QUOTE(mozact89 @ Dec 22 2009, 01:01 AM) try to set as low vcore as u can... now, im having prime on 3.6ghz, with vocre 1.18v(on bios, but show 1.22v on cpuz).. dunno why.. low vcore, u can get low temp.. adjusting...~btw, on AMD platform, i think vcore below 1.5v is safe ... currently 1.2Xv on bios , 1.32v on cpuz.. |

QUOTE(mozact89 @ Dec 22 2009, 08:25 AM) i think this its because of my thermal paste.. the CM thermal paste include in 212+ box doesnt look like thermal paste.. haha.. soo keras.. maybe will use tx3 later. hmm..i think thermal paste not a main issue...but cooler the difference between best thermal paste and normal only about 2~3 celcius.. hyper 212+ not really a suitable cooler to tame overclocked i5/i7 |
