Q: iMac RAM slots 2x4GB 2x2GB

Hi,

I've just purchased an iMac (27''). There was some special offer for 8GB RAM, so they installed 2x4GB RAM into it and gave me the original 2x2GB RAM. The iMac works just great. When I turned it on I've checked the "About This Mac" and it says that there are 4 slots and just 2 of them are in use. Is it possible to add the 2x2GB original RAM into it? If so, where should I put which. Does matter whether I put the 2x4GB RAM into the upper slots and 2x2GB RAM into the lower slots or vice versa? Will it work? I don't want to screw it up

MacBook Pro, Mac OS X (10.7)

A:

With the machine laying face down, the upper is the top set...so the furthest back looking from the front of the machine, if I haven't made that confusing enough

Anyway, if the machine is down on its screen, then the upper is now on top.

From experience recounted on here in the past, keep the 2x4 in the upper slots and put the 2x2 in the lower...the critical thing is that the side-by-side slots are the same, the up and down can be different. And the top slots are the first accessed so the larger would be better there.

And you won't screw things up...the worst that will happn is the machine balk at starting and giving you three beeps saying it oblects to the memory.

However, it really should not do that since the memory is all approved to start with.
