10 . All hardware in the nominal mode .
11. Computer runs completely stable, since my build at the end of December 2013 .
12.Problem- Wanted to reduce the CPU temperature by reducing the Vcore.
In my case standard value- Vcore Base -1.041v. Vcore with Turbobust - 4core * 3.4GHZ-1.093v and 3.6ghz single-threaded load the core at a voltage of 1.150v
In the BIOS set the offset (Offset)-0.1v to the base voltage in manual mode , all is well , the temperature dropped by 5-7 degrees , but testing and return to auto setting in bios , sensor core voltage not be restored -same base vcore 0.941, 0.993 in turbo- still, in manual mode when i am fixed default voltage and restart - result is the same no back to 1.041-1093.
ALL power saving cpu technology on. i did all combinations-tuning-auto-enable-disable them. But result same.
Only helps complete shutdown, with standby power off for half a minute , sensors Restores , I thought Me region fail .
Made a backup BIOS entirely through FPT (Flash programing tool from intel)did full dump -fptw64-d bios.bin, did fully rewrite F6 version - fpt64-f Z87D3HP.F6-SAVEMAC. ,Next full Power off waited a minute to restart Me frimware, turned on , dropped to the factory defaults , again reproduced the problem. As a result, returned to backup bios.
Please clarify what the problem is , bios bug or my " hands " , something else.
if it is a bug, please who has a direct link with the gigabyte's specialists
please let them know.
with best regards Vladimir.
