Malo sam intenzivnije testirao licno, browsing forume itd... Zakljucak za sve koji zele 24/7 4Ghz overclock sa X6 na vazduhu- Tezi slucaj. Dobra voda required!!! Thuban ima jednostavno mnogo mali temp. wall i sve preko 55c je BSOD svakog sekunda. Megahalems i Noctua nh d14 jesu dobri cooleri. Moja nhd 14 hladi pod prime da cpu ne prelazi 58-60c, ali to je jednostavno nece vrsiti posao kada je Thuban u pitanju, jer on vec na 55c odbija poslusnost. Dzabe je Pedja bio glavu i nervirao se, a i ja takodje. Ako ima sta da hladi cpu na mid 40s vrh, ako nema, salili smo se...Nije stvar u nicijem znanju i neznanju, losim i dobrim primercima Cpu-a. Spustio sam na 3.9Ghz i to radi sada na smesnih 1.464v, c&q, ce1 on.... Sve preko, Prime vise od 2-3h jednostavno ne moze da izdrzi na ovoj sada vec povecanoj ambient temp. Kad temp. dodje do 53-54 na 4Ghz vec slobodno mozete sami da prekidate test da ne iznenadi restart. Trebao sam ranije malo da citam pa da jurim neku vodu, ali oh well, 300Mhz je u pitanju...a ivi je ipak silent resenje...
Noctua i Mega ovde ne vrse posao:
"Due to the special process of how an AMD CPU is made, the max temperature of an AMD Phenom II and Athlon II is 55C. If you want to know why, you should read the information above. Intel has a different process of making CPUs so in turn their max temperature is much different than AMD, but the difference that counts between the two is not max temperature but minimum temperature. With AMD’s special blend of silicon, the company has produced CPUs that have no Cold Bugs. Theoretically these CPUs could operate close to 0 Kelvin (absolute 0; in other terms, where atoms stop moving). While on the other hand Intel’s CPU can only operate at around -175C, but there are few that do not have a CB.
Anyway back on to topic. Why give you all this information? Why create a background instead of saying that NO MATTER WHAT the Phenom II and Athlon II will not increase in speed after reaching 55C on loaded temperatures. Let me repeat that, all Phenom IIs and Athlon IIs will not increase their speed (overclock) and more once the loaded temperature on the cores reaches 55C. The understanding is all explained above, but here is the summation. Due to high amount of energy produced by the CPU, and the special blend of silicon used by AMD, the CPU will not be able to operate any higher than 55C or it will literally start to get into a range of extreme temperatures that could cause the CPU to catch fire.
If you find yourself stuck at some point while trying to overclock your CPU, take a look at the temperature and see where you are at. If you are close to that 55C sweet spot, you have gone too far, and the only way to go faster, is to decrease the temperature of the CPU itself."
