The BL460c can slot a couple 50xx models, but I don't know if the machine's chipset implements HTT support. Intel's web site details the chips by model.<BR /><BR /><A href="http://www.intel.com/products/processor_number/chart/xeon.htm" target="_blank">http://www.intel.com/products/processor_number/chart/xeon.htm</A><BR /> Fri, 15 Jun 2007 14:06:10 GMT Heironimus 2007-06-15T14:06:10Z https://community.hpe.com/t5/bladesystem-general/hyperthreading-in-bladeserver/m-p/4021114#M669 Does the BladeServer BL460c or BL685c support hyperthreading, if yes where can it be turned off.<BR /><BR />Thanks,<BR />topokin Fri, 15 Jun 2007 11:38:06 GMT https://community.hpe.com/t5/bladesystem-general/hyperthreading-in-bladeserver/m-p/4021114#M669 topokin 2007-06-15T11:38:06Z https://community.hpe.com/t5/bladesystem-general/hyperthreading-in-bladeserver/m-p/4021115#M670 BL685c uses AMD Opteron processors which never have had HyperThreading. <BR /><BR />BL460c features Intel Xeon 5000 series processors which are dual or quad core and do not have HyperThreading.
