woooow, nice setup there !!!!
the screen is from W2012 ? try to get intro BIOS and enable HYPERTHREADING there, it seems its disabled. send me precise motheboard ( server model number ) model and will search for the precise menu in BIOS......
w2012 should be capable of 160 cores. with W2008R2 im not sure........ and yes, it should be Win2012 dataserver edition.....
