I have a problem that I haven't been able to solve. I have a dell t7500, it has 2 6 core CPU's with hyper threading for a total of 24 cores. I installed a clean copy of win 8.1. things all looked good, so I installed a clean copy of Boinc 7.14.2 x64. when I started Boinc it was only using 12 cores. I then went and made sure that the hyper-threading was turned on, which it was. I then checked both the local and web based prefs. to make sure they were at use 100% of CPU's, they are both at 100%. I then looked at the device manager to see how many processors it was showing, it shows 24. but Boinc is only using 12. I have turned hyper-threading off and then Boinc only runs 6 wu's. I have not uninstalled Boinc and reinstalled it. I don't know what else to try so thought I would get advice from the pro's. thanks for any help
