Hi,
I've been experimenting overclocking my X2 4400+ chip over the last week or so. It's been going pretty well (especially with help from the great forum article on here). But i'm concerned about heat and voltages that I need to keep both cores stable and happy. I'm using 2 instances of Prime95 (affinity set to each core separately) to decide whether the overclock is "stable" - although to be honest even though Prime95 may report "hardware errors" i'm not seeing issues with any other app but...
I'm using the ThermalRight XP-90C cooler (nice) and a Zalman 92mm fan (52cfm at 32db or similar).
So, the default settings for my 4400+ is:
11x multiplier, 1.35v, FSB 200Mhz, HTT multiplier x5
This was giving temps in the 30's when idle and 40's under load.
I upped to these settings first:
11x multiplier, 1.475v, FSB 220Mhz, HTT multiplier x4
I first tried 1.45v but Prime95 would report issues with the second core after about an hour or two of processing generally, so i guess the second core needs a little more voltage to stay stable!
This was giving temps in the 40's when idle and low 50's under load.
My next attempt was:
11x multiplier, 1.600v, FSB 240Mhz, HTT multiplier x4
It's crazy fast (equiv to a X2 5000+ if it existed!) but only stable at that high voltage! Also the temps were pushing 60C under load!
So my question is - is the 60C temp safe for this core (it's an Abit AV8 board - does that report temps close to correct as well...?) so is the 1.600v a good idea?
I'd rather not use a louder fan, at max load it's quite loud enough for me.
Is there a different way I can overclock to give similar perf but lower temps/voltage - e.g. use a different multiplier? I'm assuming it's the raising of the voltage that adds most to the heat output...
Thanks,
Kevin
