Supermicro X10DRD BIOS is up to date? BIOS defaults set after BIOS upgrade?
Thank you for your good suggestion.
But after BIAS upgrage, my PC still has E5-2690 CPU running at the highest frequency of 2.6Ghz.
The CentOS OS version is 6.5 and the motherboard is supermicro's X10DAi-O.
Is there any way to solve the problem that the turbo Boost frequency suggested by the spec can not be used?
I look forward to the advice of my great advisers.
