quad-channel DDR3 Ram

[lukasrudolph8]

I have an Optiplex 780 with a Intel Core 2 Quad Q9550 @ 2.83GHz. does my pc supports quad-channel ram ? Here it is:

No, that will be a dual channel system. You can install four memory sticks up to the maximum memory supported though, which I believe would be 4x4GB (16GB) of memory.

Thanks for the fast anwser but isnt it 4x2 ?

That looks like dual channel kit from 2 modules + 2 individual modules (not quad channel kit).
Probably will work on your system. But as noted before - can work only in dual channel or single channel mode.

Motherboard is dual channel.
It can run 4 modules in dual channel mode.
4 modules is not the same thing as quad channel.

4x2GB would be 8GB total memory if that is what you are asking? You will have four sticks of memory operating as 2 banks of 2 memory sticks. Dual channel.

If you want 8 GB, then it is more efficient to get two 4GB sticks, less memory to power.

The number of memory sticks is not equal to the number of channels. triple, quad, hex, and eight channel setups are only found on the High End Desktop platforms like Intel's or AMD's X series motherboards.

oh ok. but quad-channel kit would work ?

Dell specs says - it supports 2GB modules. 4GB modules may not be supported.

Hmm, some conflicting info:

http://www.crucial.com/usa/en/compatible-upgrade-for/Dell/optiplex-780-small-form-factor (also covered the other ones)

I know some Q6600 boards from that era took 4GB DIMMs, I don't see why those wouldn't.

Might be a matter of sticking with single sided DIMMs.
