How much variation in Chip temperature is "normal"?

:)When using my Asus KGPE-D16 board with 6128 chips the CPU 1 & CPU 2 temperatures were a few degrees C apart with the CPU 1 temperature always warmer. Temperatures were 31 CPU 1 and 29 CPU 2. I know, I live in a cool climate. When I installed 6174's the delta T rose to 10 degrees C with CPU 1 39 and CPU 2 29. system was running same WU, Kraken was running and Dynamic load balance working. Less that 1 degree difference between heat sink of 212 and CPU case as measured with scanner. The TPF decreased from 6:10 to 4:09.
Kill A Watt went from 265 to 293. I would like to understand if this is "Normal" or not.
Best regards, Charlie
 
With my 6128s and 6166HE, the widest range of temps is about 3 degrees. I have only seen 10 degree temp differences with Xeon CPUs.
 
A few degrees difference is no problem. If you see large differences I would check fans/air flow, and possibly re-seat the HSF. If problems persist after those procedures, it could be a faulty thermal sensor. It seems to be more of an issue with Intel CPU's than AMD CPU's.
 
10C isn't much. if it was a 20-30C difference then yeah more then likely the heatsink isn't mounted correctly. but 10C can be as much as one cpu having more thermal grease on it then the other or one running at a slightly higher voltage then the other.
 
Thanks for the information, I was beginning to think I might of had a bad chip. Since I have never been aware of what a bad chip would be , partial failure or they just don't work? Even though since changing from the pair of 6128's to 6174's the WU time was reduced accordingly and is also in line with the 4P 6128's on the same 8101. Best regards, Charlie
 
Having this exact same sort of behavior on my KGPE-D16 as well, but with AMD 6274 (2x). One chip always runs about 10C hotter than the other. I've tried MULTIPLE KGPE-D16 boards, and it always reproduces. Tried swapping the chips as well, so it wasn't a chip issue.

Please see Sirmonkey1985 post #4 above.

Sometimes it spikes more than 10C though is the weird thing. I've had it be CPU1 at around 48ish, with CPU2 at 29ish.

I know it's not the CPUs, or the heat sinks -- because I've swaped the CPUs, and the heat sinks (heat sinks first, then CPUs, just to be sure).

I've also replaced the motherboard with an RMA and it still happens exactly the same with the RMA.

EDIT:

After speaking with ASUS on the phone about this issue, they are going to investigate whether this is a BIOS issue or not since they believe I have narrowed down most, if not all, of the hardware possibilities on my end. If I have any new info on a BIOS fix for this I will post it here.

Nice bit of troubleshooting Eudiphon. Hopefully something good comes of it.
