Back in 2014 the Intel Processor Diagnostic Tool (IPDT) was not working for 2011-v3 CPUs but now in 2015 they released an update on 20th January and maybe also earlier this year. However i just want to let you know.
It’s finally working for 2011-v3 CPUs
When i started in September 2014 with my 2011-v3 RIG i did test a lot and sometimes you’d like to know if you already burned or damaged something on your chip due to overclocking. A Diagnostic Tool, made by the same people who produce our chips, is the best choice if you want to check your CPU for injuries.
