Well, but don't expect to much of that selftest.
Its only a semideciding process.
If it detects a problem, well you got it.
But if it doesn't, you can't tell they are good.

Have you tried to pull and re-insert all rams?
This often helps. Also permutating the order they are inserted might really help.

There was a bunch of educational promo ss4 / ss5 sold by sun, with poor ram.
(Sorry Sun, I have to say that, even so it was the only mistake in 15 years.)
Timing is tight with this rams.

So the above often helped. 

cheers Andreas
