xI have the following configuration since Dec. 2009:
Motherboard: Intel DX58SO with BIOS SOX5810J.86A.4196.2009.0715.*
CPU: Intel i7-920 (2.67GHz) no overclocking
RAM: 3x OCZ3P1333LV2G DDR3 1333 (total 6GB)
OS: Windows 7 Ultimate 64-bits
Video: nVidia GeForce GTX285 (1GB memory) on PCIe x16 slot
Hard Disks: 2x Western Digital 1TB each (internal) + 1x 750 GB Hitachy (eSATA)
Optical Drives: 2x ATAPI DVD Rewritters
Fans: CPU + Video card fan + Case fans (aux, rear, side, bottom)
PSU: Cooler Master 620W
Every now and then It gave me a BIOS boot warning indicating it failed to boot but not often. After 1+ year of operations (originally had Vista Home Premium x64 upgraded to Win 7 Home Premium x64) it started giving sudden BSODs. After a few months with the problem I decided it was time for a fresh start so I reformatted my drives and did a fresh install of Windows 7 Ultimate 64-bits plus all its updates.
Within a week of the fresh install (I am still migrating data) it started shutting down every now and then, a few times BSODs but other times simply a black screen followed by an auto-reboot. This got very annoying and I have been trying to solve the issue without much success.
I ran the MemTest86 (Linux version, tests all 6GB) several times and gave no errors. Once it gave errors all over the place but I believe that was some sort of glitch because I simply reset the test right away and let it run for hours without errors being reported.
Almost always during POST I see it shows the Marvell BIOS message "Adapter 1 Port 2" followed by the BA 94 BA POST code and then it goes black and then again the same procedure. In other words always does it twice.
Now that it is giving more problems I noticed that:
- Sometimes when I turn it on in the morning (first boot of the day) it keeps on cycling through the boot sequence without ever booting into Linux or Windows.
- A few times it got as far as loading Windows and then rebooting. Apparently if I leave it turned off but connected to mains for some 15 minutes or more without starting it, then it boots the system without problems and then works for hours (as many as 10) without issues.
- Sometimes it goes through the POST and at the end rather than booting Windows it stays brain dead with fans running at full speed. No video or hard disk activity.
I have been tempted to upgrade the BIOS from 4196 (2009) to 5599 (2012) but I don't see anything in the release notes that points specifically to a problem I have. Some resemble but are not quite the same.
I ran various utilities and here are their reports:
************** CPU-Z Suite (Latest) **************
- A triple memory channel where all 3 memory DIMMs are the same part number: OCZ3P1333LV2G
- All 3 DIMMs have exactly the same voltage: 1.350V (<-- Specs say 1.65V and MOBO BIOS set for 1.66V memory voltage)
- All 3 DIMMs have exactly the same operational settings
- tCL: 7 tRCD: 7 tRP: 7 tRAS 20 tRFC: 59 CR: 2T (<-- as suggested by manufacturer 7-7-7-20 @ 2T)
- Intel DX58SO chipset X58 rev 13
- Southbridge Intel 82801JR (ICH10R) rev 00
- LPCIO: NS PC8374L
- BIOS SOX5810J.86A.4196.2009.0715.1958 (15 July 2009)
- Graphics I/F PCI-Express x16
- CPU i7-920 Max TDP: 130W (is this the power consumption?)
- Core voltage: 0.879V
- Multiplier x12

I checked all over the BIOS settings and don't see any place where I can change the fan speed settings. Do note that the temperature on my room is usually 31 Celsius (I live in the tropics) even with a ceiling fan.
I would also like to know what is the wattage (power consumption) I can expect for this motherboard without CPU (CPU is about 130W) with those drives connected. Any suggestions as to what might be wrong with this? Having had many PCs over the years this is my first Intel motherboard and the only one that ever gave me problems. I am going desperate with this instability.
