Prime95 uses wide variety of computations that people encounter in daily basis, and does it slowly. 8 to 12 hours is the minimum for Prime95.

No.....Its preference.

Some people OC their systems and play a game for a couple of others. Others only run a single pass of IBT, and some only run prime for 30-60 minutes. Which is all i ever do.

Core temp is the temperature that the processor itself is recording. While not accurate at idle, it is important and accurate under load. U download hwmonitor?

If you want a quick test just do IBT 10 to 20 runs. I don't consider playing a few game to be stable. I know a buddy of mine did that and later crashed in the middle of file transfer. Corrupted the poor drive.

DUDE, you're doing perfectly fine on the temperature end of things (35° Core temp). You still have another 26° of headroom. Fast forward here and set the multiplier to 22, and get your voltage to hit 1.38V under load. Run prime 95 Blend. If its not stable, then take it to 1.40 and stop if any of your core temps hit 61° +. It looks like you still have some of the power savings features turned on because your Min Voltage is 0.90V.

The key BIOS settings to adjust before proceeding with CPU Performance tuning:
· Disable AMD Turbo Core Technology (can also be disabled via AMD OverDrive utility)
· Disable APM (Application Power Management)
· Disable “Cool ‘n’ Quiet” –power saving item from the BIOS menu
· Disable “C1E” –item from the BIOS menu
· Disable “CPU Fan Control” –item from the BIOS menu (allows max cooling)
· Ensure that CPU NB, Memory or HT Link values are running at default stable values (NB 2200 HT 2600)

And close that Asus application. You only need prime, hwmonitor, and cpu-z

Your cores are at 32-35C thats great you still have heaps of room! Just don't go over 1.55V.

under full load I'm sitting at 1.33 volts and 47C and 4.4ghz(10min prime stable for now). Tried to go higher on the multiplier with more volts and it would just freeze 1 min in when running prime. I'm using the config 2advanced suggested for the ht and nb

Sounds like you have a really good chip there. Dont be afraid to give it more voltage. If you want to be conservative, or are scared, dont go higher than 1.44V under load. I've gone as high as 1.6V for 5.2Ghz. This of course was not done with any stress testing. I ran Cinebench at 5GHz with 1.6V.

Much better. What are you goals? Make small goals and check for full stability.

FYI, both intel and AMD's publised max temps lately have been case temps - meaning the outside part of the chip packaging, not the core itself. this is a temperature you'd have to measure via a thermocouple on the surface of the IHS, not with core temp.

Generally speaking, silicon starts to die/degrade quickly in the 90-100C range (and no, I'm not recommending you go anywhere near those numbers).
