Hi all,

I know it's been asked before but just wanna make sure if my volts are safe for my 3.6ghz oc'd q6600.

BIOS Volts are 1.5375 and real volts peak at 1.49. 100% Prime Temps are 53C using a True cooler. Idle temps are 23c-25c so temps seem fine.

Intel says 1.5v is max, but is it safe for long term use at 1.49v?
 
Well...

Aslong as you don't push the VTT voltage too far (I think beyond 1.4ish) the Q6600 seems to be pretty much bullet proof...

Anything over 1.5 is pushing it - but I don't know anyone who has managed to kill one yet from too much vcore - that includes people who have them running 1.65v 24x7 (using water cooling).
 
Voltage up to around 1.55v is "safe", 1.6v with some heavy duty cooling... you shouldn't have any issues running your VTT (FSB Termination Voltage) at 1.6v

Temps you should aim to keep under 75c on Prime 95 Small FFTs, by the looks of it you have some headroom on that overclock
 
Thanks for the responses. In my motherboard I only have options for +0.1, +.02, +0.3 etc etc for the FSB voltage (that's VTT volts right?). How do I know what it's running at? It's currently set to Normal as I have not altered it...

Do I only need to modify the vcore or should it be a combination of both? Little bit confused as I have since seen people mention the VTT voltage and have suggested playing around with it...?
 
That's a lot of volts for a q6600. Does it really need all of that to be stable at 3.6Ghz?

I only needed that much to be stable at 3.85Ghz and had to up it a lot to go from 3.6 to 3.85.

From memory, 3.6Ghz only needed 1.4v

But apart from that, your voltage of 1.49v will be fine as you seem to have adequate cooling.
 
I had to put 1.512 through mine at 3.8ghz, 1.4 for 3.6ghz, llc enabled in bios. load temps at 3.8 never went any higher than 68-68-62-62, cooled by a TRUE black and 2 x 2000 rpm fans.

The Q6600 have very varied overclocking ability - some of the early G0 chips would do 4gig on 1.4 :S some of the newer ones struggle to get anything over 3.0gig - on any voltage. Mine needs all of 1.5v to get 3.6gig stable.
 
It's unreasonable to assume that all G0's will overclock equally. I have overclocked some G0's easily to 3.6GHz accept my own, which is very annoying. The highest it will go (no pun intended) is 3.5GHz which is fine really. A +1GHz overclock is not to be sniffed at.
 
My 1.3250v VID G0 requires 1.38v to get to 3.0ghz, but 1.48v to get to 3.2ghz. Cant push any higher without breaking 1.5v :(
