Is there a bios update available for that mobo?

I have been getting strange failures from time to time, especially when
recompiling the kernel. It gets about 10 minutes into it and then reboots.
It is a Phenom 9850 Gigabyte motherboard.
Finally I set the BIOS setting to the failsafe settings, instead of
the optimized settings. That cured the problem!
So I guess that the settings to choose are somewhere between the two.
"Optimized" isn't really optimal unless it always works!

The final word:
For a time it was just a nusiance, since I wasn't doing that much heay
compiling besides the kernel, which I didn't recompile for a while.
But then I got to compiling a lot of stuff and it became a serious
problem.
E.g. if you install a new level of gcc, it compiles for 3 or 4 hours,
which was just not feasible.
So ..
1. I removed the cpu heat sink, and found that it had
more silver paste than was necessary.
I then cleaned it all off and put only about a 2 mm diameter
spot in the middle of the cpu, reinstalled the heat sink.
That did not cure the problem. It rebooted after a couple of
minutes into the kernel compile.
2. I finally got all the bios update files for the motherboard,
2 of which are new, levels f6 and f7.
3. Using a usb fd, I flashed bios level f6.
After that, following the directions, I restored the bios
optimized defaults.
Then it wouldn't boot. 1 long and 3 shorts told me that it was
a graphics problem. Black screen.
Using a PCI video card instead of the PCI express cured that problem.
4. Then I recompiled the 2.6.28.8 kernel level, which took about
12 minutes for this configuration. It takes about 25 minutes if I
compile every module there is.
No problem.
5. Then I compiled the 2.6.28.8, 2.6.29.1, 2.6.29.2, and 2.6.29.3
kernels all at the same time.
It ran about 90% of all 4 cpus busy, and they all completed
in 14 minutes, using about 2.7G of memory.
I think that fixed it. I still have to figure out why the PCI express
isn't working, but that seems like an easy problem now.
Maybe I'll flash the f7 level too, after I see what it fixes.
