One small mistake on my site. If you want 8GB of RAM use a i5 System. (not really slower than a i7 system, just different specs) or with a i7 system use 6Gb of RAM or 12 Gb of RAM. (The i7 has a tripple channel interface and so needs RAM in pairs of three. ( 3 x 2GB, 6 x 1GB , 6 x 2 GB , 3 x 4GB or 6 x 4GB)
This has me perplexed.
Do all channels have to be the SAME size, AND all the channels have to be filled?
OR, do all the channels have to be the same size, and can I use only two channels?
The reason I ask is, there are some common manufacturers that seem to be using 8gb ram with the I7 and offer a free upgrade to 9gb.
On its surface seems like a good deal to get an extra gb.
But, will I have to get all new ram to upgrade f I use 3x3gb?
So how do they set up ram?
Is it 2 x 4 gb on 2 channels of an I7 that has 8gb total ram as spec?
Therefore wouldn't it be prudent to get 8gb to make an upgrade to 12gb later more painless?
Am I just off base or worse ignorant as all get out?
OK I'm looking for long term upgradability as an option.
Thanks for any help,
