I know that some of the older X58 boards don't support Gulftown CPUs without a bios flash.
For example my Bloodrage doesn't. The RIIIE is not one of the latest boards IIRC and whilst your CPU will fire and work not all of the cores will be seen ETC.
If you haven't already - flash the latest bios on there. The temp probes could be out of action due to CPU support not being fully implemented. Good news is if you do need to flash the bios then it should be nice an easy on account of it being an Asus. Simply get the bios, unrar/zip it, dump it on a memory stick and look for EZflash in your bios. It'll take you to an old skool screen where you simply browse for the bios and begin the process. From there it holds your hand, rewrites the rom, verifies it and then runs a checksum before letting you reboot to make sure everything is where it should be.
Quick check reveals -
Rampage III Extreme 1102 BIOS - 2010/11/09 update (9th Nov, backward American dates FTL)
Support new CPUs. Please refer to our website at:

And then when following that link you get -
Core i7 970(3.2G,Smart Cache:12M, rev.B1,130W) ALL Since Bios 0507
However, if you look more closely....
Core i7 960(3.2G,L2:4x256KB,L3:8M, rev.D0,130W) ALL Since Bios 0402
Soooooo, it would seem the 970 was added into bios 0507, which is a later bios that 0402, so see if you are running 0402 and you could have your fix right hyar.
