ghz with 1.55v and CPU/NB at 1.4v for over 2 years without any problem. Remember not all cpu are made equal. That guy may have got a bad cpu for ocing.

EDIT
Saying
1)Anything above 1.5V will cause serious degradation(it's just takes a bit of a time)
3)Anything above 1.15V will cause serious degradation(seen 1.35V degradated cpu/nb in 3 months)
Is just fulse information.
Plus there are ppl here that runs 1.6v through the Phenom II on a 24/7 use and there are still running for years.

EDIT
Hell I put 1.7v through about 5 Phenom II for about 8 hours each and they are still running today without problems at stock speeds.

I actually tried mine a above 1.55v when I was testing OCs. I had to go up to 1.62 for a 4.0 clock on my 965BE, C2. the heat was bad though it went up to 63c stayed there for about 2hrs and then went up to 65c and stayed there for the rest of the time.

I took the safe route since I don't have a foreseeable upgrade and put mine down to 3.7 on stock volts.
I also didn't see any performance difference though so I didn't see the point using the extra power, Im wondering if I did something wrong because someone just told me they OC'd their Q6600 from 2.4 to 3.2 and went from 25 fps in bf3 64P up to 60 steady, Im pretty sure its BS but on the other hand it makes me wonder if my OC is done correctly because I OC'd .4 up and didn't even see 5 fps change.

Ive been considering trying to get a better OC once i get better thermal paste, the stuff I have now is an unknown age and it was on the cpu when I got it, and well it looks aged. lol

Remember ocing is a silicon lotto. Meaning you can get a bad cpu for ocing. AMD only guarantee that they say it will run at. Like Phenom II 965 C3 is guarantee to run at 3.4ghz (1.35-1.4v) and CPU/NB at 2000 (1.15-1.2v). This is way AMD makes a basic guilde on ocing from the test they have done. The quality of silicon can and will change.

oh yea I know, it just made me think there was some user error in my OC. tongue.gif

Fact:
Most c2 are HIGH LEAKAGE wchich means:
-Voltage tank (can take a lot of voltage without degradation)
-Runs cool at high volts
-scales better with volts
That's why they put so high volts in amd oc'ing guide. Also I won't recommend anyone running 1.55Vcore on deneb C3 without a proof that it won't degrade the cpu in extended period of time (1+ years) So proof.gif please.
He has a low leakage C3 wchich is better for oc'ing .Most of those can run ~4ghz at ~1.4Vcore. I still own my 965 C3 low leakage. 4.1ghz at 1.38V 24/7 stable.
