c2 740 unlocked

post #1 of 5
Thread Starter 
Do c2 chips run really hot compared to c3 chips?
With my a70 push pull set up i can top out at 60c in linx with 1.55vcore and 1.45v nb


Does this sound about right?

With my 740 unlocked and a Coolmaster N520 (92mm) cpu cooler I get close to 60 prime at about 1.43 vcore around 3.5 ghz. Never could get it stable at 3.6 no matter the voltage without considering temps. Most of the time run unlocked it around 3.2 with 1.31 vcore and cool n quiet on for the Florida summer. Also depends on the quality of your chip though.

Yea the 720 30 and 40 are notorious for being a beotch and a half for achieving high OC's...but yea a C2 chip has a higher TDP so more watts = more heat....60c is not catastrophic....but i'm sure someone will soon come here and say "no no no keep it below 55c" Honestly once it works for you go with it...my buddy had a C2 945 at 80c for like a few weeks and did not recognize it...chip still runs fine today.

They usually require higher voltage and thus they run hotter
post #5 of 5
and a 64bit os isnt as oc friendly as 32bit.
i can overclock higher on win7 32bit with less voltage than on 64bit.
