I have an Intel DX58SO2 board with an i7 960 processor in a Win7-64 PC I built in April of 2011. I still have the BIOS 779 installed, since I did not have any issues I could see related to that version and I read too many posts here about bricking systems on the DX58SO2 boards. I had originally installed the Intel Extreme Tuning Utility, the Intel Desktop Utilities and other items from the CD that came with the board. All have been kept updated.
In the Windows Action Center, it has shown that the PerfTuneService of the XTU has stopped working very soon after every reboot. The only thing I used the XTU for was to change the fan profiles in the BIOS to ramp up quicker.
Initially I had 6 sticks of 2GB (12GB total) of Corsair memory in the system. I was unable to use any of the XMP profiles as it said they were not a match (all sticks had some part number and manufacture dates) and had it at the standard 1066 speed with the 1.5 voltage. This setup tended to get a high IOH temp in the 50s C, during normal use (reason for faster fan rampups). I did not do any other overclocking.
I then bought three 4GB sticks of 12GB of Kingston memory PC3-12800 DDR3 SDRAM UDIMM, as I had read that filling all the slots could be part of the higher IOH temps. One the Kingston was installed, I was able to set the XMP profiles at XMP 1600, which gave a voltage of 1.65. The IOH temp was lower even with the 1600 speed never getting over 56C even during hard gaming and video conversions.
Later after a series of freezes, usually in IE9, that first locked the keyboard and then the mouse, and finally the PC, requiring a hard reboot (but never gave any log or error dump), I took the memory down to 1066. The freezes became less frequent, but continued intermittently. I now believe that the freezes were actually Adobe Flash related as all my other IE9 ‘stopped working’ errors were Flash related.
After a reset reboot, I would get the Windows was not shut down down properly warning, but the keyboard was not usable. If I had done a hard reboot using the on/off switch, the keyboard was usable.
Is there any problem removing XTU? Since the original was installed at the first configuration and the version has not changed, would reinstallation be a good option to see if the 'stopped working' error persists?
As there is now a BIOS 0888 which based on posting (or lack of) seems to update OK, does updating to that version seem advisable for any of the issues posted here? I have had no USB issues except after the reset reboot on the freezes. My last BIOS update, (at build completion) was using the Windows updater with the OS and all the peripherals in the system and was flawless.
