Does my pc support quad channel RAM

[Riley77]

I have 4 slots for RAM, but am not sure if my pc supports quad channel ram. I ran CPUZID and it says I'm currently using dual channel. If my pc supports quad channel do I have to change from dual channel to quad channel in a BIOS setting? Or does the pc auto adjust when more RAM is added. I'm aware that you are not allowed to mix a DDR1 with like a DDR2 for example for RAM, but does that mean my graphics card has to be the same as well? If anybody has any suggestions on RAM to buy I would appreciate it as I am trying to upgrade.

Why is there 4 slots if it can only be used with 2?

For more ram upgrades.

So correct me if I'm wrong lmao I have 4 slots, I can use them all at the same time, correct?

Yes you can.

You can use all four. It will use all four slots if they are all populated but it will use the RAM modules in pairs, i.e. it will access them two at a time simultaneously.

If it were a quad channel system it would access all four modules simultaneously.

Yes you can.

Okay thank you, I thought dual channel meant just 2 slots and I thought 4 slots would be quad channel, now I understand that I have 4 slots which allows for dual channel.
