This is odd. My brother just bought a 1ghz Combo eMac with 128mb as standard (why Apple why!?). I ordered another 256mb from Crucial, put it in and it's disabled the 128mb stick - it just shows 256mb in total, and in Sys Profiler it says the other slot is empty. I swapped them round, no difference. Any clues anyone? Are they mismatched RAM types?

Profiler says:

DIMM1/J1601:

Size: 256 MB
Type: SDRAM
Speed: PC133U-322

Any help much appreciated.

Side note: The eMac flies with 256mb, yet with only 128mb it was a beachball spinning joke. Apple need their head tested sometimes...

I guess I need to run Sys Profiler with just the Apple RAM in to see what spec it says it is? All very odd.

Does the machine still recognize the 128MB if you pull the 256MB out? If it does, I would call Apple Tech support. If it does not, the RAM module may have had problems and you should "bring the machine in."

I'm going to try that tonight out of curiosity. Both slots work OK - could it be mismatched RAM types?

mismatched RAM types? not that I'm aware of.

I ran the hardware test cd and it can see both dimms, but reports the Apple one as 0/128mb, i.e. it's 'turned off'.

This is ever more bizarre. Just checked his eMac again and now all the RAM is showing. Huh?
