Core temps seem low under load Xeon E5440

Just make sure you go through the procedure of updating/installing the new BIOS correct and that the BIOS has good reviews (comes from a reputable website) and you should be fine. If you are worried about it and the setup you have now seems to be working fine then I would say just leave it :)

Okay, thank you!  :)  :)

Hello everyone,

 

I recently purchased an Intel Xeon E5440 (socket 771) for my ASRock G41C-VS (socket 775) motherboard. I have this ----> http://www.lc-power.com/en/product/power-supplies/lc-cc-95/ cooler sitting on it. My problem is that when it's under load only the first core's temp rises significantly, and then the others rise by 4-5 °C. On idle the CPU package temp sits around 32-36 degrees celsius, the 1. core is around 36 °C, the 2. core is around 28°C, the 3. core is around 28 too, and the fourth core is around 16-20°C (!!). I think this is very strange. It passed Intel's diagnostic software, it passed linx, so I don't know. Maybe the cpu's temperature sensor is broken? I attach a picture of my 100% load temps. Please help me, I'm very confused, this drives me crazy.  :unsure:

forgive me if im wrong, but think xeon chips are cooler than consumer i5 i7s since they are designed for server use.

67c safe operating temperature for that CPU, so I would try and stay below 65c. I do know the LGA 771 Xeons have a higher safe operating temperature than their consumer counterpart so if you keep it below 67c you should be more than fine.

As for the weird temperature reading I would say it is probely due to the socket mod (not that you did anything wrong) but the BIOS might not be able to read the accurate temperatures. Also those temperatures seem fine for that cooler you have.

Thank you! Maybe, I should try installing a modded BIOS that has this cpu's microcode?

If you can and are willing to take the risk I say go for it :D

Can it damage my motherboard? I know, if something goes wrong, I brick my mobo, but if I succes, will it damage it?  :)
