Title: GA-X58A-UD3R will not go to post.
Post by: WolfSabre on August 04, 2011, 04:36:47 am

Hi there,

I've recently purchased a GA-X58A-UD3R, and it has been a nightmare.

The build:

i7-960 3.2GHz
Kingston DDR3 1333MHz 4GB
GA-X58A-UD3R Rev 2.0
GTX560 1GB
850W PSU

So, here is my problem; I plug everything in and it doesn't post.
The CPU fan is running, but very sluggish.
I have the 8 pin plugged in, I have the 24 pin plugged in (as securely as i can get it), and everything is seated right.
I've gone over the connectors on the GFX card and the RAM with iso.
The voltage between the ground and 12v pin on the cpu fan is ~6 volts.
I plugged a PCI debug LED in, and I get the codes: "b8 02 ea 01"
I don't believe its shorting on the case as I've got it out on a bit of cardboard, with it experiencing the same fault.
I pulled the RAM and booted and there was no beep code.
I've already replaced the board, and the CPU.
The next thing to try would be to replace the RAM, but seeing as I don't get a beep code with the RAM out I doubt that is where the fault lies.
I've tried the board with 2 other PSU's - same fault.
I tested the PSU's with a PSU testers, all is good there.
I've cleared the CMOS, both by using the clr cmos button on the back, and by draining excess power using the power button and pulling the battery.
Still no post.
Is there something I've missed? Any help would be appreciated greatly.

Regards,
- Wolf

Hi

Well it seems like you have checked most things out already but obviously there is something that has been missed.

I think an extended CMOS clear would be the next thing. Please follow these instructions exactly:

Remove the power cable from the mains supply and then press the power switch on the case for a few seconds just to drain any residual energy in the PSU capacitors.

Once done remove the motherboard battery for at least 5 hours before replacing it.
 
Next plug back into the mains supply and boot.
 
You will now need to enter the BIOS by pressing DEL and load Optimised BIOS Defaults.

Make any other changes to the BIOS settings to suit your self like disabling the floppy drive, disabling the full screen logo and making the HDD the primary boot device and then press F10 to save and exit.
