Bad RAM, Mrs. Torrance?


That tone -- or series of notes -- indicates bad RAM in most cases. It could be something else. Are you comfortable going inside?

I'm pretty comfortable opening it up. Is it difficult to replace the RAM?

It's not hard to get at the se/30 RAM. You will have to take the logic board out. Get your T15 torx driver from Sears, lay the se/30 down on it's front (on a towel), and persuade the case to come apart. Some folks use a case opener, I use a spring clamp from Sears with the "jaws" flattened out into a duckbill. Just disconnect the SCSI connector, floppy connector, and power connector from the motherboard. Obviously remove any cards in the PDS slot. I don't remember any other fasteners holding the motherboard. It should slide right out. The RAM is immediately obvious. There are spring tabs on each side that you'll need to push in to release the SIMMs. The previous poster is correct, it is possible that you have some oxidation.

While you have the motherboard out, I'd look around for capacitors that are misshapen (bulging tops), or more commonly- leaking. Plan on replacing them. A decent web guide (that you may have seen) is:



128K, 512K, Mac Plus, Classic, SE/30, Indigo iMac, B&W, Sawtooth, iBook G4, Mini. Numerous SGI and Sun boxen.
