V1.00 (with no Dual Core support). The system was running with V2.01 for over 2 months with no problems. >> V3.01 >> . Adjusted CPU temperature readings > > Yeah- it's now on my to-do list.

Hopefully the numbers will be significantly lower w/updated BIOS. The BIOS update doesn't make the CPUs run any cooler. Just the temperature readings will be adjusted. The output of the internal thermal diode on-die varies. Therefor you (or the BIOS programmer) should recalibrate the temperature readings by adding or substracting a diode offset. http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/26094.PDF Section 3.6.19 Daniel
