Common advice for systems that are misbehaving is to run the "memtest" utility. Misbehaving symptoms include system lockup or freezing, random rebooting, or graphics/screen distortion.
Follow the steps below to complete the memory test.
Boot the system with the ASTi DVD (the one that is used for the Cold Start procedure) and then start the utility by typing "memtest" at the prompt (instead of "studio" or "target"). It is recommended that this runs through several times before declaring the system good from a memory perspective. ASTi recommends running the test over night.
Execute the Memory Test
Note: The memory test is available for ACE software versions 4.10 and later.
