The exact note on Tcase max http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/30417.pdf page 40: 1. Tcase max is the maximum case temperature specification which is a physical value in degrees Celsius. This value is programmed into Rev D and later processors. Refer to the AMD Functional Data Sheet, 940 Pin Package, order# 31412, and the THERMTRIP Status Register in the BIOS and Kernel Developer’s Guide for AMD Athlon™ 64 and AMD Opteron™ Processors, order# 26094. 2. Tcase max is programmed during device manufacturing with part-specific values for Rev E and later processors with 'Variable' indicated by the Case Temperature OPN character, and can be any valid Tcase max value in the range specified for the corresponding OPN. So AMD does program something into the device that indicates what Tcasemax is. This seems very odd to me, as it seems more like a binning parameter than an "FYI" type of parameter. I would still like to know how they expect go get more money for HE parts when somebody can just buy standard and sort for lowest Tcasemax numbers, and RMA the rest. --Alan
