Re: Problems with more than 8 AMD Opteron Cores per System

Ensure your BIOS supports the stepping of the Opterons you have. Eg, if you have the Iwill H8501, BIOS v1.8 [1] covers all the current steppings. You may even encounter problems if you mix different steppings. --- [1] http://www.iwill.net/product_2s.asp?p_id=90&tp=BIOS Oliver Weihe wrote: > Hell
