What realy astonished me is that having an usb-memory stick plugged in results in ~6°C higher core and cpu temps in idle (not under load).
I don't remeber if i tried 130 bios in the past. However I tried the 9850BE in the M3A with the latest bios.
At 2.8GHz(cpu)/2.2GHz(nb) 1.325V/1.3V cpu temp was around 55°C after a few minutes of prime95. I had the window opened at those testings.
If I open the windows today i get a modes cold airflow over the board (not in a case atm) and the cpu temps drop to ~55°C also.
On the M3A i used the silicon thermal component coming with the xigmatec cooler on the DFI used AS5.
So based on these results the high cpu temps i get depend more on the cpu than on the board here, I'd need an other 9850e to double check this.
While I tested the M3A I had removed the heatpipes from the booard and applied AS5. It did not help with chipset and pwm temps.
I'm testing in ganged mode atm. With the 9600BE all my testings ran equal stability wise with ganged and unganged mode. I plan to try unganged mode once i found the lowest possible voltages (cpu,nb,mem) for ganged to see if it's the same. After that i'll try to find the lowest nb voltage required for 1.8/2.2 and 2.4GHz at 2.8GHz cpu frequency.
Next i'll lower the cpu voltage to 2.7GHz and test if i can get a stable system with lower nb ferquencies.
I also plan to check nb voltages at 2.8GHz with mem in 800 mode.
During my initial testings with the 9850 i found that the nb (at 2.2Ghz( required alot more volts to be stable at 2.9Ghz then on 2.8Ghz. That is an somewhat odd result. Getting 2.9GHz stable is a difficult thing with my cpu so i'll inspect these nb/mem/voltage issues in the save below 2.8GHz area.
Another note, in the M3A prime95 always failed on the thired core when i tried to get 3GHz stable. I disabled core three and four, the board has a bios option for that and voila 3Ghz cpu and 2.2Ghz nb ran stable at 1.35/1.3V. All four cores where not even stable at 1.525V. I guess it's mainly still a lottery thing how far the cpu can oc.
EDIT: I'll add my lowest voltage finds for nb and mem to my previous post to keep the results together.




I really wish that D.F.I would quit this Tom Foolery with this fluctuating temperature read out with Bios Release
. 1.25V vs 1.35V is quite a significant change.
