I have never seen a document that describes how to interpret the 201 fault codes that can happen at power-up on a pc. For example, if the power up test stops with "60D4 201" displayed on the screen, all I can tell you is that we have a bad memory chip. Can some kind soul shed some light on how to interpret the first 4 or more digits? Which bank and which chip, and why? Thanks in advance, Neal Pollack SMC Telecomm 213-450-5150 x9845

I've seen ads for software that purport to be able to tell you the exact chip that is defective. Check-it, QA Plus diagnostics, amont among others. It apparently helps if you have a real IBM, as the clones don't follow standards exactly, in all cases. There are programs that do what you ask.

This number is usually / always correct. However, the rest of the info, or any software perports to being able to identify the defective chip further is best guessing. Some best guess better than others. If it's a soft error (most common) the best guess is pretty lousy. If it's a hard error the best guess is pretty close or good. If the error is actually in row 0, I don't believe any software in the world exists to identify the defectice chip better than 1/9. Most commonly, rows of chips come from the same mfg lot. My experience indicates that the tend to develope soft errors in close time related batches. al
