Does anyone else have this issue? I know of one guy with a Opty 180 who has also confirmed this getting core 1 54deg, core 2 66deg. This happens with my stock heatsink and current cooler. I even reseated the heatsink to get the exact same result. Looks like I'm not the only one with this issue with a X2 4800+ Toledo http://www.tomshardware.com/forum/246095-28-core-core BTW:-I get 62deg & 50 deg on one core with stock speeds on the stock cooler in Orthos.
