I am wondering about ram for a single 1.8GHz G5 and that it comes with 256MB

256MB DDR400 SDRAM (PC3200) - 2x128MB

it comes with 2 x 128

Do I have to put RAM in the single in pairs because it only supports 4GB I think maybe there will just be 4 slots... but it comes with 2 sticks so I am lost :dummy:

Can anyone tell me? Thanks :mac:

iBook G3 (2001) 500MHz 384 RAM 9.2.2 / 10.2.8
Titanium PowerBook G4 (2001) 500MHz 768 RAM 9.2.2/10.2.8
Mac Pro (2007) 4x2.66GHz, 6GB RAM, 10.6.7
iPad 3G + iPhone 4

The 1.8 single processor comes with 4 slots. 2 of those slots are being used when the machine is shipped to you. Therefore you have 2 open slots. As far as I know you have to install in pairs altho I have conflicting reports direct from Apple. I am quite sure it's in pairs only. If you want more Ram you might have to do a trade out with a company that will exchange the Ram you have now for higher Ram. Of course you could just leave the 256MB you have and install 2 512MB Chips or 2 1GB Chips or 2 256MB Chips, etc. to get up to the Ram you desire.
QUOTE Thanks
