Hi, Without 1) openning the box, or 2) rebooting (really it's 1), but...) is there an easy way to tell whether a machine has ECC RAM or not? Thanks a zillion, Alvaro Novo SuSE 7.1 Pro -=- Kernel 2.4.0-64GB-SMP -=- KDE 2.2-beta1 4:10pm up 27 days, 4:28, 2 users, load average: 1.02, 1.04, 1.00

Yes, Get the Linux ECC module from here: http://www.anime.net/~goemon/linux-ecc/ Follow the build and insmod instructions then you can do: cat /proc/ram and this will tell you something like this if you have ECC ram and if the board is ECC capable (and if ECC is enabled in the BIOS...). cat /proc/ram Chipset ECC capability : ECC detection and correction Current ECC mode : ECC detection and correction Bank Size Type ECC SBE MBE 0 128M SDR Y 0 0 Total 128M Matt

Thats typical :-).

Sounds like you made a new kernel that is 2.4.2-64GB-SMP. A lot of memory huh? and Dual Processor? Two causes I can think of: a) You compiled ecc.o on a different machine, not the server, and the machine that is was compiled on was "pure" 2.4.2 b) If it was compiled on the server then your header files do not match the kernel that is running. Anyone remember how to fix this? Hope that helps! Matt

Yes, it was compiled on the server where I am "insmod"; and, the kernel is SuSE's (an rpm update). Strange... Alvaro Novo SuSE 7.1 Pro -=- Kernel 2.4.7-4GB -=- KDE 2.2-beta1 11:44pm up 3 days, 22 min, 1 user, load average: 0.00, 0.00, 0.00

Your module was compiled on a uniprocessor machine. you are trying to use it on a multiprocessor machine, you can't. recompile it on your smp machine.

No, it was actually compiled on the dual-processor machine. I guess the ecc module does not support the chip or eventually smp kernel.... Thanks, though. Alvaro Novo SuSE 7.1 Pro -=- Kernel 2.4.0-64GB-SMP -=- KDE 2.2-beta1 9:28am up 27 days, 21:46, 1 user, load average: 1.03, 1.08, 1.04

you compiled your module against a kernel whose version number is '2.4.2'. I assume you compiled this kernel yourself, so no one knows if you set it up for SMP. You should try compiling it agains the kernel sources configured for the kernel you are running. Try this: (boot to 2.4.2-64GB-SMP) cd /usr/local/linux make cloneconfig make dep (recompile your ecc module) modprobe ecc.o rafael
Some BIOSes will tell you on boot when the screen that says the hardware layout comes up. They will show something like bank 0,1 ECC Depending on the bios.

is there an easy way to tell whether a machine has ECC RAM or not?
