Cache SIMM error Power Mac 6100
Posted by: joshc on 2022-06-03 17:31:14
Has anyone ever had an error at boot that says:

"The built-in memory test has detected a problem with the cache SIMM. Please contact a service technician for assistance."

This appears after the Happy Mac/Welcome to Macintosh screen and before the main extensions loading screen when booting with System 7.5.5 on my Power Mac 6100.

I didn't know that Mac OS could display any memory-related errors at this point in the boot process, let alone a user friendly dialog box.

Yes. I’ve seen it before. When it happened and I shut down the 6100 after, the cache SIMM was so hot I couldn’t even hold it.

I have an MDD G4 CPU card which prompts a similar message at the same point in the OS 9 boot process. OS X says nothing and simply runs without any L2 cache detected.

If anyone found a seller for these PM6100 cache-Simms with 512K or better 1M, please let me know. Thx!
