Hello all! I just upgraded my iMac 8,1 to 6 GB of ram. I put the 4 GB card in slot 0 and 2 GB in slot 1. Everything seemed register fine so I went ahead in upgraded the SSW to Lion. It was odd because only during the install of Lion when the system restarted I would hear a beeping sound and would have to manually shut it off and restart it. After the install finished the system restarted fine again also software update was run and it still restarted with that without fail. Is this something I should be worried about? The RAM I installed is called Hypervelocity and It should have a lifetime warranty but either way I would like to test the new RAM a bit more than just seeing 6 GB appear in system profiler.

Thanks,
Gary

Re: Lion + RAM installed with restart failures

Gary,

Is your iMac a newer model (Intel Processor), or an older model (Apple Processor)?

If it is an older model, you may have problems due to Lion (OS 10.6 I believe) was made to run on Intel Macs. This could give you some problems.

I'm just guessing here, but from what I have read that could be it.

Well, thats not the problem as Lion (10.7) will only install on an Intel C2D or better processor. it will only run in 64bit machines. that leaves out PPC chips

Thank you. I ran the plain memtest under single user mode and it failed the block sequential part of the test then froze. Manually restarting it caused the beeping sound again. The RAM is unfortunately defective.

Re: Lion + RAM installed with restart failures

The place I bought it from had me test both cards 1 at a time to find the bad one. When the 4 GB card was installed by itself the iMac wouldn't even start up. Its strange that when they were both installed it still showed 6 GB registering and the system never crashed once other than the restart failures. I hope this bad card didn't corrupt my install of Lion at all...

Re: Lion + RAM installed with restart failures

Received the replacement and everything works good now! This iMac likes the 2GB card in slot 0 and the 4GB in slot 1. It didn't want to work the other way around...
