On some systems you will notice that timer channel one count down fails. This is normally caused by a faulty system BIOS. Most of the time, a simple BIOS upgrade or re-flash, should fix the problem. If you are unable to flash the BIOS and the failure persists, the system may be able to tolerate if the failure occurs less than 35% of the time. If the failure is more than 35% of the time, then you will encounter memory problems. The timer channel one controls the refresh cycle for memory.
