Just stick with the core temp.
Or u can try update to latest bios which corected temperature sensor issue.

Its normal to have temperature around 46c for each core when at full load.

33c is seem too good to me.
For my case, idle with stock heatsink would give me 39/40

as long u din raise your vcore too much while overclocking, ur temperature will be around 50c or below 50c.

That's why performance heatsink comes in especially when overclocking.

I'm also using x2 3600+ and tf550 like u.
idle 39/40c, full load 46/47c, Othos priming can reach almost 50c. Btw, I'm only running at 2.2ghz 1.2vcore.

p/s : Please accept that stock heatsink isn't that great, u can't expect miracle from it. Coretemp should give u exact value, don't cheat yourself with the lower temperature from those monitoring software unless you feel better with it.

you have too many things running in the background, plus slow RAM.... which explains 38secs in Pi 1M.

Try experiment with Trfc values... if 127.5ns cannot use, try lower one. Use the BIOS built-in memtest to test.

Who says cannot? Come on la.... I have used TF550 before. I say can lock, can lah. Probably you did not disable spread spectrum thingy.

p/s: the automatic overclock option is lame... don't use it.

Can la. I post up this issue before. Always get stuck at 273Mhz. Any timing also dont help.
Then i flash bios703 as recommended by Soulfly. Now running at 345htt day and night. And comfirm it lock now as reported by my Clockgen. 
Go download bios 703 or higher. From some taiwan biostar web.
Biostar 6100 Am2 is crappy because it dont have adjustable memory setting for Cas Latency. That make really give us headache as it gonna fix CL at 3.0 even at DDR667. 

in ur bios options
juz set it to disable laa 

Did you ever read the post that I replied you? 

Even if you set automatic OC, the bios already bump up the Vcore; it was just that cpu-z display it wrongly..

You could keep on increase the cpu clock or prime it for at least 8 hours for stability check...

luckyghost, go to bios set vcore to 1.2v, push ur HTT up gradually from 220 and prime it min 8 hours(use Orthos) for stability.

Max out what u can do at stock vcore.

High clockspeed need higher voltage is normal.
Some can do near 2.4ghz with 1.2vcore...anything more than 2.4ghz, u need to pump a lot.
So 2.5ghz at 1.4v? normal.
Go try urself instead of putting auto voltage. Go try 1.3v, 1.35v
