For 965 C3 users

[SubZero.it]

Please post you're 24/7 OC settings with this CPU.
Mine needs 1.400V for a mere 3.6Ghz, that's too high..no?

[TheBlueChanell]

My 965 C2 needed 1.4v for 3.8ghz stable which was actually undervolted. What are your temps looking like?

That seems extremely high for 3.6.

There is also here a whole thread about C3 cpus that can help you...

1.35 for 3.9 stable

[SubZero.it]

And it's not stable yet! Temperature tops at 51°C.But if you see in the bios I set 1.4125V and look what I get. Overvolts way too much



Gets 1.440V

[slaveondope]

I used 1.5v on the 955c3 for 4ghz daily crunching on a DFI and Biostar but only ~1.45v on an MSI (it lies)

[FlanK3r]

i have average chip, with 1.4V i have about 3800 MHz with aircooling in 32-bit system

Thanks, gave it a look.
1.35V and 3.9Ghz is what I was hoping. Gonna give it a try with this setting and with 1.5V 4.0Ghz. But not before having updated BIOS,maybe resolves the problem of voltage throttling,look with 1.4125v set:

Look at my sig

[SubZero.it]

Updated bios.
Tryed 4.0Ghz with 1.5V.Crashes
3.9Ghz with 1.35V.Crashes
3.7Ghz with 1.4V quick test stable.
Noticed that when the board tends to overvolt near to a 0.1V crashes,doesn't matter temperature that tops at a maximum 51°C.Writing asrock for getting a new bios that manages better voltage,needs it.Doesn't exist any modded bios for this board?

[FlanK3r]

with 1.4V maybe u can got about 3750-3800 MHz

[SubZero.it]

yes but 1.4V is the limit for my board with this throttling, and cpu needs more to squeeze it. So i'm gonna cross my fingers for a new bios, do that for me mates

[Nvidia256]

My 965 C3 @4Ghz+2800(FSB) 100% stable 24/7 @ 1.47V

[Tomasis]

prime95 stable 4ghz 1,44v 24/7

[Hey Zeus]

With my 955 C3 i needed 1.587v in the bios to achieve a stable 4.2Ghz.

[BeepBeep2]

Wow, I feel so humiliated by these results.

I need 1.31v for 3.4 Ghz stable, and I need 1.4v for 3710 stable. 1.466 gets me 3800, and 1.50v gives me 3900. I'm stable at 4010 @ 1.554v.


Yes, my 965BE C3 is THAT bad....and it's on a $325 water loop. Somehow I'm still able to squeeze 4.2 Ghz to bench with. Luckily my CPU_NB is strong and does 3 Ghz stable 24/7. *snickers*

[OC Maximus]

On Air: 3.8GHz @ 1.46 Vcore 100% Game Stable for 24/7 use

Under Water: 4GHz @ 1.52 Vcore 100% Game Stable and for 24/7 use (my current clock)

Benching Under Water: 4.2GHz @ 1.58 Vcore Stable enough to run through some benches but not 100% stable for 24/7 use

I need 1.31v for 3.4 Ghz stable, and I need 1.4v for 3710 stable. 1.466 gets me 3800, and 1.50v gives me 3900. I'm stable at 4010 @ 1.554v.

No yours isnt that bad some people how shall we say, have incomplete information

[Daveburt714]

And it's not stable yet! Temperature tops at 51°C. But if you see in the bios I set 1.4125V and look what I get. Overvolts way too much Gets 1.440V

SubZero.it: IIRC my 965 C3 ran best ~1.50v and that was good for ~4.1 stable (on water)...

Temps were the biggest hurdle and it always got squirrley around 53c on the cores.

Every chip is different, but for baseline testing, set your Vcore so that the OV doesn't take it much over 1.5v and keep an eye on temps, trying to keep load below 53c...

As for 1.4v being too much, it isn't, as long as you can keep temps under control.

[BeepBeep2]

Well I can get 4050 @ 1.62v load.

I just dont understand people with their 965BE C3's getting 4 Ghz stable at 1.44v (I can hardly grab a validation at that speed) and doing 4.1 Ghz to 4.2 Ghz stable with ease

My CPU just doesnt have it.

[Tomasis]

beepbeep, it is about luckiness and newer batch

i remember when i ordered a 955 c3, i saw that 965 could not oc so well at lower volts. Who knows if 965 oc better on LN2 due higher volt leakage

lets say one cpu sucks on air but is excelled on ln2 as chew says

sorry for destroying the thread with my 955

LOL...

At least my NB does 3100 benchable on water

this is good what volt? I didnt run nb much due crap cooler, tested to run 2600 at stock volt. once i get cogage arrow (or h70 if its good) a month later then i will give full speed for cpu & nb.


i think other users should post nb speeds & volts here for comparisons.

[FlanK3r]

yes, its about batches...first 0944 or 0942 was great C3 965 for OC, than was some whorse (average) batches, with 955 C3 and newest 965 C3 was good batches, think, most of 10xx batches are good. Know people form czehc forums and they are average 4 GHz with AIR and 1.488-1.5V, someone has 4120 MHz with aircooling and 1.55V stable. Lucky man....I have problem with more 3950 MHz

1.55v but I was running 3000 24/7 @ 1.50v CPU_NB

I'm on water though, on air I was running 2800 24/7 @ 1.35v

...but I needed 1.25v for 2600.
