Wow i think i am coming to a point where i have to let my brain rest a little. I feel totally stunned after 3 straight days of learning about overclocking ^_^

As someone suggested on the first page, i re-applied the thermal paste and added 3 120mm Thermaltake (not very good but still useful) fans, which lowered the temperatures for like 8-6c. It was stable on 3.8GHz 1.4v, NB 2200 1.1v, but then this morning i said what the hell and increased the multiplier to 20x 4GHz and tried to test it but after like 30 minutes i opened a website with a little flash in it and everything started to crash biggrin.gif first skype and prime95 then googletalk and i kind of figured it's not stable biggrin.gif So i did a restart and increased the voltage to 1.425 and now it's passing it's second hour in prime95, also temperature while doing test in prime95 varies from 48-50 sometimes 52 but very rarely (i guess that's because sometimes it doesn't stress every component fully at the same time).
Also i noticed in HWMonitor on my motherboard it reports i have 3 temperature sensors. First two sensors indicate temperatures of 30c and 45c while doing the prime95 test and correspond to the temperatures in my bios. But the third sensor reports temperature of 81c. The thing that scares me is that sometimes this temperature is 80c. There is no such sensor reported in my bios, and after changing all these clocks and voltage it doesn't change it's temperature. Also this temperature was always present ever since i bought this motherboard and that is like 1 and a half year ago and then i didn't overclock anything, everything was on its default clocks and voltages. Now thinking logically i don't understand if this temperature accurate how could it endure such high temperature for so long. The one other thing that comforts me is that my friend also has a sensor that displays -147c but then again it's a different motherboard.
Also about adding those 3 fans, 2 of them are intake, one from the front of the case one on the side and the last one is the top/back outake fan. thumb.gif

Good so far. You'll be in good shape from reading the guides and taking your time.

I've noticed with Phenoms that 3.8 is usually had with fairly low VCore, but from there to 4.0GHz the voltage ramps up considerably to get things stable. Then to enable Cool-n-Quiet took more tuning, for me at least since the boards I've used disable CnQ after 18X and up. If you don't care about CnQ, that won't matter. If I ran the B55 w/out CnQ I'd have a 20X multiple, 200FSB and lower voltages.

Yea, someone already mentioned lowering the voltages but i didn't know that earlier... But it's good to know now:) Also i disabled CnQ long time ago, i can't remember the reason but i think i was annoyed by the changed noise levels 955 BE stock cooler has :S I just couldn't live with it. NH-D14 is pretty quiet by my taste so i don't know, maybe I'll try and play with it a little later when i get the better understanding how everything works.

EDIT: I just remembered after i wrote this that CnQ doesn't have much to do with cooling it's just that when it ramps up the frequency cpu gets hotter and that stock cooler had to increase rpm as a consequence. I always associate this Quiet with my terrible experience with 955 stock cooler. But of course if i enable it, it would make my cpu not work all the time on 4 unnecessarily, especially because i tend to leave it idle for long times. Totally forgot about CnQ thanks for reminding me smile.gif

50c does sound high considering you have a dh 14 , my 955 is reaching 50c max temp at 4 ghz with a hyper 212+ so i would make sure you installed it properly , and have good case airflow . but those temps are safe MAX temps are 62c
leave the fsb at stock and use the multiplier , but make sure you overclock the northbridge as well
i would be very careful overclocking a with budget motherboard it likely cant handle alot of voltage

I have the CM 212+ with a 4Ghz OC, how are you gettign 50c max temp?

what type of case do you have? fans? id love to push mine further tongue.gif
