Hello. I have a problem with booting on EP45T-EXTREME. I suspect eighter
the CPU or motherboard (since the only communication with the system in
through the motherboard I ask here):
- The diode showing CPU temperature is showing 60° C
- The diode showing CPU load is showing near 100% load
- The cpu fan move slightly at startup and after a few mm it stops (it moves
back on power-off). It is not due to some other fan (checked)
- The screen is blank
- The error code display is showing FF
The configuration:
- GA-EP46T-EXTREME as motherboard
- Core Quad 2 Q9650 3 GHz - Kingstone memory 1600 MHz DDR 3
- Gigabyte Radeon 4870x2
- 850 W power supply
Any ideas?

PS. I tried to use Gigabyte support center but I receive no response as far.
The motherboard has two power cables. The 24 pin one is for the motherboard
electrical loads. The 8 pin one is for powering the processor.
Yes. Both are connected.
The Debug
Display sitting at FF means the CPU has not executed any code.
Ok. That what I suspected.
The 8 pin power connector, can use either a four pin or an eight pin
power source. One page of the user manual, is dedicated to explaining
about the power connectors. If using the eight pin connector, you
can check the pin numbers against that shown in the manual. There should be
four identical yellow wires on one side and four black wires on the
other side. The yellow wires are +12V.
Although it is as you described in power supply manual actually 2 wires
(which are detechable to make 2x3 pin connector) are black from 'right'.
I'll try with different cable/PS Socket.
You can also use a four pin connector. The connector plugs into
pins 3,4,7,8.
If the power is fully connected, you can try a test with the
memory removed and the video card removed. Make sure you have
a computer case speaker connected to the F_PANEL header, so you
can hear "beeps" caused by the memory and video card being
unplugged. If you hear beeps, it means the CPU has executed
some code.
I didn't find case speaker (unless I can connect HD Audio or AC 97 - but
I don't think so). But I'll check the error code.
You should also be able to view a new value on the
debug display. The debug display shows "progress" codes and
not "error" codes. Before a subroutine executes in the BIOS,
the progress code is updated to indicate what happens next.
When the display gets stuck, that tells you what subroutine
it is stuck at.
It was called so in the manual so...
The best way to read the manual, is with the PDF version.
It is available from one of several Gigabyte websites.

I had read both the dead tree copy attached to motherboard as well as
this in hope it is updated and extended.
Regards and thanks for responding
