View Full Version : FC3 64 + 4GB RAM = Unstable System ???
1st December 2004, 05:24 AM
I have a Tyan Tiger K8W (S2875) with two Opterons and just
installed FC3 64. Previously I was running FC2 32bit.
After installing FC3 64, my system crashes almost immediately
after booting. Removing two of the 4 Crossair 1GB simms,
fixes the problem. Any ideas suggestions how I can get the system
stable with 4GB ? I did not have this problem with FC2 32bit.
I tried recompiling the kernel (I was using 2.6.9 with FC2)
and that did not help either.
I have a low end Nvidia Video Card and 4 SATA drives.

I am still having this 4GB problem. Whenever I install 4GB of
memory my system crashes.
No problems whatsoever with 2GB of main memory. When I install
4GB of memory, I can boot and login in safe mode or tty. As soon
as I start an application that uses some more (?) memory the
kernel panics. I presume the same thing happens when I start X,
only there I never get to see the kernel panic message, the
system just hangs. So the boot process is ok, it's the memory
usage that seems to be fishy ....
So I suspect there is something funny about the kernel, or some
of it's parameters. I have run memtest86 for an entire day, no
hardware/memory problems where reported.
At this point I am very certain this is a kernel problem. Any
kind soul with suggestions/ideas, etc ?
Anybody else using 4gb of memory ?

Hmm..wow. I have that exact same MoBo and 2 opterons with 4 gigs of memory...I haven't recieved my heatsinks for my processors yet but am planning to install FC3_64 as soon as I do.
I will post what happens as soon as I get it all set up.

Did you check your memory timings? You may have to lower them possibly? Also did your system crash running the 32 bit version of fedora with 4GB of memory?

OK, I powered on my system and tried to install Windows XP, but as soon as it starts looking at my hardware it locks up....FC3_64 works just fine (so far) and I cannot find a chipset driver for Windows XP 64-bit Edition which installed with no problems.
Have you tried anything aside from Fedora?
