Hi!
I am experiencing problems with a Xeon Phi 31s1p.
The motherboard is Asus P9X79WS (BIOS version 4802 - the most recent), the procesor is Intel I7 3820 @3.6GHz, the video card is Sapphire Radeon HD 7990 and the operating system is Windows 10.
The option for Xeon Phi is activated in the BIOS.
The MPSS version is 3.6.
The problem is the card shows up in Device Manager both as Coprocessor and as Virtual Ethernet Card but after about 10 minutes it disappears. Even worse, micctrl -s hangs even when it is still showing in the Device Manager. By hanging I mean there is no answer returned and a cursor _ is blinking. During all this time, the blue led of the coprocessor is blinking continuously and very fast
In order to make it reappear I need to turn off the computer and let it cool off for a while. The thermal and power behavior is this (using a thermal sensor from Zlaman ZM-MFC2 fan controller and its powe readings):
- when the PC is turned on after cooling off, the power goes around 300W and the temperature of the Xeon Phi is somewhere around 70 Celsius.
- when it disappears from the Device Manager, the power falls to 150W and the temperature of the Xeon Phi drops to 32 Celsius.
Even when the Xeon Phi is not visible anymore in the Device Manager, its blue led still continues to blink very fast.
I would be grateful for any suggestions.
Thanks!
