2MB RAM card tests
2004-03-12 by David J. Wilson
Aaron, it might not be the 2MB RAM cards that are faulty, but rather the channel cards. Peter W. said the channel cards should be be revved to 1.9A or 2.3A work with the WaveSuper. The RAM cards should be best be revved to 4.5 to work with WaveSuper here's an old e-mail from Peter on the 9.34 RAM card diag subject: ------------------------------------------------------------------ I don't think the corruption is due to the new software. With the new ROM set you can run diagnostics to check the RAM and channel cards. What I do is say, start off with one RAM card plugged in (you don't have to remove all the rest, just pull them out an inch), and run the tests. You do this in the following way: As the machine first boots, when you see the first info screen, hit the space bar. Quickly type d. It'll enter diagnostics now. Now type m (return) This will thrash all the channel cards (you'll see all their LEDs lit), whilst testing the memory. If you get five passes without errors, all's fine, other wise errors will show by scrolling up the screen. Each pass is about 20 minutes with 14 Mbytes, but obviously this changes with total memory amount. If you get errors with even one RAM card, it may be a channel card at fault. Remove some channel cards, remembering they have to be in a continuous "block", starting with chanels 1-2, which is on the right of the card cage. In other words, remove channel cards from the left of the block. Again you don't have to remove the cards, just slide them out by an inch, and leave their cables attached.
