Hello!

I was wondering, when overclocking a cpu like the one in my sig, what would be the maximum temperature i should really stop overclocking at when uping the FSBs and VCORE and doing a full load stress test with Prime95 Small FFT??? Should i stop overclocking after my temps on both cores reach dead on 70C or could i go a bit further than that on full load without doing any saver damage???

Thanks for responding.
 
I`m currently testing 3.9GHz overclock with Prime95 Small FFT and my temps on both cores are at 73C after an hour and a half on full load. I had to give the cpu a lot of VCORE, not far from 1.5v just to get it stable. I could enable the load-line calibration bios option on my board to decrease the load vdroop and allow me to use a lower VCORE setting but some people on hardware forums and sites on the internet recommend not using this for some reason.

There are other options in the P5Q Deluxe boards bios like CPU PLL Voltage, FSB Termination Voltage and NB Voltage that`is said to stable out an overclock, allowing to use less VCORE but im not sure of the corect settings for these.

Its well worth trying lower vcore with changing motherboard settings. You haven't left them on auto I hope?
70C is the commonly accepted maximum. I'd be happy up to 75/80ish but most people wouldn't. I would not be happy putting nearly 1.5V through a core2duo, while no one I've seen has reported frying one with vcore, 1.5V would definitely make me nervous.

Cheers

I currently left those settings on auto because i'm not sure what they should be set on for my current hardware. Maybe someone with similar hardware could give me heads up on what settings could work for me.
 
1.5v is far too much for a 45nm core. Ideally less than 1.45v and preferably 1.4v should be the max. I killed my first E8500 with only 1.52v vcore!! Should'nt really leave voltage settings on auto either as a lot of boards will overvolt.
 
I personally don't like it above 60c

1.45v is my absolute limit for my QX9650, which is only for brief periods

I currently run it @ 420fsb x 10 with 1.41v
 
70-80 on a Core 2.

Regardless, if it gets too hot the CPU will throttle or shut the PC down anyway. This happened to me on the weekend when my water pump lost its molex and wasn't getting any power.

I think it's really important to think which cpu temperature what we are talking about.

Temperture shown on system
need to be below 80 - 90

Temperture directly measured
has got to be below 60
 
Yeah, I did the same with my Q6600. Was running a suicide run at 3.8ghz, when it just blacked out. I don't think it slowed down though, just everything went off. I thought I'd killed it. :D Waited a minute, then switched it back on (with default settings) and it was fine.
 
I might just do with my original overclock that was running four hours Small FFT Prime95 stable at 3.8GHz with cpu vcore increased to 1.36875v and load temperature of 68-69C on both cores.
 
Did the same with my e5200, wondered why temps where in the 80s idle, heatsink was redhot, then realised fan wasn't spinning not plugged it in.
This was after reseating, fired back up after a minute though.
 
I killed one of my Athlons like that while putting together a system for the old man from my old bits. It toasted good and proper and took the mobo with it. Expensive mistake at the time.
