putting old Macbook RAM in an iMac. Good idea?

Happy holidays!

I ordered some RAM through newegg and I have just maxed out my Macbook and have ordered some extra RAM to give to my mom for her iMac. I have checked and both my 3.1 Macbook accept the same DDR2 SO-DIMMS at 667 Mhz.

She currently has only a single 1 GB stick installed. I have bought her a 2GB and I have my 2 X 512MB sticks collecting dust. Since the iMac has 4 RAM slots, should I give her my old RAM thus giving her a 2 + 1 + 512mb + 512mb configuration?

Also, is it important that the RAM be placed in the memory banks in descending order? If so, how can I recognise which slot correcsponds to bank 0, 1, 2 and so forth.

Thanks!

as long as the ram has all the same specs it should work. in general it's better to install ram in matched pairs, but i don't think the imac is terribly picky with it's ram configurations. there might be a slight decrease in the efficiency of the ram because of the mismatched pair, but i can't see it being a huge issue.

This is not a pair though. It's a foursome (no pun intended)! An unmatched 2GB and 1GB stick and in the remaining 2 slots would be a matched paire of 512mb sticks.

i don't think it will matter, but i just briefly looked at everymac.com - are you certain the imac has 4 slots? it seems that the only imacs with 4 slots were 2009+ models....which use ddr3 ram....so double check that you have the correct specs.

you are correct. The iMac in question is mid 2007 so there are only 2 RAM slots upgradabe to a maximum of 4GB RAM. I wonder what use there might be for my old RAM? Garbage?

I was going to question the number of RAM slots you stated in that Imac, as that's close to the same model I'm using but i-rui beat me to it.

And BTW: Her mid-2007 iMac can probably actually use up to 8GB installed RAM which would probably be overkill for her use, but the 2GB+512MB sticks should make a big improvement.

For the surplus 512MB chips, make them into a keychain for the grandkids which is really easy if they are of the type with holes just already waiting for a small keychain chain.

I think you'll find that Apple with all the various parts they use got "the lead out" years ago.

And gee, I should be dead by now for all the lead ridden toys we grew up with and handled and all the lead fishing weights and all the various lead dealings with various equipment repairs etc. through the years, and oh yes, the very heavy small bottle of mercury we would play around with.

And I almost forgot the copper/lead/arsenic anti-fouling paint we used on our west coast boats and then just washed off any skin splashes with a petroleum solvent, and oh yes, the asbestos rock samples my sister and I would pull apart that our father had brought back from Ontario before we were born after doing his electrical engineering apprentice there...

I'm sure there are more.... And we'er both still alive and surviving seniors!!

Any memory produced in the last 5 years or more is ROHS compliant which means no lead in the solder.
