iMac F2-5300CL5S-4GBSQ

The memory should be compatible as it does meet the specifications. Send it in for RMA to see if a new module works better.

Will drop GSkill Tech a note, he knows what works with MACs better than I, don't want to suggest something that might not work

Yes the firmware is completely up-to-date.

Does your computer have the latest BIOS?firmware?

Hi,

I'm trying to figure out if my RAM (F2-5300CL5S-4GBSQ) is bad, incorrect, or not supported.

I have a Late 2007 iMac (model 7,1) that according to Apple only officially supports 2x2GB but many people have a 6 GB configuration and places like OWC sell "supported" 4 GB DIMMs.

When I install it and boot I get three beeps (signals bad RAM).

Any help would be appreciated
