I had a similar problem after upgrading the bios on an AMD mobo to be able to take a Phenom 9500.

Kept getting screwy readings, so posted the problem on the N/C board. A fellow cruncher provided the answer & it was one i had forgotten, but now do it every time after a bios update...

...reset the cmos.

It has been my experience from flashing hundreds of motherboards that despite what you had before a BIOS upgrade can change everything. Recently I upgraded the BIOS on my Quad-OctoCore machine and my temps have also gone up, however so has my performance. You have noticed this same behavior and I belive is normal.

Because of the difference you might be able to reduce your voltage settings or in some cases you may need to make additional adjustments. This is the reason that manufacturers recommend that you not flash your bios if your system is running normally. In your case you have realized a need to perform this step to upgrade your system so it is quite proper.

There maybe other options to revert back to a previous generation of bios that will allow the support of whatever processor you have selected. Commonly there is a bit of a range between generations of cpu's - you could try one of the other bios's.

As was said here previously by DJStarfox, temp sensors may be off and a later correction may have have been realized and now you are seeing the outcome of this. This is a very common event across manufacturers as they rush to get new products out the door. Remember that every processor is different and nothing is static when it comes to the properties from one unit to the next.

For a socket 1366 Core i7, the motherboard's CPU temp should read about 5C lower than the on-die CPU coretemp. Very frequently, motherboard manufactures do not calibrate their temp sensor properly, so it's quite possible the BIOS update addressed this issue. (For example, my EVGA X58 mATX board reads the CPU exactly 15C lower than the on-die temp.) An advanced ACPI monitoring program, such as SpeedFan, can give you both of these readings. This will allow you to compare temperatures and verify if I'm correct in your case.

What happens sometimes with BIOS updates is that they either fix, or break temp readings. On my board, the base release had a bug where the chipset temp would jump by 20C when it got to 50 (48, 49, 70, 71, etc). A later update fixed that.

Then a friend of mine updated his BIOS on a completely different setup and his temps went down by 5C. Did some digging around and even called tech support about it and they said there was an error where the values from the sensors were mis-read and reported a few C higher than it actually was.

It's possible that one of these similar scenarios took place. Also, the built-in benchmarks for BOINC are not perfectly accurate. They are pretty close though. If you run the benchmarks twice, you'll get different readings, sometimes as much as 15% different. Depends on what else is going on with the system (even in the background with the OS itself), since the benchmarks only use one core.

Linux laptop:
record uptime: 1511d 20h 19m (ended due to the power brick giving-up)

I figured out what is going on. In Seti's CPU Benchmarks before the bois upgrade the Whetstones were 3664 and the Dhrystones were 11751. After the bios upgrade Whetstones is 3670 and Dhrystones are 12822. SO they must have done more then what the bios upgrade says they added.

Ok, as I have stated 2 times before, all the settings are 100% identical. It is NOT from a setting difference. The CPU voltage bump would have to have gone from 1.35 to 1.40 for that much of an increase and it isn't different. There is something else going on.

There is no need getting like that....obviously something is different possibly from not loading the defaults before flashing.

http://www.biosflash.com/e/bios-update-howto.htm

Don't update an overclocked Mainboard. Load the normal BIOS-Settings, called: "Load Bios Defaults" , "Load Setup Defaults" , or "Safe Settings".

I would try simply flashing your motherboard one more time with the optimal's set and see what happens? Sometime also the motherboard works everything a bit harder with different bios revisions. Sometimes it ups the default pll voltages etc for improved stability or differences in temperature calculation in the bios.

Others are reporting the same thing.

Maybe you have the auto CPU fan control enabled? ..maybe the fan turn now slower?

Some mobos have saving/stock/performance auto settings.
Maybe you have enabled the auto OC settings?

I load always the optimal settings after BIOS update (I read this somewhere in the manual of a mobo).

I always load the bios defaults BEFORE the flash. After the flash it should automatically revert to the stock optimal settings on most boards. As far as changing your temperature I would just check all the settings and make sure they are the same, especially any over clocking and voltage changes you have made.

I have a print out of all the settings before and after the bios upgrade and they are 100% identical.

I installed the bios 1102 for my Asus Rampage III Extreme motherboard from 1005 (so I could switch to an i7 980X or i7 990X in the future). Now, nothing changed other then the bios version for settings. The interesting part is now the CPU temps are running 10C hotter then with the 1005 bios. You would think I bumped the CPU voltage from 1.35v to 1.40 for the jumps I am getting but you would be wrong.
