More A8N-SLI problems

[myxoman]

I've just bought my first PC in "pieces". I have finished assembling it and switched it on. It starts up fine, all the fans spins and it looks ok. I'm able to access the BIOS, and after that it displays the "PCI Device Listing". But then it stops. It doesn't try to boot from any device. The cursor sits in the bottom left corner, blinking. It doesn't even respond to the Ctrl+Alt+Dlt command. What have I done wrong?

Any help is appreciated!

I have the following system:

AMD64 3500+ CPU
2*512Mb PC3200 Corsair memory
PowerColor x850XT videocard (PCIe)
400W NorthQ PSU
NEC DVD Recorder
Western Digital Caviar 250Gb S-ATA disk

First, set your memory voltage up manually in the bios to 2.70v. Second, what are the amp ratings on all the rails of your power supply?

OK, I just set the voltage for my memory to 2.70v. It didn't help. Here are my amp values:

Voltage +3.3V +5V +12V -5V -12V +5Vsb
Max Load 26A 35A 15A 0.5A 0.8A 2.0A
Min Load 0.5A 2.0A 0.5A 0A 0A 0A

You are never going to get your system stable with only 15a on the 12v rail, especially with that x850XT.

But for the sake of trying to get past the dmi pool data post, have you set up the sata port that you have the drive on? Are you using the Silicon Image (red) ports? or the NV sata (black) ports? To use the NV sata ports, you need to go to Advanced/Onboard Devices Configuration/NVRAID Configuration and enable RAID Enabled then enable the port you have the drive attached to.

That power supply is pretty crappy, even the "original Antec 300w" has 15A on the +12V rail.

Get the Antec 550EPS ps. it has 36A on the +12V rail and cost $113 about the best buy out their for a powerful single rail ps.

Thanks for the help. I never realised that different PSU had different "poer quality", I just thought comparing the Watt would be enough. I'll look into buying a new PSU.

I definitly have some problems with my S-ATA setup in my Bios. When I removed the disk it came through for me.

Again, thanks a lot for your input!

Amperage on the rails mean a whole lot more than the wattage. A generic 600w PSU would be outperformed by a quality 450w PSU.

 

[myxoman]

OK, how many Ampere on the 12V should I aim for?

 

[Waylay00]

I would say at least 24a
