I recently purchased a DX58SO2 motherboard and I,m having boot issues. the problem is very specific and reproducible . It occurs in two different situations.
The computer is turned off for a period of 2 hours or more. (I'll call that a cold start) when the power button is pressed the motherboard powers on
runs for 2 seconds then powers off for 1 second ,then powers on again with no boot, all fans running and a 00 on the LED. I then press the Reset button
once and the board powers off for one second and powers on again and then boots. the computer seems to run very stable afterward with no other problems.
The computer goes into hibernate state and sits that way for 2 or more hours, I click the mouse and the board powers on but hangs with all fans running and
a 00 on the LED. I then press the Reset button (sometimes up to 3 times in this scenario) and the board powers off for one second and powers on again and then boots. also I would like to note that any application/s that were running at the time the computer went into its hibernate state were returned to the same
states they were in upon windows resuming, with no stability issues noticed.
This doesn't seem to be a simple turn the computer off and it won't boot back up problem. its time sensitive in some way.
My System Spec's:
Motherboard: Intel DX58SO2 (ofcourse) BIO's Updated using Express BIOS Update SOX5820J.86A.0765 and set to default
Processor: Intel i7 960
Ram: 6GB Corsair CMZ12GX3M3A1600C9 Vengeance PC12800 DDR3 RAM 3x 2048mb triple channel (listed as CORE i7 on the box it comes in)
GPU: EVGA Geforce GTX 460 2GB GDDR5 PCI-Express 2.0 (one card only, not running SLI at this time)
Hard Drive: Seagate ST3320418AS Barracuda Hard Drive 320GB 7200RPM SATA 3G 16MB cache (pluged into SATA port0)
DVD: Asus DRW-24B1ST 24X Internal DVD Burner (pluged into SATA port5)
PSU: Corsair TX950W Power Supply
Case: Cooler Master HAF 922
OS: Windows 7 pro 64Bit
Steps I've taken to try and resoulve this issue:
1. Unpluged SATA hard drive and DVD from motherboard and attempted boot.
2. Removed RAM and ran each stick indiviualy
3. From the BIO's I turned down the voltage on my RAM it was running by default at 1.5125v I turned it Down to 1.5v (per tech support suggestion)
this of course is the only change I have now made to the default BIO's settings.
None of these steps had any effect or helped in any way, the problem persists. I'd like to add that this was a painfull touble shooting session as I had to wait about two hours inbetween tests after successfull boots. to make sure I was reproducing the problem if it was going to occur again after a change.
It has been suggested to me by Tech support that I do not have compatible RAM . I was very supprized to hear this since the DX58SO2 supports the RAM type I purchased, but it turns out that my i7 960 CPU does not infact if you look at the specs none of the 15 Intel Processors listed as compatible with the DX58SO2 are spec'ed out for RAM over 1066mhz. I'm told that the Ram is handled by the CPU now and not the motherboard and that the the BIO's is forcing my 1600mhz ram to run at 1067mhz, which it is. it was suggested that this is the reason that my DX58SO2 is experiencing this boot issue and that if I continued to use this 1600Mhz RAM that I would probably start to experience other unpredicable side effects. I'm not particularly interested in over clocking, I chose the DX58SO2 because it seemed to have alot of potential for me to upgrade my system over time.
I'm was'nt realy So I'm biting the bullet and I have orderd 6GB of 1066mhz
