Getting to 4.0+ is a real challenge. The system might not even be stable at those speeds. I tried with my X2 555 BE an i only managed to get as high as 3.85 (with a crapy cooler). I did't want to mess with the cpu voltages, so i did't really get as high as i would have.

So how do i go past 4.2ghz and my max temp on load is 50c

k not knowing what u have your cpu voltage set on so dont know if this well help but i am running at 4.2 using the same motherboard and cpu first set your cpu freg to 2600 some say more but runs stable on mine at that setting to up your cpu voltage to 1.5 to 1.525 also set your cpu northbridge to 1.2 to 1.3 runs stable on my at 1.2 but not all cpus r the same to set your northbridge voltage the same as your cpu northbridge and setting your dram voltage to 1.8 to 1.9 helps stable the ram if u r running tight settings on your ram give that a try and let me know if it helps u out and good luck o forgot to say i am stable at 4.2 useing a zelman 9900 cpu cooler so u should have no trouble sense u r watter cooling the cpu

I wish I could! For some reason my prolimatech megahalems very very badly. Even at stock clocks the CPU (965 125w) is hitting 53C! That's even with dual 90cfm fans plus an additional 2 fans at the front and back of the case. So best case air cooling scenario and i'm getting seriously bad temps.

is 53c load or idle temps?

Those are load temps.

well I gotten it down to 47°C with lapping and reapplying the thermal paste. They still seem like high numbers...Using the Megahalems too!

I must have really lucked out with my processor, My Phonem II 965 BE was able to hit 4.0GHz at stock voltage, and with only 1.46 volts can hit 4.2GHz, but not as stable...

I'm still experimenting though, should be able to do additional with FSB and HT overclocking also, but haven't gotten to it yet...

Those are not high numbers, not for load temps. Generally speaking, 70c is a break point for the CPU, and anything above 62c is entering a danger zone. 47c on load is very healthy, and would never be of concern for myself, personally, but considering the capabilities of your cooler, I can see why you are concerned.

I know that the numbers themselves aren't that high but the fact that I have a megahalems outfitted with 2 90CFM fans and those numbers are that high...it just doesn't make sense.

Cable management is great, the case gets great airflow. Mostly from being a HAF 932 but still. Both my old TRUE 120 and watercooling setup worked very well when they were in this case.

Those number were from around 78°F room temp.
 
Yea well 78F and up is considered hot, well at least for me it does because this normally means that the case is exhausting hot air into the room and in-turn making it warmer as the time goes by.

Is 78F the normal ambient or are you using AC to keep the room at that temp?

ok so some interesting (yet not too surprising) information in.

Always update your BIOS before overclocking! It can do wonders!

Before I couldn't even get 3.9GHz @ 1.42V stable and 4GHz @ 1.43V ran for an hour using the AMD Overdrive stress tester.
