Hi Guys,
Have an issue with out of the box components using a Sabertooth x79, where the RED CPU LED stays on.

PARTS:
- Sabertooth X79
- i7 3930k
- 4x8GB Corsair XMS 1600 DDR3 - CMX32GX3M4A16
following correct configuration: http://i1013.photobucket.com/albums/...ad_Channel.gif
however, not in suported list:
http://www.asus.com/Motherboards/Int...TOOTH_X79/#MSL
- 2 SATA 6GB Drive + 1 SATA 3GB DVD
- 1000W OCZ ZX PSU
- GEFORCE 9800 (PCIe) - working on other machine

ISSUE:
Machine powers up...
Fans spin, mobo get power (and green stand-by LED)
DVD can open (if connected),
etc...
However, red CPU LED is on everytime

STEPS COMPLETED:
- Disconnected all SATA, everything unplugged except CPU, GPU & RAM.
- Removed Noctua Heatsink/Fans , verified CPU installed correctly (triangle to correct corner, etc.)
- Ensure RAM is in correct bays (albeit model not on ASUS supported list)
- Downloaded BIOS 1203 and flashed using USB Stick as "SABERX79.ROM"
note: not .CAP because previous BIOS version installed)
& following ASUS steps: http://event.asus.com/2012/mb/USB_BIOS_Flashback_GUIDE/


Potentially the RAM is incompatible...
However, there is no DRAM red LED so cannot know 100%
Are there any other troubleshooting steps you can help with in terms of the RED CPU LED?

no need to dig into this one guys. received some learned simple advise on another forum and it solved my problem...

With patience ...
I striped down to empty shell once more, ensured all stand-offs in place, ensured all connections again 1 by 1 and viola can boot to BIOS.
Advice from this is... remember the stand-offs and pay extra attention when sitting the mobo (don't rush to the good stuff )
Am so happy it something so simple...
