Quick question on how much ram to use on am3+

post #1 of 7
Thread Starter 
I have the gigabyte ud5 990fx and I already have 2 8gig dims already in dual channel and I recently started hitting close to using all my ram at once with the intensive programs I use for school. So I was wondering if the platform(mobo) can run 3 dim slots at once for 24GB. I know 32 GB is a lot and I will never use that much but 16GB of ram is starting to be not enough.

Can I do 3 modules on the mobo?

It should work, but it may prevent dual channel operation on the other two slots that are already populated... I'm not 100%

It will work but they will run in single channel mode.

i heard but never tried that if you run 3 sticks of ram 2 would be in duel channel and the last one will be in single. not sure if i wanna believe that but might as well just get 2 sticks to fill all the slots.

No. They will all run in single channel unless he has 2 or 4 sticks in the appropriate slots.

Maybe I'm thinking about if there was a 2gig stick and a 4gig stick that the first 2gigs of the 4 gig stick would be in duel channel and the rest in single.

Nah it'd still run in single. The system can only run in one or the other never both types.
