iMac RAM

Hi,
I currently have an Intel iMac 17" core duo and recently upgraded it from 1gb to 2gb. My question is this, will it make a difference that I am only using one 2gb stick rather than two 1gb sticks.
The only applications that I normally use are Office 08, Safari and Adobe CS3.

Thanks

some machines work slightly better in pairs but it can very from machine to machine. When you have two sticks the transfer on the ram bus is shared however bus speeds are at a higher speed these days to cope.

The notice is negligible.

It depends on which iMac you have.

The iMac "Core Duo" 1.83 17-Inch and iMac "Core Duo" 2.0 20-Inch -- the "iMac (Early 2006)" models -- shipped with "at least 512 MB of DDR2 SDRAM installed into the top slot" and can be upgraded to "2 GB total (a 1 GB SO-DIMM in each of the two slots)". There is not a performance penalty for populating a single slot or populating both slots with different capacity modules.

The iMac "Core Duo" 1.83 17-Inch (IG) and iMac "Core 2 Duo" 1.83 17-Inch (IG) -- the "iMac (Mid 2006)" and "iMac (17-Inch Late 2006 CD)", respectively -- shipped with "at least 512 MB of DDR2 SDRAM, in two 256 MB DIMMs; one in each of the memory slots" and also can be upgraded to "2 GB total (a 1 GB SO-DIMM in each of the two slots)". However, as these models use slower integrated graphics (IG) that "borrow" system memory, it is critical that you install two modules of equal capacity for optimum performance.

The iMac "Core 2 Duo" 2.0 17-Inch, iMac "Core 2 Duo" 2.16 20-Inch, and iMac "Core 2 Duo" 2.16 24-Inch -- the "iMac (Late 2006)" models -- shipped with "at least 512 MB DDR2 SDRAM installed into the top slot". There is not a performance penalty for populating a single slot or populating both slots with different capacity modules.

Thanks for the replies. It looks like I have the early 2006 version and that it won't make a performance difference.
Great link by the way, thanks
