So I decided to put together a new system with 24gb ddr3 memory and I wanted to test the memory. Unfortunately, the knoppix 7.5 memtest boot option crashes on the AMD 760G motherboard.
Why not make a huge file in the knoppix ramdisk and run a badblocks on it?
dd_rescue /dev/zero ~/gigafile -m 20G
to make a 20 gigabyte file, but it fills up the memory before it gets to 20GB.
badblocks -w -s ~/gigafile
to run a check on the big file.
Nota Bene: be careful with dd_rescue and badblocks. I remember this time I was a little careless with the parameters and wiped my hard drive...good thing I had a backup.
Man, do I love having lots of memory. I think it was processing at around 2.5 GB/sec.
My first attempt at making a huge file was in the temp directory /tmp/gigafile but it wouldn't let me make a file larger than about 2GB in /tmp.
Now if I can figure out how to put this thing in standby. "sudo pm-suspend" suspends it but it comes out of suspend immediately...
