Re: test a memory

What kind of errors?

There are 2 possible memory errors: single bit and double bit errors. In case of a (correctable) single bit error the system will decide to "reserve" this area of memory and won't use it any longer. You can run the diagnostics info tool (mstm/xstm) on memory and have a look into.

In case of a double bit error the system will reset immediately to prevent data corruption (TOC/HPMC).

Hope this helps!

Sorry, just copuldn't resist..

As others said, by using STM, you will be able to see the various types of memory errors. Single bit errors are common once in a while, however, if they are mounting up on the same module, I would suggest you get your hardware service provider to swap oyr the module as your are headed for problems.
