I am trying to follow up your suggestions but have few problems.

I think I do have the latest, but am not sure.
Explanation: asus site provides two latest BIOS revisions: 0301 
for DOS, and 0203 for all OS's.  I've got 0203 (according to 
dmidecode) so I think this is fine.

I rebooted into rescue mode but can't find memtest, only 
memtest-setup.  According to some reading (oh! it's already 
midnight here) I should do:

* reboot again to rescue (because I have mounted fs read-only)
* chroot /mnt/sysimage
* run memtest-setup (to get a memtest86 entry in grub)
* reboot to memtest86 in grub

Is this correct?
Or maybe I should just reboot to centos, yum install memtest and 
continue from there?

Thanks so much.
