24GB RAM question

I have 4x4GB in plus 2x4GB = 24GB in 8 slots. It's a quad channel MB. Is this setup effectively triple channel even though all 8 are filled (I thought it would be quad channel)? Or is it solely the total amount of ram you have that determines if you have dual, triple or quad?
 
It's usually the slots being populated which determinds what the ram runs at. Check the manual, this will show the what's slots are used and how they run.
 
Am at work at the moment but will check the manual later. This is what I thought, though.

Hopefully have some more answers by then.

Thanks for the response, RJC. :)
 
Just checked the manual.

It kind of answers my question - "To ensure system stability for multi-channel mode (dual/ triple/ quad channel mode), memory modules must be of the same type, number and density."

When it says density, does it mean the bandwidth or the capacity?
 
hmmm I would suggst capacity but even more than that

I dont know about now, but a few years ago you could quite easily get single sided ram in same over all capacities as double sided ram, but while either would work in most motherboards, they would rarily if ever work together.
 
Entirely ineffective.

That seems a strong way of putting it.

Using the correct slots on the motherboard 6 DIMMs will operate in triple channel mode.

It's not optimal but it's not "entirely ineffective".

Other than in synthetic benchmarks I doubt he'd really notice the difference between triple and quad channel anyway.
 
Entirely ineffective? As in the extra 8GB (4x2) or the setup as a whole?

I don't think there's any point in having more than 16GB anyway but the thing is when I ordered my bundle I was expecting 8GB so I decided to order an extra 8GB on top. Turns out I got 16GB with the bundle instead and I already ordered the 8GB before I received the bundle so.... I was too lazy to send the extra back and decided to install it. :D

Truthfully I find my PC to be insanely fast and I never go above 20% physical memory usage (10% or so at idle) so either way I'm happy.

Oh I just checked on CPU-Z it says it's quad channel so I'm guessing it's running in quad. Cheers guy. :)
 

Thank you for the link - it was very informative.

Just one thing it doesn't seem to explain. For me, does this mean that one channel is operating in quad and the other in dual? Or is it a different combination?

Is my speed reduced at all? If so, I will just remove the other 2x4s and possibly sell them or buy a DDR3 board for my spare PC and fit those inside.
