I have a Biostar TA790GX 128M mobo running a AMD Phenom 9600 (2.3gHz). I found a great deal on a Phenom II x4 830 and grabbed it. Upon checking out the bios info, it looks like I needed to update my bios to support a second generation chip (http://www.biostar.com.tw/app/en/mb/...n.php?S_ID=377). So I updated to the 78DEA525.BST bios and when it started up, my temp monitoring program read my Temp 1 (assuming my NB, you will see why later) as 92C idling, when before Temp 1 was no higher than 40C loaded. I flashed back to my backup and the temp went down.

Here is someone else's thread on this exact issue: http://www.techpowerup.com/forums/sh...ad.php?t=97812. Unfortunately no one commented on the post on what he did.

So obviously I want to install this new chip, but I am concerned on the temp reading. Is the temp reading correct (meaning is the BIOS sending too much voltage to the NB for real, or is it a shoddy reading)? Help please!

How are you measuring temps? Also, how are your CPU temps?

BTW, you link appears to be broken.

You may need to re-flash the BIOS. Before you do that. Reset the BIOS to default via the motherboard jumper or coin battery removal. Then re-flash the BIOS. Then reset the BIOS to default again (as previously done). Then restart the system and reset your desired config. Re-measure your temps.

Good luck!

I am using Speedfan to watch temps. The temperature in question I believe is the North Bridge because of this guy's post on another forum (http://www.techpowerup.com/forums/showthread.php?t=9781...). Hope that works this time.

Speedfan is saying my GPU and Core are all staying the same (65C for GPU and 30C for CPU), but "Temp 1" is going from 40C to 92C all while idling.

Edit: to be clear, my original BIOS that was preloaded with the mobo runs the NB at 40C, when I updated the BIOS so I could run a Phenom II the new idle temp is 90-92C (it does fluctuate). I reverted back to the original BIOS quickly, but I need to figure out what is going on so I can put in this new CPU.

I am hoping it is a bad read and that temp is not truly happening.

You didn't need to update the bios, the only reason you would need to update the bios is if you were getting one of the new FX chips. My Phenom II 955 was supported right off the bat on my Sabertooth but when i got my new CPU i had to update bios because current didnt have support for it

Under the TA790GX's BIOS tab (http://www.biostar.com.tw/app/en/mb/introduction.php?S_...) it specifically lists a BIOS update for Phenom II support. I am going from a Phenom to a Phenom II, it sure sounds to me like I need to update to this. What proof do you have Rockdm that I do not need to do this?
