CPU i7-3930K S-Spec: SR0KY Stepping C2
So after more tests I found out that when I disabled VT-d and Intel Acceleration Technology the random freeze disappeared.
In the past months I tried disabling Intel Acceleration Technology alone once but it didn't fix anything. I didn't try mantaining just that enabled, just to be sure I disabled it along with VT-d because both are related to direct I/O hardware access and acceleration functions at CPU and chipset level.
The system is not freezing anymore under Win7-x64 SP1.
I am going to report the bug to Gigabyte GGTS too in reply to their last quite rude answer in which they were negating the issue and claiming it was my fault, refusing to update the X79-UP4 Beta Bios to the latest Intel Microcode, Intel Management Engine Firmware, Intel Gigabit Firmware and RST option rom versions.
With the Microcode stuck at 70B while Intel released 70C,70D,70E an 710 to OEMs but Gigabyte never gave any to its customers... it's highly likely that the freezing bug it's a documented issue with either CPU Microcode, Intel ME Firmware or both.
I don't know if the bug could be due to the Hauppauge HVR-3000 TV tuner PCI card or the Intel NIC PCI-E card or the AMD PCI-E GPU and/or the Adaptec 5805 RAID PCI-E controller card.
What is for sure is that it shouldn't happen whatever the cards installed in the system are. VT-d and Intel Acceleration Technology must just work with no random freezing. Period.
Intel is not telling that those technologies don't work with some cards.
It's a critical bug that Gigabyte must fix and it's preventing customers from using Intel CPU functions properly. Now I am going to report everything to Intel too. I didn't do that before trying to figure it out and now that I found what is causing the random freeze bug I can tell them. And I will tell them that Gigabyte as an OEM is not giving its customers the updates Intel releases, so preventing Intel customers to use CPU and chipset technologies.
