Intel XTU will Stress Test my i7-4790k with no problems but causes a reboot within 2-4 seconds when I click on the "Benchmark" button. Prime95 causes the same problem.

[idata]

New build. Gigabyte GA-Z97X-UD5H-BK latest BIOS, F6, with all settings at "Auto" except for the CPU_OPT which is running my liquid cooler pump (Corsair H105).

16 gbytes of Kingston HyperX memory that will run memtest86 v5.01 for hours with no problems.

Build is running WIndows 8.1 Pro, and is stable except for the XTU Benchmark and Prime95 problem.

Downloaded and ran the latest 64 bit Intel Diagnostic Processor tool and everything passed with no problems. I've run the Stress test portion of the XTU for a half hour or so with no problems and core temps at about 60 degC.

But Prime95 and the Benchmark portion of the XTU cause a reboot within 2-4 seconds.

Anyone have a clue as to what I can tweak to make this go away?

Thanks

Hello Lfdal54, thanks for joining the processors community.

Please check the following document created by one of our Intel Engineers. /docs/DOC-23517 https://communities.intel.com/docs/DOC-23517

The following steps have solved the issue for a majority of customers. Try these steps before correcting BIOS settings:

• Update the BIOS to the most recent version for your motherboard.
• Verify that your thermal solution is correctly installed and working properly.
• Verify that your BIOS does not automatically implement an XMP profile for your installed RAM. Use of XMP profiles will increase the power needed by the processors memory controller.
