Extremely unstable system
« on: 08-October-08, 02:10:02 »

Hi - hope someone can help.

MSI k9n neo-f v3, AMD Athlon 5400 X2, 2x Elixir 1GB DDR2 PC6400M 1.8V (dual channel)

Power on - sometimes the system boots and runs for 30 odd mins. then freezes. Sometimes boots and runs for a few minutes or even seconds before freezing, sometimes does not boot to BIOS, freezes whilest in BIOS. In short - it can freeze at anytime during the boot process.

Looks like overheating - supplied fan works fine, used a fan for Athlon 6000+ x2 - bigger but no difference.

When I have been able to access BIOS have noted that MINIMUM Voltage for memory is 1.9V!!  Specs say 1.8V though BIOS will not allow this value.  Specs. for Elixir Memory say they should run at 1.8V. Could this be the cause?

What VGA and PSU you use?{List PSU details, look over PSU sticker}
Do memory check with >>Memtest86<<, for details you can take a look here:

VGA - Nvidia GeForce 8500GT 256M TC SPDIF V/D/VO (PCIe)
PSU - CTK Switching Power Supply
         Model: LC-B500E
         AC-I/P:   115/230V~   10/5A    60/50/Hz
         DC:         +3.3V          +5V      +12V         -12V    +5VSB
         O/P:        28A            50A       18A           1A       2.5A
         -------------------------------------
         +5V & 3.3V combined load 230W
         +5V & 3.3V +12V combined load 422W
         Total output is 500W Max.
         -------------------------------------

Have 2 x CDs, floppy and SataII disk.  It's an oldish ATX box with 20 pin power connector, using this in the boards 24 pin power connector socket(aligned with pins 1, 13) plus the 12V 2x2-pin power connector for CPU.       

Will do the memory test - assuming the box will stay up long enough for me to do so.
Cheers.

Your issue is probably PSU related. The PSU listed above is a junk.

>>> PSU's---2 x 12v---The Dual Rail Myth <<<
>>> Is your problem caused by your PSU? <<<

Good PSU suggestions and more info: https://forum-en.msi.com/index.php?topic=112039.msg836246#msg836246
