| That's for qlogic cards, Mellanox ones seem to be much, much more stable. As I need to stress every card I just looking for a tool to make memory chips there under heavy load and, unfortunately, with not much luck. So what's the tool for diagnosing the cards?

There is no memory on the card, this is on-chip memory.  The only test
tool for it is a QLogic internal manufacturing test tool.

If you are seeing this more than once on the same card, you should get
the card replaced by contacting QLogic support.

Some memory errors are inevitable.  We try to recover from them, but not
all of them are recoverable (have a "known good" backup, or are known to
be safe to rewrite and continue).
